Energy Efficiency Auditing FAQs, answered by experts

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

Yes, barndominiums are energy-efficient as long as insulation professionals properly install quality insulation, windows, and doors. Utility bills for barndo living can be up to 50% lower than those for a traditional home.  Make your barndo more energy efficient by working with contractors and HVAC professionals to strategically place windows, doors, and heating/cooling systems. 

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

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.

A whole-house humidifier can positively impact energy consumption by improving heating efficiency. During colder months, humidified air feels warmer, which allows you to lower your thermostat without sacrificing comfort. This adjustment can lead to significant energy savings as your heating system works more efficiently. However, it's important to use the humidifier judiciously, as excessive humidity could potentially strain your cooling system in warmer months.
