Energy Efficiency and Renewable Energy Resources  
Commercially available, cost-effective energy technologies could reduce overall energy consumption in the United States by as much as one-third--worth some $343 billion. This link provides information on strategies such as proper siting and airtight construction, as well as installing energy-efficient equipment and appliances and renewable energy systems. Such technologies can reduce the amount of energy your building needs to operate and to keep its occupants comfortable.

Environmental Impact 
The built environment has had a tremendous impact on the environment. However, your building can interact more positively with the environment if you pay special attention to preserving the site’s integrity and natural characteristics, landscaping appropriately, and selecting materials that have lower embodied energy and those that are produced locally.

Resource Conservation  
Conserving resources is a cornerstone of green building techniques. There are many ways to conserve resources during the building process. For example, selecting materials that have at least some recycled content can conserve natural resources and virgin materials. Minimizing construction waste can ease the impact on landfills and resources. Installing water- and energy-efficient products can conserve resources while reducing operating costs. Choosing a green (plant-covered) roof can reduce energy use, cool urban heat islands, and prevent stormwater runoff, as well as contributing to wildlife habitat and air quality.

Indoor Air Quality  
Energy-efficient buildings are more airtight and therefore hold greater potential for indoor air quality problems, especially if not properly ventilated. Building products can contribute to poor air quality, but these potential problems can be reduced by selecting materials lower in chemicals and toxins, and installing mechanical ventilation systems to ensure an adequate fresh air supply.

Community Issues  
Placing green building projects within easy access of public transportation, medical facilities, shopping areas, and recreational facilities decreases the need for automobiles and encourages bicycling and walking. In addition, successful green buildings blend into the community, preserving natural and historical characteristics, and will utilize existing infrastructure in order to reduce sprawl. Cohousing represents one approach to creating a community of green buildings.
