After investigating current facility operations and equipment, we recommended five energy-reducing strategies. Our team implemented upgrades to the BAS, optimized air handling unit (AHU) controls, replaced AHU dampers, installed and programmed variable frequency drives, and optimized chilled and condenser water system stages and operations. Working with hospital facility management, we determined critical areas that require constant air flow and placed hundreds of terminal units and dozens of AHUs on customized schedules or overnight setback, programmed occupant overrides, standardized and optimized AHU economizer sequences, and set supply air temperature points for AHUs under a reset schedule based on outside or return temperatures.

Following construction, we scheduled a measurement and verification (M&V) period to track energy savings so utility incentives could be disbursed, further reducing simple payback.
