This 1924 Colonial home had fallen into severe disrepair before coming up for sale. As part of the muchneeded renovation, the new homeowners (two Steven Winter Associates, Inc. employees) wanted to eliminate onsite combustion and produce as much of their operating electricity as possible. Other goals included lower embodied energy materials and a healthy indoor environment. LEED v4.1 for Homes offered one platform to address energy, health, and materials. The home was gutted down to the foundation, framing, and floors before the year-long renovation. After the first 8 months of occupancy (July-February), the home produced 14% more energy than it consumed.
