Buildings are often placed where they are most convenient, without considering the possible affects the building may have on the landscape and chosen site. Because of this, site selection has an important bearing on the planning and design of a building. Proper site selection takes into consideration the effects of the building on the location and landscape, environmental concerns such as ground water and storm water flow and wildlife habitat, the amount of sunlight the building receives,and the exposure of the building to wind. The perfect location or site for a green building can cut energy costs as well as reduce the environmental impact upon the land. Other things to consider are available facilities and necessities such as police and fire protection, waste services, and street cleaning.
