The largest Passive House in the nation will be completed within a year in Hillsboro, Oregon, the Oregonian reports.
The Passive House structure will be the first of three phases for the Orchards at Orenco project, which aims to construct mixed-availability buildings and provide 150 units of affordable housing.
The Passivhaus ("Passive House" in the U.S.), a concept founded in the 1990s by German physicist Wolfgang Feist, is a strict building standard that decreases energy used for heating and cooling by up to 90%. While the standard spread quickly in Europe (by 2010, the continent had 25,000 Passivhaus-rated structures), the U.S. has been slow to adopt the standard. Only about 100 Passive House projects exist across the country.

REACH Community Development continues its affordable home-building program with the launch of its Orchards at Orenco project this month at Hillsboro’s Orenco Station.
REACH, a nonprofit with nearly 1,900 units of affordable housing, is beginning construction of the 57-unit first phase of Orchards at Orenco, a three-building complex that will eventually provide about 150 units affordable housing. Phase 1 will serve families earning 50 percent or less of the area median family income, or about $30,000.
The project is designed by William Wilson Architects and Ankrom Moisan Architects; and Green Hammer is the Passive House Consultant.
The $14.5 million project is financed with $9 million in tax credits purchased by Wells Fargo Bank, a $2.4 million permanent loan with Oregon state credits and contributions from the Washington County, Meyer Memorial Trust, Energy Trust of Oregon and NeighborWorks America.
Key Passive House features include:
- The roof will have 12 inches of insulation, about four times what is required. The light color will reflect solar radiation and help moderate the building temperature.
- PVC-fiberglass hybrid windows will have argon-filled triple pane glazing and are designed to close tighter than more common models.
- The building is positioned to keep the building comfortable in summer months with shading devices that allow winter sun but block it in the summer.
- The building’s super-insulated envelope includes four inches of foam insulation under the ground floor slab.
