About PHCA

The mission of Passive House California is to educate the public about Passive House building performance standard, to help create healthy, comfortable, energy- and resource-efficient buildings and communities.

What Is Passive House?

Passive House represents today's highest energy standard, with the promise of reducing the energy consumption of buildings by up to 80% while providing superior comfort and air quality -- all at minimal additional upfront cost. When coupled with renewable energy systems, such as solar, Passive House puts true zero energy buildings within reach.



Benefits of Passive House

  • Low Energy Use: Up to 90% less heating and cooling energy use, and 60-80% overall energy savings
  • High Quality Indoor Air: Controlled ventilation for a continuous, consistent supply of fresh air
  • Comfortable Indoor Temperature: 20ºC/68ºF 
  • Operational and Construction Savings: Vastly reduced utility bills; elimination of conventional HVAC system; much smaller solar systems required to reach zero energy; durable, tight building shell for lower maintenance, etc.
  • Proven Sustainability: 40,000+ buildings worldwide, some zero and even positive energy.​

Design Approach

  • Accurate climate- and site-specific energy modeling with Passive House Planning Package (PHPP)
  • Super-insulation
  • Minimization of thermal bridges 
  • High-performance windows and doors 
  • Optimized passive solar design (solar gain in winter, shading in summer)
  • Airtight shell with mechanical heat recovery ventilation
