"I hired Airtight to spray foam insulate my rim joists and add to/correct the existing insulation in my attic. Ryan conducted the free home energy audit and was very prompt in following up with an estimate. He was very honest about the work I needed done and I was incredibly pleased with him and the crew's professionalism. I highly recommend reaching out to Airtight to see where they can help you."

Energy Efficiency Auditing FAQs, answered by experts

Yes, most audits include a report with prioritized recommendations for improving energy efficiency. Confirm with your auditor.

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.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

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.
