Decrease consumption by 15% during the 12th Five-Year Plan period for large-scale public buildings

During the “Twelfth Five-Year Plan” period, China will strive to achieve a 10% reduction in energy consumption per unit area of ​​public buildings and a 15% reduction in the energy consumption of large-scale public buildings. The Ministry of Finance and the Ministry of Housing and Urban-Rural Development jointly issued the "Notice on Further Promoting Energy Efficiency of Public Buildings" (hereinafter referred to as the "Notice"), which clearly defined the energy conservation goals of public buildings during the "12th Five-Year Plan" period.

During the “Twelfth Five-Year Plan” period, the two departments took a series of measures to strengthen energy conservation management of newly-built public buildings, promote energy-saving renovation of public buildings, promote energy efficiency transactions, and contract energy management, and strive to make breakthroughs in advancing building energy efficiency. The "Notice" proposed that new public buildings should guide the entire construction process in accordance with the requirements of energy saving, land and green ecology, strictly enforce the mandatory standards for energy conservation in construction projects, and use energy consumption standards as a mandatory threshold for the approval and filing of construction projects. The construction of high-energy-consumption buildings; to promote green design, green construction, and extensive use of natural ventilation, shading and other passive energy-saving technologies. At the same time, to strengthen the control of energy consumption indicators for the construction of public buildings, especially for large-scale public buildings, according to the form, scale, and function of the buildings, sub-item energy consumption indicators should be introduced at the planning and design stages to restrict the building size coefficient, heating and air-conditioning, and ventilation. The design parameters and system configuration of energy-using systems such as lighting, hot water, and domestic hot water avoid the one-sided pursuit of “new, odd, and special” architectural designs, and the energy system design index is too large, causing waste.

In view of the current prominent problems in China's large-scale public buildings such as high energy consumption, strong growth momentum, and slow progress in energy-saving renovation, the two sectors are clear and will effectively increase support during the “12th Five-Year Plan” period, and actively promote energy-saving renovation of key energy-using buildings. Effectively change the situation of high energy consumption in public buildings. On the one hand, implementation of energy-saving renovation of key urban public buildings. The two departments will start a batch of key cities for energy conservation in public buildings. By 2015, the energy consumption per unit area of ​​public buildings in key cities will drop by more than 20%, of which the energy consumption in the construction area of ​​large public buildings will decrease by more than 30%. Renovation of key cities shall complete reconstruction of not less than 4 million square meters within 2 years after approval. For the reform of key cities, the central government will grant financial subsidies. The subsidy standard is, in principle, 20 yuan per square meter, and comprehensive consideration shall be given to the amount of energy-saving renovation, the contents of transformation, and energy-saving effects. On the other hand, it is imperative to promote the energy-saving reform of key public buildings such as colleges and universities and the construction of the central office buildings at this level. It should be clear that the demonstration of energy-saving buildings in universities should not be less than 200,000 square meters, and the energy consumption per unit area should be reduced by more than 20% At the same time, the two departments will co-organize the work of energy-conservation renovation of the central office building at the same level as the State Council Authority and other departments, and grant financial subsidies.

In this regard, Lu Bin, vice president of the Institute of Building Environment and Energy Research of the Chinese Academy of Building Research, believes that the targeted promotion of public building energy conservation will play a significant role in promoting energy conservation and consumption reduction in public buildings, especially large-scale public buildings. . At present, the biggest obstacle to energy conservation in public buildings is the insufficient enthusiasm and initiative in the energy-saving transformation of energy-using units. The issuance of the “Notice” will help improve the enthusiasm of energy-saving units in energy-using units. At the same time, he said that at present, the state has great efforts in energy-saving emission reduction policies, but to ensure the implementation of policies to fully reflect the effectiveness of the policy also requires relevant departments to accelerate the popularization of awareness of public building energy conservation, and strengthen the supervision and management during the implementation of the policy.
