A few keys to an energy-efficient basement are:
- Insulation: most newer basements have insulated walls. Few have insulation in the ceiling. Ceiling insulation is a thermal envelope to keep heat in the basement and has the added benefit of acting as a sound dampener. The only downside is that it is relatively expensive.
- LED lighting: the yearly cost is pennies per fixture.
- Instant water heater: They’re somewhat expensive and require regular maintenance, but they are much more efficient than standard water heaters.
- Energy efficient heating and air conditioning: this is a standard feature for newer homes. For an older home, this may be a great way to make your house much more energy efficient.
