Sustainable urbanism

Sustainable urbanism is:

  1. In common speech, the use of the adjective "sustainable" in conjunction with the noun "urbanism", meaning urbanism that is sustainable.
  1. A defined term advanced in the book Sustainable Urbanism by Doug Farr.

Sustainable Urbanism, as a defined term, is application of Ecocity movement (also known as Ecological Urbanism) which specifically is looking to make cities based on ecological principles, and the Resilient Cities movement addresses depleting resources by creating distributed local resources to replace global supply chain in case of major disruption. Green urbanism is another common term for sustainable urbanism. Sustainable development is a general term for both making both urban and economic growth more sustainable, but isn't specifically a mode of urbanism.

Sustainable urbanism aims to close the loop by eliminating environmental impact of urban development by providing all resources locally. It looks at the full life cycle of the products to make sure that everything is made sustainably, and sustainable urbanism also brings things like electricity and food production into the city. This means that literally everything that the town or city needs is right there making it truly self-sufficient and sustainable.

Sustainable Urbanism: Urban Design With Nature , by Doug Farr (2007)

The architect and urban planner Doug Farr discusses making cities walkable, along with combining elements of ecological urbanism, sustainable urban infrastructure, and new urbanism, and goes beyond them to close the loop on resource use and bring everything into the city or town. It is about increasing the quality of life by bringing more resources within a short distance and also increasing the quality of products that are offered.

Comparison of similar principles

New Urbanism inspired Farr's definition of Sustainable Urbanism is based around bringing everything closer together, using higher quality goods, being more efficient, and having everything within walking distance, but Sustainable urbanism closes the loop.[1][2] The criticism of New Urbanism is that it attempts to apply 19th century urban form to 21st century cities and that New Urbanism excludes economic diversity by creating expensive places to live that are highly privatized and controlled.

Smart growth approach as conceived by planners helps achieve greater jobs–housing balance, but it is likely to leave sense of place unaddressed. While New Urbanism may fulfill that dimension, it is not viewed as an approach that will lead to communities that are energy self-reliant. The ecological city approach seems to complementary to the other two approaches in terms of their respective areas of strengths and weakness.[3]

Green urbanism probably contains the most similar ideas with sustainable urbanism. They both emphasize on urban design with nature, as well as shaping better communities and lifestyles. However, the principles of green urbanism are based on the triple-zero framework: zero fossil-fuel energy use, zero waste, and zero emissions. Sustainable Urbanism, on the other hand, is more focused on designing communities that are walkable and transit-served so that people will prefer to meet their daily needs on foot.

Defining elements of Sustainable Urbanism


Compactness, or density, plays an important role in sustainable urban development because it supports reductions in per-capita resource use and benefits public transit developments. The density of new development across the U.S. averages roughly two dwelling unit per acre, which is too low to support efficient transit and walk-to destinations. Such low-density development is a characteristic of urban sprawl, which is the major cause of high dependence on private automobiles, inefficient infrastructure, increased obesity, loss of farmlands and natural habitats,pollution, and so on.[4] For these reasons, sustainable urbanism requires minimum development densities roughly four times higher than two dwelling units per acre.

Overall, compact development generates less pollutants to the natural world. Research has shown that low-density development can exacerbate non-point source pollutant loadings by consuming absorbent open space and increasing impervious surface area relative to compact development.[5] While increasing densities regionally can better protect water resources at a regional level, higher-density development can create more impervious cover, which increases water quality problems in nearby or adjacent water bodies.

Increasing neighborhood population density also supports improved public transit service. Concentrating development density in and around transit stops and corridors maximizes people's willingness to walk and thus reduces car ownership and use. Sustainable urbanism seeks to integrate infrastructure design increase with density, because a concentrated mixed-use development required less per capita infrastructure usage compared to detached single-family housing.[6]


The concept of Biophilia hypothesis was introduced by E. O. Wilson. It refers to the connection between humans and other living systems. Within this concept, humans are biologically predisposed to caring for nature. In Douglass Farr’s book, Sustainable Urbanism: Urban Design with Nature, he links open spaces such as parks and recreational areas, sustainable food production and agricultural land use practices with humans’ concern and relationship with natural systems. Therefore, biophilia is a crucial underlying component of sustainable urbanism.[7][8]

Sustainable corridors

Sustainable corridors are similar to a wildlife corridor in that they connect one area to another efficiently, cheaply, and safely. They allow people to pass from their immediate proximity to another without relying on cars or other wasteful and inefficient products. It also relys on accessibility to all people in the community so that the mode of transportation is the most convenient and easiest to use for everyone. Sustainable Corridors also include biodiversity corridors to allow animals to move around communities so that they may still live in and around cities.[9]

High performance buildings

High performance buildings are designed and constructed to maximize operational energy savings and minimize environmental impacts of the construction and operation of the buildings. Building construction and operation generates a great deal of ‘externalized costs’ such as material waste, energy inefficiencies and pollution. High performance buildings aim to minimize these and make the process much more efficient and less harmful. New York City Department of Design & Construction put out a set of guidelines in April 1999 on High performance buildings that have broad application to sustainable urbanism as a whole worldwide.[10]

The amount of energy use of a building is determined by two types of heating/cooling loads or in other words the amount of heating or cooling needed to keep the interior at a reasonable temperature. Internal loads: the lighting, people, equipment, and ventilation system used inside the building, and external loads: the construction of the walls, roofs, and windows and how that influences energy flow.[11]

By incorporating environmentally sound materials and systems, improving indoor air quality and using natural or high efficiency lighting, it minimizes a building impact on its natural surroundings; additionally, those who work or live in these buildings directly benefit from these differences. Some building owners have even reported increased worker productivity as a result of the improved conditions. However, because these other benefits are more difficult to quantify than direct energy savings, the real value of high performance buildings can easily be underestimated by traditional accounting methods that do not recognize ‘external’ municipal and regional costs and benefits. The cost evaluations of high performance building should account for the economic, social, and environmental benefits that accompany green buildings.[12]

High performance building features and benefits

[13] The following design, construction, and operation activities can result in value-added public buildings. Direct, indirect, and ‘external’ benefits can also be identified.

  • Energy efficiency/clean energy resources

Reduce energy use and demand through passive solar techniques and integrated building design. This process looks at optimum orientation and maximizes the thermal efficiency of the building envelope (windows, walls, roof) while also considering the interaction of the HVAC, lighting, and control systems. Integrated design uses daylight to reduce electrical demand, and incorporates energy efficient lighting, motors, and equipment. Where feasible, renewable energy sources such as photovoltaic cells, solar hot water, and geothermal exchange are used in tandem with other low emission technologies, such as fuel cells. This results in direct energy cost savings (fuel and electricity) yield a good rate of return based on the initial investment. Other external benefits include improved air quality from reduced fuel consumption (limiting nitrous oxide, sulfur dioxide, methane, and other gases that contribute to air pollution). Additionally, reducing the overall aggregate electrical load significantly reduces carbon dioxide emissions.

  • Improved indoor environment

Improve indoor air quality by eliminating unhealthy emissions – such as volatile organic compounds (VOCs) – from building materials, products, and furnishings, and through outside filtering and distribution techniques that control pollutants. Maximize the use of controlled daylighting, which can then be augmented by high quality artificial lighting. Provide good acoustic control. Results in high performance facilities can help address a wide range of human resource concerns by improving the total quality of the interior environment. In addition, attention to building wellness today helps avoid future costs of corrections. Such ‘well building’ design emphasis can improve occupant comfort, health, and well-being, in turn reducing employee absenteeism and turnover.

  • Source reduction, pollution prevention and recycling

Renewable resources, and are themselves recyclable, and that have been manufactured in a manner less damaging to the environment. Implement construction and demolition (C&D) waste prevention/management strategies and selective site sorting of materials for salvage, recycling, or disposal. These actions will prevent unnecessary depletion of natural resources and will reduce air, water, and soil pollution. They will also strengthen the market for recycled materials, and the manufacture of products with post-consumer content. Long-term, better C&D waste management can reduce waste disposal costs, ease stress on landfills, and minimize the cost of transporting waste to disposal facilities outside the City.

  • Building operations resource management

Design in ways that promote good building operations practices: water conservation measures, create space for everyday waste recycling, and improve housekeeping practices through use of benign cleaning products and more efficient cleaning and maintenance protocols. Water conservation measures will help maintain a city’s water quality and avoid potential future costs by reducing overall loads on water filtration and treatment systems.

Barriers to high performance building

General lack of knowledge in the industry on high performance building as well as rapid payback mandated for investments in sustainable technologies. Slower returns need to be made acceptable so that more investments can be made. Often it difficult to get funding for such projects that are not obvious to the onlooker as well as not offering many financial incentives. Also, there are many regulatory disincentives.[14]

High performance infrastructure

High-performance infrastructure refers to core best management practices (BMPs) applicable to the typical section of the public right-of-way, encompassing street sidewalk, underground utilities, stormwater infrastructure, landscapes, and streetscape elements. In addition to many public health and environmental benefits, financial benefits include decreased first costs, decreased operation and maintenance costs, decreased energy costs and increased real estate values.[15]

  • Component optimization

At the single-component level, standard details may be improved to optimize performance, minimize environmental impact, use materials more efficiently or extended lifecycle. Examples include using reclaimed supplementary cement materials to increase pavement strength or designing water-efficient landscapes to reduce irrigation needs and water consumption.

  • Multifunctional optimization

Improving single components does not consider the whole system in place, so multifunctional optimization guidelines seek to minimize conflicts among parts and promote synergies. This could lead to long-term savings, improved performance and lifecycle, and increased returns on municipal investments. One example is using permeable pavement to reduce stormwater runoff and peak demand on stormwater management infrastructure while providing an adequate driving surface for vehicles.

  • Integrated design

Systems-oriented design focuses on improving the performance of the entire roadway system. It requires cross-disciplinary teamwork at the planning, scoping, design and construction phases. It promotes comprehensive performance improvements, compounds environmental benefits and potentially offers substantial cost savings. An example of integrated design would be designing a roadway with a diversely planted center median that functions as both a traffic-calming device and a stormwater bioretention area to improve pedestrian safety, minimize stormwater runoff, dampen street noise and improve air quality.

Examples of sustainable urbanism

Newington, Sydney, Australia

A suburb in western Sydney, Australia, Newington, was the home to the athletes of the 2000 Summer Olympics and 2000 Summer Paralympics. It was built on a brownfield site, and it was developed by Mirvac Lend Lease Village Consortium from 1997. Redevelopment of the village was completed in 1999, but further development is still occurring. After the Games, Newington stimulated the Australian market for green products, and it became a solar village housing approximately 5,000 people. Unfortunately, the development failed to build neighborhood centers with walk-to services, which perpetuates automobile dependence. Furthermore, Newington does not provide any affordable housing.

Key Sustainable Urbanism Thresholds:

  • High performance buildings: Solar panels are installed in every home in Newington. “At the time of its construction it was the largest solar village in the world… The collective energy generated by these photovoltaic panels will prevent 1,309 tons of CO2 from entering the atmosphere per year, the equivalent of 262 cars being taken off the road.[16] ” By using window awnings, wool insulation, slab construction, and efficient water fixtures, over 90 percent of the homes are designed to consume 50 percent less energy and water than conventional homes.
  • Sustainable corridors and biophilia: At Newington, 90 percent of the plantings are native species. 21 acres of the development site is incorporated into the Millennium Parklands. 40 percent of stormwater runoff infiltrates the groundwater supply and the rest is cleansed on-site and channeled to the ponds in the Parklands, providing important habitats. In addition, The Haslams Creek was rehabilitated from a concrete channel to a natural watercourse.

Dongtan, Shanghai, China

Dongtan is a development in Eastern Chongming Island, which is roughly a one-hour trip from downtown Shanghai. It was once planned as “the world’s first eco-city,” attempting to become an energy self-sufficient, carbon-neutral, and mostly car-free eco-city housing 500,000 residents. The first phase of the development is supposed to complete by 2010, and entire development by 2050, but the Dongtan project has been delayed indefinitely due to financial issues, among other things.[17]

Key sustainable urbanism thresholds:

  • Compactness: Dongtan is planned to achieve densities of 84-112 people per acre, which will support efficient mass transit, social infrastructure, and a range of businesses. Most homes will mid-rise apartment buildings clustered toward the city center. Parks, lakes and other public open space will be scattered around the densely designed neighborhoods.
  • High performance Infrastructures: Dongtan is designed to utilize various types of rice husks.

Upton, Northampton, England

Upton is part of the southwest district of Northampton, England, lying between the existing town edge and the motorway. Originally farming land, Upton was developed by English Partnerships, the national regeneration agency for England, with high standards of building and design codes. The planning outline started in 1997, and the sites were planned to be completed by 2011.[18]

Key sustainable urbanism thresholds:

  • High performance buildings and infrastructure: The Upton development is planned to employ sustainable urban drainage systems (SUSD), controlling the flow and quality of water entering the sewage system. Other green technologies being implemented include green roofs, microcombined heat and power (micro-CHP), rainwater harvesting systems, and PV systems.
  • Sustainable Neighborhoods: Upton is currently developing its transit system. As soon as the first residents move in, a twice-hourly bus service will begin running in the neighborhoods. A car sharing program is also proposed. The development is achieving its social sustainability by requiring that 22 percent of scattered units be permanently affordable housing.

  • The LEED for Neighborhood Development (LEED-ND) is the nation’s first rating system for green neighborhoods. The LEED-ND was created out of a partnership with the Congress for New Urbanisim, the U.S. Green Building Council (USGBC), and the Natural Resource Defense Council (NRDC). It provides a coordinated environmental strategy to achieve sustainability at the level of entire neighborhoods and communities. LEED-ND is a rating system that certifies green neighborhoods, building off USGBC’s Leadership in Energy and Environmental Design (LEED), which is a third-party verification system that a development meets high standards of environmental responsibility. LEED-ND combines the principles of new urbanism, green building, and smart growth to create the first accepted national standard for neighborhood design that extends LEED’s scope beyond the individual to a more holistic (neighborhood/community) perception of the context of the buildings.[19]


SmartCode is A Form-based code that incorporates Smart Growth and New Urbanism principles.

Criticisms of Sustainable Urbanism

Not much has been said criticizing Sustainable Urbanism, but there are critiques of New Urbanism. Critics say New Urbanism is too nostalgic and the designs seem artificial. Critics also charge that New Urbanism has largely failed to attain its goals of diversity, as the idea attracts mostly white, affluent residents.[20]

There are professionals who are concerned that the use "Sustainable urbanism" as a label risks debasing the term "sustainable", with developments being labeled as examples of "Sustainable Urbanism", which, while substantially better than much modern development, are not truly sustainable according to the Brundtland definition of sustainability.

Also, critics believe that, while the New Urbanism contains many attractive ideas, it may have difficulty dealing with a wide range of contemporary issues including scale, transportation, planning and codes, regionalism, and marketing.[21]
