This engineering-led energy savings performance contract involved major infrastructure upgrades across three hospital campuses. Work included replacing and installing: 3 constant-speed water-cooled chillers (3,400 tons)
4 variable-speed water-cooled chillers (4,000 tons)
2 heat recovery chillers (350 tons)
9 cooling towers (24,000 tons)
600 HP steam boiler with stack and blowdown economizers
Steam-to-hot water heat exchangers
30 pumps, 137 VFDs, and 2 desiccant AHUs District heating water piping was rerouted to multiple building entrances, replacing outdated remote shell-and-tube heat exchangers and pumps. Main steam distribution piping was pulled back to a central plant with new flash tank, condensate receiver, and economizers. All work was completed while hospitals remained fully operational. The team developed phased design packages to maintain continuous delivery of steam, heating water, chilled water, and power, avoiding unplanned shutdowns. * Experience of Paul Sabal while at a previous firm. * Experience prior to joining HFA.
