Public buildings should set an example of green buildings and strictly implement green building standards. This shows that there is still a lot of room for public building energy conservation in the work of energy conservation and emission reduction and coping with climate change, and it has a position that cannot be ignored. Energy efficiency of public buildings is an important part of building energy efficiency, and related work has been paid attention to and achieved great results. In this year's national "two sessions", energy saving in public buildings has also become a topic. Hou Ximin, director of the Housing and Urban-Rural Development Department of Anhui Province, suggested that public buildings should set an example of green buildings and strictly implement green building standards. This shows that there is still a lot of room for public building energy conservation in the work of energy conservation and emission reduction and coping with climate change, and it has a position that cannot be ignored. The road to energy saving in public buildings is in China, where there are a large number of public buildings and considerable energy consumption. According to statistics, the annual electricity consumption of office buildings and large public buildings of state organs accounts for about 22% of the total electricity consumption of cities and towns in China, and the annual electricity consumption per square meter is 10 to 20 times that of ordinary houses. The energy-saving potential of large public buildings is above 30%. Therefore, for more than ten years, the attention to public buildings has been continuously strengthened and the work has been deepened. During the Eleventh Five-Year Plan period, the energy-saving work of public buildings was fully launched. In 2005, the former Ministry of Construction started the relevant work, and the Ministry of Science and Technology put the compilation, review and promulgation of the Design Standard for Energy Efficiency of Public Buildings on the work agenda. 2007 is an important year for energy conservation of public buildings. The Notice of the State Council on Printing and Distributing the Comprehensive Work Plan for Energy Conservation and Emission Reduction and Several Opinions on Strengthening the Construction and Management of Large Public Buildings were issued. The former Ministry of Construction issued a series of policies and methods, such as energy audit guidelines, implementation plan of energy-saving supervision system construction, and energy consumption statistics methods, specifically for office buildings and large public buildings of state organs. The Ministry of Finance and the Ministry of Housing and Urban-Rural Development have carried out energy consumption statistics, energy audit and energy efficiency publicity for office buildings and large public buildings of state organs nationwide, and carried out pilot projects for the construction of dynamic monitoring platforms for energy consumption of public buildings in some provinces and cities, and achieved good results. At the same time, the pilot work of building a conservation-oriented university has started. It is worth noting that public buildings have always been one of the contents in the evaluation and identification of green buildings during the Eleventh Five-Year Plan period, which has promoted the energy saving of public buildings. Through various efforts, from 2005 to 20 10, public institutions nationwide saved 339 1 10,000 tons of standard coal and reduced 84.775 million tons of carbon dioxide emissions. 20 1 1 year energy consumption per unit building area decreased 16.8% compared with 2005. During the "Twelfth Five-Year Plan" period, the energy conservation of public buildings was further deepened. 20 1 1 The Ministry of Finance and the Ministry of Housing and Urban-Rural Development issued the Notice on Further Promoting the Energy Efficiency of Public Buildings, demanding the establishment and improvement of the energy efficiency supervision system of public buildings, especially large public buildings, so as to realize the measurable and operable energy consumption of public buildings. The Notice on Further Promoting Energy Efficiency in Public Buildings also calls for vigorously promoting institutional innovation and combining subsidies for energy-saving renovation in key cities with contract energy management mechanisms. To this end, the Ministry of Finance and the Ministry of Housing and Urban-Rural Development organized the construction of energy-saving supervision platform for public buildings, the demonstration of key cities for energy-saving transformation of public buildings, the construction of energy-saving supervision platform for universities and the demonstration of energy-saving transformation of universities. In addition, for example, the revised national standard 2065438+2005 "Design Standard for Building Energy Efficiency" has been released one after another. During the "Twelfth Five-Year Plan" period, the energy-saving renovation of public buildings began to be implemented on a large scale. By the end of 20 12, more than 40,000 public buildings have been completed, 9,675 buildings have been audited for energy, 8,342 buildings have been publicized for energy consumption, and more than 3,860 buildings have been dynamically monitored. Shanxi, Liaoning, Jilin, Anhui, Henan and Hubei provinces were identified as the fifth batch of pilot projects for the construction of dynamic monitoring platforms for energy consumption, and Shanghai was identified as the second batch of key cities for energy-saving renovation of public buildings. 77 institutions of higher learning, including China Geo University (Beijing) and Huaqiao University, have been identified as pilot projects for the construction of conservation-oriented campuses, and 4 institutions of higher learning, including Central Party School and Tsinghua University, have been identified as demonstration projects for comprehensive energy-saving transformation. Obviously, the energy-saving work of public buildings goes hand in hand with energy consumption supervision, energy-saving transformation and green development. Green development of public buildings Green buildings are "four sections and one environmental protection" buildings in the whole life cycle, and have made great achievements since their introduction. Green building evaluation logo is the symbol of green building, and public buildings have always been the object of this evaluation. 20 13 significant progress has been made in the development of green buildings. The General Office of the State Council issued the Notice on Forwarding the Green Building Action Plan of the Development and Reform Commission and the Ministry of Housing and Urban-Rural Development, which made the development of green buildings a national strategy, and the energy conservation of public buildings became a part of the green building action. In the Green Building Action Plan, it is clearly stated that government-invested state organs, schools, hospitals, museums, science and technology museums, gymnasiums and other large public buildings with an area of more than 20,000 square meters, such as airports, stations, hotels, etc., will fully implement green building standards from 20 14, and strengthen the review of the implementation of standards. We should actively carry out energy-saving renovation of existing public buildings. During the Twelfth Five-Year Plan period, 60 million square meters of public buildings and 60 million square meters of office buildings of public institutions will be renovated. 20 14 The General Office of the Ministry of Housing and Urban-Rural Development, the General Office of the National Development and Reform Commission, and the General Office of the State Organs Administration Bureau issued the Notice on Promoting Green Building Action in an All-round Way in the Construction of Public Welfare Buildings and Large Public Buildings Invested by the Government, which strengthened the main responsibility of all parties involved in the construction and the management of the whole construction process. In this context, various localities have formulated relevant policies to promote the green development of public buildings. 20 13 Shaanxi Province has compiled five engineering construction standards, including "Green Design Standard for Public Buildings in Shaanxi Province (Draft for Comment)". 20 13 Jiangxi Province issued the Implementation Opinions on Developing Green Buildings in Jiangxi Province. Shanghai has formulated the engineering construction standard "Green Design Standard for Public Buildings", which has been officially implemented since September 20 14 1 day. Public buildings that need to be newly built, rebuilt or expanded shall be designed in accordance with the Green Design Standard for Public Buildings. During the "Twelfth Five-Year Plan" period, Shanghai was included in the second batch of national key cities for energy-saving renovation of public buildings. It is required to complete the target task of energy-saving renovation of 4 million square meters of public buildings before August 20 14, and each energy-saving renovation project of public buildings can enjoy the state financial subsidy of 20 yuan per square meter. Since 20 14, Fujian province has fully implemented green building standards for public welfare projects invested by the government, large public buildings with an area of over 20,000 square meters, residential quarters with an area of over 65,438+10,000 square meters, and affordable housing invested by Xiamen, Fuzhou and Quanzhou. During the Twelfth Five-Year Plan period, the combination of public building energy conservation and green building promoted the development of public building energy conservation. The new trend of public building energy conservation * * * Public building energy conservation has a new goal during the "Thirteenth Five-Year Plan" period, and related work has also made new progress at the beginning. 20 16 1 1 the State Council released the "13th Five-Year Plan" comprehensive work plan for energy conservation and emission reduction, and public buildings were listed in the key energy-saving fields, showing the importance attached to energy conservation of public buildings. The 13th Five-Year Comprehensive Work Plan for Energy Conservation and Emission Reduction requires public institutions to take the lead in implementing green building standards, and all new buildings will meet the green building standards. By 2020, the energy consumption per unit building area and per capita energy consumption of public institutions will be reduced by 10% and 1 1% respectively compared with 20 15 years. Promote public institutions to establish energy consumption benchmarks and disclose energy resource consumption information. Implementation of public institutions energy-saving demonstration pilot, to create 3000 energy-saving public institutions demonstration units. The "Thirteenth Five-Year" comprehensive work plan for energy conservation and emission reduction also requires strengthening building energy conservation. During the "Thirteenth Five-Year Plan" period, the energy-saving renovation area of public buildings will exceed 654.38 billion square meters. In addition, the 13th Five-Year Comprehensive Work Plan for Energy Conservation and Emission Reduction requires that public institutions should be promoted to implement energy-saving transformation by means of contract energy management, actively promote the government to purchase contract energy management services, and explore the energy trust model. The "Thirteenth Five-Year" comprehensive work plan for energy conservation and emission reduction clearly points out the goal of energy-saving development of public buildings, which makes the work in the next five years have rules to follow. Starting from 20 15, the Ministry of Housing and Urban-Rural Development revised the original Guidelines for Energy Auditing of Office Buildings and Large Public Buildings, and completed the Guidelines for Energy Auditing of Public Buildings, which were officially released on 20 16 and 12. The original Guide to Energy Audit of National Office Buildings and Large Public Buildings serves national office buildings, large public buildings and university campuses. The revised Guidelines for Energy Audit of Public Buildings are applicable to all types of single public buildings, which are different from public institutions and park buildings while expanding their scope. At the same time, the energy audit is refined and graded to make it more operational in practical work. In order to standardize the energy consumption supervision of provincial public buildings, strengthen the acceptance and evaluation of energy consumption monitoring platforms, ensure the safe and effective use of funds, and promote the operation and maintenance of platforms, the Ministry of Housing and Urban-Rural Development formulated the Interim Measures for the Acceptance and Operation Management of Energy Consumption Monitoring Platforms of Provincial Public Buildings in 20 15, which was released in April 20 16, and is a new content of energy conservation supervision of public buildings. From June, 2065438 to June, 2007, the Ministry of Housing and Urban-Rural Development also issued the Specification for Data Submission of Energy Consumption Monitoring System for Provincial Public Buildings, which is the revised version of the original Specification for Data Submission of Energy Consumption Monitoring System for Office Buildings and Large Public Buildings of State Organs. The industry believes that in addition to green development and energy-saving transformation, energy consumption supervision is particularly important for energy conservation of public buildings in the "Thirteenth Five-Year Plan". This is because since the "Twelfth Five-Year Plan", the assessment method of building energy efficiency in China has gradually changed from the control method aiming at technical measures to the total energy consumption control method, which is the need of deepening energy conservation work. The energy-saving momentum of public buildings is strong, and all localities have positive attitudes towards energy-saving of public buildings. They not only set goals, but also put them into action. The Beijing Municipal Commission of Housing and Urban-Rural Development and other four departments jointly issued the Action Plan for Energy Efficiency Improvement of Public Buildings in Beijing (20 16-20 18). Accordingly, the new public welfare buildings and large public buildings invested by the government in Beijing will fully implement the two-star and above standards for green buildings; By the end of 2065438+2008, the energy-saving green transformation of public buildings with an area of not less than 6 million square meters will be completed, saving about 60 thousand tons of standard coal. At the same time, it will also build and improve the policy and standard system of energy-saving operation and energy-saving green transformation of public buildings, innovate the energy-saving working mechanism of public buildings, and complete the construction of energy-saving management service platform of public buildings by the end of 20 18. The Department of Housing and Urban-Rural Development of Shandong Province has compiled the Key Points of Planning Review of Green Public Buildings in Shandong Province (for Trial Implementation), which requires the competent urban and rural planning departments at all levels to make clear the star standard of green buildings when issuing the planning conditions for residential land, public * * * management and public * * service facilities and commercial service facilities, and the projects must at least meet the one-star green building standard. 2065438+May 2006, the second phase of the energy consumption monitoring project for office buildings and large public buildings in Qinghai Province was completed after two years of construction, and the energy consumption data of 243 buildings and 3028 nodes were monitored, an increase of 43 buildings and 528 nodes compared with the original implementation plan. During the "Thirteenth Five-Year Plan" period, the energy-saving renovation of existing buildings in Guangxi will focus on the renovation of existing public buildings and office buildings of public institutions. The renovation area of public buildings in public institutions is more than 5 million square meters, and the energy-saving renovation of public buildings strives to save about 200,000 tons of standard coal in five years. During the "Thirteenth Five-Year Plan" period, new buildings in Hunan Province will fully implement the design standard of energy saving rate above 65%, and by 2020, the goal of transforming existing public buildings100000 square meters will be achieved. During the "Thirteenth Five-Year Plan" period, Hebei Province issued the target task of energy-saving renovation of existing buildings of public institutions, 1.4 1.56 million square meters. 20 16 12 Chongqing science and technology benefiting people project-demonstration project of green key technologies integration and application of large public buildings passed the pre-acceptance. At present, more than 290,000 square meters of public buildings in Chongqing are undergoing green building application demonstrations such as intelligent rainwater recycling, temperature and humidity independent control air conditioning, and the energy saving rate is 20%. In fact, as the focus of energy conservation, energy conservation of public buildings is highly valued by all localities. Although there are many problems in the construction of some government-invested construction projects and the development of energy conservation faces many difficulties, the vigorous development of energy conservation in public buildings in various places indicates that the energy conservation of public buildings will achieve more fruitful results in the 13 th Five-Year Plan.
