CARTER SCOTT  Builds zero energy & positive energy  homes.

Carter Scott designs super insulated net-zero and positive energy detached houses in Massachusetts with Mitsubishi mini-splits, Navien instant water heaters and solar panels. He says solar PV now costs just 80 cents per watt. A few homes came with enough panels to power the house and an electric car for 30,000 miles. He’s working on more than 100 net-zero or better homes that cost just $1.40 per square foot to build. Photo: Transformations Inc.
