Before making individual efficiency upgrades, it’s important to know how your home uses energy. A home energy assessment is the first step to saving energy and money.
Sometimes called an energy audit, a home energy assessment helps you learn how you use energy, determine where it’s being wasted, and prioritize efficiency upgrades. Making energy efficiency upgrades identified in a home energy assessment can save 5-30 percent on your monthly energy bill while also ensuring the health and safety of your house.
During a professional energy assessment, an energy assessor analyzes your energy bills, completes visual, health and safety inspections, and may use special equipment -- such as a blower door and an infrared camera -- to detect sources of energy loss. The Energy Saver 101 home energy assessment infographic gives you an idea of what energy assessors look for and the special tools they use to determine where a home is wasting energy. Based on the data collected, an energy assessment will provide you with a comprehensive home energy report that shows which energy efficiency upgrades are best for your home and your potential energy savings. Learn how to find a certified energy assessor and if your state or local utility offers free or discounted home energy assessment. And be sure to look for a Home Performance with ENERGY STAR participating contractor -- they're specially trained to conduct a whole-house assessment and help you determine how efficiency improvements will work together.
While not as thorough as a professional home energy assessment, you can conduct your own simple home energy assessment. A do-it-yourself home energy assessment -- or walk through -- can help you pinpoint some of the low-hanging fruit when it comes to energy efficiency upgrades.

Remember, the home energy assessment is only the first step to cutting your energy bills. Making the recommended energy efficiency upgrades is what leads to energy savings.
