The 4th Conference of Green Building Alliance in Cold and Cold Regions was successfully held in Sino-Singapore Tianjin Eco-City

On November 24-25, the "4th Green Building Alliance Conference and Green Building Technology Forum in Cold and Cold Regions", sponsored by the Green Building and Energy Conservation Professional Committee of China Urban Research Society and jointly hosted by Northern Green Building Base and Tianjin Eco-City Green Building Research Institute, was successfully concluded in Sino-Singapore Tianjin Eco-City. The conference invited China Urban Science Research Association, Singapore Construction Authority, Germany Passive housing Research Institute and the northern provinces and cities construction authorities leadership, engaged in green building and building energy conservation experts and scholars to attend. In addition, more than 300 representatives from green building industry related scientific research institutions, colleges and universities, green building project design and construction units, real estate development, survey and design, construction supervision, property operation and other related enterprises, related building materials products and equipment manufacturers attended the conference. The conference was greatly assisted by the Green Building Professional Committee of Tianjin Urban Science Research Society and other local green building and building energy efficiency professional committee (association), China Academy of Building Science and other enterprises and the Global Environment Facility Tianjin Project Office.

At the opening ceremony, Wang Jun, Deputy Director of China Green Construction Commission, and Zhang Yanfa, Deputy Director of Sino-Singapore Eco-City Management Committee, delivered speeches successively.

Vice Director Wang Jun, on behalf of the China Green Construction Committee, first of all thanked the Sino-Singapore Tianjin Eco-City Management Committee and all the units that have given support for the smooth convening of the conference. In his speech, he pointed out that when the state formulated the "13th Five-Year Plan" key research and development plan, green buildings and building industrialization were included in the plan as urbanization and urban development fields. With the construction of ecological civilization, green development and new urbanization, green buildings will usher in major historical opportunities. He also briefly reviewed the achievements made in the field of green building in China and cold and cold regions in recent years. It is hoped that the participants will actively exchange the experience of promoting the development of green buildings around the world, in-depth discussion of green building related technologies and methods suitable for the region, and make contributions to promoting the faster and better development of green buildings in this region.

Deputy Director Zhang Yanfa said that the eco-city, as a flagship project of Sino-New Zealand cooperation under the Ministry of Housing and Urban-Rural Development, has the responsibility to undertake relevant work, especially the healthy development of green buildings in cold areas in the north, including the exploration and promotion of green building indicators, planning, design, construction, evaluation, use and maintenance. The eco-city is the first demonstration in the world to change the green building from post-evaluation to pre-warning, process supervision, post-evaluation and tracking management, forming a series of local standards. The eco-city ensures the gold content of green buildings by innovating the green building management model evaluated by the third party.

This session of the conference focused on green building integrated technology, passive house and building industrialization, green building development experience exchange and other topics.

At the comprehensive Technology Forum, Wang Qingqin, vice president of China Academy of Building Science, comprehensively introduced the overall development of green building and building industrialization from four aspects: policies, standards, current situation and trend, provided a large number of detailed relevant data information, and summarized the development trend of green building in "two lines", "two sides" and "several points". This paper expounds the development focus of building industrialization in the "thirteenth Five-Year Plan". Berthold, Executive director of the German Passive House Institute. With the title of "Opportunities and Challenges of passive House in China", Mr. Kaufmann mainly explained the five basic elements and key technical characteristics of passive house, briefly introduced the main features and applications of the 9th version of PHPP passive house design package, the certification of passive house in Germany, and the promotion and application of passive house in China.
