Chengdu promotes energy-saving renovation of existing public buildings

According to the relevant person in charge of the Chengdu Bureau of Housing and Urban-Rural Development, the design standards for building energy efficiency in Chengdu have been increased from 50% to 65% since 2018. At the same time, the energy-saving design standards for provincial and civil buildings are strictly enforced, and the construction of civil building projects is carried out. Graphic design and review quality routine inspections and special inspections of building technology, supervise and urge relevant responsible entities to implement building energy-saving design standards.

"From the 6 aspects of public building project envelope thermal design, heating, ventilation and air conditioning design, water supply and drainage design, electrical design, renewable energy applications and annual energy consumption calculations for buildings, we have done a good job in large public buildings. Energy-saving design demonstration. At the same time, the 2018-2020 public building energy-saving renovation plan will be formulated, and the public building energy-saving renovation target will be included in the city's energy "dual control" target assessment system." According to the introduction, the Chengdu City In the past three years, the total area of energy-saving renovation of public buildings was approximately 2.43 million square meters. In 2021, we will continue to promote the energy-saving renovation of public buildings, and have issued a plan to complete the energy-saving renovation of 1.5 million square meters in 2021-2023, of which 460,000 square meters will be completed in 2021.

At the same time, in order to implement the national, provincial, and municipal “dual control” series of decisions on total energy consumption and intensity, effectively reduce building operation energy consumption, and effectively control total building carbon emissions, the construction of the “Chengdu City” was completed in 2019. Public building energy consumption monitoring information system", so far, there are 86 typical existing public buildings that have real-time energy consumption monitoring. Through the collection, storage, statistics and analysis of water, electricity, and gas energy consumption data of 86 typical existing public buildings, it has promoted the refined management of the energy consumption of public buildings; relying on the long-term cooperation of the city and district at the two levels. Mechanism, carried out three-year energy consumption statistics for 2018-2020 on 1272 civil buildings, laying a solid foundation for scientifically formulating public building energy consumption quotas and promoting building energy conservation and emission reduction.
