Predicting Thermal Comfort of People in Naturally Ventilated Buildings 自然通风建筑中人体热舒适性的预测
本文介绍了一种预测自然通风建筑内人员热舒适性的新方法。该程序首先为每个重要风向获取拟建建筑物内感兴趣点与外部测风高度之间的速度比。这最好通过对建筑物的比例模型进行风洞试验来实现,但也有公布的此类比率来源。这些比率,加上建筑物引起的温度变化,被应用到代表现场的气象带上,以产生一个小时的温度- 按小时记录室内气候。该记录用于模拟人体热舒适性的程序。该计划按季节和一天中的时段列出了拟建建筑预计的热舒适时间百分比。这些信息使建筑师和工程师能够在设计自然通风建筑时做出更合理的决定。引文:研讨会论文,佐治亚州亚特兰大,1984年
A new procedure for predicting the thermal comfort of people in naturally ventilated buildings is described. The procedure starts by obtaining, for each important wind direction, velocity ratios between points of interest inside the proposed building and the wind-measuring height outside. This is best done with a wind-tunnel test of a scale model of the building, but there are also published sources of such ratios. The ratios, plus building-induced temperature changes, are applied to a weather tape representing the site, in order to produce an hour-by-hour record of indoor climate. This record is used in a program simulating human thermal comfort. The program puts out the percentage of time, by season and by periods of day, that thermal comfort is expected in the proposed building. This information enables architects and engineers to make more rational decisions in designing naturally ventilated buildings.
