A comparative study is addressed between China GBL and some typical foreign Green Building Assessments, including BREEAM, LEED and CASBEE, focusing on the contents, weight system and requirement for Land Use. Through comparison, it has been found that site selection, land utilization, ecology environment are the main components of Land Use (hereafter referred to as LU). The land utilization occupied the most scores than the summation of other factor in LEED, The ecology environment occupied the most scores than the summation of other factor in CASBEE, and still the land utilization and ecology environment occupied the most scores in BREEAM and China GBL. Meanwhile, also found several common indicators being paid attentions in all GABSs. Besides, China GBL is characterized with its large amount of prerequisites than the other GBASs, and the requirements on Land Use category becomes stricter responding to higher green building labels.
