- Deep Energy Retrofit
Holistic construction process to achieve more extensive energy savings than conventional energy retrofits.
- Domestic Hot Water (DHW)
Water heated for other than space heating purposes.
- Energy retrofit
Retrofit that decreases building's energy demand.
- Flat Plate Collectors
Type of solar heat collector that absorbs the energy of the sun and transfers it into hot water. Visually reminds of solar panels.
