Energy Efficiency Auditing questions, answered by experts

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

Replacing a window frame will improve your home’s energy efficiency if the old frame is cracked or damaged in a way that allows unconditioned air from the outside into your living space or if you upgrade to a more energy-efficient window frame material. Aluminum is the least energy-efficient window frame material, followed by vinyl and wood. Fiberglass and composite frames are the most energy-efficient.

As you look for the right soundproofing drywall for you, you’ll likely come across the Sound Transmission Class (STC) rating. This rating measures a building material’s ability to absorb sound. The higher the number, the better the material absorbs rather than reflects sound, reducing noise transmission. The STC rating for drywall doesn’t mean it’s for the panel itself—it refers to the STC rating for the entire wall system, including the soundproofing drywall.

A good SEER rating is between 15 and 20. However, if you want the best possible efficiency, look for HVAC units with a SEER rating higher than 21. Keep in mind that the SEER rating doesn’t mean that the unit will reach that efficiency all the time, but it does have the capacity to operate at that high of an efficiency level.

A couple of the best ways to find a reputable energy auditor is by determining whether they are HEP-certified by the Building Performance Institute (BPI). This certification will help you narrow down your list of professionals to the most qualified pros with the most relevant experience. 

You can also choose from the Department of Energy’s certified list of energy auditors or Angi’s contractor licensing tool to find pros in your area.
