Energy Saving Office Tips

Office Equipment

  • Turn off PCs, monitors, printers and copiers nightly and on weekends. If unable to switch off the entire computer, turn off the monitor and printer. Don't use screen savers.
  • When buying PCs, monitors, printers, fadx machines and copiers, consider buying Energy Star® models that can switch to a power-saving mode when not in use.
  • Use a laptop computer instead of a desktop computer. The laptop will consume 90 percent less energy.
  • An ink-jet printer consumes 90 percent less energy than a laser printer.

Weather-Strip, Caulk and Shade

  • Install weather-stripping around exterior doors and operable windows, and around doors between cooled and uncooled spaces.
  • Install door bottoms and thresholds to seal gaps beneath exterior doors and doors to uncooled spaces.
  • Install window treatments: shade screens, shades, awnings or overhangs.
  • If exterior treatments are not feasible, consider interior window film, insulated drapes, valances, blinds or removable insulation material.
  • Caulk cracks and gaps around windows and doors, in the building foundation and between different building materials.
  • Repair roof leaks. Insulation loses effectiveness when wet.
  • Repair and maintain weather-stripping.
  • Keep doors between cooled and uncooled spaces closed. Install automatic door closers if needed.


  • Turn off non-essential and decorative lighting, especially in unoccupied areas.
  • Replace flickering, dim and burned out lamps.
  • Clean fixtures and diffusers as often as necessary.
  • Color-code or mark light switches and circuit breakers that can be turned off when not needed.
  • Use task lighting to directly illuminate work areas.
  • Lower the height of light fixtures if possible to increase usable light.
  • Replace burned out lamps with lower wattage lamps or energy-saving lamps.
  • Replace T12 lighting systems with T8 energy efficient fixtures.
  • Install high-pressure sodium fixtures in parking lots.
  • Install time clocks or photoelectric cells to control exterior lighting, advertising sign lighting and some interior lighting.
  • Paint dark walls and ceilings with lighter colors to maximize the effect of existing light sources.
  • Use natural lighting when possible.
  • Install dimmer or occupancy switches where appropriate to lower energy use in stairwells, copy rooms and restrooms.
  • Schedule janitorial services during the day, or use a minimum number of lights when cleaning.
  • Color-code switches that should remain off when crews are cleaning.
  • Trim bushes and trees away from outdoor lighting to maximize illumination and prevent shadows.
  • Implement a group re-lamping schedule, and re-lamp at 70 percent of rated lamp life. Lamps that run longer than 70 percent of their rated life actually cost more in terms of energy use.
