Lighting Design Alliance transformed what was once an auto parts warehouse into a luminous showcase for energy-efficient lighting design. Designed to meet LEED Platinum, daylight harvesting and dynamic dimming coupled with 10kW of photovoltaic panels on the roof reduce the lighting load to 0.07W per square foot. On the main façade, vertical louvers block west-facing light during the day but still allow ample natural light into the front office. Metal halide downlights illuminate the office entrance at night, while linear LED lightbars graze the textured stone surfaces (far left). The conference room (top right), is illuminated with natural light thanks to a full-height window wall. But at night the space is supplemented with a variety of electric sources—including color-changing LED covelights, direct-indirect fluorescent pendants, MR16 downlights, and compact fluorescent wallwashers—which are all dimmed separately with multiscene presets. In the work area (bottom right), concealed linear T5HO fixtures in clerestories provide general lighting. All the fixtures dim and are connected to photo cells, occupancy sensors, and a time clock. The skylights are tripled glazed for thermal heat gain and a clear north-facing window allows for full sky view. The 4-foot-by-4-foot skylights are equipped with suntracking mirrors and energy modeling software tracks energy savings.
