An instrumented energy audit uses a scientific approach to look at all of the areas of your home that use energy to help you decide the best way to upgrade insulation levels, air sealing, HVAC equipment and appliances. It also reveals other ways to help reduce your utility bills and improve the comfort of your home.
During our inspection, we use various tools including infrared cameras, blower doors, combustion analyzers and pressure pans. These tools collectively give our auditors the best data for diagnosing a home.
To measure insulation effectiveness, we may use an infrared scanner that looks at surface temperatures to see what is going on inside the walls. To measure air leakage we will use a blower door – this a large fan set up in an exterior door that pulls air out of the home and forces air to come in through all of the leakage points. The leaked air then leaves the house through the fan, allowing us to measure it numerically. To pinpoint air leakage, we may use a small smoke generator or a pressure pan. We use a combustion analyzer to measure several things that are happening inside your natural gas, propane, or oil heater and water heater. We also carry various other instruments to measure air flow, temperature, relative humidity, and pressure that we will use as needed.
The audit is priceless when performed by an experienced auditor! The energy auditor’s thorough analysis will direct your improvements at critical items and advise against fixing items that are not important. Our audit is generally $400, but in many areas this is subsidized down to $100 by your local utility or state program. Beware of free audits that do not thoroughly diagnose your home. As in any field, always inquire about professional certifications.
We will spend three to four hours in your home inspecting all rooms as well as the unfinished areas, such as the attic, basement, and crawlspace.
We recommend an adult who lives in the home join us so they can describe any household concerns with comfort and energy performance. This discussion will mostly take place at the beginning, but will continue throughout the audit as we uncover information about your home. We plan to share our findings before we leave.
You will receive a written report that goes into detail about your home’s energy usage and describes any problems we found that may contribute to comfort problems and energy concerns. We will also discuss any combustion safety issues and other possible health and safety concerns we diagnosed during our inspection.
Our staff is fully certified by BPI and RESNET, the two industry-accepted organizations that offer residential energy efficiency certifications.
Many states and utilities offer rebates for completed efficiency work – we can apply for these rebates on your behalf at the time of job completion.
