The Passive House (PH) building standard is the most stringent energy efficiency standard in the world. Several affordable housing authorities in the US currently or plan to include it as a sustainability option in funding applications. Achieving the stringent air tightness requirements of the PH standard requires careful coordination through all phases of design development and construction. The team from Steven Winter Associates will take you through the steps and tools necessary – including integrated design, air barrier documents, detailed site inspections, and review testing tools and protocols. They will share successes and failures from their wide experience, from three-story low-rise buildings to 33-story high-rise structures with 300+ units.
