a competition to produce plans for a building that conserves construction and demolition materials and reduces greenhouse gas emissions

an international network of ecological builders working together for a sustainable future

goal is to achieve a dramatic reduction in the global-warming-causing greenhouse gas (GHG) emissions of the Building Sector by changing the way buildings and developments are planned, designed and constructed

a new science that studies nature's models and then imitates or takes inspiration from these designs and processes to solve human problems

focuses on the concept of natural building, making it easier for people to either build or renovate their homes with sustainability in mind

combining conventional engineering, innovative ecological design, and permitting knowledge to build water and energy conservation systems

developing an ecovillage that will be a model of sustainable land use and will feature public outreach and education

helps building owners, managers, and tenants improve the energy efficiency of their buildings worldwide, providing a voluntary, no-cost approach to improved energy efficiency

the U.S. Department of Energy provides information on the benefits of energy-efficient windows, descriptions of how they work, and recommendations for their selection and use

the Alliance to Save Energy helps schools use energy efficiently through building retrofits, changes in operational and maintenance routines, and changes in the behavior of building users

the UK's first earth sheltered, self-sufficient ecological housing development; generating clean energy, harvesting water and recycling waste materials causing no pollution or emissions

a report by the Environmental Change Institute that identifies the policies needed to deliver an 80 percent cut in carbon emissions from UK homes by 2050(pdf)

works to to further the development of minimized mechanical systems for heating, cooling, and dehumidification nationwide including constructing, measuring, and verifying performance of Passive Houses in all US climate zones

college and university teams in a competition to design, build, and operate the most attractive and energy-efficient solar-powered house

a nonprofit organization whose mission is to advance the design, affordability, energy performance, and environmental soundness of residential, institutional, and commercial buildings nationwide

devoted to exploring the relationship between ecology and sustainability; seeking to to nourish and strengthen ecologically oriented design, construction and lifestyle choices

monitors the progress of the development of a Green Building Council for the United Kingdom

coalition of leaders from across the building industry working to promote buildings that are environmentally responsible, profitable, and healthy places to live and work

devoted to information, resources, tools about green buildings and environmental design

principles of eco-design presented by documenting how a regular U.K. house was turned into an environmental dream home with drastically reduced energy consumption

a large directory of environmental building design and construction resources on the net; including information on green building and eco construction products of various types
