China Code green building certification:

Green buildings refer to the buildings which combines resources saving and environment protection within the complete life circle. And although excess utilization of a single technique can improve performance in certain aspect, it may result in new waste. Therefore, the effect between building size, building technology and investment shall be overall evaluated from each stage of the complete life circle of buildings. Based on the main purpose of saving resources and protect environment, take safety, durability, economics, appearance and other factors into general consideration, and compare and confirm optimal technology, materials and equipment.


In creating green buildings, the planning, design, construction and finalizing phases shall be taken under control. Each responsible party shall follow the requirements of evaluation indicators of this standard, set goals, clarify responsibilities, control the processes, and finally produce reports on control over the processes of planning, design, construction and finalizing. The party which applies for evaluation shall submit basic materials regarding process control for evaluation, as required by green building evaluation institutes. Green building evaluation institutes will analyze the basic materials and issue evaluation reports as on-site project inspection is considered.


4.1 Introduction

Green building evaluation indicators system refers to a complete description of green building functions according to definition. It can be used to evaluate differences between as-built buildings and definition-based green buildings in terms of functions. Take international experience in green building evaluation systems as reference, emphasize on energy-saving, land-saving, water-saving, materials-saving and environment protection, as far as regional, economic and social situations of our country are concerned, and build a China-featured green building evaluation indicators system.

Green building evaluation indicators system consists of six indicators, viz land-saving an outdoor environment, energy-saving and energy utilization, water-saving and water resources utilization, materials-saving and materials resources utilization, indoor environment quality and operation management. Currently basic data for green building evaluation in our country are not sufficient. For example, as for data of energy consumption in production process of all building materials, emission amount of CO2, fixed amount of CO2 of all different vegetation and trees, there lacks corresponding databases, which makes the standard for quantitative evaluation hard to define scientifically. As a result, those terms that are not mature or impossible to be quantitative now will not be included here. As further development of related basic research, the evaluation will be gradually improved.

Each indicator contains controlling options, general options and prior options. Controlling options are mandatory conditions for green buildings; general options and prior options are optional conditions for classifying green buildings, while prior options refer to those for great difficulty, intensive integration and high degree of green coverage.

There are totally 76 controlling options, general options and prior options for residential buildings, where there are 27 controlling options, 40 general options and 9 prior options. As for public buildings, there are totally 83 controlling options, general options and prior options, where there are 26 controlling options, 43 general options and 14 prior options.

Besides satisfying all controlling options, one-star, two-star and three-star shall also satisfy the requirements of general options and prior options in the list.

When certain article in the standard is not applicable to the conditions of a building, like the region, climate and building type, the article can be excluded from evaluation. Then total options involved in evaluation will accordingly be reduced, and requirement for the number of options can be adjusted proportionally.

4.2 Work Process


1)         Application Submission includes declaration of project, the self-assessment report and documents of proof.


2)         Formal Review includes company qualification of the declaration, the integrity of declaration materials, the name and category standardization of electronic folders, and reviewing display and name of files. 


3)         "Professional evaluation" means that the professionals of Green Building Evaluation Label review the self-evaluation report.


4)         Professionals finish "professional evaluation report of the green building (design) evaluation”.


5)         "Expert evaluation" means that members of "green building assessment expert committee" verify and confirm the results of materials and professional evaluation.


6)         The project reviewed by experts will be shown 30 days in the websites of Ministry of Housing and Urban-rural (, Development Center of Ministry of Housing and Urban-rural Development of Science and Technology (, and Chinese Green Building Label (

7)         If other companies or individuals have objections for the project, they can put forward the written opinions to Ministry of Housing and Urban-rural, and Development Center of Ministry of Housing and Urban-rural Development of Science and Technology.


8)         If nobody has no objections, Ministry of Housing and Urban-rural will issue an announcement and award the certificate or logo and of “Chinese Green Building Label”.
