Clifton View Homes built this 2,417-square-foot custom home in Snohomish, Washington, to the high performance criteria of the U.S. Department of Energy Zero Energy Ready Home (ZERH) program.
The standing-seam metal roof, deep overhangs, and fiber cement plank siding over draining house wrap help to keep the home dry in this often-damp Pacific Northwest location.
The south-facing roof is covered with 8.1 KW of photovoltaic panels, helping this home to produce more energy than it uses in a year.
The large south-facing windows allow any available sunlight to warm up the stained concrete floor slab, providing passive heating to the home.
High-performance ENERGY STAR appliances save energy and water.
Interior windows help convective loops carry radiant floor heat into upstairs bedrooms.
Low-flow fixtures minimize water use while a compact plumbing design reduces wait times for hot water.
For cooling, the home primarily uses ceiling fans and night ventilation with a 240-cfm fan that draws fresh outside air into the home through a HEPA filter.
The very high efficiency (4.7 COP) ground source heat pump provides hot water for radiant floor heat and domestic hot water.
The garage was pre-wired for an electric car charging station.
