Passive Cooling

For the summer months, trombe walls are covered during the day with a solar shade to prevent heat absorption and uncovered at night to promote cooling. To further promote cooling during the summer months, the building design also includes solar chimneys, or “cooling towers.” Utilizing the principle of convection, solar chimneys allow warmer, more buoyant air to move up and out of the tower as cooler, less buoyant air filters in, creating a natural current. Proper insulation, quality seals around doors and windows, and a white roof that reflects sunlight also help in maintaining interior temperatures.
