Chuck Reiss, a builder in northwest Vermont, had a bold plan in 2007: he wanted to build a cluster of six superinsulated homes on a 24-arce site in Hinesburg. Reiss planned to install a roof-mounted PV array on each house, with the goal of making the homes net-zero energy, or close to it.
The homes would occupy about 10 acres of the site; the remaining 14 acres would remain agricultural. For anyone interested in passive solar design, the acreage was extremely attractive; architect Rolf Kielman (TruexCullins Architects) describes the sloping site as “a south-facing bowl.” The site is within easy walking distance (via a pedestrian path) of the shops in Hinesburg village.
The project, known as South Farm, now has five homes; the sixth will be built soon. It’s been five years since the first homeowners, David and Carrie Fenn, moved in, so it’s a good time to find out how well the homes have been performing.

Each of the homes that Reiss built is a custom home; however, the homes share many similar characteristics and specifications:
