Heat (or Chill) Bill Allocation
Design and Hardware
Some buildings are heated and cooled with natural gas baseboard heat or fancoil units. The gas bill can be allocated by calculating the amount of heat or cooling that is delivered via a thermostat setting and radiators. Fair Energy uses a Time and Temperature Meter that uses a clock (called a Runtime Clock) and a special thermal sensor to monitor the use of heat (or chilling). Eventually, heat/chill use is converted into dollars of use (see figure). In older systems, the clock was a mechanical meter that was read each month for calculations.
Fair Energy uses a state-of-the-art clock: It can tell if the zone valve is stuck in the open or closed position, if someone has tampered with the electrical connections, or if the battery needs to be replaced in its transmitter. Older systems simply told you how long the zone valve received power.

A Runtime (Heat/Chill) Submetering System: meters can be installed inside homes or in utility rooms. A single datalogger on the site collects readings from all transmitters, sometimes with the help of signal repeaters.
