U.S. projects are located in Massachusetts, New York, New Jersey, Minnesota, Colorado, Montana, Oregon, and California. Most seem to be single-family homes, but there’s also a high-rise mixed-use office building in downtown Boston on the schedule.
Times and dates vary, and registration in advance is required. A complete list of locations and times is available here. There also are virtual tours from last year’s event on a dedicated YouTube channel.
Ken Levenson, executive director of the Passive House Network, said in a press release that one aim of Open House Days is to give visitors a chance to see the houses for themselves and talk with owners. Buildings that are certified by the Passive House Institute meet strict performance guidelines, including low energy use and low rates of air leakage. But Levenson said the benefits aren’t always fully appreciated.
“People are understandably skeptical of the impressive performance claims made by Passive House practitioners, and too often supporting data leaves people unmoved,” he said. “That’s why this event is so important, so that everyone can see it and experience it for themselves, speak to building owners and get the unvarnished story, the personal story.”
Associated events include a virtual tour on November 5; attendees will see an 1879 New York City firehouse that has been retrofitted to be a residence. There is also a gathering at the 475 High Performance Building Supply offices in NYC on November 5, and a happy hour in Littleton, CO, on November 6 at the Breckenridge Brewery, hosted by Emu Passive and 475.
