Harvard Law School was an early adopter of the Harvard Temperature Policy in 2009, which was developed and adopted by stakeholders and facilities leaders representing all of Harvard’s Schools and administrative departments. This university-wide policy provides a framework to help building managers and occupants achieve a healthy, productive, and safe working environment while reducing energy costs and greenhouse gas emissions to the lowest practicable level. The HLS Facilities Management Office oversees the implementation of the policy, heating, or cooling buildings to temperatures within seasonal ranges:

  • In cold weather (October – May), buildings are heated to 70° F
  • In warm weather (May – October), buildings in which air conditioning equipment exists are cooled to 74° F

After-Hours/Weekends/Breaks

Thermostats will automatically go to unoccupied setback temperatures based on an occupancy schedule or an occupancy sensor detecting a presence in the office. To further increase energy savings, occupants are encouraged to set their dials to “-5” during the heating season (winter) and to “+5” during the cooling season (summer) whenever they are leaving their office.

Weekend/Holiday Overrides

If you are working after hours and need heating or cooling, and the LED light is not on, press the override button on the thermostat’s bottom right to initiate a two-hour override period. After pressing the override button, adjust dial and fan speed.
