High Performance Manufactured Home Study (HPMH)

Northwest Green Homes was honored to be selected as a participant in the HPMH study to measure and analyze the performance of a high performance manufactured home. Partnering together with Northwest Energy Works, Inc., Fleetwood Homes and the Northwest Energy Efficiency Alliance (a non-profit consortium funded by the region's electric utilities) a prototype manufactured home was built for Toney and Karlene Raines of Chehalis, WA. The costs of the high efficiency features of their home were completely paid for by the study.

Some of the high efficiency features of their prototype home include:
High R-Value insulation: R-45 (ceiling), R-38 (floor), R-26 (wall)
High R rigid foam board exterior wall sheathing
Triple pane (U=0.22) vinyl frame windows
Hybrid Ductless Heat Pump zonal electric heating system (heating & air conditioning)
Heat Pump water heater
Energy Star rating: home and all appliances
LED & CFL lighting

The data are still being collected but the energy savings the Raines' are enjoying so far is remarkable.

* Their attached garage is a great example of how we site-build garages to match the architecture and features of the home.
