Hadley Residence

A new home for two, generating four times more electricity than it uses, including the "fuel" for an electric car. This house makes Net Zero look like child's play. But while the 22kW roof-mounted system is impressive, it's not all about the PV. The design features great energy savings in its careful siting to maximize passive solar considerations such as natural heating and daylighting. Roof overhangs are sized to limit direct sun in the hot summer and to invite the sun during the cold winter months. The construction contributes as well, featuring R40 cellulose-filled double-stud walls, a R50 roof system and triple glazed windows. Heating and cooling are supplied by air source heat pumps.
