International Passive House Open Days | November 13–15, 2026

Imagine a home that stays comfortable year-round, keeps the air clean, cuts your energy bills, and runs without fossil fuels. Passive House buildings do all of that, and you can tour them this fall.

Join California Passive House Open Days, part of the International Passive House Days held worldwide. Visit featured projects across the state and hear firsthand from the people who know them best: the owners and occupants who live there, and the architects, engineers, contractors, and consultants who built them.

Ask questions, see the performance data, and find out what it’s really like to live in one.
