Guidelines for Improving Energy Use

Schedule an appointment with your Facilities Superintendent to discuss some of the following:

  • Make sure that thermostats and temperatures are within University guidelines of not less than 75 degrees in summer months and not more than 68 degrees in winter months during occupied hours.
  • Discuss utility “ time of day scheduling, ” building use
    • Most Yale buildings are split into zones, each controlled by its own air handler. If you need space conditioning on at a time of low occupancy (night, summer hours, etc.), consider concentrating activities in just one zone of the building, so that the majority of air handlers do not need to be in use
      • Example: A building administrator may ask that group meetings are limited to the first floor of a building during the summer, so that air conditioning does not need to be run (or is run less intensively) on other floors
      • Example: A residential college may limit use of dining hall facilities during non-meal hours, and reduce energy use for this zone
  • The Operations Center at 344 Winchester may automatically schedule your buildings’ heating/cooling based on your program use, etc. and may be able to make recommendations for building use changes that may reduce energy costs. Operations center information can be found at
  • See the energy surveys conducted by facilities for an assessment of where your building could improve its energy use

Equipment upgrades for your building:

  • Upgrade incandescent or halogen bulbs to LEDs
  • Replace any aging equipment with Energy Star and energy saver types wherever possible
  • Installing new occupancy/vacancy sensors in areas that currently have manual lighting
    • If occupancy sensors are broken, these can be fixed through a facilities work request
  • Contact your facilities superintendent to discuss updating your building’s HVAC system if you believe that it is outdated
  • Update old windows to reduce drafts

Actively encourage your staff/unit/department to proactively manage energy (for example):

  • Shut off lights in areas where occupancy sensors do not exist; request that occupancy/vacancy sensors be installed in areas that are often needlessly left on.
  • Consider relocating personnel away from drafty windows or other colder places within rooms, when possible, to make lower thermostat settings more amenable to occupants
  • Turn off computer monitors, AV equipment, fans, heaters, etc. when not in use.
  • Make sure printers/copiers go into power saver mode when sitting idle.
  • Close fume hoods in labs (where applicable), etc.
  • Discourage the use of personal heaters, etc.
