Careful attention to site selection takes into consideration such future needs as access to public transportation, parking capacity, accommodation for alternative fuel vehicles, protection or restoration of open space, storm water management, and prevention of the heat island effect and light pollution.
Water-efficient landscapes, water-efficient equipment and appliances, and innovative wastewater technologies are employed to reduce costs, help preserve water supplies and prevent pollution.
Green building incorporates a variety of energy-efficiency measures such as use of daylighting, renewable energy, superior insulation, and high-efficiency appliances and equipment.
Reduction of greenhouse gas and CFC in HVAC and refrigeration to preserve and protect the environment are examples of important elements of green building.
Wiser Use of Materials and Resources
All materials used in construction should provide the best value in terms of the life of the product and future maintenance costs. At the same time, materials must be selected with environmental concerns in mind. Green builders consider not only the finished products they will use in construction, but also the methods of raw material acquisition, product manufacturing, packaging, transportation and use. Green building also means being conscious of waste management. Recycling and reusing materials when practical helps prevent the overuse of landfills.
Indoor Environmental Quality
Green buildings provide good indoor air quality, lighting, acoustics and temperature control for the health and comfort of inhabitants. This requires the use of environmentally-friendly building materials and innovative designs, with special attention to the ventilation, insulation, and heating and air-conditioning systems.
