Case Study #4: S.T. Olin Lab
Scope of Work
· Recommissioned the existing mechanical and control systems to optimize overall system performance.
-
Installed PIR occupancy sensors to reduce excessive air change rates and enable occupied and unoccupied modes of operation.
-
Rebuilt the existing air handling humidification units to improve system efficiency while minimizing energy use.
-
Installed fume hood closed mode to reduce ventilation rates when rooms are unoccupied with fume hoods closed.
-
Installed VSDs on the laboratory building exhaust fans to provide better static pressure control.
