McKenney’s dramatically improved energy efficiency at a corporatecampus in Atlanta, following an HVAC system and controls retrocommissioning.

The ChallengeThe system and older pneumatic controls were not functioning properly, and as a result, occupants were uncomfortable and they were consuming too much energy. Air compressors ran constantly due to leaks, several chilled water valves were not calibrated correctlyand a variable frequency drive (VFD) on one air handling unit was running in bypass. In addition, the building owner did not have aclear understanding of occupancy schedules.

The SolutionThe team repaired and replaced major leaks throughout the compressed air system, cutting run time in half and raising the airpressure to an acceptable level. Leaking chilled water valves were fixed, faulty VFD wiring was repaired and pneumatic controls,stats and sensors were recalibrated. The team also set controls to shut down areas of the building that did not need 24/7 conditioning.
