Save Money and Energy with a Home Energy Assessment (Text Version)
Below is a text version of the Home Energy Assessment video, which shows some of the ways that a contractor may test your home during an assessment, and helps you understand how an assessment can help you move toward energy savings. Note that the speaking and on-screen captions occur simultaneously during the video, but they are separated here for clarity.
The text below is spoken during the video.
Speaker: Core to any energy audit, you've got a Blower Door Test; an Infrared Camera Scan for homes with gas appliances, a gas water heater, a gas furnace; a building walk-through from the basement to the four corners of the attic; and a survey of all the appliances and the lighting; and you talk to the homeowner about how they are using the house.
Jason Dispenza: You assimilate all this data together into a report that a homeowner can use to prioritize different projects within the home. Identifying the source of the problem is what the audit will do. Once you have fixed the home and you want to retest the house you can benchmark those items that were identified in the energy audit.
Jason Dispenza: How this is applied within each individual house is important and the standards to which your auditor applied on the home is what gives the industry some sort of normalization. So if one energy auditor does an audit on your home and uses a BPI or HERS standard then another company that is a home performance contractor can come in, use that auditor's data to fix those items that were identified in the source of the energy audit.
