Energy Conservation 101: Get Back to Basics this School Year


It's Labor Day and you can hear the school bells ringing  ̶  welcoming teachers and students back to the classroom. In addition to reading, writing and arithmetic, energy conservation should also be on the curriculum. Not just the responsibility of the operations team and custodial staff, but everyone can help reduce energy usage and make school facilities energy efficient with a few simple activities. Not only will this effort save school districts money, which can be used for other educational needs, but a comfortable environment improves learning and productivity…after all, who wants to study in a hot building during the summer and cold building in the winter?

The nation’s approximate 17,000 K-12 school districts spend more than $6 billion annually on energy — more than is spent on computers and textbooks combined. More significantly, as much as 30% of a district’s total energy is used inefficiently or unnecessarily. Not surprisingly, the biggest energy users on school campuses are HVAC equipment and lighting, which account for approximately 70%. Coming in third place is energy consumed by computers, appliances, office equipment and other plug-in devices.

To help you get an A+ in energy conservation this school year, here is an energy conservation checklist for teachers and students:

Energy Conservation Checklist:

  • Turn off lights when not in use—lighting accounts for nearly 50% of the electric bill in most schools. This also applies to the new energy-efficient fluorescent lights.
  • Form a student energy patrol to ensure lights are out when rooms are empty (check classrooms, the cafeteria, the auditorium, etc.).
  • Have students make signs and stickers to remind people to turn off lights when they leave a room.
  • Bump up the thermostat in the hallways and keep classroom doors closed. Otherwise, the cold air runs down the hall and outside where it is wasted to the outdoors.
  • Don’t block the airflow around vents. Keep bookcases and other bulky items away from the heating and cooling units so they don’t block and/or absorb the cold (or warm) air that should be coming into the room.
  • Students should turn off monitors that will not be used for the next class period. All computer equipment should be turned off at the end of the day and on weekends (unless your network technicians specifically instruct otherwise).
  • Form a student energy patrol to make sure monitors are off when computers are not in use and to turn computers off at the end of the day.
  • Have students conduct a survey of the number of appliances in each classroom and encourage teachers to take away unneeded appliances.
  • Have students come up with a weekly energy conservation tip to share with the class.


Energy conservation can be educational and fun by getting the entire school involved!  And, energy savings add up when the entire school joins together in conservation efforts.  Schools with effective conservation programs have reported reductions of as much as 25% in utility bills. That is something to cheer about!

School Facilities Need a Summer Vacation, Too!



Ah, summer…that time of year when students rejoice and teachers breathe a sigh of relief. While classrooms are empty, hallways dark, and playgrounds quiet, this is also an ideal time to give your school facilities a much needed break. Although there is still a lot going on during the summer months, there is no doubt these are the best months for operational and energy cost reductions.

It should come as no surprise the biggest energy users on school campuses are HVAC equipment and lighting, which account for approximately 70%. Coming in third place is energy consumed by computers, appliances, office equipment and other plug-in devices.
Therefore, it makes complete sense that with much less staff and students on campus, summer is the optimum time to save energy -- and money!

For example, the New York City Department of Energy introduced the Summer Kitchen Energy Conservation pilot program in 2009 in 57 schools citywide. The program was designed to unplug (if feasible) school cafeteria refrigerators and freezers during summer break. As a result, the City reduced energy use by 100,000 kilowatt-hours and saved thousands of dollars in electrical bills. Since then, the program has been expanded to more than 600 schools.

To help you get an A+ in energy conservation this summer, here is a summer shutdown checklist for your school facilities:

Summer School Shutdown Checklist:

  1. Turn off all lights not needed for security and ensure all outside and security lights are correctly timed so that they only illuminate at night. Summer break is a good time to change lamps and clean light fixtures to improve efficiency, or to install efficient LED exit signs.
  2. Turn off and unplug computers and monitors, and any personal appliances in classrooms: Even if all appliances at your school are turned off, they are still drawing a small amount of energy. This "phantom load" is small (usually around 1-5 watts) for each individual appliance, but can quickly add up.
  3. Maintenance, Repairs and Installation of Timers and Other Energy Saving Devices: Summer break is the perfect opportunity to do a comprehensive cleaning and maintenance of school facilities. Cleaning fans, lights and refrigerator coils may seem inconsequential, but can have a significant effect on the efficiency and life of the device.
  4. Turn up the HVAC: After those floors are waxed and deep cleaning is done, shut all the blinds and set the thermostat up to 85.  
  5. Which campus uses the least energy? Pick that one for summer school programs and shut down the other ones.
  6. Schedule cleaning crews early morning or late evening when the temperature is lowest; not during the hottest hours of the day.


Even school facilities and equipment deserve a summer vacation. This may sound like a cliché, but it's true: Take care of your school buildings and they will take care of you!
