What Is the Recommended House Temperature?
The U.S. Department of Energy recommends that home temperature be set to 68 degrees Fahrenheit in the winter and 78 degrees Fahrenheit in the summer. When no one is home, adjust temperatures to cooler settings in the winter and warmer settings in the summer.
Programmable thermostats save energy by adjusting the house temperature according to the season and the occupants’ activity level. The closer the desired indoor temperature is to outdoor conditions, the less energy is needed to reach and maintain the desired setting. Consider the occupants’ age and comfort in setting temperatures. The West Midlands Public Health Observatory recommends temperatures of at least 73 degrees Fahrenheit for adults age 58 and over, and WebMD recommends setting nighttime temperatures according to individual comfort to prevent sleep problems.
