上海建筑楼顶风能资源的初步调查研究

Preliminary Studies on Wind Energy Resources of Shanghai Building Roof

研究了上海建筑楼顶风速与气象站数据的相关性。通过测试上海市同济大学嘉定校区和杨浦校区的某些高楼屋顶的24 h风速数据,将之与嘉定校区中德学院小型气象站的气象数据,以及上海徐家汇地区10 m高度测风塔上的气象数据进行对比,分析了上海市楼顶风速特点。经过比较,发现位于郊区的嘉定校区低层建筑楼顶的风速情况均可使用中德学院气象站的风速代替,但是高层建筑的风速情况还需进一步研究。而杨浦校区处于市区,地形复杂,各楼顶的风速不能以气象站的风速来估算,因此市区气象站的和各楼的风速相关性还有待进一步研究。

The correlation between building roof wind speed and weather station data in Shanghai are studied.It tests 24-hour roof wind speed of buildings on Jiading Campus and Yangpu Campus of Tongji University,which is compared with the meteorological data from the small weather station in Sino-German Institute on Jiading Campus and with the data from wind tower of 10-meter height in Xujiahui area in order to analyze roof wind speed characteristics in Shanghai.By comparison,it found that the roof wind speed of the low-rise buildings in suburban Jiading campus could be substituted with the data of Sino-German Institute,but the speed of the high-rise buildings needs further study.The Yangpu District is in urban with complex terrain,the roof wind speed could not be estimated with the data of weather station.So,the correlation of velocity from weather stations in the urban areas and the buildings remains to be further studied.
