In the residential sector, GHG mitigation technologies can be divided into three groupings: building envelope strategies, building equipment strategies and renewable energy strategies. Building envelope strategies address the size, shape, orientation, and thermal integrity of the residential unit. Examples of mitigation technologies include increased wall and roof insulation, advanced window technologies, roof coatings, and reduced or controlled infiltration. Building equipment strategies improve the space heating and cooling, lighting, cooking, refrigerators, water heating, clothes washing and drying, air conditioning and other household appliances used in homes. Examples include such advanced technologies as condensing furnaces, compact fluorescent lamps and advanced refrigerator compressors. The renewable energy strategies include passive solar building designs and active solar water and space heating systems, ground-source heat pumps, daylighting strategies, and photovoltaic systems. In the residential subsector, the choice of technologies will vary greatly due to climate, between single-family residences and multi-family apartment buildings, and between urban and rural (traditional) communities.
