I saw your messages from 2005 on HVAC-TALK and wanted to know if you had any more recent experience with submetering. I'm looking for a way to lower fuel costs for exhisting Multi-family properties.
I develope/convert Multi-family buildings, as apartments and condos. Some of my buildings have one hot water boiler with thermostats and Taco zone valves in every unit.
I've searched the web and found equipment and billing companies on the East and West coasts, but none in the Chicago area. There is one company in Ohio that sells a system that meters the zone valve and sends the information to a billing company. The billing company computes the BTU's used by each apartment and send out the bill.
Have you put in other submeter systems, besides the one in 2005?
Do you know of any suppliers/installers in the Chicago area?
