Green retrofit, home energy retrofit, home retrofit,[1] Deep energy retrofit and home performance retrofit[2] are terms with overlapping meaning for retrofits that ensure the maintenance and preservation of buildings and the continued operation and maintenance of energy efficiency technologies.[3] The meaning ranges from steps home owners can do themselves[4] to buying up distressed properties and making them certifiably green.[5] In the United States, the DOE issued a solicitation for $390 million for a "Retrofit Ramp-Up" program.[1] Simple steps Steps home owners can do include the following:[4] - Insulation, primarily roof/ceiling/attic and secondary walls and floor
- Retrofitting heating equipments in older houses, results in household savings of 30–80% due to cut in energy-use and a reduction of {{CO2}}-outlets by 30–100%.[6]
- Thermostats in all rooms
- New windows.
- Plugging air leaks.
- Tuning up heating and cooling (HVAC) systems.
- Switching to compact fluorescent light bulbs and/or LED light bulbs
- Choosing appliances with low energy consumption. In the United States, this is certified by the Energy Star.
- Reducing water use by installing aerators and low-flow showerheads
- Switching to green power, including solar energy and renewables such as heating-pellets and bio-gas
- Using low-VOC products to improve indoor air quality
- Planting native plants and other appropriate landscaping measures.
