1.0.1 Building activity is one of the activities with the largest impact on natural resources and environment for human. Our country is in the stage of rapid economy development; the annual building quantity is ranked first in the world, and the total resource consumption amount is increasing rapidly year by year. Therefore, we must implant and earnestly implement scientific outlook on development, persist in sustainable development concept, and greatly develop green building. The green building development shall implement the national technical and economic policy with respect to resource conservation and environmental protection. This standard is formulated to specify the evaluation for green building and push the development of green building.
1.0.2 For buildings with different types, the conditions of resource consumption and environment impact have relatively large difference due to their different use functions. In consideration of the current market construction condition of China, this standard emphasizes particularly on evaluating residential buildings with large total amount, and office buildings, commercial buildings and hotel buildings with more energy resource consumption in public buildings. The evaluation for other buildings may refer to this standard.
1.0.3 The building, from planning & design to subsequent construction, operation and final dismantlement, forms a whole life cycle. Paying attention to the whole life cycle of the building means not only fully considering and utilizing environmental factors in planning & design stage and ensuring minimum environment impact during the construction process; the operation stage is capable of providing healthy, comfortable, low-consumption and unharmful activity space for human and minimizing the environmental hazard after dismantlement. Green building requires, within its whole life cycle, maximum energy conservation, land conservation, water conservation, material conservation and environmental protection, and meets the building function. These are incompatible each other sometimes, for instance, redundantly utilize water in order to place undue emphasis on the housing estate landscape, redundantly consume materials in order to reach single index of energy conservation, these do not meet the green building requirements; however, the reduction of functional requirements and applicability of the building is not advocated by green building even though it may consume fewer resources. The contradiction among energy conservation, land conservation, water conservation, material conservation and environmental protection must be completely considered and correctly treated in the whole life cycle of the building, meanwhile, the application of information technology and intelligent technology as well as new technology, new product, new material and new process of green building shall also be appreciated.
1.0.4 The climate, geographic environment, natural resources, economic development, social custom, etc. of different areas of China have large difference; when evaluating green building, pay attention to territoriality, adjust measures to local conditions, be practical and realistic, and take full consideration of the characteristics of the building location, such as climate, resource, natural environment, economy and culture.
