Conservation Tips


Small Changes Add Up

Making small changes to your energy-use habits can add up to savings.

No-Cost Tips

Save 10-25% on Energy Bills

  • Turn off lights and appliances when not in use. Don’t forget your computer.
  • In the cold months, set the thermostat to 68° during office hours, and then back to 55-68° when unoccupied.
  • In the winter, open window coverings on the sunny side of your building to take advantage of free heat from the sun. Close the coverings on cloudy days or right after the sun sets.
  • In warm months, set the thermostat to 78-80° during office hours, and 5-10° warmer at night or when unoccupied.
  • In the cooling season, close blinds and drapes during the day to keep heat out.
  • Set the water heater to 120°.
  • Close foundation vents in the winter months.
