Taccogna-Donough Custom Passive House
Contemporary House Exterior, Portland
After living in an earthship in New Mexico, this couple wanted a more practical, net-zero energy home for their retirement. A modest 1400sf, clerestory windows provide daylighting and passive solar heating. The house is super-insulated, per Passivhaus standards, with triple pane windows, 90% efficient heat-recovery ventilator for continuous fresh air, and a mini-split heat pump for heating when it’s needed. A single row of solar photovoltaics provide sufficient energy to make this home net zero on energy.
