DOE Tour of Zero: Passive House #1 at Columbia Station by Dwell Development
You are here
This Seattle home by Dwell Development is certified to the strict performance standards of the U.S. DOE Zero Energy Ready Home program, as well as those of the Northwest ENERGY STAR program, Passive House Institute U.S., and the regional Built Green program.
This three-story modern high-performance home by Dwell Development provides its homeowners with enhanced comfort and durability, as well as low energy bills of less than $500 per year.
Solar window shading is built into the design of the three-story home to minimize heat gain from high overhead summer sun while allowing low winter sun into the natural daylight home.
The high-performance home has a rooftop deck on the third floor, providing views and maximizing space on the infill site.
The Zero Energy Ready Home is one of 42 homes in a micro-community of ultra-modern, energy-efficient homes built on an urban gray-field site in South Seattle.
The single ultra-efficient ductless heat pump (10.6 HSPF, 23 SEER), shown mounted on the wall at the upper left, provides all the heating and cooling the 2,000-square-foot home needs. The heating and cooling requirements are substantially reduced by the 14-inch-thick double-wall thermal blanket construction with insulation and ultra-efficient triple-pane windows.
Advanced lighting technology, including compact fluorescent fixtures, help reduce energy use.
Ultra-efficient triple-pane windows fill the home with natural light and minimize the transfer of heat in or out with advanced technology coatings.
High-efficiency appliances, including an ENERGY STAR-rated dishwasher, clothes washer, and refrigerator, save energy and water.
The home meets all of the criteria of the EPA’s Indoor airPLUS program, including the requirement to use low-/no-VOC containing cabinetry and finishes.
A recycled-glass countertop surrounds the bathroom sink. The faucet, like all the plumbing fixtures in the home, is a water-saving EPA WaterSense-labeled fixture.
An on-demand hot water plumbing system uses central manifold plumbing distribution with PEX piping directly to each fixture to significantly reduce waiting time and wasted water.
Endless hot water heating technology is also ultra-efficient.

"We looked for a long time, and we were finding the choice between bad and worse. This house is so preferable – to have the opportunity to be in a home that is so well-built. It’s double-checked. We like the fact that there are standards in place."
