Introduction to Passive House Retrofits: The EnerPHit Standard (presented by PG&E Energy Centers)

Achieving the Passive House Standard in refurbishments of existing buildings is not always a realistic goal, and for such buildings, the Passive House Institute has developed the EnerPHit standard for certified energy retrofits with Passive House Components. In this webinar, trainers from the Passive House Network will discuss how the EnerPHit standard can accommodate the realities of existing old buildings, where foundations, party lines, historic preservation, cost, and other factors make a typical Passive House certification impossible. Learn how existing structures can benefit from retrofits to move a structure from a low to high-performance building. Applying the passive house standard to existing structures has its unique challenges. Through case studies of successful retrofits, see how to upgrade a building with respect to airtightness, insulation, thermal bridge reductions, high-performance windows, and ventilation, plus learn about the EnerPHit standards and process.

The Passive House Network

The Passive House Network, formerly known as NAPHN, is leading the transformation of the building industry to low-energy, high-performance Passive House design and construction. We support the widespread adoption of the international Passive House design and construction standards, building science principles, and protocols.


  • Introductions
  • Passive House principles
  • Building envelope trades
  • HVAC, plumbing & electrical trades
  • QA/QC techniques for ensuring success
  • Q&A

The objective of this course is that at the conclusion, participants will be able to:

  • Outline the five basic principles of Passive House design and how each principle contributes to the health, safety, and welfare of occupants
  • Describe why and how hygienic ventilation is an essential defining component of Passive House design and operation. And outline how the Passive House design focuses on very good energy efficiency, which results in side benefits like great occupant thermal and acoustic comfort, improved occupant health outcomes, and economic affordability
  • Outline the major Passive House tools, PHPP, DesignPH, and Therm, and provide an overview of the tools correlating with data-driven design
  • Describe how to get from where the participant is now to constructing a building adhering to the international passive house standard through applicable case studies
  • Illustrate the data-driven design process to help projects meet their comfort, durability, and climate goals
