Question 3: During the 14th Five Year Plan period, what are the scope and standards of incentive funds for ultra-low energy consumption building projects and energy-saving and green transformation projects in Beijing?

Answer: According to the "Implementation Rules for the Management of Beijing Building Green Development Incentive Fund Demonstration Project (Trial)" (Beijing Jianfa [2023] No. 191), the scope and standards of rewards for ultra-low energy building projects: For the entire ultra-low energy building demonstration project with a construction area of 1000 square meters or more and passing the special acceptance of ultra-low energy buildings, a maximum of 200 yuan per square meter will be given based on the implemented construction area A municipal level financial reward with a maximum reward of no more than 6 million yuan for a single demonstration project.

The rewards for energy-saving and green transformation projects in public buildings should comply with: (1) public buildings with a single building area of 3000 square meters or more within the administrative area of this city; (2) Incorporate into the management of energy consumption quotas for public buildings in this city; (3) Large public buildings with a single area greater than 20000 square meters need to fill out an energy utilization status report as required; (4) Projects that have been included in the management system of public building energy-saving and green transformation projects of the Municipal Housing and Urban Rural Development Commission from January 1, 2019 to December 31, 2020 or completed after January 1, 2021 (5) achieve an energy-saving rate of no less than 15% for ordinary public buildings, no less than 20% for large public buildings, or meet the requirements for converted area. For one or more energy-saving renovations to the heating, ventilation and air conditioning systems, power systems, power supply and distribution and lighting systems, monitoring and control systems, enclosure structures, and water supply and drainage systems of public buildings that have achieved an energy-saving rate of 15%, and for large public buildings that have achieved an energy-saving rate of 20%, a municipal reward fund of no more than 20 yuan per square meter will be given to projects that have passed the comprehensive acceptance of the District Housing Urban Rural (City) Construction Committee, The total amount of municipal reward funds for a single demonstration project shall not exceed 30% of the renovation investment.

Q4: What are the special requirements for the acceptance of ultra-low energy buildings?

Answer: The acceptance of ultra-low energy consumption buildings should include the quality acceptance of energy-saving engineering construction and air tightness testing. The construction quality acceptance of energy-saving engineering in ultra-low energy residential buildings should be carried out in accordance with the provisions of the "Technical Specification for Construction Quality of Energy Saving Engineering in Ultra Low Energy Residential Buildings" DB11/T 1971. The construction quality acceptance of ultra-low energy consumption public building energy-saving projects should be carried out in accordance with the "Technical Guidelines for Beijing Ultra Low Energy Consumption Demonstration Projects" or the construction and acceptance regulations for ultra-low energy consumption public building energy-saving projects in Beijing; The airtightness test should be carried out in accordance with the requirements of Appendix E of the "On site Inspection Standard for Energy Efficiency Engineering of Civil Buildings" DB11/T 555 or the "Technical Standard for Near Zero Energy Consumption Buildings" GB/T 51350.

Question 5: How to apply for municipal financial reward funds for energy-saving and green transformation of public buildings?

Answer: For projects that have been in trial operation for 12 months after the completion and acceptance of the renovation (qualified), the applying unit should log in to the "Public Building Energy Conservation and Greenization Renovation Project Management System" of the Public Building Energy Conservation Management Service Platform on the official website of the Municipal Housing and Urban Rural Development Commission, and submit the business license (legal person certificate), enterprise social credit code, building property ownership certificate or real estate registration certificate through the system Power of Attorney (non property owner declaration), renovation project plan, renovation project contract, energy utilization status report, certificate of inclusion in the public building energy consumption limit management platform, application for municipal incentive funds for public building energy-saving and green renovation projects (see Annex 1), commitment letter, renovation completion acceptance form, calculation of energy-saving quantity (rate), and implementation report of energy-saving renovation projects Relevant supporting materials such as proof of investment in renovation. Immediate declaration and acceptance. The specific process is detailed in the "Implementation Rules for the Management of Beijing Building Green Development Incentive Fund Demonstration Project (Trial)" (Jing Jian Fa [2023] No. 191).

Question 6: What is the idea for the energy efficiency grading management of public buildings in our city? What is a Level 5 energy efficient public building?

Answer: Our city is the first in the country to implement energy efficiency classification management for key public buildings. The Work Plan for Establishing and Improving the Methods and Systems for Energy Efficiency Evaluation of Public Buildings in Beijing (Jingfa Gai [2023] No. 479) has been issued, and energy efficiency evaluation of public buildings will be carried out in different fields and stages; Implementing differentiated management, public buildings in our city are divided into five levels based on their energy efficiency level. The first level of energy efficiency is the optimal level, and public buildings in the fifth level should take measures to improve their energy efficiency level according to relevant requirements; Exploring the application scenarios of energy efficiency grading in public buildings and implementing the public energy intensity benchmarking system for public buildings, exploring the inclusion of Level 5 energy efficiency public buildings in the differentiated energy pricing system and the pilot scope of energy rights trading.

According to Jing Fa Gai [2023] No. 479, the revised local standard "Energy Consumption Indicators for Civil Buildings" (DB11/T 1382) in Beijing will clarify the energy consumption constraint value per unit building area (the upper limit value of the building energy consumption indicator allowed to achieve building usage functions, i.e. Ec) and guidance value by type On the premise of achieving the functional use of buildings, comprehensively and efficiently utilize various building energy-saving technologies and management measures to achieve the expected value of building energy consumption indicators with higher building energy-saving effects, i.e. El. According to the local standards, the energy efficiency level of public buildings is divided into five levels, with the first level being the optimal level and the fifth level being the constraint value where the energy consumption per unit building area exceeds 1.8 times.
