A comparison research is launched for the Indoor Environment Quality indicators of the popular Green Building Assessment systems and China Evaluation standard for green building, including the IEQ indicators’ contents, weightings, and the scoring requirements for different green building ratings. By comparison, it was found that the indoor environment is mainly composed by IAQ, version environment, thermal environment and the acoustic environment, and the IAQ is the most important component in these systems. Although there is no weighting system or scoring system in China Green building assessment system, it is characterized by the relatively numerous prerequisites and the achieved indicators requirement for different ratings. Besides, the indicators paid with intensive attention in these systems are found.
