The Sidwell Friends School may be the nation’s most environmentally friendly school. Committed to environmental stewardship, Sidwell directed architect KiernanTimberlake to design a sustainable middle school. The design uses daylight as the foundation of its strategy to minimize energy use. For the school’s southern exposure reflective C/S Lightshelves are attached to the exterior 4-1/2’ deep C/S Cantilevered Sunshades with 6” airfoil blade. The sunshades and lightshelves reduce heat and glare while allowing light to enter.
