For Businesses

Lighting

  • Turn off lights when not needed. 
  • Reduce or replace inefficient, outdated or excessive lighting within your building. Replace incandescent lamps with compact fluorescent lamps (CFLs). 
  • When fluorescent T-12 lamps burn out, consider retrofitting fixtures with T-8 lamps and changing from magnetic ballast to electronic.
  • Replace incandescent "EXIT" signs with LED signs. LEDs use about one-tenth the wattage and last 50 times longer than incandescent-lamp signs.
  • Install lighting occupancy sensors that automatically turn lights on or off, depending on occupancy. These sensors work well in areas such as conference rooms, break rooms or individual offices that are not occupied continuously.
  • Ensure outdoor lighting is off during daytime.

 

Heating and cooling

  • Ensure that you regularly:
    • Change or clean all air filters, preferably every month.
    • Clean all heat exchanger surfaces, water and refrigerant coils, condensers and evaporators.
    • Repair leaks in piping, air ducts, coils, and fittings.
    • Replace defective equipment insulation, ducting and piping.
  • When replacing air conditioning units of five tons or greater, purchase units with a high energy efficiency ratio (EER) of 10.5 or more to reduce operating costs for the life of the unit. 
  • Use outside air and water side-economizers for "free cooling" when outside air temperatures and conditions permit - during the spring and fall.

 

Temperature control

  • In winter, set office thermostat offices between 65 and 68 during the day/business hours, and 60 to 65 degrees during unoccupied times.
  • In summer, set thermostats between 78 and 80 degrees during the day/business hours, and above 80 degrees during unoccupied hours.
  • During summer months, adjusting your thermostat setting up one degree typically can save 2-3% on cooling costs.
  • Install programmable thermostats that automatically adjust temperature settings based on the time of day and day of the week.

 

Office equipment

  • To conserve energy and reduce internal heat gain, turn off computers, monitors, printers and copiers during non-business hours.
  • According to E-Source, using a laptop computer instead of a desk-top system can save 80-90% in electrical cost.
  • When purchasing new office equipment, look for ENERGY STAR. The ENERGY STAR office equipment program promotes energy-efficient computers, monitors, printers, fax machines, scanners, copiers and multi-function devices that automatically power down during extended inactivity. Energy saving of 50% or more is possible.
  • Install plug load controllers in cubicles to control multiple loads like monitors, task lights and fans. These devices use a motion sensor that is incorporated with a plug load surge suppressor. Inactive equipment can be shut down when the cubicle is unoccupied.
  • Specify ENERGY STAR equipment when purchasing or negotiating a contract for new vending machines. The ENERGY STAR vending machines incorporate energy efficient compressors with refrigeration and lighting controls. Efficient vending equipment can save 30-50% over older equipment.
