- Abstract
- A comparative evaluation of various portable infrared sensing systems used for detecting heat loss anomalies within building envelopes was performed. This is the second of a two-stage applied research program sponsored by the Department of Energy to assess the application and reliability of using infrared technology. Twelve single-family residences in three cities from the Weatherization Program of the Community Services Administration were employed as field samples. The results of infrared surveys carried out by thermographic surveying firms and those by the National Bureau of Standards were analyzed and compared in the categories of: completeness of scanning, identification of defects, weather condition of inspection, and method of equipment operation. The thermograms of uninsulated areas, sketches of observed thermal deficiencies, and total areas of defects for each dwelling are presented.
