Energy Efficiency Auditing questions, answered by experts

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.

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.

Hawaii is currently rated as the most expensive state for utilities. How much are utilities for a house in Hawaii? With electricity costs in Hawaii totaling nearly 42 cents per kilowatt-hour, residents are paying more to run their households than any other residents. Electricity costs in Hawaii are so high, mostly due to the fact that most of the electricity available to residents is produced using oil that must be shipped in from other places.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.
