Assessment standard for green building
1 General provisions
1.0.1 In order to implement the concept of green development, promote the
high-quality development of green buildings, save resources, protect the
environment, meet the people's growing needs for a better life, this standard is
formulated.
1.0.2 This standard applies to the assessment of the green performance of civil
buildings.
1.0.3 The assessment of green buildings shall follow the principle of adapting
measures to local conditions, combining the characteristics of the climate,
environment, resources, economy and culture of the area where the building is
located, to make comprehensive assessment of such performances as safety,
durability, health and comfort, living convenience, resource conservation, and
environmental livability.
1.0.4 The site design and architectural layout of green buildings shall be
combined with the topography and geomorphology; the architectural layout
shall be adapted to the climatic conditions and geographical environment of the
site; the wind environment, light environment, thermal environment, acoustic
environment of the site shall be organized and utilized.
1.0.5 In addition to complying with the provisions of this standard, the
assessment of green buildings shall also comply with the provisions of relevant
national standards.
2 Terms
2.0.1 Green building
A high-quality building which, during the whole life cycle, saves resources,
protects the environment, reduces pollution, provides people with healthy,
applicable and efficient use of space, maximizes the realization of harmonious
coexistence between man and nature.
2.0.2 Green performance
It involves the comprehensive performance of building safety and durability,
health and comfort, living convenience, resource saving (land saving, energy
saving, water saving, material saving) and environmental livability.
2.0.3 Decorated
Before delivery, all interior walls, top surfaces, floors of residential buildings are
paved and painted, doors and windows, fixed furniture, equipment pipelines,
switch sockets, kitchen and toilet fixtures are installed in place; all fixed surfaces
in public areas of public buildings are paved and painted; basic equipment such
as water, heating, electricity and ventilation are all installed in place.
2.0.4 Heat island intensity
The difference between the temperature in an area of a city and the temperature
in the suburbs, expressed by the difference between the temperature at the
representative measurement points of the two, which is the characterizing
parameter of the urban heat island effect.
2.0.5 Green building material
The building materials which, during the whole life cycle, can reduce the
consumption of resources and reduce the impact on the ecological environment,
has the characteristics of energy saving, emission reduction, safety, health,
convenience and recyclability.
3 Basic requirements
3.1 General requirements
3.1.1 The green building assessment shall take a single building or a group of
buildings as the assessment object. The assessment object shall implement
and deepen the green development requirements as put forward by the upper-
level statutory planning and related special plans; the systematic and holistic
indicators shall be evaluated based on the overall situation of the engineering
project to which the building belongs.
3.1.2 Green building assessment shall be carried out after the completion of the
construction project. Pre-assessment can be carried out after the construction
drawing design of the construction project is completed.
3.1.3 The assessment applicant shall conduct full-life technical and economic
analysis of the participating buildings; select appropriate technologies,
equipment and materials; control the entire process of planning, design,
construction, operation; submit corresponding analysis and testing report and
related documents during the assessment. The party applying for assessment
shall be responsible for the authenticity and completeness of the submitted
The concentration reduction basis is the relevant requirements of the
current national standard "Indoor air quality standard" GB/T 18883.
