Bench marking /Performance Measurement The Energy GE)Rs°ry ti°n MaRa vnrConservation Management Team uses reporting information to benchmark and measure performance: • From year -to -year (aggregate and by individual building) adjusted for heat and cooling degree days, humidity l°" °' and the 10keand any other significant factors, in keeping with accepted industry practices, and • Compared to results for organizations located in similar geographic areas. H. Energy Use Standards 1. General The intent of the energy and water conservation policy and program is to achieve reductions in energy and water consumption while maintaining reasonable comfort levels for building occupants. Initial temperature set points were based upon ASHRAE comfort chart for 50 percent relative humidity, and employees at light work. 2. Heating and Air Conditioning Standards Except as otherwise noted, temperature set points are based on 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 degrees, except for operations which require other settings based on function such as Health Department examination rooms, medical laboratories, computer equipment rooms, library stacks, recreation rooms, animal quarters or the like. 3. Use of Windows Windows are to be kept closed, unless specifically authorized such as when the HVAC system is disengaged, because open windows throw the HVAC system off balance, and interfere with providing uniform heating or cooling in large buildings.
