Taccogna-Donough Custom Passive House

  • "We're thrilled with the ease and comfort of living in our new Passive House. Throughout the entire design and construction process, the Green Hammer team was consistently flexible, trustworthy and thoroughly professional." -Bob Donough


    Dundee, Oregon

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.
