Maximize Efficiency, Save Money

Heating and Air-Conditioning

  • Schedule an annual maintenance inspection of your building's heating, ventilating and air-conditioning (HVAC) system.
  • Regularly change or clean (if reusable) HVAC filters.
  • Control direct sunlight through windows, depending on the local climate, using draperies, solar screens or films, awnings or vegetation.
  • Use fans to maintain comfortable temperatures, humidity and air movement.
  • Plug leaks with weather stripping and caulking.


  • Turn off lights when not in use; do not over light.
  • Replace incandescent and older fluorescent light bulbs with ENERGY STAR qualified light fixtures, such as LEDs.
  • Install occupancy sensors in appropriate locations to automatically turn off lighting when no one is present.
  • Adjust lighting to actual needs; utilize daylight when possible.
  • Install ENERGY STAR qualified EXIT signs.

Office Equipment

  • Always buy ENERGY STAR qualified products when possible.
  • Turn off computers, copiers and other electronics and office machines when not in use. Consider utilizing a power strip to easily turn off multiple machines at once.
  • Unplug battery chargers when the batteries are fully charged or when the charger is not in use.
  • Set computers to automatically switch to sleep mode or manually turn monitors off, rather than using screen savers.

Food Service Equipment

  • Purchase ENERGY STAR qualified commercial food service equipment, such as qualified refrigerators and freezers.
  • Clean refrigerator coils twice a year and replace door gaskets if the seal is no longer air tight.
  • Service large and walk-in refrigeration systems annually.
  • Consider retrofitting existing refrigerators and display cases with anti-sweat door heater controls and variable speed evaporator fan motors and controls.
