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.
