2025 Passive House Symposium

We appreciate everyone—sponsors, members, speakers, volunteers, vendors, and attendees—who made this Symposium our best-attended event yet. We had a sold-out venue and the maximum number of exhibition tables. Without your contributions of resources, time, and information, we couldn’t have made this happen. We hope you had a great time and will join us again next year!

We’re always looking to improve: share your thoughts with our feedback form.

This event was approved for 6 AIA LU/HSW Credits, 6 Phius Credits, and 8 PHI Credits. Get your credits by filling out the form at phmass.org/ceu.

Note: we can only send credits to people who signed in at the event. If you attended but somehow missed signing in, email us at education@phmass.org to sort things out.

Our speakers have generously agreed to make their presentations available as PDFs. You can view the presentations in this folder.

We had a photographer (Mike Ritter) on site between 8:30am and 12:30pm. You can view his photos (and share them on Social Media) in this media drive using the password Attendee_PH_Symp. Please credit Mike Ritter/PHMass.

We would also love to get any photos you took of the event, which you can upload and view in this Google Drive.
