Home Energy Audit

Dramatic Cost Savings
If done right, a home energy audit can save you hundreds of dollars in energy costs annually. The U.S. Department of Energy estimates that home energy consumption can be reduced by up to 30 percent annually merely by reducing drafts inside the house. An assessment can show how to reduce energy costs even further by conserving electricity and hot water. Finally, power companies may advise installing home automation products to make controlling your home’s heating, cooling, and appliances easier and more energy efficient.
Do-It-Yourself Energy Audits
You can do a home energy audit on your own, or have a professional do it for you. With a do-it-yourself assessment, the main goal should be to identify and plug the most obvious sources of energy leaks in your home. This means looking for air leaks and undesirable air-flow under doors and windows, through electrical outlets, baseboards, switch plates, through the attic or through window and door frames. In addition, you also should look for air seepage at the point where your walls and ceiling meet, and also where the walls and the floor meet.
Locating Home Energy Leaks
As part of a do-it-yourself home energy audit, you should also check to see if you need to add more insulation in certain areas in order to reduce energy loss. The attic, especially, is a huge source of energy loss, so make sure the hatch to the attic is properly insulated. If you have an unfinished basement, see if the ceiling has at least one layer of insulation. Also, check to see if there are any openings to the exterior of the building caused by pipes, chimneys and air ducts.
Sealing and Insulating
Once you have identified all the sources of energy loss, you should seal them using either weather stripping, caulk or other appropriate material. Verify if you need to insulate your hot water pipes, water heater and furnace. Seal all cracks in walls, the foundation, and the siding, and apply weather-resistant caulking on the exterior of all doors and windows. Replace your water heater filter at least once a year to minimize energy consumption.
Professional Energy Audits
In case you do not want to do all this yourself, you can get a professional services firm to do one for you. Professional residential energy assessment services typically are able to do a much more thorough audit of your home than you would be able to do on your own. Many of them use techniques such as thermal scanning, air infiltration tests, infrared cameras, blower door tests and furnace efficiency tests to identify potential weaknesses in your home. This kind of a home energy audit can be fairly expensive to conduct, but the long term energy savings usually make the investment worth it.
