You can perform a simple energy audit yourself, or have a professional energy auditor perform a more thorough audit.
If you have five minutes and your last 12 months of utility bills, use the ENERGY STAR Home Energy Yardstick to compare your home’s energy efficiency to similar homes across the country and get recommendations for energy-saving home improvements from ENERGY STAR. You will also need to enter some basic information about your home (such as zip code, age, square footage, and number of occupants). If you don’t have your bills, contact your utility for a 12-month summary.
If you are interested in getting specific recommendations for improving the efficiency of your home, consider contacting a professional Home Energy Auditor. A professional auditor can use a variety of techniques and equipment to determine the energy efficiency of your home. Thorough audits often use equipment such as blower doors, which measure the extent of leaks in the building envelope, and infrared cameras, which reveal hard-to-detect areas of air infiltration and missing insulation.
Your first step should be to contact your utility to see if they offer free or discounted energy audits to their customers. If not, you can hire a home energy professional, such as a certified Home Energy Rater, to evaluate your home’s energy efficiency.
If your heating or cooling system is over 15 years old, you can save on electric bills and improve your home’s energy efficiency by investing in new equipment. The system you choose will depend on the size of your house, amount of insulation, heating and cooling usage, and local climate. Look for systems with the ENERGY STAR® label, which meet performance requirements established by the U.S. Environmental Protection Agency
