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

Building-Specific Thermostats

Thermostat ranges are set in support of the Harvard University Temperature Policy. Find your building below for more information about thermostat operation, after-hours energy conservation, and after-hours overrides. If you cannot find what you are looking for, contact Facilities Management at facmgmt@law.harvard.edu or 617-495-5521.

Areeda Hall

General Information

Turning the dial to the right increases room temperature; turning it to the left decreases temperature. The sliding tab on the bottom of the thermostat panel controls the fan operation. Leaving this tab at “AUTO” is recommended; it automatically sets the fan speed to maximize energy efficiency. The fan may also be set to “OFF,” “LO,” “MED,” or “HI.” The red LED light on the bottom right of the thermostat should be on during normal business hours.

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 and 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.

Austin Hall

General Information

Flip open the thermostat cover. Move the sliding bar on the left up or down to raise or lower the desired temperature. Slide bars all the way to the top if you’d like to heat your space to the highest temperature within the range of the HLS Temperature policy (70°F in winter). Slide it all the way down if you’d like to cool it to the lowest temperature within the range of our policy (74°F in summer). Note that the numbers on the small thermometer in the middle of the panel do not represent the desired setpoint, but correspond to the actual current temperature reading in the room.

The fan speed control dial will be located either near the thermostat or on the HVAC unit itself. If your room is not reaching its set point, try increasing the unit fan speed by moving the control dial. Note that even fans labeled “Air Conditioner” (as above) also circulate warm air and must be used in the winter to achieve full heating.

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 slide the temperature bars down to the very bottom during the heating season (winter) and all the way to the top during the cooling season (summer) as well as turn the fan speed to “OFF.” Rooms will take a little time to adjust back to workday set points in the morning, but energy savings from conservation in this manner are substantial.

Weekend and Holiday Overrides

If you are working after hours and need heating or cooling, press the override button on the bottom right corner of the thermostat panel for a two-hour override. After pressing the override button, adjust the slide bar and fan speed.

Gannett House

Griswold Hall

General Information

There are a few different types of thermostats in Griswold Hall. Many thermostats in Griswold Hall do not have fan speed switches. Set thermostats to temperatures within a range of the HLS Temperature Policy (70 °F during cold weather, 74°F during warm weather).

After-hours, Weekends, Breaks

During the heating season (winter), occupants should set room/area thermostats to 60°F. During the cooling season (summer), occupants should set room/area thermostats to 80°F. Rooms will take a little time to adjust back to workday set points in the morning, but energy savings from conservation in this manner are substantial. Rooms with the thermostats shown in the far right image will set back automatically; no action by occupants is required.

Weekend and Holiday Overrides

Occupants of Griswold should view this attachment for instructions on overriding and activating their thermostats during the weekend and holiday hours.

Hauser Hall

Thermostat Information

Our sustainability-informed thermostat policy allows users to cool your space to no lower than 74 degrees in the summer and heat to no more than 72 degrees in the winter. The thermostat on the wall will not allow a set-point beyond these thresholds. To adjust the temperature setpoint, touch or hold the second button from the top on either side to raise and lower the setpoint.

The fan, heating, and cooling components inside an HVAC unit all control automatically to meet the space temperature setpoint. A fan may cycle through multiple speeds or turn off while maintaining room temperature setpoint.

When a space is not occupied for an extended period of time, the temperature will set back automatically to reduce energy consumption and reduce greenhouse gas emissions. Please allow time for your office to respond to the occupied temperature settings after returning from an

extended absence.

Thermostats are sometimes shared between multiple rooms and spaces. Wall devices are either SENSING ONLY or the Thermostat for a shared HVAC unit. SENSING ONLY devices are labeled. If you have a sensor in your area, know where the shared thermostat is located. Please be neighborly and communicate about your thermal comfort preferences. You have the benefit of operable windows, but when the window is open, the HVAC system in the immediate and shared area will shut down so as not to waste energy.

After-hours, Weekends, Breaks

The standard operating hours for Hauser Hall are Monday through Friday, 7 AM until 7 PM. The heating and cooling systems will typically work during the operating hours. If building users are occupying their space outside of the operating hours, they can use the “Off-Hours Override” to enable the HVAC systems. Just press the button located to the right of the person next to a box. The person will appear inside the box, and the HVAC systems will typically run for 2 hours. After 2 hours, the occupant will need to press this button again to allow the HVAC systems to operate for an additional 2 hours. This override does not function during regular operating hours.

Green Leaf User Feedback

At the top right corner of the thermostats is a LEAF, illuminated either GREEN or RED. This feature provides feedback to the occupant about the energy  efficiency of their temperature set point. While the system allows for a seasonal range of temperatures, occupants can reduce energy consumption  by lowering in the winter and raising in the summer. Harvard Law School encourages occupants to reduce their environmental footprint and join the University-wide effort to be fossil fuel-neutral by 2026.

The fan to circulate air is controlled automatically and is turned off during “Unoccupied” hours or if your window is open. The fan speed button is not applicable.

If your thermostat looks like this:

You may adjust the temperature within seasonal set points by using the temperature slide.

The fan to circulate air comes from the main air handling units. These fans automatically control during building hours.

Note for Offices with Operable Windows

Your office heating and cooling system is connected to your windows and will not operate when windows are open. Make sure your window is closed and latched to activate the magnetic sensor, which will enable proper temperature control functioning.

After-hours, Weekends, Breaks

One of the building’s energy-efficiency technologies is occupancy sensors in all offices that perform lighting and temperature energy efficiency functions.

Occupancy sensors activate heating/cooling to turn on when you enter the room and allow the room temperature to drift towards unoccupied setpoints when a room is unoccupied. There will be a brief delay between entering the room and hearing the unit switch on. After being out of the office for an extended period of time, please be patient; upon your return, it will take a few minutes for your space to warm up or cool down.

Weekend and Holiday Overrides

Occupants should contact Facilities Management at 617-495-5521.
