Energy Efficiency

Energy consumption accounts for roughly 30% of a commercial building's operating cost and is the single largest controllable cost of operations. By taking action to improve energy efficiency can result in significant returns for building and business owners. It is common to see a 30% reduction in energy cost when a company implements the most basic of energy efficiency initiatives. Improved energy efficiency means a higher ROI. In addition, an energy efficient building creates a more comfortable working environment and leads to increased productivity.


  • Turn off lights when not needed. For example, turning off fluorescent lights saves energy, extends overall lamp life and reduces replacement costs.
  • Reduce or replace inefficient, outdated or excessive lighting within your building.
  • 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

  • Establish a preventative maintenance program for your heating, venting and air conditioning (HVAC) equipment and systems.
  • Change or clean all air filters, every month.
  • Clean all heat exchanger surfaces, water and refrigerant coils, condensers and evaporators.
  • Repair leaks in piping, air ducts, coils and fittings at the unit(s).
  • Replace defective equipment insulation, ducting and piping.

Temperature Control

  • In winter, set thermostats between 65 and 68 during business hours, and 60 to 65 during unoccupied hours.
  • In summer, set thermostats between 78 and 80 during business hours, and above 80 during unoccupied hours.
  • Adjust thermostats higher when cooling and lower when heating an occupied building or unoccupied areas within a building.
  • 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.
  • When purchasing new office equipment, look for ENERGY STAR.
  • Install plug load controllers in cubicles to control multiple loads like monitors, task lights and fans.
