Abstract
This paper describes a newly developed technique for estimating heat-loss rate using an infrared television system. A device called a heat-flow reference pad was developed that makes it possible to estimate quantitatively the heat-loss rate at the surface of a building without the need for a conventional heat-flow meter to be mounted on the surface. Technical considerations for the design of a heat-flow reference pad are presented. The infrared measurement technique predicted heat-loss rates in the laboratory and field within approximately 12%.
