International Passive House Open Days June 2023

Well, that’s a wrap. The 3-day International
Passive House Open Days was a huge success.


Organized globally by the International Passive House Association, the International Passive House Open Days came to a wrap last week, with sites open to visitors from Friday, June 23 – Sunday, June 25th. This event was a great opportunity for the public to learn about Passive House buildings of all kinds around the US and the world. Most sites had homeowners and professionals on hand with the knowledge and tools to explain the technical details of Passive House projects.

Hilary Paget of pHdesign recaps the Open Days at their Park Slope Townhouse, “Overall, we addressed some great questions and had interesting conversations. Attendees represented a cross section of industry professionals as well as people outside the industry who were generally interested in Passive House and low energy building.”

Shelby Wosick from Shape Architecture Studio added, “ Visitors mentioned being appreciative of the opportunity to learn about and see a Passive House in person. The owners enjoyed being able to talk about their home as well and the benefits they expect the Passive House features to bring once the house is finished.”

Passive House Network had twelve sites spanning across the US from New York to California, with projects ranging from single-family retrofits, to multifamily and commercial new builds, to a couple of spectacular rebuilds from the Marshall Fires in Colorado. Here is the full list of sites that opened their doors last weekend:

  • 17 Mile Haus, Pebble Beach, CA
  • Sebastopol Passive, Sebastopol, CA
  • Morongo Desert House, Morongo Valley, CA
  • Millhaus Passive, Fort Collins, CO
  • The Enclave Passive House, Louisville, CO
  • The Sunflower Sanctuary, Louisville, CO
  • Park Place Passive, Somerville, MA
  • Energy Retrofit Open House, Glen Rock, NJ
  • Park Slope Passive House, Brooklyn, NY
  • The Passive House, Hudson, NY
  • The Catskill Project, Livingston Manor, NY
  • Six & Kane, Kane, PA

“At Pebble Beach, three visitors worked at the Naval Academy and are about to embark on the design of a new Innovation Center. They were looking at Net Zero but I hope will now consider using Passive House.” Bronwyn Barry of the 17 Mile Haus explained, “I was inspired to see the broad spectrum of interest, but delighted by the students from the PHN cohort who showed up and asked great questions.”

Are you interested in showcasing one of your projects on the International Passive House Open Days? You are in luck! We will be hosting another event in November of 2023. Watch for registration details coming soon.

About PHN:

The Passive House Network (PHN), formerly known as NAPHN, is a 501(c)3 that provides Passive House high-performance building education and resources to professionals across the U.S. that transform how they think and work with buildings. PHN provides professionals a complete skill set to reliably produce new and renovated buildings that use dramatically less energy for effective and affordable climate action.

About PHI:

The Passive House Institute (PHI) is an independent research institute that has played an especially crucial role in the development of the Passive House concept – the only internationally recognized, performance-based energy standard in construction.

About Passive House:

Passive House is an international building standard and methodology, applicable to buildings of all kinds from office buildings to hospitals, new-build and renovations, that results in a dramatic drop in operational energy use, and more comfortable and healthy occupants – meant to aggressively mitigate our climate crisis while providing resilient adaptation.

The Passive House Standard was developed by the Passive House Institute (PHI), an independent scientific research organization, located in Darmstadt, Germany, and includes specific requirements for energy use and comfort of occupants. The Passive House Standard is being successfully applied to thousands of buildings and millions of square feet around the world, from Boston to Beijing.

The Passive House methodology starts with reducing cooling, dehumidification, and heating loads by focusing, not on gadgets and active technology, but instead on fully integrated durable passive building components, such as proper continuous thermal-bridge-free insulation, continuous airtightness, high-performance windows and doors, and ventilation that includes a high-efficiency heat/energy recovery core, carefully calculated, and all integrated with the entire architectural process of design and construction.

The International Passive House Association is a membership, communications, and global community-building arm of the Passive House Institute with over 30 affiliated regional Passive House organizations around the world.
