Home Energy Analysis
OPPD encourages customer-owners to improve the energy efficiency of their homes. Many times, simple improvements help save on energy bills year-round. When making your home more energy-efficient, it’s important to keep air quality and proper fresh-air ventilation in mind. For more information, visit DOE’s - Air Sealing and Fresh-air Ventilation for Existing Homes.
A Home Energy Analysis is a great tool to help find problem areas and assess the best measures to take so you can provide a safe and comfortable environment for your family.
There are several options available for measuring the energy efficiency of your home from online tools to hiring a professional to complete a comprehensive analysis. Here are some examples of just a few.
- The U.S. Department of Energy provides written directions on their Do-It-Yourself Home Energy Assessments web page.With a simple but diligent walk-through, you can spot many problems in any type of house.
- The Home Energy Saver Calculator computes home energy use on-line. The Home Energy Saver then generates a list of energy-saving upgrade recommendations for the user's consideration.
- If you would like a more comprehensive analysis, hire a professional Home Energy Rater.

Hire a Professional Home Energy Rater
If you are interested in receiving specific recommendations for improving the efficiency of your home, consider contacting a professional Home Energy Rater. A professional rater can use a variety of techniques and equipment to determine the energy efficiency of your home. Thorough analysis 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.
For the blower door test, all of the home's windows and exterior doors are closed. A fan is then installed in the front door with a special airtight seal. With the fan running, the energy rater monitors the flow of air through the fan as well as the air pressure in the home.
Once the home is sealed and depressurized, the rater can detect where air is leaking into or out of the home. An infrared imaging camera can then help the customer visually see the temperature difference where there is air leakage.
In addition to the air leakage test, the rater will perform a visual inspection of accessible areas in your attic, basement and crawl spaces and recommend how to seal and/or insulate these areas.
