Human comfort as a function of location in a room with one window wall at a temperature different from the other walls is studied. Computer models of the radiant field in a room and of the thermal response of the human body are used to obtain the experimental data. The factors affecting human comfort in a typical office room with one wall exposed to common northern United States winter temperatures are discussed in detail. The computer programs utilized in this research are described and their appropriateness as models is justified with current thermal environmental information. The parameters of the research are outlined, and a description of the goals and assumptions is given. The conclusions reached from the research are documented in graphs and text.
