To plan the preparation of design standards for green rural housing, guide and standardize the construction of green rural housing, improve the construction quality of rural housing, extend the service life of rural housing, improve the residential function of rural housing, and enhance the quality of rural housing. In Lintong District, Chang 'an District and other agriculture-related districts and counties, pilot projects will be carried out to build green rural housing models that are safe, practical, energy-saving, environmentally friendly, economically beautiful, healthy and comfortable.

Third, the implementation of the main responsibility

We will further consolidate the main responsibilities of all parties involved in green building, establish a "closed-loop responsibility" work system with clear responsibilities, and ensure that the construction links of green building projects are closed, the whole process is controllable, and the responsibilities are clear.

(1) Responsibilities of the construction unit. Construction units shall assume the main responsibility for green building construction. When conducting project design, consulting bidding or commissioning design, the grade of green building and related index requirements shall be clearly defined. Strengthen the organization and implementation of the whole process of project construction, perform duties in accordance with policies, regulations and green building standards and specifications, and do not express or imply that the relevant units will lower the green building standards and grades for any reason.

After the construction drawing design review has made clear the grade of green building, according to the needs, design and consulting institutions can be entrusted by themselves to conduct star-level pre-evaluation of green building, and no logo will be awarded.

During the special inspection and acceptance of the project, the design, construction and supervision units shall be organized to conduct self-inspection on the implementation of various green building technical measures of the project, and after forming a qualified self-inspection report of the corresponding level of green building, they shall apply for mid-term special inspection and acceptance of green building to the district and county housing construction administrative departments and the management committee of the development zone.

(2) Responsibility of the design unit. Complete the green building design documents in strict accordance with the green building standards and regulations and the depth of preparation of green building design documents, define the green building related technical measures, conduct self-assessment according to the requirements of different levels, and issue the corresponding technical measures supporting documents. Those that do not meet the design requirements of the corresponding grade of green building shall not be submitted to the construction unit for examination.

(3) Responsibility of the drawing examination institution. In strict accordance with the specific requirements for the comprehensive implementation of green building standards, in accordance with the standards for green building and the key points of examination, the construction drawing design documents submitted by the construction units shall be subject to the special technical examination of green buildings, and the special examination opinions shall be issued to clarify the grades of green buildings and the main technical measures, and those that fail to implement the green building standards in accordance with the provisions or fail to pass the special examination. The certificate of qualification shall not be issued.

(4) Responsibility of the construction unit. Construction shall be carried out in strict accordance with the qualified construction drawing design documents and construction technical specifications, and the special construction organization plan for green buildings shall be prepared. The construction materials, products and equipment used shall conform to the requirements of the construction drawing design documents, and the selection of building materials products certified as green building materials shall be encouraged. The construction materials, products and equipment used in construction shall be inspected, and samples shall be sent to qualified testing institutions for reinspection in accordance with regulations to ensure that the performance indicators meet the standard requirements.

(5) Responsibilities of the supervision unit. In accordance with the regulations and requirements of green building standards and qualified construction drawing design documents, supervise the construction activities and witness the sampling and inspection of the construction site. Those who arbitrarily alter the design content of the construction drawings for green buildings, fail to carry out construction in accordance with the examined and qualified construction drawing design documents, or use building materials, products and equipment that do not meet the requirements of the green building standards shall be stopped, and those who fail to stop shall be promptly reported to the local competent construction administrative department.

Fourth, strengthen supervision and management

We should do a good job in the supervision and management of green buildings throughout their life cycle, improve the comprehensive closed management mechanism of all links including design, drawing review, construction, acceptance and operation, and improve the management of green building identification to ensure efficient and stable operation of green buildings.

1. Strengthen front-end supervision of projects.

(2) Do a good job of green building identification. The municipal administrative department of housing construction shall do a good job in identifying and awarding one-star green buildings. The district/county administrative department of housing construction and the administrative committee of development zone shall do a good job in the cultivation, recommendation and preliminary examination of star-rated green buildings in accordance with the green building identification procedures (see annex).

(3) To find out the bottom of the implementation of the "four Qing". We will focus on the four key links of the design, construction, acceptance inspection and filing of the completion of new buildings, and establish four lists of green building construction projects to be started, under construction, acceptance inspection and filing, so as to ensure that the project base is clear, construction responsibilities are clear, implementation is accurate, and supervision responsibilities are real, so as to ensure that green building development and construction tasks are completed with high quality.

(4) Carrying out daily inspections and inspections. We will continue to focus on projects, establish a regular inspection mechanism, and carry out supervision and inspection of design, drawing review, construction, acceptance inspection and operation. For units that have violated regulations, we will establish a list of problems, and follow up and supervise them through stoppage of work for rectification, individual interviews, centralized review, and special report until the number is cancelled.

5. Doing a good job in management, training and guidance. Relying on the resource advantages of universities and research institutes in our city, we will continue to carry out the service activities of "three, four lectures and two interactions" on building energy conservation, focusing on the policies, regulations and technical standards of green buildings, energy consumption statistics, renewable energy application, green ecological residential areas, green farm houses and other aspects, summarize and promote replicable experience and practices, and create a good atmosphere for all parties to pay attention to and promote development.

This notice shall be implemented as of the date of issuance.
