Until now, there is still no world-wide uniform definition to it and individual evaluation sys-tem for energy-efficient buildings has its own emphasis. In China’s Evaluation Standard for Green Building (GB/T 50378), “Green building refers to the buildings that can maximally save resources (energy, land, water and material), protect the environment, reduce pollution, provide healthy, comfortable and efficient use space as well as be harmoni-ous with the nature in the whole lifecycle.” The empha-ses are laid on resource-saving and environmental protec-tion. For the moment, there are several internationally rec-ognized green building evaluation or certification systems such as LEED (Leadership in Energy Environmental De-sign, USA), BREEAM (Building Research Establishment  Environmental Assessment Method, Britain), CASBEE (Comprehensive Assessment System for Building Envi-ronmental Efficiency, Japan), DGNB Certificate (G
