Detecting Heat Loss in Structures

False-colored infrared images of a house (top or left) and a reactor vessel (bottom or right) at a power plant. Both of these images reveal areas of heat loss, indicating poor insulation for the house and structural weaknesses in the reactor.

Thermal infrared imaging is used to detect heat loss in buildings providing information on where further insulation is needed to reduce energy costs. The detection of heat loss in other structures can be used to identify problems early so that repairs can be made before serious and more costly damage occurs. Infrared imaging is used to detect roof leaks, moisture in walls and ceilings and for the inspection of leaks in windows, pipes, and in air conditioning and heating systems. In factories, infrared detectors are used to inspect ovens, kilns, boilers and refractories for cracks and weak spots. Infrared scanning is used to detect weak spots in river dikes, dams, and bridges allowing for repairs to be made before the situation becomes hazardous. Energy efficiency in cold rooms and large freezers is also studied using infrared detectors.
