On October 13, 2021, the Ministry of Housing and Urban-Rural Development officially issued the Sugar baby‘s national strong rule “General Standards for the Application of Building Energy and Renewable Dynamics” GB 55015-2021 (hereinafter referred to as the “Sales Energy Specifications”), which will be implemented from April 1, 2022. This is a national full-text mandatory rule for the field of architecture and renewable dynamic application.
Specifications
1. The full text is strong, and the standard system of the strong engineering construction must be strictly implemented to cover all types of construction projects in the engineering construction field. After the implementation of the standard of the strong engineering construction, the current national standards and industry standards of the relevant engineering construction will be terminated at the same time. The full text of “General Specifications” is strong and must be strictly implemented!
2. General specifications for building energy and renewable power cover wide coverage
Touching and new buildings, existing buildings, renewable power systems, construction and inspection collection and operation management, etc., the design, construction, acceptance and operation management of new buildings, reconstruction and expansion buildings and existing building energy reform projects must implement this specification.
3. Building carbon emissions calculation is a strong request
The General Specifications requests the feasibility study report on construction project goals, construction plans and preliminary design documents should include building energy consumption, renewable power applications and building carbon emission analysis reports. During project divergence stages, carbon emission calculation and analysis are required and strictly implemented.
4. Renewable power application requirements for detailed requirements
Renewable power system has made clear indicators and requests for solar energy applications, air source heat pumps, ground source heat pumps, etc. Solar photovoltaics is the main measure for the construction of the county and achieving dual carbon targets in the next stage. The General Specifications asks that the new building should be equipped with a solar system. When the solar photovoltaic power generation system is designed, the system installation capacity and annual total electricity generation should be provided.
5. The energy design level of new building buildings has improved a step-by-step approach. The “General Specifications” has improved the thermal industrial limit requirements for stilted buildings and public buildings, and has different from the current energy standards in major regions. The degree of even design energy consumption has decreased by 30% and 20% respectively on the basis of the national standards and industry standards of the current energy design.
1) The average energy rate of sunny buildings in severe and cold areas should be 75%;
2) The average energy rate of sunny buildings in other climate areas should be 65%;
3) The average energy rate of public buildings should be 72%.
6. New requirements for industrial building energy design indicators for temperature area industrial building sectors
Compared with the “Single Standard for Industrial Building Energy Design” GB 51245-2017, the “General Specification” adds industrial building energy design indicators for thermal air conditioning systems in Temperature Area A to set up industrial building energy design indicators for thermal air conditioning systems, expand the scope of industrial standards applicable to industrial standards, and strictly implement industrial buildings in Temperature area.
7. The effectiveness of heat-transmission air conditioning system and lighting requirements are comprehensively loaded
The General Specifications provide comprehensive loading for cooling water cooling machines, heat pump systems, multi-connectors and other cooling source equipment machines. The lighting power density compares the current lighting standards, meets the target value requirements, and further reduces the energy consumption of construction operations.
YouGreen Intelligent Bank believes that this specification plays a major role in the overall goal of the construction industry’s response to the 2030 carbon peak and 2060 carbon neutrality, and has a serious reference value for the programming of the “14th Five-Year Plan” program and the determination of the medium-term and long-term carbon reduction target. What are the key points of this rule that are worth paying attention to? What impact will it have on the architectural sector and the renewable dynamic application field? Youluo Smart Bank interprets its key points.

What are the standard for engineering construction?
In order to adapt to the international technical law regulations and technical standard pass rules, since 2016, the Housing and Urban Construction Department has continuously issued the “Opinions on Deepening the Standardized Task of Engineering Construction” and other articles Sugar baby‘s document proposes a long-term goal of voluntarily adopting standards for the bureau and social group system. It is clear that the full-text strong engineering construction specifications will be used instead of the transformation of the current standardized and scattered strong articles, and gradually formed the technical regulations and full-text strengthening in laws, administrative regulations, and departmental regulations.
The “Technical Laws” system is composed of the “Technical Laws” system.
The strong engineering construction specification system covers various types of construction engineering projects in the engineering construction field, and is divided into two types: engineering project specifications (simplified project specifications) and general technology specifications (simplified general specifications). The project specifications are based on the overall engineering construction project,Five major elements, including project scale, layout, efficiency, function and key technology methods, are important content. The general specifications take the various professional general technologies for implementing the effectiveness and function of engineering construction projects as the target, and the general technologies such as exploration, design, construction, maintenance, and maintenance are important content. In the full text, the project specification system is the backbone, and the general specification is the regulation of the individual and general professional key technology regulations for various types of projects.
In accordance with the “Manila” Department of Housing and Urban Construction on Deepening the Standardization of Engineering Construction Tasks Manila escortOpinions (安全全〔〕〕166》) Regarding the system system of constructing a full-text strong engineering construction specification (hereinafter referred to as engineering specifications), the Ministry of Housing and Urban-Rural Development organized China Urban Construction Research Institute Co., Ltd. and other units drafted the “City and Country Water Project Project Specifications” and other 40 project specifications, and publicly solicited opinions from the public in February 2019.
On August 25, 2000, the Ministry of Housing and Urban-Rural Development issued the “Regulations on the Supervision of Implementation Engineering Construction”, and clearly requested “to undertake new construction, expansion, reconstruction and other engineering construction activities within the People’s Republic of China, and must Sugar baby. baby must implement the compulsory standards for engineering construction. “The regulations were revised two times on January 22, 2015 and March 30, 2021, and are still in use to this day.
In 2021, the Ministry of Housing and Urban-Rural Development has issued 37 forced engineering regulations, and all or departmental documents in the regulations must be strictly implemented. At the same time, the Sugar daddy several relevant and compulsory articles on the construction standards of the current project were terminated.
The meaning and planning of “General Specifications for Energy and Renewable Dynamic Applications of Architectural Festivals”
The release of “General Specifications for Energy and Renewable Dynamic Applications of Architectural Festivals” is for the implementationThe country has laws and regulations on dynamics, protection of ecological environments, and climate change, implement carbon peak and carbon neutrality decisions, improve the effectiveness of dynamic resources, promote renewable dynamic applications, reduce building carbon emissions, build a well-developed building indoo TC:
