Evaluation standard for green construction of building and municipal engineering

1 General

1.0.1 This standard is formulated to promote green construction and standardize the evaluation methods for green construction building and municipal engineering.

1.0.2 This standard is applicable to construction engineering such as new construction, expansion, renovation, and demolition and green construction evaluation of building and municipal engineering such as roads, bridges, and tunnels.

1.0.3 In addition to the requirements of this standard, the evaluation for green construction of building and municipal engineering shall also meet the requirements of the current relevant national standards of the nation.

2 Terms

2.0.1
green construction
construction activity that prioritizes people, adapts to local conditions, and maximizes resource conservation and reduces negative environmental impact through scientific management and technological progress, while ensuring basic requirements such as quality and safety

2.0.2
prerequisite items
required terms that must be met during the green construction

2.0.3
general items
implement provisions with moderate difficulty and requirements during the green construction

2.0.4
extra items
implementation of difficult and demanding clauses during the green construction

2.0.5
construction trash
architectural engineering and waste materials generated during the construction of municipal engineering such as roads, bridges and tunnels
2.0.6
building waste
portion of construction trash that loses its value for recycling and utilization on the construction site after classification

2.0.7
percentage of recovery and reuse
proportion of construction trash recycled and utilized at the construction site to the total construction trash at the construction site

2.0.8
obdurate ground water lowering
precipitation method in which water interception measures are taken in the basement and the side wall of excavation, which will not affect the groundwater level outside excavation

2.0.9
informative construction
construction activities that use information technology to collect, transmit, process, utilize and store information in the implementation process of engineering projects

2.0.10
green construction evaluation
activity to judge the green construction level and effect of engineering construction projects
