As the temperature drops lower with the onset of winter, there are simple steps you can take to increase energy efficiency while heating your home. First, tape or affix heavy, clear plastic to the inside of your window frames to create an additional barrier against cold air. Ensure that the plastic is tightly sealed to the frame to help reduce infiltration. Next, use a programmable thermostat such as the Ecobee to set the temperature as low as is comfortable when you are home (ideally around 68°). When you are asleep or away, turn the temperature down 10–15° for eight hours. According to the Department of Energy, this small adjustment can help you save approximately 10 percent a year on heating and cooling costs.
