Energy Efficiency Auditing questions, answered by experts

Insulation is measured by R-value, which is the measure of a material's ability to resist heat transfer. The higher the number, the better the insulation. When installing insulation yourself, you need to determine the optimal R-value you need to keep your home warm in the wintertime, cool in the heat of summer, and energy-efficient all year long. Each inch of insulation provides between a 3 and an 8 R-value. The climate where you live plays a major role in what R-value you need and the price tag you might see in your insulation installation.

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.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Audits typically take 2-4 hours, depending on the property size and energy systems.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.
