Welcome to Passive House Northwest!

PHnw is a community of Certified Passive House Consultants and others involved with high-performance building. Our goal is to promote highly energy efficient construction through implementation of the passive house concept. We are motivated by the long-term protection of the environment and climate; the promotion of sustainability, quality, and durability in building construction; the creation of a built environment that is healthy for its inhabitants; and the advancement of energy independence and the reduction of operating costs for building occupants and owners.

Passive House is the world's leading standard for energy efficient construction. It combines building enclosure efficiency and passive solar strategies in a system for designing and building cost effective, comfortable, energy efficient buildings. Its effectiveness has been demonstrated in projects in every climate zone around the world, ranging from single family homes to very large commercial and institutional structures. More than 50,000 examples have been completed worldwide.
