The term "sustainable communities" has various definitions, but in essence refers to communities planned, built, or modified to promote sustainable living. Sustainable communities tend to focus on environmental and economic sustainability, urban infrastructure, social equity, and municipal government. The term is sometimes used synonymously with "green cities," "eco-communities," "livable cities" and "sustainable cities."
A Zero-Energy Building (ZEB), also known as a Net Zero-Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows and insulation, and solar panels.
The Association for Environment Conscious Building (AECB) is the leading network for sustainable building professionals in the United Kingdom. Membership of the AECB includes local authorities, housing associations, builders, architects, designers, consultants and manufacturers. The association was founded in 1989 to increase awareness within the construction industry of the need to respect, protect, preserve and enhance the environment and to develop, share and promote best practice in environmentally sustainable building.
Domestic housing in the United Kingdom presents a possible opportunity for achieving the 20% overall cut in UK greenhouse gas emissions targeted by the Government for 2010. However, the process of achieving that drop is proving problematic given the very wide range of age and condition of the UK housing stock.
The Alliance to Save Energy is a bipartisan, nonprofit coalition of business, government, environmental, and consumer groups based in Washington, D.C. The Alliance states that it advocates for "energy-efficiency policies that minimize costs to society and individual consumers, and that lessen greenhouse gas emissions and their impact on the global climate." The Alliance's chief activities include public relations, research, and lobbying to change U.S. energy policy.
The National Energy Foundation (NEF) is an independent British charity, established to improve the use of energy in buildings.
Solar 1 is New York City's only self-sustaining solar powered building. It houses educational facilities for Solar One, a non-profit organisation concerned with green energy, arts, and education. The Solar 1 building is located at the north end of Stuyvesant Cove Park, the city's only all-native plant park, which Solar 1 actively maintains. Situated on a brownfield site, Stuyvesant Cove Park offers opportunities for the local community to become involved in the park and learn about its special features. The Park has been designated a Wildlife Habitat by the National Wildlife Federation for providing a quality habitat by virtue of its standards of conscientious planning, landscaping and sustainable gardening. More than 250 volunteers and 80 student interns have spent more than 5,000 hours working in the park, planting, watering, and weeding the thousands of new plants that have been added over the years.
This article provides examples of green building programs in the United States. These programs span the public, private, and non-profit sectors, and all have the goal of increasing energy efficiency and the sustainability of the built environment.
PACE financing is a means used in the United States of America of financing energy efficiency upgrades, disaster resiliency improvements, water conservation measures, or renewable energy installations in existing or new construction of residential, commercial, and industrial property owners. Depending on state legislation, PACE financing can be used to finance water efficiency products, seismic retrofits, resiliency, and other measures with social benefits.

A Deep Energy Retrofit is an energy conservation project in an existing building that leads to an overall improvement in building performance. While there is no exact definition for a deep energy retrofit, it can be characterized as a whole-building analysis and construction process that aims to reduce on-site energy use by 50% or more using existing technologies, materials and construction practices. Reductions are calculated against baseline energy use using data from utility bills. Such a retrofit reaps multifold benefits beyond energy cost savings, unlike conventional energy retrofit. It may also involve remodeling the building to achieve a harmony in energy, indoor air quality, durability, and thermal comfort. An integrated project delivery method is recommended for a deep energy retrofit project. An over-time approach in a deep energy retrofitting project provides a solution to the large upfront costs problem in all-at-once execution of the project.
The Sustainable Endowments Institute (SEI) is a nonprofit organization based in the United States that is engaged in research and education to advance sustainability in operations and endowment practices. Founded in 2005, SEI is a special project of Rockefeller Philanthropy Advisors. SEI is located in Boston, Massachusetts.
Green affordable housing is reasonably priced housing that incorporates sustainable features. The phenomenon has become increasingly common in all over the world as climate change and the cost of housing become alarming issues. For example, the United States adopted state and local policies that favor or require green building practices for publicly owned or funded buildings. Potential benefits of green affordable housing include lower energy cost burden and improved health. One challenge to green affordable housing is the tendency to prioritize short-term costs over long-term benefits, leading to higher upfront cost. The challenge for green housing advocates is to see to the life cycle cost of the building. Many affordable housing projects already find it a challenge to raise capital to finance basic affordable housing. This challenge is compounded by the phenomenon of urban greening and environmental gentrification, which can drive up housing prices and becomes a challenge for green affordable housing. Green affordable housing has taken form in traditionally wooden homes, green homes and most recently with 'upcycling' shipping containers.

Sustainable refurbishment describes working on existing buildings to improve their environmental performance using sustainable methods and materials. A refurbishment or retrofit is defined as: "any work to a building over and above maintenance to change its capacity, function or performance' in other words, any intervention to adjust, reuse, or upgrade a building to suit new conditions or requirements". Refurbishment can be done to a part of a building, an entire building, or a campus. Sustainable refurbishment takes this a step further to modify the existing building to perform better in terms of its environmental impact and its occupants' environment.
Conservation Services Group (CSG) is a nonprofit energy efficiency and renewable energy company that has provided program design and management services to energy efficiency program sponsors and energy professionals in the United States since 1984. CSG was bought by CLEAResult in July 2015.
Sustainable Energy Utility (SEU) is a community-based model of development founded on energy conservation and the use of renewables, seeking to permanently decrease the use of source materials, water, and energy. The model prescribes the creation of independent and financially self-sufficient non-profit entities for energy sustainability through conservation, efficiency, and end-user based decentralized renewable energy. The intent of SEU is to address concerns about climate change, rising energy prices, inequity of energy availability, and a lack of community governance of energy development. The SEU model was developed by Dr. J. Byrne at the Center for Energy and Environmental Policy, University of Delaware. The Foundation for Renewable Energy and Environment (FREE) is implementing versions of the model.
Public plans for energy efficient refurbishment are put in place by states to encourage building owners to renovate their properties in a way that increases their energy performance. As financing represents the most important obstacle to this type of renovation, the plans favour financial incentives in the form of loans or grants. Various institutions can be involved in the process, such as ministries, banks, firms, or energy services companies (ESCOs).
Energiesprong is a program that originated in the Netherlands that introduced and retrofitted houses that satisfy energy efficient standards. It has since been implemented in the United Kingdom, the United States, France, and Canada. The program typically consists of snapping a shell of panels to the outside of a building to increase its thermal efficiency.
