Passive House Site Tour! Join me in Cushing, Maine, tomorrow (May 12) from 2-4 pm ET for a presentation and site tour of the Winchenbach-Gray Residence: https://buff.ly/WVZaXr6

Still under construction, the home has ideal solar orientation, high-quality windows, and generous insulation.

As the CPHC on the project, I was thrilled to see preliminary airtightness tests coming back well below Passive House requirements, and my energy modeling projects it will have an Energy Use Intensity (EUI) of -11 (or less!).

Want to see a Passive House in progress? Come on out to Cushing, Maine, on May 12 for a presentation and site tour: https://buff.ly/WVZaXr6

Join me, the owners, the project team, and passivhausMAINE for the ultimate peek under the hood of this exceptionally high-performing (0.04 cfm50/sf) Passive House—free for phME members and $10 for everyone else.

Because it’s still under construction, you get to see the double-stud walls, thermal bridge-free transitions, exterior taping strategy, mechanical systems, and more.

Hope to see you there!
