Life Science Building: Sample AHU Operating Conditions

The building is 275,000 sq. ft.  It has over 7,500 Siemens BAS points monitored, 725,000 samples per day, 4 chillers, 4 cooling towers, 12 pumps, 9 air handling units, and over 1,000 terminal units.

Sample AHU Operating Conditions

Figure below shows the base and post operation of the 3 main AHUs in the building.  Prior to the modifications, all 3 AHU supply fans were pegged at 100% speed, the air change per hour (ACH) rates were over 15 in many labs and the building initially had an energy intensity of 366 kBTU/sq. ft./yr.
