Okay guys , I've been looking at this option for a 13 story office building in the Midwest .The current system is VAV , with VFD (VSD's on all air handlers) , also use some economizer , but minimum outside air on some floors is set for max load , when floors are currently only 30%- 40% full .All the case studies seem to indicate people save a ton of cash .
Our building control system is state of the art , so interfacing shouldn't be a problem . My only concern is that the CO2 sensors are notorious for drifting , losing calibration that sort of thing in a few months after installation . So some say you may end up not saving as much as expected.
Has anyone had experience with retrofit Demand control Volume ? Any issues , pitfalls before I take the leap ?
Many thanks
