Open Doors Abound for

International Passive House Open Days

A Global Celebration of High Performance Building

This weekend, buildings across the country will open their doors, joining one of the largest open house events in the world. International Passive House Open Days is an annual event that aims to educate the public about Passive House building standards.

Passive House is a design and construction standard that drastically reduces building energy use and carbon emissions, but those emissions reductions don’t come at the cost of a chilly office or a stuffy den. Passive House prioritizes occupant comfort and health, creating built environments with stable temperatures, controlled humidity, and acoustic calm. The unparalleled comfort that a Passive House offers is something best experienced in person. It’s why over 20 projects across the country are holding open hours and tours during the three-day event.

This year’s event features projects in 9 states, including 7 projects in California, 4 in Colorado, and 4 in New York, where Sendero Verde, the largest multifamily residential Passive House in the country, will be open for tours for the first time in partnership with Green Home NYC. Open Days events will also be held in Connecticut, Massachusetts, Minnesota, Montana, New Jersey, and Pennsylvania. You can see the full list of locations and RSVP for an Open Days event near you here.

It’s the largest Open Days event held by The Passive House Network to date. To celebrate the growing movement, we’ll be raffling off two PHN T-Shirts each day of the event to those who share their visits on social media. Post a photo of your visit on LinkedIn or Instagram and tag us to enter!

As much of the country navigates another wave of extreme temperatures, we hope this weekend you’ll be able to visit a Passive House near you and get a reprieve from the heat. Once you step inside, you’ll understand why Passive House building standards result in safe, comfortable, energy-efficient buildings.
