The south face of Studio 804's Prescott Passive House (at left) feature louvers to mediate solar heat gain. The operable triple-pane insulated glazing behind them is part of a natural ventilation system that includes skylights on the north side. A white metal roof helps keep the house cool during spring and summer, when the sun is high in the sky, while a charred Douglas fir façade absorbs warming UV rays in fall and winter.
