The radiant energy field in an office environment varies widely, in time and space, depending on numerous internal and external factors. The conventional thermal load calculation alone is inadequate for the basis of thermal comfort design of office environment. The present paper deals with a new approach for evaluating the thermal comfort in an office environment taking into account the radiation field as well as energy efficiency. The method utilizes a PMV model based on Fanger's comfort equation. combined with a simulation-aided software, SAPLO. The results of analyses indicate that the present approach is effective in assessing the relationship between the thermal comfort and the energy consumption.
