Recently, the Ministry of Housing and Urban-Rural Development issued the "14th Five-Year Plan for Building Energy Conservation and Green Building Development", which clearly states that by 2025, all new urban buildings will be fully constructed as green buildings, the building energy utilization efficiency will be steadily improved, and the building energy consumption structure will be gradually optimized. As a leader in energy-saving glass, the era of vacuum glass has come. The growth trend of building energy consumption and carbon emissions has been effectively controlled, and a green, low-carbon, and circular construction and development mode has been basically formed, laying a solid foundation for the urban and rural construction field to reach the peak of carbon before 2030. The wide applications of vacuum glass are totally helpful for low carbon future.
The plan proposes that, by 2025, the area of energy-saving renovation of existing buildings will be more than 350 million square meters, and the construction of ultra-low energy and near-zero energy consumption buildings will exceed 50 million square meters. The proportion of prefabricated buildings in urban new buildings will reach 30%. The installed capacity of solar photovoltaics in new buildings nationwide is more than 50 million kilowatts, the application area of geothermal energy buildings is more than 100 million square meters, the replacement rate of renewable energy in urban buildings reaches 8%, and the proportion of electricity consumption in building energy consumption exceeds 55%.
The plan also clarifies 9 key tasks of building energy conservation and green building development during the "14th Five-Year Plan" period - improving the quality of green building development, improving the energy conservation level of new buildings, strengthening energy conservation and green renovation of existing buildings, promoting the application of renewable energy, and implementing buildings. Electrification engineering, promotion of new green construction methods, promotion and application of green building materials, promotion of regional building energy coordination, and promotion of green city construction.
Key Tasks in Building Energy Efficiency and Green Building Development
◈ In terms of improving the quality of green building development, it is necessary to strengthen the construction of high-quality green buildings and improve the operation and management system of green buildings. Carry out green building creation actions. By 2025, new urban buildings will fully implement green building standards, and a number of high-quality green building projects will be built, and the people's sense of experience and gain will be significantly enhanced. At the same time, a star-rated green building promotion plan was launched. Adopt the "mandatory + voluntary" promotion model, and appropriately increase the proportion of star-rated green buildings in government-invested public buildings, large public buildings and new buildings in key functional areas. Guide local governments to formulate policies such as green finance, plot ratio awards, and priority awards, and support the development of star-rated green buildings.
◈ In improving the energy-saving level of new buildings, focus on promoting the promotion of ultra-low energy consumption buildings. By 2025, the construction of demonstration projects of ultra-low energy consumption and near zero energy consumption buildings will exceed 50 million square meters. At the same time, carry out the promotion project of high-performance doors and windows. According to the current situation of door and window technology in my country and the development direction of technology, the goal of improving energy-saving performance of doors and windows in different climate regions is proposed to promote the application of high-performance doors and windows. Shading facilities should be added according to local conditions to improve the safety, applicability and durability of shading facilities.
◈ In strengthening the energy-saving and green transformation of existing buildings, it is necessary to carry out energy-saving transformation of existing residential buildings. Strive to complete the energy-saving renovation of existing residential buildings nationwide by 2025, with an area of more than 100 million square meters. At the same time, promote the construction of key cities to improve the energy efficiency of public buildings. During the "14th Five-Year Plan" period, more than 250 million square meters of energy-saving renovation of existing public buildings have been completed.
◈ In promoting the application of renewable energy, building photovoltaic actions should be carried out. During the "14th Five-Year Plan" period, the cumulative installed capacity of solar photovoltaic in buildings will be 50 million kilowatts, and the policy system, standard system and technical system of solar photovoltaic building application will be gradually improved.
◈ In the implementation of building electrification projects, it is necessary to carry out alternative actions for building energy and electricity. By 2025, the proportion of electricity consumption in building energy consumption will exceed 55%. At the same time, promote the construction of new building power system. During the "14th Five-Year Plan" period, we will actively carry out pilot projects for the construction of new building power systems, and gradually improve relevant policies, technologies, standards and industrial ecology.
◈ In terms of promoting new green construction methods, it is necessary to establish a "1+3" standardized design and production system, focusing on how to use standardized components for integrated design, guide production units to carry out standardized mass production, gradually reduce production costs, and promote the industrialization of new buildings. continuous development.
◈ In terms of promoting the promotion and application of green building materials, it is necessary to increase investment in research and development of green building materials products and key technologies, encourage the development of prefabricated components and components with excellent performance, significantly increase the application ratio of green building materials in new urban buildings, and promote new functional environmental protection building materials products and supporting materials Application Technology.
◈ In terms of promoting regional building energy coordination, it is necessary to target various parks and public buildings such as new urban areas, functional parks, campus parks, etc., to promote the pilot construction of regional building virtual power plants, improve building electricity efficiency, and reduce electricity costs.
◈ In promoting the construction of green cities, it is necessary to carry out the construction of green and low-carbon cities and establish a benchmark for green and low-carbon development of buildings. Combined with building energy conservation and green building work, formulate a green and low-carbon city construction implementation plan and a green building special plan, clarify the green and low-carbon city development goals and main tasks, and determine the green building grade and layout requirements for new civil buildings. Promote the construction of green and low-carbon urban areas, realize the large-scale development of high-star green buildings, and promote ultra-low energy consumption buildings, zero-carbon buildings, energy conservation and green transformation of existing buildings, renewable energy building applications, prefabricated buildings, and regional building energy efficiency Improvement and other projects will be implemented to comprehensively improve the level of building energy conservation and green building development.
