Do-It-Yourself Home Energy Audits

There are several online, do-it-yourself home energy audit tools that you can use to gain an understanding of your energy use patterns and costs.  Based on these audits, you can change your inputs to see potential savings.  For example, you can increase the attic insulation, install curtains or drapes for windows and patio doors, reduce hot water usage, and switch from incandescent bulbs to energy efficient lighting.

For any of the DIY energy audits, you will be asked to provide information, including but not limited to:

  • electricity rate or cost per kilowatt-hour
  • energy use, such as:
    • actual or estimated energy requirements or wattages of electrical devices
    • hours per day of use for each device
  • home construction
    • type of construction
    • dimensions
    • windows and doors
    • insulation in the attic, floors and walls
  • heating, cooling and water heating systems

After the Audit - Using the Findings

Downloadable spreadsheet from UT Extension:

You can download an Excel spreadsheet from UT Extension to create a room-by-room home energy audit using actual wattages of devices and the hours of use per day.  Since you can save the spreadsheet on your computer, you can easily go back later and change wattages and hours of use to start identifying ways to lower energy use and costs.

Note: Excel may display standard security warnings when you open the spreadsheet:
  • you must 'Enable Editing' in order to use the spreadsheet
  • you must 'Enable Content' for the navigation buttons to function, but you can still use the mouse Ctrl + PageUp/Down to jump to the next/previous pages
  • you do not have to 'Make This a Trusted File'  LINE 
  • you can save the file locally and edit your entries later  END

Home Energy Saver™ - Lawrence Berkeley National Laboratory:

The Home Energy Saver™ (HES) empowers homeowners and renters to save money, live better, and help the earth by reducing energy use in their homes. HES recommends energy-saving upgrades that are appropriate to the home and make sense for the home's climate and local energy prices. The money invested in these upgrades commonly earns "interest" in the form of energy bill savings, at an annual rate of 20% or more (see examples). HES also estimates the home's carbon footprint and shows how much it can be reduced.  Click the logo this link:
