AbstractThe calculation of energy interchange by radiation between the surfaces that enclose a room is an important step in the design of both air-conditioning and lighting systems for buildings. These calculations require the evaluation of special factors that depend on the shape and the radiation properties of the room surfaces. The short-wavelength radiation from lights and the sun, and the long-wavelength radiation that is emitted by the surfaces have to be considered separately because the radiation properties of the surfaces can be very different for the different wavelengths. The programs presented in this report allow both the short-wave and long-wave factors to be evaluated by a digital computer. There can be up to fifty surfaces forming the enclosure, and it is assumed that over each of these surfaces the surface reflectivity, emissivity, temperature and illumination are uniform.
