Why Passive House is Here to Stay
When Dr. Wolfgang Feist completed the first Passive House in Darmstadt, Germany, in 1991, he laid the foundation for a movement that would change how we understand and implement building science forever. Since then, over 4 million square meters of buildings have been certified to Passive House Standard worldwide, and there’s more on the way. We're confident that the Passive House movement will become even stronger over the next few years. Read…
New Passive House Fact Sheets on Passipedia (free for PHCA Members)
The International Passive House Association (iPHA) and the Passive House Institute (PHI) regularly release fact sheets on topics related to Passive House design and implementation. These concise, expertly crafted documents are published on Passipedia, a comprehensive resource for Passive House knowledge. The latest publication, "Extractor Hoods in Passive House and EnerPHit Homes" (Fact Sheet #33/2024), addresses kitchen ventilation. Your Passive House California (PHCA) membership includes an International Passive House Association…
Right-Sizing Plumbing in Homes and Apartment Buildings (presented by Southern California Edison)
Description: Effective July 1, 2024, the Appendix M, Peak Water Demand Calculator (WDC) became part of the California Plumbing Code. Instead of using flow rates and flush volumes from the 1940s, the WDC will allow you to “right-size” the cold and hot water distribution systems in homes and apartment buildings using modern information about flow rates and simultaneous use. Does this sound like a snoozer? Actually, it is an environmentally responsible…
Implementing Passive House in Title 24 | California Bill Proposal
Climate Action California Needs Your Help - Together, we can make a difference! Passive House California (PHCA) is backing the Climate Action California proposal to integrate the global Passive House construction standard into California’s Energy Building Code Title 24. This move would allow the Passive House Standard to be incorporated into the code as an alternative compliance pathway, enabling the establishment of an ambitious, climate-conscious reach code. This approach represents…

“Eliminating Makeup Air: Smart Mechanical Solutions for Small Passive Homes”
In this presentation, we’ll look at recent examples of heating, ventilation, and air conditioning solutions for low-energy houses in California. The selected examples are trying to achieve cost optimization in the spirit of the original Passivhaus concept building at Kranichstein in 1991. What if the tradespeople were to build a passive house without realizing it? We’ll talk about strategies for approaching Passive performance when this is not a project goal.…
“Build it Tight and Ventilate Right: High Performance, Mechanical Ventilation with Heat Recovery” (presented by 475)
Presentation Description Building high performance buildings, up to and including Passive House certified, means we need to ‘Build Airtight and Ventilate Right’. This presentation discusses the importance and benefits of properly balanced, filtered, continuous ventilation with heat recovery in high performance projects. By using mechanical heat recovery ventilation (HRV) and energy recovery ventilation (ERV) systems to provide oxygenated fresh air to occupants, we can control how much air is brought…
Passive House: Enhancing Air Conditioning Performance (and more), Without Forcing Change | by Brian Pearson & Susan Diana Harris
I had a hand in writing an article promoting Passive House and the legislative effort we are making to get it into the CA code: California can fast-track a guideline that reliably reduces heating and cooling energy demand up to 70% below the current Title-24 baseline: Passive House. Together, we can put this climate resilience standard onto builders’ and owners’ radar, simply by adding a voluntary Passive House alternate pathway into…
