Orange County 9 Effective: (date) Attachment 2, Heating and Air Conditioning Standards Except as otherwise noted, temperature set points are based oh the standards (Attachment) of the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) and are as follows: '~, Cooling Season Set Points 75° F - 78° F ', Heating Season Set Points 68° F - 72° F Occupied air conditioning temperature settings are not set below 75 degrees and heating settings are not set above 72 degree, except for operations which require other settings based on function such as Health Department examination rooms, medical laboratories, computer equipment rooms, library stacks, recreation roams, animal quarters or the like. 3. Use of Windows Windows are to be kept closed because open windows throw the HVAC system off balance, and interfere with providing uniform heating or ccoling in large buildings. 4. Auxiliary Heating and Cooling Sources Personal portable space heaters are not allowed because of their excessive energy consumption, fire code and safety issues, If a room is not consistently within the heating/air conditioning set-point range, Public Works shculd be notified so that the problem can be addressed. If building conditions are such that acceptable temperatures cannot be achieved by the HVAC system, Public works takes necessary measures to resolve/rectify, If auxiliary heating or fans are required, Public Works will provide these, 5. Night, Weekend and Holiday Temperature Set-backs The heating temperatures are set to 60 degrees for all buildings for periods when buildings are not normally occupied. The air conditioning temperatures are set to 80 degrees when buildings are not normally occupied. Normal occupancy for most buildings is from 7:30 a,m. to 6:00 p,m, This means that from 7:30 a.m., until 6:00 p,m,, the temperature will be within the set points defined in Item H2 above. Note: Exceptions to the set backs are made for those functions that must remain operational during these periods such as for night meetings, Emergency Management or the .Jail. Also some buildings have unique requirements far longer start up times to reach heating or cooling set points. If a building has complete digital cantrcl, and individual zone or office temperature control, occupants will be able to override the schedule to provide heating/cooling for their office at any time, for a limited period (typically two hour intervals).
