The Regulations of Guangzhou Municipality on the Management of Green Building and Building Energy Efficiency is a formal project of Guangzhou Municipality's 20 12 government regulation making plan, which was drafted by Guangzhou Municipal Construction Committee and reviewed by Guangzhou Legislative Affairs Office. The draft Regulations of Guangzhou Municipality on the Management of Green Building and Building Energy Efficiency was deliberated and adopted by the executive meeting of Guangzhou Municipal Government on March 1, and will be formally promulgated and implemented in the near future. The Regulations of Guangzhou Municipality on the Management of Green Building and Building Energy Efficiency is divided into seven chapters and 52 articles, mainly including general principles, construction process management, use process management, incentive measures and so on. Its main system and innovation are embodied in the following aspects:
First, take the lead in incorporating the management requirements of green building construction into legislation.
The Regulations of Guangzhou Municipality on the Management of Green Building and Building Energy Efficiency first specifies in Article 11 that four types of buildings must implement green building standards, and then integrates the relevant indicators and requirements of green buildings into the whole process of construction projects, and establishes a green building construction management system. In addition, combined with the future development trend, a series of innovative measures to promote the large-scale development of green buildings are put forward, such as: requiring new urban areas to prepare special plans for regional energy utilization and water resources utilization, and implementing them in control regulations; In order to guide the effective implementation of green buildings, a green building completion sign system was established. Introduce international advanced concepts and advocate the construction of green data centers; For green buildings with more than two stars (including two stars), the plot ratio is calculated according to the new method to encourage the construction unit to develop and build green buildings.
The second is to innovate and improve the whole process management system of building energy conservation.
The Regulations of Guangzhou Municipality on the Management of Green Building and Building Energy Efficiency runs through the whole process of engineering construction, and strengthens management in eight links, including project establishment, land use planning permission, land use approval, energy-saving design, construction management, process supervision, completion acceptance and operation management, and extends building energy efficiency management to the early stage of project establishment and planning, and establishes a linkage management mechanism involving multiple departments such as development and reform planning.
Third, the work of building energy conservation will be extended to industrial buildings.
With the industrial transformation and upgrading, the proportion of high-tech industries and light industries is increasing, and the building energy consumption of such industrial enterprises is increasing. Therefore, it is imperative to extend the work of building energy conservation to industrial buildings. Our city took the lead in passing legislation to require some industrial buildings to implement green energy-saving standards.
Four, the whole process management of public building energy consumption control indicators into legislation.
The Regulations of Guangzhou Municipality on the Management of Green Buildings and Building Energy Efficiency stipulates that public buildings with high energy consumption should not only implement mandatory building energy efficiency standards, but also control the design, acceptance and operation of the project through energy consumption quota indicators to quantify the actual effect of energy saving.
Five, large public buildings put into use after the implementation of energy monitoring.
Article 17 of the Regulations of Guangzhou Municipality on the Management of Green Buildings and Building Energy Conservation clearly states that "for newly-built and energy-saving national office buildings and large-scale public building projects, the construction unit shall install energy consumption itemized metering devices networked with the energy consumption monitoring platform of public buildings in this Municipality before the project acceptance." According to the calculation, the energy consumption of buildings can be reduced by 10-20% by strengthening the energy-saving management of building operation. Therefore, Guangzhou has grasped the characteristics of relatively high energy consumption of large public buildings and easy to realize unified management, and established an energy consumption monitoring platform by itemizing the electricity consumption of different functional systems such as air conditioning, electricity and lighting, which has three functions: (1) For the owners, they can keep abreast of the building energy consumption. (two) for the energy conservation supervision department, it can always grasp the energy consumption of the monitored object, and implement management measures such as building energy audit, mandatory energy conservation transformation, and energy consumption exceeding the limit; (3) For energy-saving service enterprises, energy-saving transformation measures can be formulated according to the monitoring data, and the effect of energy-saving transformation can be reasonably analyzed and evaluated.
Six, 12 floors below the new residential buildings and public buildings with central heating water should be installed with solar hot water.
Article 16 of the Regulations of Guangzhou Municipality on the Management of Green Building and Building Energy Efficiency stipulates that "newly built residential buildings with floors below 12 (including 12) and public buildings with central heating water such as hospitals, dormitories, hotels and swimming pools shall be designed and installed in a unified way. If the installation conditions of solar hot water system are not available, other renewable energy technical measures can be adopted instead. " Geographically and climatically, Guangzhou is located at 23 north latitude, with large surface solar radiation, long sunshine time and abundant solar energy resources. It belongs to the third kind of solar energy resources and is suitable for popularizing and utilizing solar hot water. In addition, the solar hot water utilization system has mature technology and high cost performance, and it has the conditions for large-scale promotion. Therefore, our city has learned from the successful experiences of many domestic cities (Nanjing, Shenzhen, etc.). ), and restrict new residential buildings below 12 floor (considering the basic installation conditions of solar collectors) and public buildings such as hospitals, dormitories, hotels and swimming pools. , realize the centralized hot water supply with stable hot water demand, and uniformly install the solar hot water system.
Seven, building energy-saving materials and product management will be included in the comprehensive evaluation system of building system enterprise integrity.
Article 14 of the Regulations of Guangzhou Municipality on the Management of Green Building and Building Energy Efficiency clearly states that "the municipal construction administrative department shall incorporate building energy-saving materials and products into the comprehensive evaluation system of enterprise integrity of the construction system, formulate the recommended catalogue of building energy-saving materials and products in this Municipality according to the national and provincial promotion catalogues of building energy-saving materials and products and the actual situation of this Municipality, and encourage the construction units to give priority to recommending the building energy-saving materials and products in the catalogue". Strengthening the quality management of building energy-saving materials and products is an important guarantee for implementing building energy-saving. To this end, the Ministry of Housing and Urban-Rural Development issued the Notice on Strengthening the Quality Supervision and Management of Building Energy-saving Materials and Products in 2008, clearly proposing that all localities should implement the filing system of building energy-saving materials and products. Through filing, we can effectively grasp the material information of the use link, the management department conducts spot checks according to the filing information, establishes a credit evaluation mechanism according to the spot check results, and publicly publicizes unqualified products, which can reduce or even eliminate unqualified products. According to the national and provincial building energy-saving promotion catalogue and the integrity evaluation system, Guangzhou has formulated the recommended catalogue and updated it regularly, which can effectively guide the construction market to choose high-quality products.
Eight, green building projects can declare the completion mark.
Article 30 of the Regulations of Guangzhou Municipality on the Management of Green Building and Building Energy Efficiency clearly stipulates that "the municipal construction administrative department shall issue a corresponding grade of green building completion sign for any project that has been implemented in accordance with the technical measures specified in the green building design sign during the construction process and passed the completion acceptance". At present, the national and provincial evaluation of green buildings is divided into green building design logo and green building operation logo, which stipulates that "green building design evaluation logo" should be carried out after the project construction drawing design is completed and passed the construction drawing review and filing; "Green building operation evaluation logo" should be carried out one year after the project is completed and put into use. Judging from the actual development of national and provincial green building evaluation signs, there are two problems: first, the design signs are only drawings, but in the actual construction process, it is often impossible to ensure the implementation of green building design technical measures because of engineering changes; Second, it took one year to apply for the operation logo, and due to the change of owners, incomplete preservation of process data, lack of corresponding incentive mechanism and other reasons, the enthusiasm for applying for the operation logo was not high. In fact, the current marking system lacks an intermediate link, which is a key link-the completion link. Guangzhou creatively established a green building completion sign system. In the future, after the green building projects in our city pass the completion acceptance, we can declare the green building completion sign to the municipal construction administrative department. This move will help raise public awareness of green buildings and promote green buildings to effectively reflect the actual connotation of "four festivals and one environmental protection".
