Areas to look at to improve energy efficiency in your business.


favicon-16x16 Turn off lights when not needed.

favicon-16x16 Reduce or replace inefficient, outdated or excessive lighting within your building.

favicon-16x16 When replacing old lighting equipment, choose LED fixtures and lamps. In addition to greater efficiency, LED lighting solutions may require fewer fixtures and/or fewer lamps within existing fixtures.

favicon-16x16 Ensure that light levels will remain at adequate levels before changing out technologies and/or reducing number of lamps.

favicon-16x16 Where practical, replace incandescent lamps with LED lamps

favicon-16x16 When fluorescent T-12 lamps burn out, consider retrofitting fixtures with T-8 lamps and changing from magnetic ballast to electronic.

favicon-16x16 Replace incandescent “EXIT” signs with LED signs. LEDs use about one-tenth the wattage and last 50 times longer than incandescent-lamp signs.

favicon-16x16 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, restrooms or individual offices that are not occupied continuously.

favicon-16x16 Take advantage of natural daylight: turn off or dim electric lighting when adequate sunlight is available to illuminate interior space.

favicon-16x16 Ensure outdoor lighting is off during daytime.

Heating and Cooling

favicon-16x16 Establish a preventative maintenance program for your heating, venting and air conditioning (HVAC) equipment and systems. 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, fittings. This is a major cause of lost efficiency in HVAC systems.
  • Replace defective equipment insulation, ducting and piping.

favicon-16x16 When replacing air conditioning units of five tons or greater, purchase units with a high energy efficiency ratio (EER) to reduce operating costs for the life of the unit. Ensure that a “Manual N” load calculation is performed to select a properly sized system based on your building load characteristics and specific occupancy needs.

favicon-16x16 When old motors fail, replace them with high efficiency motors. Ensure you specify the proper sized motor for the application.

favicon-16x16 Install variable speed drives (VSDs) on large motor loads, where appropriate, to further reduce energy usage.

favicon-16x16 In facilities with older chillers, consider replacing them with new, energy-efficient units that operate at or below .60 kilowatts per ton.

Temperature control

favicon-16x16 In winter, set office thermostat offices between 65 and 68 during the day/business hours, and 60 to 65 degrees during unoccupied times.

favicon-16x16 In summer, set thermostats between 78 and 80 degrees during the day/business hours, and above 80 degrees during unoccupied hours.

favicon-16x16 Install programmable thermostats that automatically adjust temperature settings based on the time of day and day of the week.

favicon-16x16 Adjust thermostats higher when cooling and lower when heating an occupied building or unoccupied areas within a building, e.g., during weekends and non-working hours.

favicon-16x16 During summer months, a savings of 2-3% can be typically be found by adjusting your thermostat setting up one degree

favicon-16x16 Consider installing locking devices on thermostats to maintain desired temperature settings.
