“Minimizing energy use is one of the simplest and most effective means of addressing the important challenges of operating costs and the University’s commitment to reducing greenhouse gas emissions. Energy conservation requires no installation, no labor, no upkeep and results in immediate cost and greenhouse gas savings”  Dean of Administration, Francis X. McCrossan

Harvard Law School joined the Faculty of Arts and Sciences in adopting a temperature policy in May 2009, which was instrumental in leading the University to commit to a University-wide Temperature Policy in July 2009.  The HLS Facilities Management Office oversees the implementation of the policy, heating, or cooling buildings to temperatures within seasonal ranges:

  • In cold weather (October 16 – May 14), buildings are heated to 70° F
  • In warm weather (May 15 – October 15), buildings in which air conditioning equipment exists are cooled to 74° F

“These temperatures were chosen because we believe them to be within a range of comfort for individuals in seasonally appropriate clothing.  In addition, we expect that each year these minor adjustments will help us save $60,000 and reduce our greenhouse gas emissions by 115 MTCDE (metric tons of carbon dioxide equivalents).” Dean of Administration, Francis X. McCrossan

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 can’t find what you’re looking for, contact Facilities Management at facmgmt@law.harvard.edu or 617-495-5521.

Areeda and Langdell Halls

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 fan operation.  Leaving this tab at “AUTO” is recommended; it automatically sets 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 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 bottom right of the thermostat to initiate a two hour override period.  After pressing the override button, adjust dial and fan speed.

Austin and Hauser Halls

thermostats

General Information

Flip open the thermostat cover [far left photo].  Move the sliding bar on the left up or down to raise or lower desired temperature [middle left photo].  Slide bars all the way to the top if you’d like to heat your space to the highest temperature within 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 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 a desired setpoint, but correspond to the current actual temperature reading in the room.

The fan speed 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 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/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 slide bar and fan speed.

23 Everett Street

General Information

Thermostats and fan speed controls are generally located on top of HVAC units in each office and in hallways.  In some locations thermostats can be found on walls, separate from HVAC unit (fan speed) controls.

After Hours/Weekends/Breaks

During the heating season (winter), occupants should lower  thermostats to “cooler” and turn fans to “LO.”  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/Holiday Overrides

If you are working after hours and need heating or cooling, press the appropriate zone override button, located in your hallway, for a two hour system override.  Adjust thermostat and fan speed as necessary.  Remember to turn fans to “LO” and reverse settings before leaving.

125 Mt. Auburn

General Information

Flip open the thermostat cover.  Move the sliding bar on the left up or down to raise or lower desired temperature.  Slide bars all the way to the top if you’d like to heat your space to the highest temperature within 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 range of our policy (74°F in summer).  Note that the numbers on the small thermometer in the middle of the panel do not line up horizontally to the sliding bar on the left.

After Hours/Weekends/Breaks

During the heating season (winter), set office/area thermostats to their lowest setting.  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/Holiday Overrides

Thirty minute override buttons are located on thermostats; press and then adjust temperature.  Remember to reverse settings before leaving.

Gannett House

General Information

Thermostats in Gannett House automatically maintain space temperature set points as defined by the HLS Temperature Policy.  Fans are also automatically controlled to maintain the space temperature setpoint and will shut off automatically when space temperatures are satisfied.

After Hours/Weekends/Breaks

Thermostats will automatically go to unoccupied setback temperatures based on an occupancy schedule or an occupancy sensor detecting presence in the office. 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/Holiday Overrides

Occupancy sensors will detect presence in the building during weekend and holiday hours and automatically activate the heating and cooling systems.  It may take a little time for space temperatures to reach setpoint.

Griswold and Pound Halls

General Information

There are a few different types of thermostats in Griswold and Pound.   Many thermostats in Griswold and Pound do not have fan speed switches.  Set thermostats to temperatures within 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/Holiday Overrides

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

Heating and cooling for Pound is available during weekend and holiday hours and occupants should set their thermostats to the desired setpoints if they are working during these hours.

Wasserstein Hall

There are two types of thermostats in WCC. Both styles of thermostats allow occupants to control their offices within the Law Schools temperature policy. Operation and description of each thermostat is below.

If your office thermostat looks like this:

Wasserstein thermostat

You may adjust the temperature within seasonal set points by using ˆ and ˇ buttons. Press > for enter.

The fan to circulate air is controlled automatically and is turned off during “Unoccupied” hours or if you window is open. The fan speed button is not applicable. You may override the fan on during off-peak hours by pressing the sun/moon button once which will adjust temperature to the occupied settings for two hours.

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.

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 room temperature to drift towards unoccupied set points when room is unoccupied.  There will be 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.

 

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.

Lewis International Legal Center

After Hours/Weekends/Breaks

Lower thermostats to 60°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.

Weekend/Holiday Overrides

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

North Hall

The thermostat must be in “auto” to control room temperature; this mode is controlled by the OFF/AUTO button.

Press the up and down arrows to select a desired room temperature, or “set point.”  Press DISPLAY to toggle between the room set point and the actual room temperature.  Adjust fan speed by pressing the FAN button; fans help circulate air.

A door mounted sensor allows the thermostat to automatically adjust settings to conserve energy when the room is empty.

HLS Apartments (1637 Massachusetts Ave., Baker, Carriage)

Press the up and down arrows to select a desired room temperature, or “set point.”  Fans must be running for room air conditioning to work.  To turn air conditioning fan on or off, press and hold the sun/moon button for 3 seconds.  There will be a 10-15 second delay before the fan turns on or off.

Air conditioning is generally available to North Hall and the HLS apartments between mid May and mid September.  However, please note that the availability of air conditioning is contingent upon outside air temperatures.  During the spring and fall when temperatures vary, If rooms or apartments are warmer than outside air, residents are expected to use windows to allow cool air into their rooms.

When away for long weekends and holiday breaks, set thermostats back to 60-64°F during the heating season, and up to 80°F during the cooling season.  Rooms will take a little time to readjust upon your return, but energy savings from conservation in this manner are substantial.
