Energy Assessment Process (5 Steps)

A home energy assessment is a complete, in-depth analysis of a home's energy efficiency . During this procedure, your Building Energy Pros auditor will use state-of-the-art equipment to analyze how energy is being used and where energy loss is occurring. By conducting an energy evaluation, the auditor is able to identify ways to either stop or reduce energy loss, which could result in dramatic savings to your energy bills .

Once the audit is completed, you will receive a detailed report of the results. The report will highlight any problems and include the auditor's recommendations on what action needs to be taken to improve energy efficiency. An average home energy assessment takes about three hours to complete.

There are 5 steps to a home energy assessment:

  • Step 1 - Initial Interview

    During this interview, the assessor collects as much background information as possible about the house. Any existing energy or ventilation problems should be discussed at this stage, as well as your concerns, goals or any plans that you may have for your home (e.g. building an extension).

  • Step 2- Outdoor Inspection

    The outdoor inspection examines all the exterior aspects of the house. A thorough assessment is made of the doors, windows, overhangs and skylights - if any. The outside perimeter of the home will also be taken into account. This includes looking at the building orientation and any vegetation that affects shade and windbreak.

  • Step 3- Indoor Inspection

    The indoor inspection is divided into the following sections:

    Main Level & Basement

    The examination of this area includes: thermostat, furnace, water heater, basement wall and band joist insulation, ducts for sealing and insulation, window sealing and locking and glazing, weather stripping for doors and windows, flooring, washer hoses and overall character of all appliances.

    Upper Floors

    The examination of this area includes: attic hatch seals, canned lighting, attic insulation/ventilation and sealing of perforations in the ceiling below the attic.

  • Step 4- Blower Door and Infrared Tests

    This stage consists of two tests, each to ascertain different areas of concern:

    Blower Door Test

    The blower door test entails the use of specialized diagnostic equipment to measure the air tightness of the house. It will determine where any air leaks are occurring and what the total amount of that air leakage is. This test is also used to check if there are any moisture condensation problems, and to test the indoor air quality. The blower door test uses a powerful fan to depressurize the entire house and then check the rate at which air reenters the building through unsealed cracks and other openings in the building envelope.

    Infrared Thermal Image Scan

    In conducting this test, the auditor uses an infrared thermograph and a special infrared camera called a Forward Looking Infrared or FLIR camera. By using wavelengths which are invisible to the naked eye, the FLIR camera will measure temperature variations along the building's surfaces. In this way, "hot" and "cold" spots in the building envelope can be identified, allowing the auditor to form a picture of what's going on behind the walls. The scan enables the auditor to accurately pinpoint those areas where insulation and/or air sealing needs to be improved.

  • Step 5- Review Results

    The assessor will review the preliminary findings with you, giving you a general idea as to what improvements you can make to your home. Within one week, you'll receive a more detailed report by email. The second report will outline specific steps you can take to make your home more energy efficient. By making energy efficient improvements to your home, you can qualify for a number of tax incentives offered by the federal and state governments.

We were unaware of what was involved in an energy audit and your audior took the time to explain everything. We were impressed with the report which told us the areas in which we need to take action on. He never pressured us to use any particular contractors, he just suggested that we go to the Building Energy Pros web site to select contractors of our own choice. He did an excellent job and we HIGHLY recommend the Building Energy Pros. We already have recommended them to several of our neighbors. Again, EXCELLENT JOB!

The energy auditor was very good and helpful. He keeps in touch with me to answer any of my questions.

I was very satisfied with my energy audit. The auditor gave me some tips on attic insulation that were very helpful.

I was very satisfied with my energy audit. Thank you!

Very good service! I am going to replace the windows as the auditor had suggested.

I was very happy with the energy audit. THANKS!
A. M.

My energy audit was very helpful. Joe Dempsey, your auditor, identified some structural problems that I was not aware of and explained to me why I need more insulation.
J. F.

The auditor was EXCELLENT! He spent ALOT of time with me. I am going to take 3 to 4 of his suggestions and correct these small items to save on my energy bills.
M. B.

The auditor did a GREAT JOB! He knew a lot about older homes, which we have. The report was very comprehensive. Thank you!

Katherine McCaffrey

The auditor did a TERRIFIC JOB! The report was FANTASTIC! I will make all the repairs he suggested. I will definitely recommend him to everyone I know that could benefit from a home energy audit.
Steve Sleigh, Chevy Chase

The energy auditor was very professional and I am very satisfied with both the energy audit and the report I received. I will be referring the Building Energy Pros.
Tim Clary

I was very satisfied with the auditor. He was great and gave me some very valuable information. I will refer him to people I know who may need a home energy audit.

Your home energy audit proved to be very informative and helpful. I was not aware of the updraft created inside our walls because of the balloon framing construction. You said that that can cause heat to be pulled out of the house with the draft going up inside the walls and should be re-mediated. You also said that the attic insulation was insufficient and that fiberglass batts can leave spaces for around the edges causing heat loss and that it should have blown in insulation on top of what was there to seal the whole attic and increase the r factor. After going over your findings and telling me how you would fix the problems you told me how I could do it myself with stuff from the Home Center and for a quarter of the cost. Well, I did. I went into the basement and filled the bottom of the wall joist with unfaced insulation where they set on the sill plate. I then cut one inch foam board the size for each space and set it in and the sealed the edges of that with expanding foam as well as the sill plate to the foundation. I also sealed the sill plate to the foundation where the joist ran along it, as well as the top of those joist where it made contact with the subflooring. Next I went to the home center and rented their blown insulation machine and got ten bales of the insulation. I filled the attic on top of the batt insulation with about six inches giving another r-19 factor on top of the r-19 that was there. You said that the blown in would also help seal the heat loss around the edges of the batt. The work in the basement cost $144.00 and the work in the attic cost $328.00. After the 30% federal energy tax credit it will end up costing me about $330.00, which you said I should recover in savings in the first year. Thank You for all your advice and expertise. You made me aware of things I should consider and did.
