Study on the Built Environmental Systems utilizing the Moderate Fluctuation of Environmental Factors

本研究的目的是为了了解人体的运动特性和舒舒萨感觉的特点，揭示亮度感觉与生物钟的关系，从而对建筑的被动降温和采光设计有更好的认识。结果发现，在自然通风的房间里，大多数受试者在给定的热环境中对气流的波动非常敏感，同时也非常活跃地感到凉爽。根据傅立叶分析，从频谱中获得的归一化气流速度，受试者在有铃声感觉期间的归一化气流速度的幅度是没有感觉的时候的两倍。归一化风速波动的特点是先突然增加，然后指数减小。研究发现，使用窗外日光的受试者可以感觉到采光中的“亮”或“微亮”，感觉到的时间与实际相差很小。假设人体暴露在热中性环境中，人体内产生3W/m^2的热和湿(火用)，其中三分之一，即1W/m^2(火用)在人体内消耗。其余的，2W/m^2的热和湿(火用)，正在向环境流动。

The purpose of this study is to find out both the exergetic characteristics of human body and the characteristics of 'suzusisa' sensation, and to reveal the relationships between the brightness sensation and the biological clock, and thereby to have a better understanding for passive cooling and daylighting design of buildings. Followings are results.It was found that most of the subjects in a naturally-ventilated room were very sensitive to the fluctuation of the air current in the given thermal environment and at the same time very active in having coolness.According to the Fourier analysis, normalized air velocity obtained from spectra, the amplitude of the normalized air velocity during the period in which the subject had 'suzusisa' sensation is twice that in which she did not. The characteristics of the wave of the normalized air velocity is to increase suddenly and then decrease exponentially.It was found that the subjects who used daylight available from the windows can sense 'bright' or 'slightly bright' in the daylighting, and there are most little difference in the period of times between he or she sensed and actual.Provided that the human body at general office work is exposed to the thermally neutral environment, the thermal and wet exergy of 3 W/m^2 is produced within body, its one-third, namely 1 W/m^2 of the exergy is consumed within the human body. The rest, the thermal and wet exergy of 2 W/m^2, is flowing out toward the environment.
