Promethean Homes’ Chisholm Place project scored a 33 on the HERS Index (without any renewable energy generation!) and achieved EarthCraft Platinum certification (the highest certification level possible). The house won a DOE’s Zero Energy Ready Home Challenge as well as certified as Energy Star, and EPA WaterSense and Indoor airPLUS. Promethean used a number of leading edge methods and technologies including nearly air-tight construction with a blower door test result of just 0.02cfm50/ft2, super-insulated walls (R-30), slab (R-16) and ceiling (R-67), along with triple pane windows. The HVAC system features two, high efficiency ducted mini-split heat pumps, along with a high efficiency ERV for whole-house ventilation. Water heating is provided by a heat pump water heater, all appliances are Energy Star certified and nearly all lighting is LED. The house was made accessible, built in a walkable neighborhood on an in-fill lot in downtown Charlottesville. This Platinum EarthCraft home is a model example of the future of housing.
