The built environment refers to "the human-made space in which people live, work and recreate on a day-to-day basis" (Roof and Oleru 2008). The built environment influences land availability and land-use decisions for energy generation, water transmission, agriculture and ecosystems. The design strategies used in the built environment directly affect energy and water use and surrounding land areas. The location of new buildings also affects transportation options and it has subsequent impacts on transportation systems, water and wastewater systems, and the power grid.
