Yale’s Chemistry Research Building consolidates fume-hood-intensive organic chemistry research activities into one building and accommodates changes anticipated to occur throughout the building’s lifespan. Primary objectives included horizontal and vertical flexibility within the program, functional relationships and laboratory systems, and modularity, flexibility, and adaptability in laboratory planning, building structure, and building system design. With 160 eight-foot chemical fume hoods, 74 point-exhaust systems, 37 vented storage cabinets, 37 equipment exhaust locations, and a once-through cascade air system serving the entire building, the CRB required innovative measures to mitigate its potentially tremendous energy consumption. Design solutions included combination vertical and horizontal fume-hood sashes to reduce airflow; placement of valves outside rather than inside hoods; and zone presence sensors that decrease rates of hood exhaust when researchers are absent. Recipient of a LEED Silver rating, the project exemplifies environmentally responsible design.
