摘要
国家雪车雪橇中心是2022年北京冬奥会延庆赛区核心区的竞赛场馆。不同于世界上的其他场馆,国家雪车雪橇中心的场地选址定在了山体南坡。为了规避南坡太阳辐射量高导致场馆用能大的缺陷,该场馆的设计采用了地形气候保护系统,为赛道提供遮阳的同时保护其免受风、雪等气候因素的影响,最大限度地降低能耗,实现“南坡变北坡”的设计目标。通过对国家雪车雪橇中心赛道太阳辐射进行实测,实地考察了赛道遮阳系统的遮阳效果。通过软件模拟分析结果与现场实测结果的对比,检验了太阳辐射模拟结果的有效性。分析了导致模拟数据与实测数据产生差异性的原因。研究表明,采用基于Grasshopper平台和Ladybug插件的太阳辐射模拟,能够有效反应雪车雪橇赛道的实际日照情况。
National Sliding Center is the competition venue in the core area of Yanqing District for Beijing 2022 Winter Olympics.Unlike other venues in the world,National Sliding Center is located on the southern slope of the mountain.In order to avoid the high solar radiation brought by the southern slope which leads to the defect of high energy consumption of the venue,a terrain-based weather protect system has been designed to provide shade for the track and protect it from wind,snow and other climatic conditions,to minimizing energy consumption and to achieve the goal of“south slope to north slope”.The solar radiation on the track of the National Sliding Center was measured,and the shading effect of the shading system was inspected by field measurement.The validity of the solar radiation simulation results is verified by comparing the results of numerical simulation with the field measured results.The reasons for the discrepancy between the simulated data and the measured data are analyzed.The research shows that the simulation of solar radiation based on Grasshopper platform and Ladybug plug-in can effectively reflect the actual solar conditions of the bobsleigh track.
