Oneobservation is that the ESGB is more comprehensive than the LEED rating system.In particular, it has a category of requirements addressing the issues of operation ofbuilding. Also, in material use credits, the ESGB is focusing on how to reduce theconsumption of construction materials by means of effective structural design, e.g.high strength steel and concrete or light structure. The requirement of LEED onthis issue, however, is mainly on encouraging reuse old building and recyclematerials. It has no requirement on materials use reduction.As most of the standards or designs required by the ESGB had made reference tothe relevant Chinese standards, it makes the implementation easier in China. Thelocal designers can provide the designs accordingly. Yet, some credits are difficultto achieve. For example, the provision of 30% window vision pane with operanabewindow is difficult to comply with for office building and requires dueconsideration at planning stage. As shown in Fig 6, natural ventilation design canachieve this and will perform better when high-level openings are provided.617
