Creating Efficient, Healthy Buildings

The Phius Alliance Cascadia chapter provides a robust membership-based network for passive building professionals in Washington, Oregon and Idaho.

The climate-specific Phius standards are the only passive building standards proven to perform in all seven climate zones found throughout the United States. Our mission is to create healthier, more efficient buildings through education, training and advocacy for the Phius passive building standards and make them the mainstream standards of building for our future.

We are inclusive of all professionals engaged in the design, construction, and testing of high-performance buildings regardless of the origin of their certifications and we value the contributions of each individual. We create a culture of collaboration and sharing throughout our membership base and collectively contribute to the advancement of the passive building methods through our work.
