3.1.3 The applicant for green building assessment shall conduct the technical and economic analysis on the buildings during the whole life cycle, select appropriate technologies, equipments and materials, control the whole process of the planning, design, construction and operation, and submit corresponding analysis and test reports as well as related documents. The applicant shall also be responsible for the authenticity and integrity of the submitted assessment materials.
3.1.4 The assessment organization shall verify the analysis, test reports and related documents submitted by the applicant, issue an assessment report and specify the grade.
3.1.5 Buildings applying for green financial services shall be calculated and explained in terms of energy saving measures, water saving measures, building energy consumption and carbon emissions, and shall form a special report.
3.1.6 For green buildings, a dedicated design plan for green building shall be provided in the construction drawing design stage, and a green building user manual shall be provided at the time of delivery.
3.2 Assessment and Rating
3.2.1 The assessment index system of green building shall consist of five categories of indexes: safety and durability, health and comfort, occupant convenience, resources saving and environment livability. Each category of indexes includes prerequisite items and scoring items. The assessment index system is also uniformly provided with bonus items.
3.2.2 The assessment result of the prerequisite items shall be “pass” or “fail”; the assessment result of the scoring items and the bonus items shall be score.
3.2.3 As for a multi-functional and comprehensive individual building, the applicable areas shall be assessed in accordance with all the provisions specified in this standard one by one to determine the score of each provision.
3.2.4 The scores of green building assessment shall be in accordance with the requirements specified in Table 3.2.4.

Note: No score for articles 6.2.10, 6.2.11, 6.2.12, 6.2.13, and 9.2.8 of this standard in pre-assessment.
3.2.5 The total score of the assessment of green building is calculated using the following equation:
Q = (Q0+Q1+Q2+Q3+Q4+Q5+QA)/10 (3.2.5)
Where
Q —— the total score;
Q0 —— the basic score of the prerequisite items, which is scored 400 points when all the prerequisite items are passed;
Q1 ~ Q5 —— the scores of the scoring items of five categories (safety and durability, health and comfort, occupant convenience, resources saving, and environment livability);
QA —— the score of bonus items for promotion and innovation.
3.2.6 Based on the rating from low to high, the green buildings shall be divided into four grades: basic, one-star, two-star and three-star.
3.2.7 When the requirements of all prerequisite items are met, the green building grade shall be the basic grade.
3.2.8 The star grade of green building shall be rated according to the following requirements:
1 Green buildings of one-star, two-star and three-star shall meet the requirements of all prerequisite items in this standard and the score for scoring items of each category of index shall not be less than 30% of its full score;
2 Green buildings of one-star, two-star and three-star shall be decorated, and the quality, selected materials and product quality of decorated projects shall meet the requirements of the current relevant standards of the nation.
3 When the total score reaches 60 points, 70 points, 85 points respectively and meanwhile the requirements specified in Table 3.2.8 are met, the green buildings are rated as the grade of one-star, two-star and three-star respectively.
