Principles of intelligent urbanism

From Wikipedia, the free encyclopedia

Principles of intelligent urbanism (PIU) is a theory of urban planning composed of a set of ten axioms intended to guide the formulation of city plans and urban designs. They are intended to reconcile and integrate diverse urban planning and management concerns. These axioms include environmental sustainability, heritage conservation, appropriate technology, infrastructure-efficiency, placemaking, social access, transit-oriented development, regional integration, human scale, and institutional integrity. The term was coined by Prof. Christopher Charles Benninger.

The PIU evolved from the city planning guidelines formulated by the International Congress of Modern Architecture (CIAM), the urban design approaches developed at Harvard's pioneering Urban Design Department under the leadership of Josep Lluis Sert, and the concerns enunciated by Team Ten. It is most prominently seen in plans prepared by Christopher Charles Benninger and his numerous colleagues in the Asian context (Benninger 2001). They form the elements of the planning curriculum at the School of Planning, Ahmedabad, which Benninger founded in 1971. They were the basis for the new capital plan for Thimphu, Bhutan.

Axioms

Principle one: a balance with nature

According to proponents of intelligent urbanism, balance with nature emphasizes the distinction between utilizing resources and exploiting them. It focuses on the thresholds beyond which deforestation, soil erosion, aquifer depletion, siltation and flooding reinforce one another in urban development, saving or destroying life support systems. The principle promotes environmental assessments to identify fragile zones, threatened ecosystems and habitats that can be enhanced through conservation, density control, land use planning and open space design (McCarg: 1975). This principle promotes life cycle building energy consumption and pollutant emission analysis.

This principle states there is a level of human habitation intensity wherein the resources that are consumed will be replaced through the replenishing natural cycles of the seasons, creating environmental equilibrium. Embedded in the principle is contention that so long as nature can resurge each year; so long as the biomass can survive within its own eco-system; so long as the breeding grounds of fauna and avifauna are safe; so long as there is no erosion and the biomass is maintained, nature is only being utilized.

Underlying this principle is the supposition that there is a fragile line that is crossed when the fauna, which cross-fertilizes the flora, which sustains the soil, which supports the hillsides, is no longer there. Erosion, siltation of drainage networks and flooding result. After a point of no return, utilization of natural resources will outpace the natural ability of the eco-system to replenish itself. From there on degradation accelerates and amplifies. Deforestation, desertification, erosion, floods, fires and landslides all increase. 

The principle states that blatant "acts against nature" include cutting of hillside trees, quarrying on slopes, dumping sewage and industrial waste into the natural drainage system, paving and plinthing excessively, and construction on steep slopes. This urban theory proposes that the urban ecological balance can be maintained when fragile areas are reserved, conservation of eco-systems is pursued, and low intensity habitation precincts are thoughtfully identified. Thus, the principles operate within the balance of nature, with a goal of protecting and conserving those elements of the ecology that nurture the environment. Therefore, the first principle of intelligent urbanism is that urbanization be in balance with nature.

Principle two: a balance with tradition

Balance with tradition is intended to integrate plan interventions with existing cultural assets, respecting traditional practices and precedents of style (Spreiregen: 1965). This urban planning principle demands respect for the cultural heritage of a place. It seeks out traditional wisdom in the layout of human settlements, in the order of building plans, in the precedents of style, in the symbols and signs that transfer meanings through decoration and motifs. This principle respects the order engendered into building systems through years of adaptation to climate, to social circumstances, to available materials and to technology. It promotes architectural styles and motifs designed to communicate cultural values. 

This principle calls for orienting attention toward historic monuments and heritage structures, leaving space at the ends of visual axis to “frame" existing views and vistas. Natural views and vistas demand respect, assuring that buildings do not block major sight lines toward visual assets. 

Embedded in the principle is the concern for unique cultural and societal iconography of regions, their signs and symbols. Their incorporation into the spatial order of urban settings is promoted. Adherents promote the orientation and structuring of urban plans using local knowledge and meaning systems, expressed through art, urban space and architecture. 

Planning decisions must operate within the balance of tradition, aggressively protecting, promoting and conserving generic components and elements of the urban pattern.

Principle three: appropriate technology

Appropriate technology emphasizes the employment of building materials, construction techniques, infrastructural systems and project management which are consistent with local contexts (situation, setting or circumstances). People's capacities, geo-climatic conditions, locally available resources, and suitable capital investments all temper technology. Where there are abundant craftspeople, labour-intensive methods are appropriate. Where there is surplus savings, capital intensive methods are appropriate. For every problem there is a range of potential technologies, which can be applied, and an appropriate fit between technology and other resources must be established. Proponents argue that accountability and transparency are enhanced by overlaying the physical spread of urban utilities and services upon electoral constituencies, such that people’s representatives are interlinked with the urban technical systems needed for a civil society. This principle is in sync with "small is beautiful" concepts and with the use of local resources.

Principle four: conviviality

The fourth principle sponsors social interaction through public domains, in a hierarchy of places, devised for personal solace, companionship, romance, domesticity, "neighborliness," community and civic life (Jacobs:1993). According to proponents of intelligent urbanism, vibrant societies are interactive, socially engaging and offer their members numerous opportunities for gathering and meeting one another. The PIU maintain that this can be achieved through design and that society operates within hierarchies of social relations which are space specific. The hierarchies can be conceptualized as a system of social tiers, with each tier having a corresponding physical place in the settlement structure.

A place for the individual

A goal of intelligent urbanism is to create places of solitude. These may be in urban forests, along urban hills, beside quiet streams, in public gardens and in parks where one can escape to meditate and contemplate. According to proponents, these are the quiet places wherein the individual consciousness dialogues with the rational mind. Idle and random thought sorts out complexities of modern life and allows the obvious to emerge. It is in these natural settings that the wandering mind finds its measure and its balance. Using ceremonial gates, directional walls and other “silent devices" these spaces are denoted and divined. Places of the individual cultivate introspection. These spaces may also be the forecourts and interior courtyards of public buildings, or even the thoughtful reading rooms of libraries. Meditation focuses one's thought. Intelligent urbanism creates a domain for the individual to mature through self-analysis and self-realization.

A place for friendship

The axiom insists that in city plans there must be spaces for “beautiful, intimate friendship" where unfettered dialogue can happen. This principle insists that such places will not exist naturally in a modern urban fabric. They must be a part of the conscientious design of the urban core, of the urban hubs, of urban villages and of neighborhoods, where people can meet with friends and talk out life’s issues, sorrows, joys and dilemmas. This second tier is important for the emotional life of the populace. It sponsors strong mental health within the people, creating places where friendship can unfold and grow.

A place for householders

There must be spaces for householders, which may be in the form of dwellings for families, or homes for intimate companions, and where young workmates can form a common kitchen. Whatever their compositions, there must be a unique domain for social groups, familiar or biological, which have organized themselves into households. These domestic precincts are where families live and carry out their day-to-day functions of life. This third tier of conviviality is where the individual socializes into a personality. 

Housing clusters planned according to this axiom create a variety of household possibilities, which respond to a range of household structures and situations. It recognizes that households transform through the years, requiring a variety of dwellings types that respond to a complex matrix of needs and abilities, which are provided for in city plans.

A place for the neighborhood

Smaller household domains must cluster into a higher social domain, the neighborhood social group. Good city planning practice sponsors, through design, such units of social space. It is in this fourth tier of social life that public conduct takes on new dimensions and groups learn to live peacefully among one another. It is through neighborhoods that the “social contract" amongst diverse households and individuals is sponsored. This social contract is the rational basis for social relations and negotiations within larger social groups. Within neighborhoods basic amenities like creches, early learning centers, preventive health care and rudimentary infrastructure are maintained by the community.

A place for communities

The next social tier, or hierarchy, is the community. Historically, communities were tribes who shared social mores and cultural behavioral patterns. In contemporary urban settings communities are formed of diverse people. But these are people who share the common need to negotiate and manage their spatial settings. In plans created through the principles of intelligent urbanism these are called urban villages. Like a rural village, social bonds are found in the community management of security, common resources and social space. Urban villages will have defined social spaces, services and amenities that need to be managed by the community. According to proponents of intelligent urbanism these urban villages optimally become the administrative wards, and therefore the constituencies, of the elected members of municipal bodies. Though there are no physical barriers to these communities, they have their unique spatial social domain. Intelligent urbanism calls for the creation of dense, walkable zones in which the inhabitants recognize each other’s faces, share common facilities and resources, and often see each other at the village centre. This fifth tier of social space is where one needs initiative to join into various activities. It is intended to promote initiative and constructive community participation. There are opportunities for one to be involved in the management of services, and amenities and to meet new people. They accommodate primary education and recreation areas. Good planning practice promotes the creation of community places, where community-based organizations can manage common resources and resolve common problems.

A place for the city domain

The principles of intelligent urbanism call for city level domains. These can be plazas, parks, stadia, transport hubs, promenades, "passages" or gallerias. These are social spaces where everyone can go. In many cities one has to pay an entrance fee to access “public spaces" like malls and museums. Unlike the lower tiers of the social hierarchy, this tier is not defined by any biological, familiar, face-to-face or exclusive characteristic. One may find people from all continents, from nearby districts and provinces and from all parts of the city in such places. By nature these are accessible and open spaces, with no physical, social or economic barriers. According to this principle it is the rules of human conduct that order this domain’s behavior. It is civility, or civilization, which protects and energizes such spaces. At the lower tiers, one meets people through introductions, through family ties, and through neighborhood circumstances.

These domains would include all freely accessible large spaces. These are places where outdoor exhibits are held, sports matches take place, vegetables are sold and goods are on display. These are places where visitors to the city meander amongst the locals. Such places may stay the same, but the people are always changing. Most significant, these city scale public domains foster public interaction; they sponsor unspoken ground rules for unknown people to meet and to interact. They nurture civic understanding of the strength of diversity, variety, a range of cultural groups and ethnic mixes. It is this higher tier of social space which defines truly urbane environments.

Every social system has its own hierarchy of social relations and interactions. Intelligent urbanism sees cyberspace as a macro tier of conviviality, but does not discount physical places in forging relationships due to the Internet. These are reflected through a system of ‘places’ that respond to them. Good urban planning practice promotes the planning and design of such ‘places’ as elemental components of the urban structure.

Principle five: efficiency

The principle of efficiency promotes a balance between the consumption of resources such as energy, time and fiscal resources, with planned achievements in comfort, safety, security, access, tenure, productivity and hygiene. It encourages optimum sharing of public land, roads, facilities, services and infrastructural networks, reducing per household costs, while increasing affordability, productivity, access and civic viability. 

Intelligent urbanism promotes a balance between performance and consumption. Intelligent urbanism promotes efficiency in carrying out functions in a cost effective manner. It assesses the performance of various systems required by the public and the consumption of energy, funds, administrative time and the maintenance efforts required to perform these functions.

A major concern of this principle is transport. While recognizing the convenience of personal vehicles, it attempts to place costs (such as energy consumption, large paved areas, parking, accidents, negative balance of trade, pollution and related morbidity) on the users of private vehicles.
Good city planning practice promotes alternative modes of transport, as opposed to a dependence on personal vehicles. It promotes affordable public transport. It promotes medium to high-density residential development along with complementary social amenities, convenience shopping, recreation and public services in compact, walkable mixed-use settlements. These compact communities have shorter pipe lengths, wire lengths, cable lengths and road lengths per capita. More people share gardens, shops and transit stops.

These compact urban nodes are spaced along regional urban transport corridors that integrate the region’s urban nodes, through public transport, into a rational system of growth. Good planning practice promotes clean, comfortable, safe and speedy, public transport, which operates at dependable intervals along major origin and destination paths. Such a system is cheaper, safer, less polluting and consumes less energy.

The same principle applies to public infrastructure, social facilities and public services. Compact, high-density communities result in more efficient urban systems, delivering services at less cost per unit to each citizen.

There is an appropriate balance to be found somewhere on the line between wasteful low-density individual systems and over-capitalized mega systems. Individual septic tanks and water bores servicing individual households in low-density fragmented layouts, allow the use of filtered greywater for free irrigation of gardens, but, if not maintained, can cause a local pollution of subterranean aquifer systems. The bores can dramatically lower ground water levels especially during droughts. The vantage of septic tanks an bores is to be managed by the very users, at no cost for the community. Alternatively, large-scale, citywide sewerage systems and regional water supply systems are capital intensive and prone to management and maintenance dysfunction, if not corruption or extortion by private companies. Operating costs, user fees and cost recovery expenses are high. There is a balance wherein medium-scale systems, covering compact communities, utilize modern technology, without the pitfalls of large-scale infrastructure systems. This principle of urbanism promotes the middle path with regard to public infrastructure, facilities, services and amenities.

When these appropriate facilities and service systems overlap electoral constituencies, the “imagery" between user performance in the form of payments for services, systems dependability through managed delivery, and official response through effective representation, should all become obvious and transparent. 

Good city planning practices promote compact settlements along dense urban corridors, and within populated networks, such that the numbers of users who share costs are adequate to support effective and efficient infrastructure systems. Intelligent urbanism is intended to foster movement on foot, linking pedestrian movement with public transport systems at strategic nodes and hubs. Medium-scale infrastructural systems, whose catchment areas overlap political constituencies and administrative jurisdictions, result in transparent governance and accountable urban management.

Principle six: human scale

Intelligent urbanism encourages ground level, pedestrian oriented urban patterns, based on anthropometric dimensions. Walkable, mixed use urban villages are encouraged over single-function blocks, linked by motor ways, and surrounded by parking lots

An abiding axiom of urban planning, urban design and city planning has been the promotion of people friendly places, pedestrian walkways and public domains where people can meet freely. These can be parks, gardens, glass-covered gallerias, arcades, courtyards, street side cafes, river- and hill-side stroll ways, and a variety of semi-covered spaces. 

Intelligent urbanism promotes the scale of the pedestrian moving on the pathway, as opposed to the scale of the automobile on the expressway. Intelligent urbanism promotes the ground plan of imaginable precincts, as opposed to the imagery of façades and the monumentality of the section. It promotes the personal visibility of places moving on foot at eye level. 

Intelligent urbanism advocates removing artificial barrier and promotes face-to-face contact. Proponents argue that the automobile, single use zoning and the construction of public structures in isolated compounds, all deteriorate the human condition and the human scale of the city. 

According to PIU proponents, the trend towards urban sprawl can be overcome by developing pedestrian circulation networks along streets and open spaces that link local destinations. Shops, amenities, day care, vegetable markets and basic social services should be clustered around public transport stops, and at a walkable distance from work places, public institutions, high and medium density residential areas. Public spaces should be integrated into residential, work, entertainment and commercial areas. Social activities and public buildings should orient onto public open spaces. These should be the interchange sites for people on the move, where they can also revert into the realm of “slowness," of community life and of human interaction. 

Human scale can be achieved through building masses that “step down" to human scale open spaces; by using arcades and pavilions as buffers to large masses; by intermixing open spaces and built masses sensitively; by using anthropometric proportions and natural materials. Traditional building precedents often carry within them a human scale language, from which a contemporary fabric of build may evolve. 

The focus of intelligent urbanism is the ground plane, pedestrian movement and interaction along movement channels, stems, at crossing nodes, at interactive hubs and within vibrant urban cores. The PIU holds many values in common with Transit Oriented Development, but the PIU goal is not merely to replace the automobile, nor to balance it. These are mundane requirements of planning, which the PIU assumes are found in every design and urban configuration. The PIU goal is to enrich the human condition and to enhance the realm of human possibilities. 

Intelligent urbanism conceives of urbanity as a process of facilitating human behavior toward more tolerant, more peaceful, more accommodating and more sensitive modalities of interaction and conflict resolution. Intelligent urbanism recognizes that ‘urbanity’ emerges where people mix and interact on a face-to-face basis, on the ground, at high densities and amongst diverse social and economic groups. Intelligent urbanism nurtures ‘urbanity’ through designs and plans that foster human scale interaction.

Principle seven: opportunity matrix

The PIU envisions the city as a vehicle for personal, social, and [economic development], through access to a range of organizations, services, facilities and information providing a variety of opportunities for enhanced employment, economic engagement, education, and recreation. This principle aims to increase access to shelter, health care and human resources development. It aims to increase safety and hygienic conditions. The city is a place of economic opportunity. This is generally said with regard to urban annual net product, enriched urban economic base, sustained employment generation and urban balance of trade. More significantly this is true for the individuals who settle in cities. Moreover, cities are places where individuals can increase their knowledge, skills and sensitivities. Cities provide access to health care and preventive medicine. They provide a great umbrella of services under which the individual can leave aside the struggle for survival, and get on with the finer things of life.

The PIU sees cities as catalysts for personal definition and self-discovery. In cities people get inspired, build a drive to achieve, discover aspects of their personalities, skills and intellectual curiosity which they use to craft their identity.

The city provides a range of services and facilities, whose realization in villages are the all-consuming struggle of rural inhabitants. Potable water; sewerage management; energy for cooking, heat and lighting are all piped and wired in; solid waste disposal and storm water drainage are taken for granted. The city offers access through roads, public transit, telephones and the Internet. The peace and security provided by effective policing systems, and the courts of law, are just assumed to be there in the city. Then there are the schools, the recreation facilities, the health services and a myriad of professional services offered in the city market place.

Intelligent urbanism views the city as an opportunity system. Yet these opportunities are not equally distributed. Security, health care, education, shelter, hygiene, and most of all employment, are not equally accessible. Proponents of intelligent urbanism see the city as playing an equalizing role allowing citizens to grow according to their own essential capabilities and efforts. If the city is an institution, which generates opportunities, intelligent urbanism promotes the concept of equal access to opportunities within the urban system. 

Intelligent urbanism promotes a guaranteed access to education, health care, police protection, and justice before the law, potable water, and a range of basic services. Perhaps this principle, more than any other, distinguishes intelligent urbanism from other elitist, efficiency oriented urban charters and regimes. 

Intelligent urbanism does not say every household will stay in an equivalent house, or travel in the same vehicle, or consume the same amount of electricity. 

Intelligent urbanism recognizes the existence of poverty, of ignorance, of ill health, of malnutrition, of low skills, of gender bias and ignorance of the urban system itself. Intelligent urbanism is courageous in confronting these forms of inequality, and backlogs in social and economic development. Intelligent urbanism sees an urban plan, not only as a physical plan, but also as a social plan and as an economic plan. 

The ramifications of this understanding are that the people living in intelligent cities should not experience urban development in “standard doses". In short, people may be born equal or unequal, but they grow inequitably. An important role of the city is to provide a variety of paths and channels for each individual to set right their own future, against the inequity of their past, or the special challenges they face. According to proponents of this principle this is the most salient aspect of a free society; than even voting rights access to opportunity is the essence of self-liberation and human development (Sen:2000). 

According to proponents of intelligent urbanism, there will be a variety of problems faced by urbanites and they need a variety of opportunity channels for resolution. If there are ten problem areas where people are facing stresses, like economic engagement, health, shelter, food, education, recreation, transport, etc., there must be a variety of opportunities through which individuals and households can resolve each of these stresses. There must be ten channels to resolve each of ten stresses! If this opportunity matrix is understood and responded to, the city is truly functioning as an opportunity matrix. For example, opportunities for shelter could be through the channels of lodges, rented rooms, studio apartments, bedroom apartments and houses. It could be through the channels of ownership, through a variety of tendencies. It could be through opportunities for self-help, or incremental housing. It could be through the up-gradation of slums. Intelligent urbanism promotes a wide range of solutions, where any stress is felt. It therefore promotes a range of problem statements, options, and variable solutions to urban stresses. 

Intelligent urbanism sees cities as processes. Proponents argue that good urban plans facilitate those processes and do not place barriers before them. For example, it does not judge a “slum" as a blight on society; it sees the possibility that such a settlement may be an opportunity channel for entry into the city. Such a settlement may be the only affordable shelter, within easy access to employment and education, for a new immigrant household in the city. According to intelligent urbanism, if the plan ignores, or destroys such settlements, it is creating a city of barriers and despair wherein a poor family, offering a good service to the city, is denied a modicum of basic needs for survival. Alternatively, if the urban plan recognizes that the “slum" is a mechanism for self development, a spring-board from which children have access to education, a place which can be up-graded with potable water, basic sanitary facilities, street lights and paving…then it is a plan for opportunity. Intelligent urbanism believes that there are slums of hope and slums of despair. It promotes slums of hope, which contribute, not only to individual opportunities, but also to nation building

The opportunity matrix must also respond to young professionals, to skilled, well-paid day laborers, to the upper middle class and to affluent entrepreneurs. If a range of needs, of abilities to pay, of locational requirements, and of levels of development of shelter, is addressed, then opportunities are being created. 

Intelligent urbanism believes that private enterprise is the logical provider of opportunities, but that alone it will not be just or effective. The regime of land, left to market forces alone, will create an exclusive, dysfunctional society. Intelligent urbanism believes that there is an essential role for the civil society to intervene in the opportunity matrix of the city. 

Intelligent urbanism promotes opportunities through access to:
  • Basic and primary education, skill development and knowledge about the urban world;
  • Basic health care, potable water, solid waste disposal and hygiene;
  • Urban facilities like storm drainage, street lights, roads and footpaths;
  • Recreation and entertainment;
  • Transport, energy, communications;
  • Public participation and debate;
  • Finance and investment mechanisms;
  • Land and/or built-up space where goods and services can be produced;
  • Rudimentary economic infrastructure;
  • Intelligent urbanism provides a wide range of zones, districts and precincts where activities and functions can occur without detracting from one another.
Intelligent urbanism proposes that enterprise can only flourish where a public framework provides opportunities for enterprise. This system of opportunities operates through public investments in economic and social infrastructure; through incentives in the form of appropriate finance, tax inducements, subsidized skill development for workers, and: regulations which protect the environment, safety, hygiene and health. To ensure a stable playing field where one can make an investment with predictable returns, a modicum of regulation is necessary. Proponents argue that it is through government regulations that private investment can be protected from fraud. It is through government regulation that the under-pinning conditions for free enterprise can be protected.

Principle eight: regional integration

Intelligent urbanism envisions the city as an organic part of a larger environmental, socio-economic and cultural-geographic system, essential for its sustainability. This zone of influence is the region. Likewise, it sees the region as integrally connected to the city. Intelligent urbanism sees the planning of the city and its hinterland as a single holistic process. Proponents argue if one does not recognize growth as a regional phenomenon, then development will play a hopscotch game of moving just a bit further along an arterial roads, further up valleys above the municipal jurisdiction, staying beyond the path of the city boundary, development regulations and of the urban tax regime. 

The region may be defined as the catchment area from which employees and students commute into the city on a daily basis. It is the catchment area from which people choose to visit one city, as opposed to another, for retail shopping and entertainment. Economically the city region may include the hinterland that depends on its wholesale markets, banking facilities, transport hubs and information exchanges. The region needing integration may be seen as the zone from which perishable foods, firewood and building materials supply the city. The economic region can also be defined as the area managed by exchanges in the city. Telephone calls to the region go through the city's telecom exchange; post goes through the city's general post office; money transfers go through the city’s financial institutions and internet data passes electronically through the city’s servers. The area over which “city exchanges" disperse matter can well be called the city’s economic hinterland or region. Usually the region includes dormitory communities, airports, water reservoirs, perishable food farms, hydro facilities, out-of-doors recreation and other infrastructure that serves the city. Intelligent urbanism sees the integrated planning of these services and facilities as part of the city planning process. 

Intelligent urbanism understands that the social and economic region linked to a city also has a physical form, or a geographic character. A hierarchy of watersheds, creating valleys and defining edges of neighborhoods, may define the geographic character. Forest ranges, fauna and avifauna habitats are set within such regions and are connected by natural corridors for movement and cross-fertilization. Within this larger, environmental scenario, one must conceptualize urbanism in terms of watersheds, subterranean aquifer systems, and other natural systems that operate across the entire region. Economic infrastructure, such as roads, hydro basins, irrigation channels, water reservoirs and related distribution networks usually follow the terrain of the regional geography. The region’s geographic portals, and lines of control, may also define defense and security systems deployment. 

Intelligent urbanism recognizes that there is always a spillover of population from the city into the region, and that population in the region moves into the city for work, shopping, entertainment, health care and education. With thoughtful planning the region can take pressure off of the city. Traditional and new settlements within the urban region can be enhanced and densified to accommodate additional urban households. There are many activities within the city, which are growing and are incompatible with urban habitat. Large, noisy and polluting workshops and manufacturing units are amongst these. Large wholesale markets, storage sheds, vehicular maintenance garages, and waste management facilities need to be housed outside of the city’s limits in their own satellite enclaves. In larger urban agglomerations a number of towns and cities are clustered around a major urban center forming a metropolitan region.

Intelligent urbanism is not just planning for the present; it is also planning for the distant future. Intelligent urbanism is not Utopian, but futuristic in its need to forecast the scenarios to come, within its own boundaries, and within the boundaries of the distant future.

Principle nine: balanced movement

Intelligent urbanism advocates integrated transport systems comprising walkways, cycle paths, bus lanes, light rail corridors, under-ground metros and automobile channels. A balance between appropriate modes of movement is proposed. More capital intensive transport systems should move between high density nodes and hubs, which interchange with lower technology movement options. These modal split nodes become the public domains around which cluster high density, pedestrian, mixed-use urban villages (Taniguchi:2001). 

The PIU accepts that the automobile is here to stay, but that it should not be made essential by design. A well planned metropolis would densify along mass transit corridors and around major urban hubs. Smaller, yet dense, urban nodes are seen as micro-zones of medium level density, public amenities and pedestrian access. At these points lower level nodal split will occur, such as between bus loops and cycle tracts. The PIU views nodal split points as places of urban conviviality and access to services and facilities. Modal split can be between walking, cycling, driving, and mass transit. Bus loops may feed larger rail-based rapid-movement corridors. Social and economic infrastructure becomes more intensive as movement corridors become more intense.

Principle ten: institutional integrity

Intelligent urbanism holds that good practices inherent in considered principles can only be realized through accountable, transparent, competent and participatory local governance, founded on appropriate data bases, due entitlements, civic responsibilities and duties. The PIU promotes a range of facilitative and promotive urban development management tools to achieve appropriate urban practices, systems and forms(Islam:2000). None of the principles or practices the PIU promotes can be implemented unless there is a strong and rational institutional framework to define, channel and legalize urban development, in all of its aspects. Intelligent urbanism envisions the institutional framework as being very clear about the rules and regulations it sponsors and that those using discretion in implementing these measures must do so in a totally open, recorded and transparent manner. 

Intelligent urbanism facilitates the public in carrying out their honest objectives. It does not regulate and control the public. It attempts to reduce the requirements, steps and documentation required for citizens to process their proposals. 

Intelligent urbanism is also promotive in furthering the interests of the public in their genuine utilization of opportunities. It promotes site and services schemes for households who can construct their own houses. It promotes up-gradation of settlements with inadequate basic services. It promotes innovative financing to a range of actors who can contribute to the city’s development. Intelligent urbanism promotes a limited role for government, for example in “packaging" large-scale urban development schemes, so that the private sector is promoted to actually build and market urban projects, which were previously built by the government. 

Intelligent urbanism does not consider itself naïve. It recognizes that there are developers and promoters who have no long term commitment to their own constructions, and their only concern is to hand over a dwelling, gain their profit and move on. For these players it is essential to have Development Control Regulations, which assure the public that the products they invest in are safe, hygienic, orderly, durable and efficient. For the discerning citizen, such rules also lay out the civil understanding by which a complex society agrees to live together. 

The PIU contends that there must be a cadastral System wherein all of the land in the jurisdiction of cities is demarcated, surveyed, characterized and archived, registering its legal owner, its legal uses, and the tax defaults against it. 

The institutional framework can only operate where there is a Structure Plan, or other document that defines how the land will be used, serviced, and accessed. The Structure Plan tells landowners and promoters what the parameters of development are, which assures that their immediate investments are secure, and that the returns and use of such efforts are predictable. A Structure Plan is intended to provide owners and investors with predictable future scenarios. Cities require efficient patterns for their main infrastructure systems and utilities. According to PIU proponents, land needs to be used in a judicious manner, organizing complementary functions and activities into compact, mixed use precincts and separating out non-compatible uses into their own precincts. In a similar manner, proponents argue it is only through a plan that heritage sites and the environment can be legally protected. Public assets in the form of nature, religious places, heritage sites and open space systems must be designated in a legal plan. 

Intelligent urbanism proposes that the city and its surrounding region be regulated by a Structure Plan, or equivalent mechanism, which acts as a legal instrument to guide the growth, development and enhancement of the city. 

According to proponents, there must be a system of participation by the “Stake Holders" in the preparation of plans. Public meetings, hearings of objections and transparent processes of addressing objections, must be institutionalized. Intelligent urbanism promotes Public Participation. Local Area Plans must be prepared which address local issues and take into account local views and sentiments regarding plan objectives, configurations, standards and patterns. Such plans lay out the sites of plots showing the roads, public open spaces, amenities areas and conservation sites. Land Pooling assures the beneficiaries from provision of public infrastructure and amenities proportionally contribute and that a few individuals do not suffer from reservations in the plan. 

According to proponents, there must be a system of Floor Area Ratios to assure that the land and the services are not over pressured. No single plot owner should have more than the determined "fair share" of utilization of the access roads, amenities and utilities that service all of the sites. Floor Area Ratios temper this relationship as regulated the manner in which public services are consumed. According to PIU proponents, Transfer of Development Rights benefits land owners whose properties have been reserved under the plan. It also benefits the local authorities that lack the financial resources to purchase lands to implement the Structure Plans. It benefits concentrated, city center project promoters who have to amortize expensive land purchases, by allowing them to purchase the development rights from the owners of reserved lands and to hand over those properties to the plan implementing authority. This allows the local authority to widen roads and to implement the Structure Plan. The local authority then transfers the needed development right to city center promoters. 

Intelligent urbanism supports the use of Architectural Guidelines where there is a tradition to preserve and where precedents can be used to specify architectural elements, motifs and language in a manner, which intended to reinforce a cultural tradition. Building designs must respect traditional elements, even though the components may vary greatly to integrate contemporary functions. Even in a greenfield setting Architectural Guidelines are required to assure harmony and continuity of building proportions, scale, color, patterns, motifs, materials and facades. 

Intelligent urbanism insists on safety, hygiene, durability and utility in the design and construction of buildings. Where large numbers of people gather in schools, hospitals, and other public facilities that may become emergency shelters in disasters, special care must be exercised. A suitable Building Code is the proposed instrument to achieve these aims. 

PIU proponents state that those who design buildings must be professionally qualified architects; those who design the structures (especially of more than ground plus two levels) must be professionally qualified structural engineers; those who build buildings must be qualified civil engineers; and, those who supervise and control construction must be qualified construction managers. Intelligent urbanism promotes the professionalisation of the city making process. While promoting professionalism, intelligent urbanism proposes that this not become a barrier in the development process. Small structures, low-rise structures, and humble structures that do not house many people can be self designed and constructed by the inhabitants themselves. Proponents maintain that there must be recognized Professional Accrediting Boards, or Professional Bodies, to see that urban development employs adequate technical competence. 

Finally, there must be legislation creating statutory local authorities, and empowering them to act, manage, invest, service, protect, promote and facilitate urban development and all of the opportunities that a modern city must sponsor. 

Intelligent urbanism insists that cities, local authorities, regional development commissions and planning agencies be professionally managed. City Managers can be hired to manage the delivery of services, the planning and management of planned development, the maintenance of utilities and the creation of amenities. 

Intelligent urbanism views plans and urban designs and housing configurations as expressions of the people for whom they are planned. The processes of planning must therefore be a participatory involving a range of stakeholders. The process must be a transparent one, which makes those privileged to act as guardians of the people’s will accountable for their decisions and choices. Intelligent urbanism sees urban planning and city governance as the most salient expressions of civility. Intelligent urbanism fosters the evolution of institutional systems that enhance transparency, accountability and rational public decision making.

Movements implementing the ten principles

Though not necessarily related to the principles of intelligent urbanism, there are examples representing all or some of them in urban design theory and practice. Concurrently, the recent movements of New Urbanism and New Classical Architecture promote a sustainable approach towards construction, that appreciates and develops smart growth, architectural tradition and classical design. This in contrast to modernist and globally uniform architecture, as well as leaning against solitary housing estates and suburban sprawl. Both trends started in the 1980s. The Driehaus Architecture Prize is an award that recognizes efforts in New Urbanism and New Classical Architecture, and is endowed with a prize money twice as high as that of the modernist Pritzker Prize.

Sustainable design

From Wikipedia, the free encyclopedia

Environmentally sustainable design (also called environmentally conscious design, eco design etc.) is the philosophy of designing physical objects, the built environment, and services to comply with the principles of ecological sustainability.

Note: Social and economic factors are vitally important considerations, but are sub systems in the larger context of the Earth's eco-sphere.

Theory

The intention of sustainable design is to "eliminate negative environmental impact completely through skillful, sensitive design". Manifestations of sustainable design require renewable resources, impact the environment minimally, and connect people with the natural environment.

“Human beings don't have a pollution problem; they have a design problem. If humans were to devise products, tools, furniture, homes, factories, and cities more intelligently from the start, they wouldn't even need to think in terms of waste, or contamination, or scarcity. Good design would allow for abundance, endless reuse, and pleasure.” - The Upcycle by authors Michael Braungart and William McDonough, 2013. 

Design-related decisions are happening everywhere on a daily basis, impacting “sustainable development” or provisioning for the needs of future generations of life on earth. Sustainability and design are intimately linked. Quite simply, our future is designed. The term “design” is here used to refer to practices applied to the making of products, services, as well as business and innovation strategy — all of which inform sustainability. Sustainability can be thought of as the property of continuance; that is, what is sustainable can be continued into the future. 

Conceptual problems

Diminishing returns

The principle that all directions of progress run out, ending with diminishing returns, is evident in the typical 'S' curve of the technology life cycle and in the useful life of any system as discussed in industrial ecology and life cycle assessment. Diminishing returns are the result of reaching natural limits. Common business management practice is to read diminishing returns in any direction of effort as an indication of diminishing opportunity, the potential for accelerating decline and a signal to seek new opportunities elsewhere.

Unsustainable investment

A problem arises when the limits of a resource are hard to see, so increasing investment in response to diminishing returns may seem profitable as in the Tragedy of the Commons, but may lead to a collapse. This problem of increasing investment in diminishing resources has also been studied in relation to the causes of civilization collapse by Joseph Tainter among others. This natural error in investment policy contributed to the collapse of both the Roman and Mayan, among others. Relieving over-stressed resources requires reducing pressure on them, not continually increasing it whether more efficiently or not.

Waste prevention

Plans for Floriade 2012 in Venlo, the Netherlands: "The Greenest Building in the Netherlands - no external fuel, electricity, water or sewage."
 
Negative Effects of Waste

About 80 million tonnes of waste in total are generated in the U.K. alone, for example, each year. And with reference to only household waste, between 1991/92 and 2007/08, each person in England generated an average of 1.35 pounds of waste per day.

Experience has now shown that there is no completely safe method of waste disposal. All forms of disposal have negative impacts on the environment, public health, and local economies. Landfills have contaminated drinking water. Garbage burned in incinerators has poisoned air, soil, and water. The majority of water treatment systems change the local ecology. Attempts to control or manage wastes after they are produced fail to eliminate environmental impacts.

The toxics components of household products pose serious health risks and aggravate the trash problem. In the U.S., about eight pounds in every ton of household garbage contains toxic materials, such as heavy metals like nickel, lead, cadmium, and mercury from batteries, and organic compounds found in pesticides and consumer products, such as air freshener sprays, nail polish, cleaners, and other products. When burned or buried, toxic materials also pose a serious threat to public health and the environment.

The only way to avoid environmental harm from waste is to prevent its generation. Pollution prevention means changing the way activities are conducted and eliminating the source of the problem. It does not mean doing without, but doing differently. For example, preventing waste pollution from litter caused by disposable beverage containers does not mean doing without beverages; it just means using refillable bottles. 

Waste prevention strategies In planning for facilities, a comprehensive design strategy is needed for preventing generation of solid waste. A good garbage prevention strategy would require that everything brought into a facility be recycled for reuse or recycled back into the environment through biodegradation. This would mean a greater reliance on natural materials or products that are compatible with the environment. 

Any resource-related development is going to have two basic sources of solid waste — materials purchased and used by the facility and those brought into the facility by visitors. The following waste prevention strategies apply to both, although different approaches will be needed for implementation:
  • use products that minimize waste and are nontoxic
  • compost or anaerobically digest biodegradable wastes
  • reuse materials onsite or collect suitable materials for offsite recycling
  • consuming less resources means creating less waste, therefore it reduces the impact on the environment.

Climate change

Perhaps the most obvious and overshadowing driver of environmentally conscious sustainable design can be attributed to global warming and climate change. The sense of urgency that now prevails for humanity to take actions against climate change has increased manifold in the past thirty years. Climate change can be attributed to several faults; and improper design that doesn't take into consideration the environment is one of them. While several steps in the field of sustainability have begun, most products, industries and buildings still consume a lot of energy and create a lot of pollution.

Loss of Biodiversity

Unsustainable environment design, or simply design, also affects the biodiversity of a region. Improper design of transport highways force thousands of animals to move further into forest boundaries. Poorly designed hydrothermal dams affect the mating cycle and indirectly, the numbers of local fish.

Sustainable design principles

The California Academy of Sciences, San Francisco, California, is a sustainable building designed by Renzo Piano. It opened on September 27, 2008
 

While the practical application varies among disciplines , some common principles are as follows:
  • Low-impact materials: choose non-toxic, sustainably produced or recycled materials which require little energy to process
  • Energy efficiency: use manufacturing processes and produce products which require less energy
  • Emotionally durable design: reducing consumption and waste of resources by increasing the durability of relationships between people and products, through design
  • Design for reuse and recycling: "Products, processes, and systems should be designed for performance in a commercial 'afterlife'."
  • Targeted durability, not immortality, should be a design goal.
  • Material diversity in multicomponent products should be minimized to promote disassembly and value retention.
  • Design impact measures for total carbon footprint and life-cycle assessment for any resource used are increasingly required and available. Many are complex, but some give quick and accurate whole-earth estimates of impacts. One measure estimates any spending as consuming an average economic share of global energy use of 8,000 BTU (8,400 kJ) per dollar and producing CO2 at the average rate of 0.57 kg of CO2 per dollar (1995 dollars US) from DOE figures.
  • Sustainable design standards and project design guides are also increasingly available and are vigorously being developed by a wide array of private organizations and individuals. There is also a large body of new methods emerging from the rapid development of what has become known as 'sustainability science' promoted by a wide variety of educational and governmental institutions.
  • Biomimicry: "redesigning industrial systems on biological lines ... enabling the constant reuse of materials in continuous closed cycles..."
  • Service substitution: shifting the mode of consumption from personal ownership of products to provision of services which provide similar functions, e.g., from a private automobile to a carsharing service. Such a system promotes minimal resource use per unit of consumption (e.g., per trip driven).
  • Renewable resource: materials should come from nearby (local or bioregional), sustainably managed renewable sources that can be composted when their usefulness has been exhausted.
  • Robust eco-design: robust design principles are applied to the design of a pollution sources.

Bill of Rights for the Planet

A model of the new design principles necessary for sustainability is exemplified by the "Bill of Rights for the Planet" or "Hannover Principles" - developed by William McDonough Architects for EXPO 2000 that was held in Hannover, Germany.
The Bill of Rights:
  1. Insist on the right of humanity and nature to co-exist in a healthy, supportive, diverse, and sustainable conditions.
  2. Recognize Interdependence. The elements of human design interact with and depend on the natural world, with broad and diverse implications at every scale. Expand design considerations to recognizing even distant effects.
  3. Respect relationships between spirit and matter. Consider all aspects of human settlement including community, dwelling, industry, and trade in terms of existing and evolving connections between spiritual and material consciousness.
  4. Accept responsibility for the consequences of design decisions upon human well-being, the viability of natural systems, and their right to co-exist.
  5. Create safe objects of long-term value. Do not burden future generations with requirements for maintenance or vigilant administration of potential danger due to the careless creations of products, processes, or standards.
  6. Eliminate the concept of waste. Evaluate and optimize the full life-cycle of products and processes, to approach the state of natural systems in which there is no waste.
  7. Rely on natural energy flows. Human designs should, like the living world, derive their creative forces from perpetual solar income. Incorporating this energy efficiently and safely for responsible use.
  8. Understand the limitations of design. No human creation lasts forever and design does not solve all problems. Those who create and plan should practice humility in the face of nature. Treat nature as a model and mentor, not an inconvenience to be evaded or controlled.
  9. Seek constant improvement by the sharing of knowledge. Encourage direct and open communication between colleagues, patrons, manufacturers and users to link long term sustainable considerations with ethical responsibility, and re-establish the integral relationship between natural processes and human activity.
These principles were adopted by the World Congress of the International Union of Architects (UIA) in June 1993 at the American Institute of Architects' (AIA) Expo 93 in Chicago. Further, the AIA and UIA signed a "Declaration of Interdependence for a Sustainable Future." In summary, the declaration states that today's society is degrading its environment and that the AIA, UIA, and their members are committed to:
  • Placing environmental and social sustainability at the core of practices and professional responsibilities
  • Developing and continually improving practices, procedures, products, services, and standards for sustainable design
  • Educating the building industry, clients, and the general public about the importance of sustainable design
  • Working to change policies, regulations, and standards in government and business so that sustainable design will become the fully supported standard practice
  • Bringing the existing built environment up to sustainable design standards.
In addition, the Interprofessional Council on Environmental Design (ICED), a coalition of architectural, landscape architectural, and engineering organizations, developed a vision statement in an attempt to foster a team approach to sustainable design. ICED states: The ethics, education and practices of our professions will be directed to shape a sustainable future. . . . To achieve this vision we will join . . . as a multidisciplinary partnership." 

These activities are an indication that the concept of sustainable design is being supported on a global and interprofessional scale and that the ultimate goal is to become more environmentally responsive. The world needs facilities that are more energy efficient and that promote conservation and recycling of natural and economic resources.

Economic and Social Sustainable Design

Environmentally sustainable design is most beneficial when it works hand in hand with the other two counterparts of sustainable design – the economic and socially sustainable designs. These three terms are often coined under the title ‘triple bottom line.’ It is imperative that we think about value in not solely economic or financial terms, but also in relation to natural capital (the biosphere and earth's resources), social capital (the norms and networks that enable collective action), and human capital (the sum total of knowledge, experience, intellectual property, and labor available to society). The purely economic capital so many people and organizations strive for, and make decisions by, are often not conducive to these alternative forms of capital. For sustainable design, there is a need to reset how we, as inhabitants of the earth, think about value. In some countries the term sustainable design is known as ecodesign, green design or environmental design. Victor Papanek, embraced social design and social quality and ecological quality, but did not explicitly combine these areas of design concern in one term. Sustainable design and design for sustainability are more common terms, including the triple bottom line (people, planet and profit).

In the EU, the concept of sustainable design is referred to as ecodesign. Little discussions have however taken place over the importance of this concept in the run-up to the circular economy package, that the European Commission will be tabling by the end of 2015. To this effect, an Ecothis.EU campaign was launched to raise awareness about the economic and environmental consequences of not including eco-design as part of the circular economy package.

Aspects of environmentally sustainable design

Emotionally durable design

According to Jonathan Chapman of Carnegie Mellon University, USA, emotionally durable design reduces the consumption and waste of natural resources by increasing the resilience of relationships established between consumers and products." Essentially, product replacement is delayed by strong emotional ties. In his book, Emotionally Durable Design: Objects, Experiences & Empathy, Chapman describes how "the process of consumption is, and has always been, motivated by complex emotional drivers, and is about far more than just the mindless purchasing of newer and shinier things; it is a journey towards the ideal or desired self, that through cyclical loops of desire and disappointment, becomes a seemingly endless process of serial destruction". Therefore, a product requires an attribute, or number of attributes, which extend beyond utilitarianism.

According to Chapman, 'emotional durability' can be achieved through consideration of the following five elements:
  • Narrative: How users share a unique personal history with the product.
  • Consciousness: How the product is perceived as autonomous and in possession of its own free will.
  • Attachment: Can a user be made to feel a strong emotional connection to a product?
  • Fiction: The product inspires interactions and connections beyond just the physical relationship.
  • Surface: How the product ages and develops character through time and use.
As a strategic approach, "emotionally durable design provides a useful language to describe the contemporary relevance of designing responsible, well made, tactile products which the user can get to know and assign value to in the long-term." According to Hazel Clark and David Brody of Parsons The New School for Design in New York, “emotionally durable design is a call for professionals and students alike to prioritise the relationships between design and its users, as a way of developing more sustainable attitudes to, and in, design things.”

Beauty and sustainable design

Because standards of sustainable design appear to emphasize ethics over aesthetics, some designers and critics have complained that it lacks inspiration. Pritzker Architecture Prize winner Frank Gehry has called green building "bogus," and National Design Awards winner Peter Eisenman has dismissed it as "having nothing to do with architecture." In 2009, The American Prospect asked whether "well-designed green architecture" is an "oxymoron."

Others claim that such criticism of sustainable design is misguided. A leading advocate for this alternative view is architect Lance Hosey, whose book The Shape of Green: Aesthetics, Ecology, and Design (2012) was the first dedicated to the relationships between sustainability and beauty. Hosey argues not just that sustainable design needs to be aesthetically appealing in order to be successful, but also that following the principles of sustainability to their logical conclusion requires reimagining the shape of everything designed, creating things of even greater beauty. Reviewers have suggested that the ideas in The Shape of Green could "revolutionize what it means to be sustainable." Small and large buildings are beginning to successfully incorporate principles of sustainability into award-winning designs. Examples include One Central Park and the Science Faculty building, UTS. The popular Living Building Challenge has incorporated beauty as one of its petals in building design. Sustainable products and processes are required to be beautiful because it allows for emotional durability. Many people also argue that biophilia is innately beautiful. Which is why building architecture is designed such that people feel close to nature and is often surrounded by well-kept lawns – a design that is both ‘beautiful’ and encourages the inculcation of nature in our daily lives. Or utilizes daylight design into the system – reducing lighting loads while also fulfilling our need for being close to that which is outdoors.

Economic Aspects

Discussed above, economics is another aspect of it environmental design that is crucial to most design decisions. It is obvious that most people consider the cost of any design before they consider the environmental impacts of it. Therefore, there is a growing nuance of pitching ideas and suggestions for environmentally sustainable design by highlighting the economical profits that they bring to us. "As the green design field matures, it becomes ever more clear that integration is the key to achieving energy and environmental goals especially if cost is a major driver." Building Green Inc. (1999) To achieve the more ambitious goals of the green design movement, architects, engineers and designers need to further embrace and communicate the profit and economic potential of sustainable design measures. Focus should be on honing skills in communicating the economic and profit potential of smart design, with the same rigor that have been applied to advancing technical building solutions.

Standards of Evaluation

There are several standards and rating systems developed as sustainability gains popularity. The list is endless, with most rating systems revolving around buildings and energy, and some covering products as well. Most rating systems certify on the basis of design as well as post construction or manufacturing.
While designing for environmental sustainability, it is imperative that the appropriate units are paid attention to. Often, different standards weigh things in different units, and that can make a huge impact on the outcome of the project. Another important aspect of using standards and looking at data involves understanding the baseline. A poor design baseline with huge improvements often show a higher efficiency percentage, while an intelligent baseline from the start might only have a little improvement needed and show lesser change. Therefore, all data should ideally be compared on similar levels, and also be looked at from multiple unit values.

LCA and Product Life

Life cycle assessment is the complete assessment of materials from their extraction, transport, processing, refining, manufacturing, maintenance, use, disposal, reuse and recycle stages. It helps put into perspective whether a design is actually environmentally sustainable in the long run. Products such as aluminum which can be reused multiple number of times but have a very energy intensive mining and refining which makes it unfavorable. Information such as this is done using LCA and then taken into consideration when designing.

Applications

Applications of this philosophy range from the microcosm — small objects for everyday use, through to the macrocosm — buildings, cities, and the Earth's physical surface. It is a philosophy that can be applied in the fields of architecture, landscape architecture, urban design, urban planning, engineering, graphic design, industrial design, interior design, fashion design and human-computer interaction

Sustainable design is mostly a general reaction to global environmental crises, the rapid growth of economic activity and human population, depletion of natural resources, damage to ecosystems, and loss of biodiversity. In 2013, eco architecture writer Bridgette Meinhold surveyed emergency and long-term sustainable housing projects that were developed in response to these crises in her book, “Urgent Architecture: 40 Sustainable Housing Solutions for a Changing World.” Featured projects focus on green building, sustainable design, eco-friendly materials, affordability, material reuse, and humanitarian relief. Construction methods and materials include repurposed shipping containers, straw bale construction, sandbag homes, and floating homes.

The limits of sustainable design are reducing. Whole earth impacts are beginning to be considered because growth in goods and services is consistently outpacing gains in efficiency. As a result, the net effect of sustainable design to date has been to simply improve the efficiency of rapidly increasing impacts. The present approach, which focuses on the efficiency of delivering individual goods and services, does not solve this problem. The basic dilemmas include: the increasing complexity of efficiency improvements; the difficulty of implementing new technologies in societies built around old ones; that physical impacts of delivering goods and services are not localized, but are distributed throughout the economies; and that the scale of resource use is growing and not stabilizing.

Sustainable architecture

Sustainable building design
 
Sustainable architecture is the design of sustainable buildings. Sustainable architecture attempts to reduce the collective environmental impacts during the production of building components, during the construction process, as well as during the lifecycle of the building (heating, electricity use, carpet cleaning etc.) This design practice emphasizes efficiency of heating and cooling systems; alternative energy sources such as solar hot water, appropriate building siting, reused or recycled building materials; on-site power generation - solar technology, ground source heat pumps, wind power; rainwater harvesting for gardening, washing and aquifer recharge; and on-site waste management such as green roofs that filter and control stormwater runoff. This requires close cooperation of the design team, the architects, the engineers, and the client at all project stages, from site selection, scheme formation, material selection and procurement, to project implementation. This is also called a charrette. Appropriate building siting and smaller building footprints are vital to an environmentally sustainable design. Oftentimes, a building may be very well designed, and energy efficient but its location requires people to travel far back and forth – increasing pollution that may not be building produced but is directly as a result of the building anyway. Sustainable architecture must also cover the building beyond its useful life. Its disposal or recycling aspects also come under the wing of sustainability. Often, modular buildings are better to take apart and less energy intensive to put together too. The waste from the demolition site must be disposed of correctly and everything that can be harvested and used again should be designed to be extricated from the structure with ease, preventing unnecessary wastage when decommissioning the building. Another important aspect of sustainable architecture stems from the question of whether a structure is needed. Sometimes the best that can be done to make a structure sustainable is retrofitting or upgrading the building services and supplies instead of tearing it down. Abu Dhabi, for example has undergone and is undergoing major retrofitting to slash its energy and water consumption rather than demolishing and rebuilding new structures.

Sustainable architects design with sustainable living in mind. Sustainable vs green design is the challenge that designs not only reflect healthy processes and uses but are powered by renewable energies and site specific resources. A test for sustainable design is — can the design function for its intended use without fossil fuel — unplugged. This challenge suggests architects and planners design solutions that can function without pollution rather than just reducing pollution. As technology progresses in architecture and design theories and as examples are built and tested, architects will soon be able to create not only passive, null-emission buildings, but rather be able to integrate the entire power system into the building design. In 2004 the 59 home housing community, the Solar Settlement, and a 60,000 sq ft (5,600 m2) integrated retail, commercial and residential building, the Sun Ship, were completed by architect Rolf Disch in Freiburg, Germany. The Solar Settlement is the first housing community worldwide in which every home, all 59, produce a positive energy balance.

An essential element of Sustainable Building Design is indoor environmental quality including air quality, illumination, thermal conditions, and acoustics. The integrated design of the indoor environment is essential and must be part of the integrated design of the entire structure. ASHRAE Guideline 10-2011 addresses the interactions among indoor environmental factors and goes beyond traditional standards.

Concurrently, the recent movements of New Urbanism and New Classical Architecture promote a sustainable approach towards construction, that appreciates and develops smart growth, architectural tradition and classical design. This in contrast to modernist and globally uniform architecture, as well as leaning against solitary housing estates and suburban sprawl. Both trends started in the 1980s. The Driehaus Architecture Prize is an award that recognizes efforts in New Urbanism and New Classical Architecture, and is endowed with a prize money twice as high as that of the modernist Pritzker Prize.

Green Design

Green design has often been used interchangeably with environmentally sustainable design. There is a popular debate about this with several arguing that green design is in effect narrower than sustainable design, which takes into account a larger system. Green design focuses on the short term goals and while it is a worthy goal, a larger impact is possible using sustainable design. Another factor to be considered is that green design has been stigmatized by popular personalities such as Pritzker Architecture Prize winner Frank Gehry, but this branding hasn't reached sustainable design. A large part of that is because of how environmentally sustainable design is generally used hand in hand with economically sustainable design and socially sustainable design. Finally, green design is although unintentionally, often associated only with architecture while sustainable design has been considered under a much larger scope.

Engineering Design

Sustainable engineering is the process of designing or operating systems such that they use energy and resources sustainably, in other words, at a rate that does not compromise the natural environment, or the ability of future generations to meet their own needs. Common engineering focuses revolve around water supply, production, sanitation, cleaning up of pollution and waste sites, restoring natural habitats etc.

Sustainable Interior Design

Achieving a healthy and aesthetic environment for the occupants of a space is one of the basic rules in the art of Interior design. When applying focus onto the sustainable aspects of the art, Interior Design can incorporate the study and involvement of functionality, accessibility, and aesthetics to environmentally friendly materials. The integrated design of the indoor environment is essential and must be part of the integrated design of the entire structure.
Goals of Sustainable Interior Design
Improving the overall building performance through the reduction of negative impacts on the environment is the primary goal. Reducing consumption of non-renewable resources, minimizing waste and creating healthy, productive environments are the primary objectives of sustainability. Optimizing site potential, minimizing non-renewable energy consumption, using environmentally preferable products, protecting and conserving water, enhancing indoor environmental quality, and optimizing operational and maintenance practices are some of the primary principles. An essential element of Sustainable Building Design is indoor environmental quality including air quality, illumination, thermal conditions, and acoustic. Interior design, when done correctly, can harness the true power of sustainable architecture.
Incorporating Sustainable Interior Design
Sustainable Interior Design can be incorporated through various techniques: water efficiency, energy efficiency, using non-toxic, sustainable or recycled materials, using manufactured processes and producing products with more energy efficiency, building longer lasting and better functioning products, designing reusable and recyclable products, following the sustainable design standards and guidelines, and more. For example, a room with large windows to allow for maximum sunlight should have neutral colored interiors to help bounce the light around and increase comfort levels while reducing light energy requirement. 

Interior Designers must take types of paints, adhesives, and more into consideration during their designing and manufacturing phase so they do not contribute to harmful environmental factors. Choosing whether to use a wood floor to marble tiled floor or carpeted floor can reduce energy consumption by the level of insulation that they provide. Utilizing materials that can withhold 24-hour health care facilities, such as linoleum, scrubbable cotton wall coverings, recycled carpeting, low toxic adhesive, and more.

Furthermore, incorporating sustainability can begin before the construction process begins. Purchasing items from sustainable local businesses, analyzing the longevity of a product, taking part in recycling by purchasing recycled materials, and more should be taken into consideration. Supporting local, sustainable businesses is the first step, as this not only increases the demand for sustainable products, but also reduces unsustainable methods. Traveling all over to find specific products or purchasing products from over seas contributes to carbon emissions in the atmosphere, pulling further away from the sustainable aspect. Once the products are found, it is important to check if the selection follows the Cradle-to-cradle design (C2C) method and they are also able to be reclaimed, recycled, and reused. Also paying close attention to energy-efficient products during this entire process contributes to the sustainability factors. The aesthetic of a space does not have to be sacrificed in order to achieve sustainable interior design. Every environment and space can incorporate materials and choices to reducing environmental impact, while still providing durability and functionality.
Promotion of Sustainable Interior Design
The mission to incorporate sustainable interior design into every aspect of life is slowly becoming a reality. The commercial Interior Design Association (IIDA) created the sustainability forum to encourage, support, and educate the design community and the public about sustainability. The Athena Sustainable Materials Institute ensures enabling smaller footprints by working with sustainability leaders in various ways in producing and consuming materials. Building Green considers themselves the most trusted voice for sustainable and healthy design, as they offer a variety of resources to dive deep into sustainability. Various acts, such as the Energy Policy Act (EPAct) of 2005 and the Energy Independence and Security Act (EISA) of 2007 have been revised and passed to achieve better efforts towards sustainable design. Federal efforts, such as the signing of a Memorandum of Understanding to the commitment of sustainable design and the Executive Order 13693 have also worked to achieve these concepts. Various guideline and standard documents have been published for the sake of sustainable interior design and companies like LEED (Leadership in Energy and Environmental Design) are guiding and certifying efforts put into motion to contribute to the mission. When the thought of incorporating sustainable design into an interior’s design is kept as a top goal for a designer, creating an overall healthy and environmentally friendly space can be achieved.

Global Examples of Sustainable Interior Design

  • Proximity Hotel in North Carolina, United States of America: The Proximity Hotel was the first hotel to be granted the LEED Platinum certification from the U.S. Green Building Council.
  • Shanghai Natural History Museum in Shanghai, China: This new museum incorporates evaporative cooling and maintained temperatures through is design and structure.
  • Vancouver Convention Centre West in Vancouver, British Columbia, Canada: The West location of the Vancouver Convention Centre was the first convention center in the world to be granted LEED Platinum.
  • Bullitt Center in Seattle, Washington, United States of America: Considered "The Greenest Commercial Building in the World," it is the first to achieve the Living Building Challenge certification.
  • Sydney, Australia became the first city in the country to contribute Green roof and Green wall to their architecture following their "Sustainable Sydney 2030" set of goals.

Sustainable urban planning

Sustainable design of cities is the task of designing and planning the outline of cities such that they have a low carbon footprint, have better air quality, rely on more sustainable sources of energy, and have a healthy relationship with the environment. Sustainable urban planning involves many disciplines, including architecture, engineering, biology, environmental science, materials science, law, transportation, technology, economic development, accounting and finance, and government, among others. This kind of planning also develops innovative and practical approaches to land use and its impact on natural resources. New sustainable solutions for urban planning problems can include green buildings and housing, mixed-use developments, walkability, greenways and open spaces, alternative energy sources such as solar and wind, and transportation options. Good sustainable land use planning helps improve the welfare of people and their communities, shaping their urban areas and neighborhoods into healthier, more efficient spaces. Design and planning of neighbourhoods are a major challenge when creating a favourable urban environment. The challenge is based on the principles of integrated approach to different demands: social, architectural, artistic, economic, sanitary and hygienic. Social demands are aimed at constructing network and placing buildings in order to create favourable conditions for their convenient use. Architectural-artistic solutions are aimed at single spatial composition of an area with the surrounding landscape. Economic demands include rational utilization of area territories. Sanitary and hygienic demands are of more interest in terms of creating sustainable urban areas.

Sustainable landscape and garden design

Sustainable landscape architecture is a category of sustainable design and energy-efficient landscaping concerned with the planning and design of outdoor space. Plants and materials may be bought from local growers to reduce energy used in transportation. Design techniques include planting trees to shade buildings from the sun or protect them from wind, using local materials, and on-site composting and chipping not only to reduce green waste hauling but to increase organic matter and therefore carbon in the soil

Some designers and gardeners such as Beth Chatto also use drought-resistant plants in arid areas (xeriscaping) and elsewhere so that water is not taken from local landscapes and habitats for irrigation. Water from building roofs may be collected in rain gardens so that the groundwater is recharged, instead of rainfall becoming surface runoff and increasing the risk of flooding

Areas of the garden and landscape can also be allowed to grow wild to encourage bio-diversity. Native animals may also be encouraged in many other ways: by plants which provide food such as nectar and pollen for insects, or roosting or nesting habitats such as trees, or habitats such as ponds for amphibians and aquatic insects. Pesticides, especially persistent pesticides, must be avoided to avoid killing wildlife. 

Soil fertility can be managed sustainably by the use of many layers of vegetation from trees to ground-cover plants and mulches to increase organic matter and therefore earthworms and mycorrhiza; nitrogen-fixing plants instead of synthetic nitrogen fertilizers; and sustainably harvested seaweed extract to replace micronutrients.

Sustainable landscapes and gardens can be productive as well as ornamental, growing food, firewood and craft materials from beautiful places. 

Sustainable landscape approaches and labels include organic farming and growing, permaculture, agroforestry, forest gardens, agroecology, vegan organic gardening, ecological gardening and climate-friendly gardening.

Sustainable agriculture

Sustainable agriculture adheres to three main goals:
  • Environmental Health,
  • Economic Profitability,
  • Social and Economic Equity.
A variety of philosophies, policies and practices have contributed to these goals. People in many different capacities, from farmers to consumers, have shared this vision and contributed to it. Despite the diversity of people and perspectives, the following themes commonly weave through definitions of sustainable agriculture. 

There are strenuous discussions — among others by the agricultural sector and authorities — if existing pesticide protocols and methods of soil conservation adequately protect topsoil and wildlife. Doubt has risen if these are sustainable, and if agrarian reforms would permit an efficient agriculture with fewer pesticides, therefore reducing the damage to the ecosystem.

Domestic machinery and furniture

Automobiles, home appliances and furnitures can be designed for repair and disassembly (for recycling), and constructed from recyclable materials such as steel, aluminum and glass, and renewable materials, such as Zelfo, wood and plastics from natural feedstocks. Careful selection of materials and manufacturing processes can often create products comparable in price and performance to non-sustainable products. Even mild design efforts can greatly increase the sustainable content of manufactured items.

Energy sector

Sustainable technology in the energy sector is based on utilizing renewable sources of energy such as solar, wind, hydro, bioenergy, geothermal, and hydrogen. Wind energy is the world's fastest growing energy source; it has been in use for centuries in Europe and more recently in the United States and other nations. Wind energy is captured through the use of wind turbines that generate and transfer electricity for utilities, homeowners and remote villages. Solar power can be harnessed through photovoltaics, concentrating solar, or solar hot water and is also a rapidly growing energy source. Advancements in the technology and modifications to photovoltaics cells provide a more in depth untouched method for creating and producing solar power. Researchers have found a potential way to use the photogalvanic effect to transform sunlight into electric energy. 

The availability, potential, and feasibility of primary renewable energy resources must be analyzed early in the planning process as part of a comprehensive energy plan. The plan must justify energy demand and supply and assess the actual costs and benefits to the local, regional, and global environments. Responsible energy use is fundamental to sustainable development and a sustainable future. Energy management must balance justifiable energy demand with appropriate energy supply. The process couples energy awareness, energy conservation, and energy efficiency with the use of primary renewable energy resources.

Design for sustainable manufacturing

Sustainable manufacturing can be defined as the creation of a manufactured product through a concurrent improvement in the resulting effect on factory and product sustainability. The concept of sustainable manufacturing demands a renewed design of production systems in order to condition the related sustainability on product life cycle and Factory operations.
  • Designing sustainable production systems imply, on the one hand, the analysis and optimization of intra-factory aspects that are related to manufacturing plants. Such aspects can regard the resource consumption restrain, the process efficiency, the ergonomics for the factory workers, the elimination of hazardous substances, the minimization of factory emissions and waste as well as internal emissions, the integrated management of information in the production facilities, and the technological updating of machines and plants.
  • Other inter-factories aspects concern the sustainable design of manufactured products, product chain dematerialisation, management of the background and foreground supply chains, support of circular economy paradigm, and the labelling for sustainability.
Advantageous reasons for why companies might chose to sustainably manufacture either their products or use a sustainable manufacturing process are:
  • Increase operational efficiency by reducing costs and waste
  • Respond to or reach new customers and increase competitive advantage
  • Protect and strengthen brand and reputation and build public trust
  • Build long-term business viability and success
  • Respond to regulatory constraints and opportunitiesThe Business Case for Sustainable Manufacturing

Water sector

Sustainable water technologies have become an important industry segment with several companies now providing important and scalable solutions to supply water in a sustainable manner. 

Beyond the use of certain technologies, Sustainable Design in Water Management also consists very importantly in correct implementation of concepts. Among one of these principal concepts is the fact normally in developed countries 100% of water destined for consumption, that is not necessarily for drinking purposes, is of potable water quality. This concept of differentiating qualities of water for different purposes has been called "fit-for-purpose". This more rational use of water achieves several economies, that are not only related to water itself, but also the consumption of energy, as to achieve water of drinking quality can be extremely energy intensive for several reasons.

Sustainable technologies

Sustainable technologies use less energy, fewer limited resources, do not deplete natural resources, do not directly or indirectly pollute the environment, and can be reused or recycled at the end of their useful life. They may also be technology that help identify areas of growth by giving feedback in terms of data or alerts allowed to be analyzed to improve environmental footprints. There is significant overlap with appropriate technology, which emphasizes the suitability of technology to the context, in particular considering the needs of people in developing countries. However, the most appropriate technology may not be the most sustainable one; and a sustainable technology may have high cost or maintenance requirements that make it unsuitable as an "appropriate technology," as that term is commonly used.

“Technology is deeply entrenched in our society; without it, society would immediately collapse. Moreover, technological changes can be perceived as easier to accomplish than lifestyle changes that might be required to solve the problems that we face.” The design of sustainable technology relies heavily on the flow of new information. Sustainable technology such as smart metering systems and intelligent sensors reduce energy consumption and help conserve water. These systems are ones that have more fundamental changes, rather than just switching to simple sustainable designs. Such designing requires constant updates and evolutions, to ensure true environmental sustainability, because the concept of sustainability is ever changing – with regards to our relationship with the environment. A large part of designing sustainable technology involves giving control to the users for their comfort and operation. For example, dimming controls help people adjust the light levels to their comfort. Sectioned lighting and lighting controls let people manipulate their lighting needs without worrying about affecting others – therefore reducing lighting loads.

Design and Development

The precursor step to environmentally sustainable development must be a sustainable design. By definition, design is defined as purpose, planning, or intention that exists or is thought to exist behind an action, fact, or material object. Development utilizes design and executes it, helping areas, cities, or places to advance. Sustainable development is that development which adheres to the values of sustainability and provide for the society without endangering the ecosystem and its services. “Without development, design is useless. Without design, development is unusable.” – Florian Popescu, How to bridge the gap between design and development.
