Spring and Summer Energy Saving Tips
- Insulate your attic and caulk and weather strip doors and windows to prevent warm air from leaking into your home.
- Use a ceiling fan, which will allow you to raise the thermostat setting about 4 degrees without impacting your comfort.
- Install a programmable thermostat, which could help you save up to 10 percent on heating and cooling costs each year.
- Operate your thermostat efficiently by setting it as high as possible in the summer.
- On hot days, consider using an outdoor grill instead of your oven.
- Schedule regular maintenance on your cooling system to keep it running efficiently.
- Install energy-efficient window coverings that let natural light in and prevent solar heat gain.
- If you do need to replace your air conditioner, buy an Energy Star-qualified unit, which are up to 15 percent more efficient than standard models.
Setting your Thermostat Saves Energy
Naperville residents can save as much as 10 percent a year on heating and cooling by simply turning their thermostats back 7° to 10°F for eight hours a day from its normal setting. The percentage of savings from setback is greater for buildings in milder climates than for those in more severe climates.
You can easily save energy in the winter by setting the thermostat to 68°F while you're awake and setting it lower while you're asleep or away from home. In the summer, you can follow the same strategy with central air conditioning by keeping your house warmer than normal when you are away, and setting the thermostat to 78°F (26°C) only when you are at home and need cooling. Set your thermostat at as high a temperature as comfortably possible and ensure humidity control if needed. The smaller the difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.
Although thermostats can be adjusted manually, programmable thermostats will avoid any discomfort by returning temperatures to normal before you wake or return home.
