Certified Passive House Consultants Emily Doe and Aaron Swain recently presented the “Solis Condominiums: A Case Study for Multifamily Passive House Construction” webinar with the PHIUS (Passive House Institute US). Their discussion includes the top ten tips for pursuing this standard for multifamily buildings and also references case studies from their own projects.
With its enhanced building envelope, Solis, located in the Capitol Hill neighborhood of Seattle, is targeting Passive House certification, one of the most rigorous certifications for energy efficiency. Solis is multi-family housing building comprised of apartment units paired with a lush garden spaces that, upon completion, will become the largest certified Passive House building in the state. In honor of Earth Month, we’re celebrating three of the project’s most innovative sustainable features.
We were proud to be a sponsor of this year’s Passive House Northwest Conference. Once again, the logistics of Passive House for multifamily projects were validated. For a 3-5% cost premium, using industry standard assemblies, multi-family passive house projects can achieve substantial benefits. These include: superb indoor air quality that has been linked to measurable health benefits, unparalleled thermal comfort, a quiet interior, and, last but not least — ultra-energy efficiency. The typical multifamily Passive House building uses 70% less energy than a national code-compliant building and 50% less energy than a comparable Seattle building. This is doable!
