Home Energy Audit/Professional Energy Assessment
During a Professional energy assessment we go into great detail to assess your home’s energy use. The energy auditor will do a room-by-room examination of the residence, as well as a thorough examination of the attic, crawl space and exterior of the home. Our standard professional energy assessments will include a blower door test and a thermographic scan. Our premium professional assessments also include a depressurization test on your duct work to determine the leakage amount along with the tests included in the standard professional assessment. Check out the Energy Saver 101 home energy audit infographic to get an idea of what our energy auditors look for and the special tools they use to determine where a home is wasting energy.
Preparing for an Energy Assessment/Audit
Before the energy auditor visits your house, make a list of any existing problems such as condensation and uncomfortable or drafty rooms. Have copies or a summary of the home’s yearly energy bills. (Your utility provider can get these for you.) Auditors use this information to establish what to look for during the audit. The auditor first examines the outside of the home to determine the size of the house and its features (i.e., wall area, number and size of windows). The auditor then will analyze the residents’ behavior:
- Is anyone home during working hours?
- What is the average thermostat setting for summer and winter?
- How many people live here?
- Is every room in use?
Your answers may help uncover some simple ways to reduce your household’s energy consumption. Walk through your home with the auditors as they work, and ask questions. They may use equipment to detect sources of energy loss, such as blower doors, infrared cameras, furnace efficiency meters, and surface thermometers.
You have successfully completed the first step towards improved energy efficiency – the energy audit. Now you’ve seen your efficiency report card and know all the steps you can take to make improvements. Your auditor will help you develop a home improvement plan that guarantees work is done in the correct order to maximize effectiveness and minimize dangerous or costly side-effects. Some things you may be able to do DIY, but it’s important you follow this plan. Otherwise, you will have to hire a different contractor for each job, which will be more expensive and will likely end up undoing work already done, as individual contractors don’t understand how a home works as a system. After all the work has been completed, your energy auditor will re-test your home to make sure that the solutions are saving energy as expected.
