Abstract

Most of the studies on the evaluation on human environment are limited to those on a single environmental factor and few studies treat several factors synthetically, while there are many environmental factors in a room. Although there are several studies on the evaluation of the combined environmental factors, the main interest of those studies is the evaluation specific to a single environmental factor and not the synthesized evaluation common to every factor. However, detailed study of a single factor is not always useful when the improvement of the whole environment is aimed. The purpose of this study is to improve the environment in a room on the whole by introducing the concept of the synthesized evaluation and the nonspecific scale. The numerical contribution of each environmental factor-temperature, noise and illuminance-to the synthesized evaluation of "uncomfortableness" is determined by applicating the Second Method of Quantification of Hayashi to the experimental results on the linear combination simulation. It is demonstrated that "nonspecific uncomfortableness" is expressed by the addition of each weight score of the corresponding category of each factor. With this method, the values of our "uncomfortableness" to the daily combined environmental factors can be predicted in the moderate range, and the comparison of those effects of different kinds of environmental factors on the common scale become possible.
