Deep Energy Retrofits (DERs) are at the cutting edge of the residential building industry. These ambitious projects aim to take existing homes and transform them into extremely low-energy homes. While the exact definition of a DER is not yet clear, most experts consider energy reductions greater than 50% to be readily achievable with existing technologies, materials, and construction practices. These drastic energy cuts are typically achieved using a combination of comprehensive building enclosure improvements, HVAC and domestic hot-water system replacement, lighting and appliance upgrades, and sometimes the addition of renewable energy. In addition to these building system improvements, energy conservation by the occupants plays a critical role in the success of DERs. When you are looking for low environmental impact in housing choices, a DER is a viable alternative to a new home—one that minimizes environmental footprint, maintains historical character, and achieves exceptional energy performance and occupant satisfaction.
