Green retrofit

Green retrofit, home energy retrofit, home retrofit,[1] [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]
