We used the GO Logic houses as inspiration when building our house in Central VT in 2017 (self design/build)- we’re not a truly passive house but have foot thick walls and 18 inches of insulation (all cellulose) in the roof. Southern facing windows, concrete floors for the heat mass and an air exchange system. Heat source is a Woodstock Soapstone hybrid wood stove. We use 1.5 cords of wood to comfortably (72f mostly) heat the house all winter and it stays cool in the summer.

Just curious — what type of air exchange system do you have? I’ve been exploring HRV/ERV options for my home. Seems like it’s typically done during the construction phase, and less common to retrofit an existing (build in 1996) house.

Hi, I know horselifter very well, we live in the same house and have the same child. We used a LUNOS e2 HRV system. They work great, I like that they are not centralized, easy to maintain, easy to install.

Thumbs up for the Lunos system, very easy to retrofit.
