冰上运动建筑曲面光伏参数化集成设计研究

Design of Photovoltaic Parametric Integration of Curved Surfaces of Ice Sports Venues

2022年冬奥会成功举办,国内掀起了冰上体育运动的热潮,冰上运动建筑需求量和能源消耗量随之增长。光伏建筑一体化(Building Integrated Photovoltaic,BIPV)作为建筑节能的主要手段之一,在体育建筑屋面具有较大的集成潜力。通过建立寒冷地区曲面冰上运动建筑典型模型进行集成设计研究,基于Grasshopper参数化平台实现新型柔性CIGS薄膜光伏组件沿屋面曲线形态的优化布置,从两个层级出发,提出参数化设计方法与构造措施。通过Honeybee进行能耗模拟,结果表明,该柔性光伏系统全年可以为冰上运动建筑降低15.82%的能量消耗,进而验证了该方案的节能性,为建筑师进行寒冷地区曲面冰上运动建筑设计的节能优化设计提供数据支撑及科学依据。

With the successful holding of the 2022 Winter Olympics,there has stirred up a spree of ice sports in China,and the demand for ice sports buildings and energy consumption have increased.As one of the main technologies of building energy conservation at present,photovoltaic building integration has great integration potential in the roof of sports buildings.Taking the curved ice sports building in the cold region of China as the research object,to carry out the integrated design research.Based on the grasshopper parametric platform,the optimal arrangement of the new flexible CIGS thin-film photovoltaic modules along the roof curve can be realized,and the parametric design method and construction measures are proposed from two levels.Through Honeybee energy consumption simulation calculation,the results show that the photovoltaic system of this scheme can reduce the energy consumption of ice sports buildings by 15.82% throughout the year,thereby verifying the energy saving of this scheme.Provide data support and scientific basis for architects to optimize energy-saving design of curved ice sports buildings in severe cold areas.
