This is a translation of the Chinese-language report Securities research report Please read the disclaimer at the end of the report Policy-driven growth potential of building energy efficiency and BIPV Carbon Neutrality Series Report No. 3｜ Mar 17, 2022 CITICS Research Core views SUN Mingxin Chief Basic Materials the Code refines requirements for energy-saving buildings. The 14th FYP for building energy conservation and green building development comes in the context of the carbon peaking and carbon neutrality goals and people’s increasing demand for a better living environment. We can summarize the key tasks proposed by the Plan into four aspects the direction of building development building high-quality green buildings, improving building energy efficiency, promoting ultra-low-energy buildings or ULEB, nearly-zero-energy buildings or NZEB, etc., building energy application promoting the application of solar-powered buildings, etc., building construction methods developing prefabricated buildings and prefabricated decoration, etc., the use of building materials promoting the penetration and application of green building materials, etc.. In general, measures such as improving the level of building energy conservation and adopting BIPV systems have become an important starting point for promoting the high-quality development of green buildings. The mandatory national standard defined by the Code can serve as the “constitution“ that must be followed in the engineering construction of building energy conservation-related projects. Basic Materials the new orders of listed companies miss expectations; the backlog orders of listed companies fall short of expectations; the recovery of real estate and infrastructure demand falls below expectations. ▍ Investment strategy Judging from the Plan and the Code, the two guideline documents have been issued one after another in the context of the carbon peaking and carbon neutrality goals and people’s increasing demand for a better living environment, which means that the policy system for building energy efficiency is gradually improving and the government s emphasis on building energy conservation has increased significantly, thus putting the high-quality and green development of building materials on the fast track.

Basic Materials improving building safety, health, livability, convenience and economy. A key item in the “Plan”, energy conservation performance requires improving the energy efficiency of incremental and existing buildings, as well as promoting ULEBs and NZEBs. 2 Building energy application Promoting the application of solar energy buildings; strengthening the utilization of renewable energy such as geothermal energy; implementing building electrification project building energy consumption system with electricity consumption as the core; and advancing regional building energy coordination. 3 Building construction methods Promoting new-type green construction methods, including vigorously developing steel structure buildings, actively promoting prefabricated concrete buildings, developing wood structure buildings according to local conditions, and actively developing prefabricated decoration. 4 Use of building materials Promoting the penetration and application of green building materials; increasing R promoting high-strength rebars, high-performance concrete, high-performance masonry materials, structural insulation integrated wallboard, etc.; as well as encouraging the development of high-performance prefabricated components and parts. The “column” tasks include the projects for promoting ULEBs, the energy-saving renovation of existing residential buildings, the construction of key cities to improve the energy efficiency of public buildings, the BIPV campaign, and the development of “13” standardized design and production system of prefabricated construction methods. Building energy efficiency, BIPV, prefabricated buildings, green building materials and other fields have become important starting points to promote the improvement of building energy efficiency level and the high-quality development of green buildings.

Overall target during the 14th FYP period By 2025, all incremental buildings in cities and towns will be built into green buildings in 2020, the proportion of incremental green buildings in cities and towns across China was be 77 of the incremental floor space in that year, the building energy utilization efficiency will be steadily improved, the building energy structure will be gradually optimized, and the growth trend of building energy consumption and carbon emissions will be effectively controlled, so as to basically form a green, low-carbon and circular construction and development mode, which will lay a solid foundation for peak carbon dioxide emissions before 2030 in the field of urban and rural construction. Basic Materials 2 In the part of guarantee measures, it mentions “doing a good job in the implementation of the ‘General Code for Building Energy Conservation and Renewable Energy Utilization’ and other standards”. It can be seen that the detailed requirements and enforceability of the “Code” provide the basis and guarantee for the implementation of the “Plan”. The “Code” first puts forward the energy consumption requirements that incremental buildings should meet. The average energy consumption level of incremental residential buildings and public buildings decreased by 30 and 20 respectively on the basis of various energy conservation design standards implemented in 2016, which are consistent with the targets set in the “Plan”; carbon emission intensity decreased by 40 on the basis of various energy conservation design standards implemented in 2016. In terms of energy conservation rate requirements, the average energy conservation rate of residential buildings in severe cold and cold regions should Basic Materials heat transfer, air tightness, window-wall area ratio of oute
