The built environment accounts for approximately half the energy use and carbon footprint of the United States. Lean Buildings reduce energy flows by tapping basic natural heating and cooling techniques and renewable energy sources in ways that are region-specific and climate-sensitive. Seven defensive and offensive strategies — from use of local and recycled materials to heavy insulation, from building orientation and passive solar systems to dense urban configurations — address the reduction of material and energy consumption in the U.S and similar climates. Issues of energy quantity and quality, energy codes and metrics, as well as building size and configuration, are also discussed.read more
