"The Ballard Passive House is proof that high performance building approach is taking root in Seattle," Hammer And Hand's Dan Whitmore said. "And that's great news for the future of our buildings and our planet."

Hammer And Hand's Seattle remodeling and building division announced today the start of its Ballard Passive House project, a new high performance home designed by VELOCIPEDE architects. Builder Dan Whitmore, creator of Seattle's first Passive House, Courtland Place, will lead construction of the home as Hammer And Hand's Seattle project supervisor. The Ballard Passive House is part of a second wave of Seattle Passive House (aka 'Passivhaus') construction going on across the city.

"The Ballard Passive House, and its sister projects currently underway by our Seattle green building colleagues, is proof that the high performance building approach is taking root in Seattle," Whitmore said. "And that's great news for the future of our buildings and our planet."

Passive House buildings harness cutting-edge building science knowledge and energy modeling to achieve revolutionary gains in energy performance using existing, straight-forward technologies. The results:

  • 90% reduction in heating energy demand compared to conventional structures;
  • Excellent indoor air quality with continuous supply of fresh air from heat recovery ventilation;
  • Superior, draft-free thermal comfort;
  • Durable construction through careful control of air and moisture throughout building assemblies.

The client for the new Ballard home was drawn to super-efficient building out of concern for his three nieces and future generations. He chose Passive House because the standard's transformational impact on building energy consumption is so doable.

"If you can show a better way of building houses without any real changes to lifestyle," the client said, "it's better for all of us.  That's what Passive House is about.  And, it's a good bang for the buck with existing technologies."

The Ballard home will be constructed with 2x8 walls and wrapped with a continuous layer of EPS (Expanded Polystyrene) foam.  Newly available triple-glazed windows will bring high performance at a cost-competitive price point.  The home will employ Passive House design and construction to reach near-net-zero energy consumption.  A future photovoltaic system will make the house net-energy positive.

"It was great to have a client come forward and say, 'I want a super-efficient home,'" Whitmore said.  "I said, 'excellent, we can do that for you!' It's a privilege to be building the Ballard Passive House."
