Construction Standards and Codes in 2011" (Jian Biao [2011] No.17), this standard is
prepared on the basis of revision of the previous national standard GB/T 50378-2006
Assessment Standard for Green Building by China Academy of Building Research, Shanghai
Research Institute of Building Sciences (Group) Co., Ltd jointly with organizations
concerned.
In the revision of this standard, standard drafting group made an extensive investigation
and study, summarized implementation and practical experience of GB/T 50378-2006
Assessment Standard for Green Building over the past few years and made reference to

monographic studies, extensive solicitation for the parties concerned and continuous
discussion, coordination and modification for the specific contents..
This standard consists of 11 chapters, including. general provisions, terms, basic
requirements, land saving and outdoor environment, energy saving and energy utilization,
water saving and water resource utilization, material saving and material resource utilization,
indoor environment quality, construction management, operation management and promotion
and innovation.
The main changes in this revision include.
1. The scope is extended to any civil building from the office buildings, shopping mall
and hotel building in the residential building and public buildings.
2. Assessment consists of design assessment and operation assessment.
3. As for the assessment index system of green buildings, "construction management" is
added besides land saving and outdoor environment, energy saving and energy utilization,
water saving and water resource utilization, material saving and material resource utilization,
indoor environment quality and operation management.
4. Adjust assessment methods. Each assessment index is scored and the green buildings
grade is determined depending on the total score provided that the scoring item for each
assessment index meets the minimum score requirements. The general terms and optimal
items in GB/T 50378-2006 Assessment Standard for Green Building are combined and
