A Deep Energy Retrofit is a whole-building analysis and construction process that uses integrative design to achieve much larger energy savings than conventional energy retrofits. Deep Energy Retrofits can be applied to both residential and non-residential or commercial buildings. DER typically results in savings of 30% or more, perhaps spread over several years, and may significantly improve the building value. The term is often used interchangeably with Deep Green Retrofit and Deep Retrofit.
