The 28,000 sf Olin Arts & Sciences Academic Building constructed in 1976 required a full HVAC
renovation. The oil fired boiler and domestic hot water storage tank were replaced with two high
efficiency condensing boilers and a high efficiency condensing domestic hot water heater. Circulating
pumps were replaced with variable frequency driven pumps.

Existing air handlers were replaced with heat recovery units and ducting was modified where required.
