UPenn Replaces the HVAC System of a Fully Occupied, Operational Chemistry Facility
Signing the American College and University Presidents’ Climate Commitment pledge is one thing, but complying with it is quite another. At the University of Pennsylvania, compliance meant renovating the HVAC systems in a 140,000-gsf chemistry research and teaching facility built in 1973. Converting the building’s constant-volume ventilation system, which provided 22 air changes per hour (ACH) 24 hours a day, to a variable-volume system providing 4 to 12 ACH would yield massive energy savings. The catch? Doing it without kicking anyone out.
