Abstract

Infra-red imaging techniques offer the possibility of mass monitoring the external temperatures of buildings such as factories and dwellings on a non-intrusive basis with the object of determining those losing an excessive amount of heat. It is shown that typically external surface temperatures are only a few degrees above ambient, and in order to relate thermal images to the surface temperature the emissivity of the material must be accurately known. Emissivities of common building materials in the range 2 - 5.6 μ have been determined and are tabulated.
