Passive House Certification

North American PHIUS+ Certification

Overview
Close More

A Passive House is a building that is primarily heated through “passive” energy gains from the occupants, light bulbs, windows, and appliances versus an “active” heating system. Originally developed in Germany as “Passivhaus” the standard represents the world’s most advanced high performance ultra low energy standard.  A Passive House also includes safeguards to ensure superior indoor air quality and comfort as well as long-term building durability.


A typical Passive House has a reduced energy consumption of 80-90% over a building built to code, and offers an attractive, cost-effective path toward Earth Advantage Net Zero or Net Zero Ready certification. These extreme energy savings can be achieved through super insulation, very limited infiltration, thermal bridge free construction techniques, and heat recovery ventilation. A typical Passive House built in the Pacific Northwest boasts R-values over 50 on all 6 sides (walls, floor, ceiling), triple pane windows, low surface-to-volume ratios, infiltration rates under .6 Air Changes/Hour @ 50 pascals, and reduces energy consumption for space conditioning (heating and cooling) by up to 90% over a building built to code.
Worldwide, over 25,000 Passive House buildings exist but the concept is relatively new to the United States. To support this exciting new movement, Earth Advantage Institute is now offering Certified Passive House Consulting through our Portland office as well as PHIUS+ Ratings for builders looking to tap into government and utility incentive programs.

How it Works:

  • Contact a Certified Passive House Consultant (CPHC) to consult on the design of the building with the Passive House Planning Package (PHPP)
  • Submit a completed PHPP along with construction details and plans for pre-certification to PHIUS (Passive House Institute US)
  • Work with a PHIUS+ Rater to document the construction process and on-site performance testing
  • The PHIUS+ Rater will submit the final results to PHIUS+ for certification
