From October 18th to 21st, 2025, the "CAE-RAEng Academic Exchange on Low-carbon Building ", co-hosted by the Chinese Academy of Engineering (CAE) and the UK Royal Academy of Engineering (RAEng) and organized by China National Building Material Group Co., Ltd., was held in Bengbu, Anhui Province and Shenzhen, Guangdong Province. More than 70 participants from both academies, universities and industries from the two countries attended the event.

The event was held under the mechanism of the China-UK Steering Committee for Engineering and Technology Cooperation. CAE Member Peng Shou and RAEng Fellow S. Ravi P. Silva, also an International Member of the CAE, served as the conveners. During the event, the "Seminar on Building-Integrated Photovoltaics (BIPV) and Sustainable Development" was held. At the seminar, academy members/fellows and experts from China and the UK delivered reports and conducted in-depth discussions on topics such as cutting-edge technologies of BIPV, full-process development of key materials, and technical and economic feasibility. CAE Member Meng Jianmin and Cheng Huiming, a member of the Chinese Academy of Sciences, presided over the seminar, and CAE Member Ling Wen was invited to deliver a keynote presentation. Liu Chang, Deputy Director-General of the Department of International Cooperation of the CAE, delivered an opening speech on behalf of Prof. Chen Jianfeng, Secretary-General of the CAE.
