In many homes, energy is wasted every single day, for example, when the heat is turned on while the windows are continuously open to air out the home. Proper behavior in airing out a home saves energy, which reduces the household’s energy costs.

Proper airing out is simple: Turn the heat off, open the windows wide, let fresh air inside, and then close the windows again after about 5 minutes. A brief period of strong cross-ventilation is better than leaving the window cracked open all day.
