    What uses the most energy in small offices

    The following pie charts illustrate what small office activities use the most energy and cost the most. Space heating, cooling and ventilation, and computing account for the largest portion of energy use in offices.  Electricity end uses include (from the top, counterclockwise): 3% space heating, 16% miscellaneous, 21% computing, 6% office equipment, 3% refrigeration, 17% lighting, 24% ventilation and 9% space cooling. Natural gas end uses include (from the top, counterclockwise): 2% miscellaneous, 3% water heating and 95% space heating.

    Ways to Save

    Space Heating, Cooling and Ventilation 
    Heating and cooling equipment is one of the largest energy users in offices. By upgrading the heating and cooling equipment, your office staff will see improvements in comfort.  
    • Simple: Seal around windows and doors with new caulk and weather stripping every few years to prevent energy loss and maintain comfort. 
    • Low cost: Install programmable thermostats to reduce heating and cooling load outside of office hours. Schedule regular tuneups for air conditioners, furnaces and boilers to ensure systems are working correctly. Add insulation to ensure cool or warm air stays inside after sealing windows and doors.
    • Capital investment: Replace heating and cooling equipment with new energy-efficient equipment.

    Computing and Office Equipment
    Computing and office equipment accounts for over a quarter of an office’s monthly costs. There are several simple upgrades that can be implemented for energy savings.  
    • Simple: Manage the computer network to ensure computers go into low-power or “sleep” mode after a period of inactivity. Turn off and unplug electronic equipment when not in use to prevent unnecessary power usage. 
    • Low cost: Install advanced power strips, which detect a drop in energy usage, and turn off electronics when your staff has left for the day.
    • Capital investment: Upgrade to ENERGY STAR certified models when replacing equipment.
    LED Light Bulb gray icon
    Lighting is another large energy user for offices. Lighting alone typically costs $140 per month.
    • Simple: Turn lights off when a space is not in use.
    • Low cost: Install occupancy sensors to turn lights off for areas where lights might be left on for extended periods, despite not being occupied. Areas with good opportunity for installing occupancy sensors include bathrooms, storage areas, conference rooms and break rooms.
    • Capital investment: Replace fluorescent lights with LEDs to see savings of up to 50%! LEDs also have a longer lifespan resulting in reduced replacement costs. Replace exterior lights with LEDs to save even more.

    See how your small office compares 

    Energy Use Intensity (EUI) is a common measure used to benchmark a building’s energy use as a factor of its size. To calculate EUI for your office, total your electric bills for one year, then divide by your building’s square footage; repeat for natural gas. If the score is lower than those listed below, you are using less energy than most.
    Average EUI for Small Offices in the Midwest
    Natural Gas
    12.0 kWh/square foot
    0.35 therms/square foot
