As homes are built or remodeled, making sure they are energy efficient is usually a top priority. While choosing traditional products that use less energy is an obvious solution, brand-new technologies have emerged that increase efficiency even more. Advanced fresh air systems are a great example. These systems pump fresh air into the home and simultaneously pull air from the inside of the home.

Dean Gamble, writing for our sister site Builder, says that “if it’s winter and the air inside your house is warm, then this heat gets transferred to the cold incoming air to heat it up. Pumping this heat from one airstream to the other is a lot more energy efficient than generating that heat from scratch.”
