GREEN POINTS: Aldrich Hall is a 102,825-square-foot (9552-m2) classroom for Harvard Business School’s MBA program. The building completed a three-phase gut renovation in September 2006, which provided the opportunity to green the building and led to a LEED for New Construction Silver certification from the Washington, D.C.-based U.S. Green Building Council. The renovation reduced 99 percent of the existing building’s structural and envelope components. More than half of the pedestrian walkways around the building are shaded by trees to reduce the heat-island effect. Historic lighting fixtures were retrofit to minimize uplighting and improve energy efficiency. Two hybrid ZipCars in the primary parking lot encourage alternatives to single-occupant vehicle commuting. Washroom fixtures are low-flow, and all classroom spaces use demand-control ventilation, pulling in outside air based on carbon-dioxide differentials between the indoor and outdoor environments.
