There are two basic types of energy audits: A home energy audit you can do yourself and professional energy audits. In either case, a home energy audit is the first step to assess how much energy your home consumes and to evaluate what measures you can take to make your home more energy efficient. An audit will show you problems that may, when corrected, save you significant amounts of money over time. During the audit, you can pinpoint where your house is losing energy. Audits also determine the efficiency of your home's heating and cooling systems. An audit may also show you ways to conserve hot water and electricity.
Professional Home Energy Audits
Professional energy audits are performed by trained technicians, certified to meet the requirements of California's Clean Energy Program. When performing a home energy audit, the energy auditor does a room-by-room examination of the residence, as well as a thorough analysis of past utility bills. Many professional energy audits will include a blower door test. Most will also include a thermographic scan.
