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.

R-value is a measurement that dictates how much resistance an insulation material has against heat flow—or how well it can stop heat from coming and going. A higher R-value, which is attributed to thicker and more dense materials, means the better the insulation performs. There is not one universal recommended value. It depends on climate zones. For example, Alaska, which has a naturally cold and arctic climate, has higher R-value recommendations than the hot and humid Hawaii.

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.

Audits include inspecting insulation, HVAC systems, windows, and appliances to identify energy inefficiencies.

HVAC systems use the most household electricity. This major and essential system is responsible for heating and cooling your home all year round. Since they operate for a significant amount during the day, it consumes more energy than other appliances.
