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

本研究的目的在于了解人体的（火用）特性和“铃兰”感觉的特性，揭示亮度感觉与生物钟的关系，从而对建筑物的被动冷却和采光设计有更好的认识。结果表明，在自然通风的室内，大多数人对给定热环境下的气流波动非常敏感，同时又非常积极地追求凉爽，根据傅立叶分析，由谱得到的归一化风速，在受试者具有“SuzuSisa”感觉的时间段期间的标准化空气速度的幅度是她没有感觉的时间段期间的两倍。归一化风速的波动特征是突然增大然后指数下降。研究发现，使用窗户提供的日光的受试者可以在日光照明中感觉到“明亮”或“轻微明亮”，并且他或她感觉到的时间与实际时间之间的差异很小。如果人体在一般办公室工作时暴露于热中性环境中，环境中，人体内产生3 W/m^2的热、湿火用，其1/3，即1 W/m^2的火用在人体内消耗。其余的，即2 W/m^2的热和湿火用，则流向环境。

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.
