One of the key components of an effective home energy audit is infrared thermography. Infrared thermography (or infrared imaging, infrared diagnostics, a rose by any other name...) consists of a thorough visual inspection of a home, including the basement, attic, and all the nooks and crannies, with an infrared camera or another infrared assessment device. It essentially takes the guess-work out of pinpointing the drafts and the leaky spots within a home — registering, as it will, the exact temperature of various spots within the home, and, depending on the device used, providing you, the homeowner, with a precise visual representation of the imperfections in your home's thermal envelope.
