Energy Efficiency Auditing FAQs, answered by experts

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.

While some aspects of an appraisal, such as comparable properties nearby, are out of your control, there are several steps you can take to potentially increase your home's value. Make any necessary repairs and upgrades before the appraiser's visit, as they can only value what is currently part of the home, not its potential. Examples include renovating older areas, updating landscaping to boost curb appeal, and staging your home. You can also provide the appraiser with the cost of recent upgrades, which may increase your home's value by about 50% or more of what you paid for those improvements.

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.

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

The extra insulation helps reduce energy costs by minimizing drafts and temperature exchange between indoors and outdoors.
