Abstract: Green construction and information technology have been made great progress in China. As a quantitative embodiment of green construction effects, green construction evaluation is a direction worthy of research on how to combine with information technology to achieve automatic and intelligent evaluation. This article is based on the Green Construction Guidelines、Evaluation Standards for Green Construction of Construction Engineering (GB/T50640) and Code for Green Construction of Building (GB/T50905), with the help of the green construction monitoring and management platform developed by the research group to build an information model of green construction evaluation index and influencing factors. Combined with the original green construction information model on site, the model can be imported into the platform to assess the green construction effect through comparing indicator data carried by the model and the field data collected by the platform. The results show that each factor makes a difference in its corresponding green construction index. This study analyzes their correlations, which can be used as a reference for the evaluation of green construction and its automatic intelligence.
