Abstract
This paper presents a simple design procedure for dealing with the requirements for a comfortable thermal environment. From the expected activity level and clothing insulation of the people concerned, a subjective temperature is calculated which will provide thermal comfort. This subjective temperature is a combination of physical parameters of the environment, i.e., air and mean radiant temperatures, and air speed.
Consequently a heating system must be designed so that the parameters would combine to give the optimum subjective temperature. This proposed procedure also considers other possible sources of discomfort, and gives an acceptable limits for them.
