Accoya wood was selected for the Squirrel Hill Passive House in Pittsburgh. Homeowner Lucyna de Barbaro chose the rich, reddish-brown stained Accoya wood exterior. She says, “We have a huge specialty here. It’s a unique house with a high level of detailing that went into it. … It’s stunning.” The duplex is the first certified passive house in Squirrel Hill and one of just half a dozen in the Pittsburgh area, notes lead architect Erik Fritzberg of Dunn and Associates, who estimates the abode’s heat recovery and ventilation systems will be 92 percent efficient and that the house will use about as much energy as a hair dryer to heat and cool.
