Abstract: In the practice of the Beijing Olympic Winter Games in 2022 for the renovation and reuse of the 2008 Olympic legacy venues, PVC film-based clips integrated with the black coated fabric were employed as a shielding material, to reduce the influence of sunlight under the ethylene tetrafluoroethylene (ETFE) air pillow ceiling system and maintain a good and stable indoor environment. Based on winter outdoor meteorological parameters, we measured the temperature; solar irradiance; and illuminance of the playing field, as well as the upper and lower surfaces of the ceiling enclosure and its internal cavity. Meanwhile, a simulation of the indoor environment before and after the shielding was carried out. The distribution and transmission mechanism of light, humidity, and heat in the venue were studied. It was found that the shielding material can block more than 98% of the sunlight and solar radiation; and after the addition of shielding material, the temperature of the playing field changes throughout the day about 1 °C. The difference between the surface temperature under the ceiling and the indoor temperature is about 3 °C, which is not easy to condense. The physical characteristics of the shielding of the roof enclosure structure are revealed, and the shading and heat insulation performance of it is verified, so that the venue meets the requirements of the Olympic Winter Games in the indoor environment.
