Energy Efficiency Auditing questions, answered by experts

To find a reputable home energy auditor, start by researching local companies that offer the service and check their reviews, methods, and certifications. The most reputable professionals are often Home Energy Professional (HEP)-certified by the Building Performance Institute (BPI). You can also consult the Department of Energy’s certified list of energy auditors or use a state licensing tool to review local guidelines and ensure you are hiring a certified professional for your area.

When installing a new furnace, it's a good time to consider other projects that can enhance your home's energy efficiency. A great first step is to get a home energy audit, which will identify areas for improvement. Common recommendations include sealing or replacing windows and adding insulation to the attic. These upgrades can help you save money on monthly utility costs. You might also consider installing a smart thermostat to make heating your home more convenient and efficient.

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.

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

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.
