DOE Tour of Zero: Mt. Baker House by Dwell Development
You are here
Dwell Development built this 3,180-square-foot custom home in Seattle, Washington, to the high performance criteria of the U.S. Department of Energy Zero Energy Ready Home (ZERH) program.
Reclaimed barn wood provides a striking exterior for this high-performance home.
Beneath the reclaimed metal and wood siding the 2-by-6 walls are dense packed with R-23 of fiberglass insulation, and covered with OSB that is protected by a seamless layer of fluid-applied weather barrier.
The high-performance triple-pane, low-emissivity windows minimize heat loss while flooding every floor with natural light.
Pervious pavers allow rainwater to percolate into the soil on site rather than flowing into the street.
A variety of balconies and patios encourage the natural ventilation of open doors despite the tight urban lot lines.
The heat recovery ventilator fresh air system provides continuous exhaust balanced with filtered fresh air.
High-performance ENERGY STAR appliances save energy and water.
Advanced-technology ductless heat pumps provide heating at 10.3 HSPF and cooling at 19.7 SEER, well above the minimum federal requirements.
A heat pump hot water heater provides plenty of hot water, but water waste is minimized with EPA WaterSense rated low-flow fixtures and a timer-operated recirculation pump on the furthest hot water runs.
