Project Profile: View Haus 5

Tadashi Shiga, principal, Evergreen Certified, Seattle, described View Haus 5 as “the now and the future of HVAC.” Recent industry recognition supports that: View Haus 5 is the Seattle area’s first Passive House-certified multifamily building and winner of the Passive House International US Completion Award, which honors the country’s best Passive projects.

Bradley Khouri, principal and founder, b9 architects, Seattle, designed the sustainable community. The five 1,100- to 1,700-square-foot homes feature century-old, reclaimed barn wood; LED lighting; walls over a foot thick; zero-VOC paints; airtight, tilt-turn windows – and our ductless multizone comfort systems.

“We needed the most efficient HVAC system out there,” said Sloan Ritchie, president and founder of Cascade Built. Our ductless system had a low enough load, a small enough footprint and high enough efficiencies to earn View Haus 5 multiple energy-focused certifications, including Passive House. Khouri said our systems are “great for uses like this because of their small size. And they provide incredible performance for such a small device.”

There’s even more proof in the pudding: One of the homes, a 1,431-square-foot unit, has a HERS Index of 47 and an annual energy cost of just $63 – an energy expenditure a tenth of its non-Passive neighbors.
