On March 15, 2024, the review meeting of the national standard "test method of solar thermal coefficient of building doors and windows simulated light source method (draft for review)" compiled by China Academy of Building Sciences Co., Ltd. and relevant units was successfully held in Beijing. The meeting was attended by experts from the competent department of standards, relevant units and members of the team. The meeting was presided over by Deputy Secretary-General Liu Huitao of the National Technical Committee for Standardization of curtain wall doors and windows. The Meeting formed a review expert group headed by Professor Yan Yuqin and vice-headed by Wang Shuangjun Professor senior engineer.
Dr. Zhang Xichen, director of the Research Center of Huanneng Science and Technology Building curtain wall doors and windows, and secretary general of the National Technical Committee for Standardization of building curtain wall doors and windows, made a speech and made a speech. He first expressed his gratitude to the leaders and experts attending the meeting for their support for the compilation of this standard. At the same time, he emphasized the significance of this standard to building energy conservation and introduced the future of our country, the development direction of window and curtain wall standardization work.
