New Seattle Home Construction Project on its Way to Achieving World’s Most Stringent Energy Performance Standard, Passive House

The Ballard Passive House, designed by VELOCIPEDE architects and built by Hammer & Hand, easily beats air tightness standard for Passive House, showing it is well on its way to Passive House certification.

Ballard Passive House by Seattle New Home Builder Hammer & Hand

We’re all really excited about the initial results,” said Hammer & Hand project lead Dan Whitmore. “We found a couple of pinhole leaks but that’s not bad for the first time out. Now we’re set and we’re ready to rock-and-roll on the exterior.”

Seattle, WA (PRWEB) March 29, 2013

Home builder and contractor Hammer & Hand announced today the results of its initial blower door test at the Ballard Passive House. The still-under-construction home clocked in at an impressively airtight 0.29 ACH50 (0.29 air changes at 50 pascals of pressure) on its first test, easily beating the maximum value allowed by the Passive House standard of 0.6 ACH50.

“We’re all really excited about the initial results,” said Hammer & Hand project lead Dan Whitmore. “We found a couple of pinhole leaks but that’s not bad for the first time out. Now we’re set and we’re ready to rock-and-roll on the exterior.”

With heating energy demand reductions of 90% coupled with superior air quality, thermal comfort, and building durability, it is easy to see the appeal of Passive House construction. But when the Passive House building standard was introduced here from Germany, some wondered if North American builders were up to the task of this new level of high performance building.

“There was a lot of skepticism whether or not North American builders could achieve the required air tightness for Passive House certification,” said Passive House consultant Skylar Swinford of Hammer & Hand. “But with a solid plan and attention to details, achieving the minimum standard or better is completely doable.”

The initial blower door tests results of the Ballard Passive House support this claim and suggest that Passive House construction is a practical way for the North American industry to build sustainable and comfortable new homes.

Construction at the Ballard Passive House continues to progress, and the latest developments will be on view to the public at the 3rd annual Northwest Green Building Tour April 27th, 2013. The tour runs from 11am-5pm and is a free event.
