| Research Abstract |
The aime of this project is the quantification of the effect of each environmental factor on the synthesized or the common scale of evaluation and the comaprison of the environmental effect on between the subjective evaluation and performance of a simple task. Subjects are healthy male and female students. Environmental conditions are four categories of temperature (22, 26, 30 and 34 C in summer; 10, 15, 20 and 24 C in winter), noise (40, 50, 60 and 70 Leq(A)) and three categories of illuminance (170, 700 and 1480 1x), and the number of the total combination is 48. The exposure time is 90 minutes, which contains 40 minutes simple task. Subjects are demande to choose each of the three categories of synthesized uncomfortableness. The number of total samples obtained in the three-year experiment is 2145 in all. The data are analyzed by the crosstable and the second method of quantification. The results are shown in the below.
1. It is possible to evaluate by adding the each environmental effect on the synthesized scale. When each environmental factor is extreme, however, 'uncomfortable' state is determined regardless of other factors. Although the additive model is not valid strictly in such a case, the model is valid enough in a practical use. The dividing points are determined to apply to the estimation of the residents evaluation and the design of a combined environment.
2. Non-experimental factors --- such as sex, personality and the difference between the room air temperature and the outdoor one --- also affect the subjective evaluation significantly, however, the degree of those effects are not so extreme.
3. It has shown experimentally that the environmental effect on the subjective 'uncomfortableness' and the simple task performance differ significantly. This is one of the valuable finding of this project, because there are many general suggestion but a little experimental results.
