Greetings,

Would anyone who has evaluated energy savings through the use of occupancy sensors controlling VAV boxes please share some experience, do's and don'ts, etc.
I believe the VAV boxes would have a minimum setback to 0% or 10% flow and possibly no reheat in the summertime. I have been trying to model this with little success. Is it possible to do using freeware or should I start constructing hourly reports. Thank you all for your assistance.

Kevin
