Strengthen Green Building Design Management

•Implement green building design requirements

Newly built civil buildings in urban areas shall be designed in accordance with green building standards, and the schematic design, preliminary design and construction drawing design stages shall include green building-related content.At the schematic design stage,the green building design objectives and main technical measures shall be clearly defined;at the preliminary design stage,the technical options and corresponding indicators for each green building specialty shall be clarified, including the control items, scoring items and bonus-item technical measures of each specialty;at the construction drawing design stage,a dedicated green building chapter (see Appendix 1) and supporting technical documents shall be prepared, and the relevant content shall meet the requirements for equipment and material procurement, fabrication and construction of the project. For the green retrofit design of existing buildings, a dedicated green retrofit chapter for existing buildings (see Appendix 2) and supporting technical documents shall be prepared.Design institutes are encouraged to adopt BIM-based forward design in green building design, and to apply BIM technology for scheme comparison and selection, performance analysis, and drawing output and delivery.    

          

•Implement special green building review

The special green building review system shall be improved. Construction drawing review agencies shall review the green building grade and design content against the key points and relevant requirements for green building construction drawing review, and shall issue a special green building review opinion based on the review results (see Appendices 3 and 4). Where the special green building review is not passed, the construction drawing review agency shall not issue a review approval certificate. Cities (prefectures) are encouraged to compile local key points for green building construction drawing review in accordance with standards and specifications and to organize their implementation.For projects designed with BIM technology, the construction drawing review agency shall use BIM technology to conduct the review.

          

•Strictly manage design changes

The requirements of relevant national laws, regulations and rules shall be implemented. No unit or individual may alter the reviewed and approved green building-related design content without authorization. Where a change is genuinely required, the modified content shall not fall below the local green building grade requirement (based on the time the construction drawing review approval certificate was first obtained), and the modified construction drawings shall be submitted to the original review agency for review as required.

          

Strengthen Green Building Construction Management

•Strengthen construction organization and management

Before project construction,the project ownershall organize the design, construction, supervision and other units to carry out technical disclosure of green building-related content. The construction unit shall, in accordance with relevant standards, specifications and construction drawing design documents, incorporate green building-related content into the construction organization design and implement it.The engineering supervision unitshall supervise green building-related content in accordance with relevant standards, specifications and construction drawing design documents.The engineering quality testing institutionshall carry out green building engineering quality testing in accordance with relevant standards and specifications and issue test reports.Construction units are encouraged to use BIM technology and, based on BIM models, carry out visual simulation of the construction process, optimization of construction schemes and other work.    

          

•Implement sampling inspection requirements

The requirements of current mandatory standards such as the “General Code for Building Environment” GB55016, the “General Code for Building Energy Efficiency and Renewable Energy Utilization” GB55015 and the “General Code for Building Water Supply, Drainage and Water Conservation” GB55020 shall be strictly implemented. Testing shall be carried out on green building air quality, sound insulation performance, lighting effect, air-conditioning performance, water quality and other aspects, and the relevant test results shall serve as green building quality control records.

          

•Strictly supervise engineering quality

Housing and urban-rural development authorities at all levels shall incorporate green building quality management into the “double random, one open” spot checks, and shall, in accordance with the law, handle any discovered acts of design, construction drawing review, construction, supervision or acceptance that violate green building-related provisions and mandatory standards.

          

Establish a Green Building Acceptance System

From September 1, 2024(based on the time the construction permit is obtained), before the completion acceptance of a unit project, the construction project shall carry out special green building acceptance against the current “Sichuan Province Standard for Special Acceptance of Green Building Engineering” DBJ51/T208. The special green building acceptance shall be organized and implemented in the following manner:

          

•Specialty acceptance    

On the basis of the construction unit passing its self-inspection, the project supervision unit shall organize the design, construction and other relevant units to carry out acceptance by specialty, and shall fill in the “Sichuan Province Specialty-wise Acceptance Record Form for Green Building Construction Quality” as required (see Appendix D of the “Sichuan Province Standard for Special Acceptance of Green Building Engineering”). Sub-divisional and sub-item works that have already passed acceptance shall not be accepted again.

          

•Overall acceptance

On the basis of passing the specialty acceptance, the project owner shall organize the design, construction, supervision and other relevant units to accept the overall quality completion of the green building in accordance with the construction contract, relevant standards and specifications, construction drawing design documents and other relevant materials, and shall fill in the “Sichuan Province Special Acceptance Report for Green Building Construction Quality” (see Appendices 5 and 6).

          

Standardize Green Building Evaluation Management

The evaluation of newly built green buildings shall be conducted after the completion acceptance of the building project has been filed. A pre-evaluation may be conducted after the construction drawing design of the building project is completed.

          

•Optimize the pre-evaluation process

The pre-evaluation is implemented by means of “self-assessment + construction drawing review”: on the basis of a self-assessment by the project owner or its entrusted design institute, the project passes the special green building review of the corresponding grade. The pre-evaluation does not confer a green building label certificate. For projects that need to apply for green finance policy support, the local housing and urban-rural development authority shall provide support.

          

•Promote label evaluation and certification

The application for star-rated green building label certification follows the voluntary principle and is submitted by the project owner, the operation unit or the owner entity. Design, construction and consulting units are encouraged to jointly participate in the application for star-rated green building labels.The housing and urban-rural development bureaus (commissions) of all cities (prefectures)shall certify one-star green buildings and grant the label, conduct preliminary review and recommend two-star green buildings, and conduct pre-review and recommend three-star green buildings.The Department of Housing and Urban-Rural Developmentshall certify two-star green buildings and grant the label, and conduct preliminary review and recommend three-star green buildings. The certification process for three-star green building labels shall be carried out in accordance with the relevant requirements of MOHURD. Star-rated green buildings that receive green finance policy support or special funds for urban and rural construction development shall obtain a green building label certificate of the corresponding grade, and other star-rated green buildings are encouraged to apply for green building labels. Cities (prefectures) are encouraged to introduce support policies for star-rated green buildings.    

          

Localities are encouraged to carry out green retrofitting of existing buildings in light of local conditions and to promote the star-rating label certification of existing buildings.

          

Improve Green Building Operation and Management

Green building operation and management shall be strengthened and the operating efficiency of green building facilities and equipment improved. Daily operation requirements such as water saving and energy saving of green buildings are encouraged to be included in the scope of property management contracts. Housing decoration and fit-out activities shall be regulated, and effective measures shall be taken to protect the building envelope, energy consumption monitoring equipment and systems, renewable energy utilization systems and other facilities. Operation units or owners are encouraged to carry out self-inspections of operating conditions with reference to the green building operation self-inspection form (see Appendices 7 and 8). The operation unit or owner of a project that has obtained a green building label shall strengthen green building operation and management, enhance the comparison between operating indicators and the star-rating indicators declared for the green building label, and promptly report the main annual operating indicators to the green building label management information system each year. Where the main indicator data are not reported or are not truthfully reported for more than two consecutive years and the required rectification is not completed, the green building label shall be revoked in accordance with regulations.Operation units are encouraged to use BIM models to carry out operation management.

          

Firmly consolidate the principal responsibilities of all participating parties

The project ownershall strictly fulfill the primary responsibility, incorporate green building-related requirements into the design, construction and supervision contracts, and stipulate the work content and quality of the design, construction and supervision units.The design instituteshall carry out the design in accordance with green building standards, specifications and contract agreements, and prepare green building design documents.The construction unitshall strictly regulate construction activities and carry out construction in accordance with relevant standards and specifications, approved design documents and the construction contract.The engineering supervision unitshall strictly carry out supervision activities and implement engineering supervision in accordance with relevant standards and specifications, approved design documents and the supervision contract.The housing and urban-rural development bureaus (commissions) of all cities (prefectures)shall strengthen the management of the survey, design, construction, operation and other stages of green buildings in their regions, reinforce whole-process quality management, and ensure that all green building technical measures are implemented and effective.    

          

Cities (prefectures) are encouraged, on the basis of implementing this notice and in light of local realities, to formulate detailed measures for whole-process quality management of green buildings.

          

The notice takes effect from September 1, 2024, with a validity period of 5 years.
