Eight Story Office building in Richmond, Va. Reduces energy by installing VFDs

Cii reduced energy usage by installing VFDs on two main air handling units and two return air fans. The total motor horse power was 330. The old system of inlet guide vanes was used to control static pressure.  Cii ran the energy savings predictor software for VFDs and found over 60% Kwh savings by going to a VFD system for control. It is predicted to have a payback of 2.2 years with an estimated savings of $21,950.00 per year.

Also the building owner for this project received a rebate check from Dominion Virginia Power in the amount of $12,210.00 thru the HVAC Rewards Program.
