1. General Provisions
1.0.1 For the purposes of going through with the energy conservation and environment protection policies, promoting sustainable development and standardizing the evaluation of green building, this national standard is formulated hereof.
1.0.2 This national standard is designed to evaluate the residential buildings and parts of public buildings like office buildings, commercial buildings and hotel buildings.
1.0.3 When evaluating the green building, the dialectical relation among lifecycle, energy conservation, land conservation, water conservation, material conservation and building functions shall be considered entirely.
1.0.4 When evaluating the green building, the evaluation shall be involved with climate, resource, natural environment, economic and cultural conditions shall be incorporated on the base of the local conditions.
1.0.5 Besides this national standard, the evaluation of green building shall be compliant to the national laws, regulations as well as relevant standards, presenting the consolidation of economic benefit, social benefit and environmental benefit.

Green building refers to the buildings that can maximally save resources (energy, land, water and material), protect the environment, reduce pollution, provides healthy, comfortable and efficient use space as well as be harmonious with the nature in the whole lifecycle.
2.0.2 Heat Island Index
The difference between the air temperature in an urban district and that in the suburb meteorology survey point is the characteristic parameter of heat island effect.
2.0.3 Renewable Energy
Renewable energy refers to the non-fossil energies that can be acquired from the nature and can be regenerated, including wind energy, solar energy, hydraulic energy, biomass energy, geothermal energy and ocean energy, etc.
2.0.4 Nontraditional Water Source
Nontraditional water sources refer to the water sources that are different from the traditional surface water source and groundwater source, and cover regenerated water, rainwater and seawater.
2.0.5 Reusable Material
Reusable materials refer to those materials that can be reused directly or through recombination and re-restoration under the precondition that the shape of the recovered matter is constant.
2.0.6 Recyclable Material
Recyclable materials refer to those materials that cannot be reused but can generate other kind of material through changing the shape of mater and realize multiple times of cyclic utilization.
