Haven Studio is a small demonstration home designed to educate our local community on sustainable, net-zero energy homes. Its highly insulated and air-tight building envelop, utilizing continuous timber board insulation and a quad-pane window wall, is complemented by highly-efficient HVAC equipment, including a mini-split heat pump and energy recovery ventilator. Its low energy load enables a twelve panel rooftop solar array to produce more energy, on a yearly basis, than the home consumes, with excess energy used to power an EV charger and an adjacent building.
