Energy Efficiency Auditing questions, answered by experts

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.

Provide utility bills and clear access to all areas of the home, including the attic and basement.

Thankfully, LED lights use less electricity than incandescent lights, meaning you won’t spend as much on utility bills by using these light strips. Each 5-meter LED light strip will cost about $3 per year on your energy bill.

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.

String lights require electricity, but not an excessive amount, especially when compared to other lighting fixtures. LED rope lights, for instance, consume around one watt per foot. Running six or seven light strings simultaneously should only cost you around $10 to $15 each month. You can save even more money by remembering to turn off your lights during daylight hours.
