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!).
