bioclimatic design

Portland’s climate, with its very cold winters and sometimes hot summers, requires a careful mix of active and passive design strategies to ensure proper interior conditioning. Site restrictions require the structure to be elongated along a northeast-southwest axis. High-performance, low-e, argon-filled, triple-glazed tilt-turn windows in all rooms provide cross-ventilation throughout the house. A centrally located staircase functions as a thermal chimney, allowing warmer air on the main level to escape through operable windows at the upper floor. The large southeast overhang and brise-soleil will minimize solar heat gains in the summer while harnessing the sun’s power in the winter.  Fewer, smaller windows on the northeast and northwest walls will minimize heat loss in the winter and unwanted solar gain in the summer months.
