Buildings have a tremendous impact on the environment. In North America, buildings and the building industry account for about 30% of carbon dioxide emissions, 35-40% of ozone depletion, 20-30% of municipal solid waste, vast quantities of natural resource consumption, and dramatic loss of open space each...
