In 2005, the Yakama Nation Housing Authority teamed with the U.S. Department of Energy’s
Building America Program to rehabilitate 25 single-family homes in its Adams View development
on the Yakama Indian Reservation. Not only have these homes achieved a total energy savings
of 47% (over the pre-retrofit homes) but the “system retrofit package” designed during this
collaboration has been applied to more homes on the reservation and has the potential to be
replicated across more than 4,300 homes built on reservations in the Northwest under the U.S.
Department of Housing and Urban Development (HUD) 1937 Housing Act.

Efficient Homes

The original homes were built to minimal energy code standards using 2×4 wood framing with R-11 batt wall insulation, R-19 batt attic insulation, and little insulation under the floor above the concrete vented crawlspace. The Yakama Housing Authority did a complete rehab, stripping out sheetrock, insulation, roofing, windows, plumbing, appliances, and heating equipment.

Building America’s CARB team worked with the Yakama Nation Housing Authority to rehabilitate 25 homes on the Yakama Indian Reservation in eastern Washington. Lessons learned are being applied to many homes across the reservation. Builder profile Yakama Nation Housing
“A number of things we learned from this project we are applying to projects today.”
Clarence Moy, Construction Manager, Yakama Nation Housing Authority With input from CARB, the Housing Authority purchased a machine for blowing in cellulose and trained staff in its use. “Now we insulate everything with blown-in cellulose,” said Moy. “Rodents don’t like it, and we can completely fill the voids in the wall cavities.”

YNHA Future Plans

Don Clem, the CARB architect from Steven Winter Associates, appreciates the collaboration and the building skill inherent in the Yakama Nation Housing Authority. He reflects on the value of this project as an example of “bringing us back to the concepts of sustainability, which is where Native Americans started.
