University of Bridgeport – Carlson Hall

Controlled Air, Inc, replaced boilers manufactured in 1940 with 95% efficient Patterson Kelly Mach boilers. In a cost saving measure, Controlled Air, Inc. designed and installed a stainless steel flue to go through the existing chimney. A Johnson Control Facility Explorer energy management system was utilized to manage the boilers and pumps. All work had to be performed during the heating season so Controlled Air, Inc. created a temporary boiler system to manage the load while construction was underway. The University of Bridgeport received energy rebates for the installation helping to offset a portion of the purchase of the system. High efficiency boilers, energy management system, and rebates results in a quick return on investment.
