During the planning phase, GBA performed detailed investigation and functional performance testing of 59 air-handling units. Identified savings measures included the following:
- Removing inlet guide vanes (IGVs)
- Installing variable fan drives (VFDs)
- Equipment operation scheduling
- Supply air temperature (SAT) reset
- Static pressure relief
Identified savings include the following:
- 4,058,526 kWh in potential electric savings were identified, which is the equivalent of $267,886 savings annually
- 320,333 therms in potential natural gas savings were identified, which is the equivalent of $185,796 savings annually
The identified energy savings represent a total facility cost savings opportunity of 8%, for an estimated simple payback of 1.59 years.
