There are various electric baseboard heaters and electric forced air heaters in this building. Electric resistance heating is very expensive and should be minimized.
The purpose of the heaters is to add to the heating of the perimeter and the stairwells when the existing air handling equipment is incapable of maintaining the required temperatures.
It is recommended that the electric heaters be equipped with local electric controls to turn them off during unoccupied times, and to turn them off when the outdoor air temperature is greater than 10°C. A commercial quality setback thermostat with an outside air thermostat can be used. Where occupant adjustability is not desirable, ensure the setback thermostat includes security lockout functions. Where vandalism or tampering are a problem, use a Honeywell T775 controller and timer, located remotely from the space sensing element.
