Reducing Cost of Commercial HVAC
I'm trying to reduce my church's utility bill.
Our HVAC works in four zones of 1500 square feet each. Two of the zones are the sanctuary, two are offices. We get a bill for each. The sanctuary zones cost us around $250 each, the office zones $130. They keep the air on 68 except Saturday night they turn it to 60 so that it will be cooler for Sunday. It's always freezing cold when the building is in light use, and burning up hot when it's full of people.
It's a storefront-type building with acoustical tile ceilings that are 10' in most places, 8' in the offices, and 15' in the tallest part of the sanctuary.
Any suggestions?
