With the rapid development of green buildings world widely, it was found that the real performance of green buildings was not as good as expected. This paper presents a case study in China by applying a holistic approach which integrated system dynamics and energy performance simulation in order to evaluate the building performance gap and provide management strategies to minimize the performance gap. The case study in this paper is an office building located in Shanghai, which was awarded “Three Star” by Evaluation Standard for Green Building in China. Thirteen scenarios were carried out in this study which included eight single management strategy scenarios and five multiple management strategy scenarios. In each scenario, both qualification and quantification results were generated. It was found that the building performance could be improved by 33.6%, which was equivalent to 4.3 kWh/m2 of energy saving, by improving team alignment and applying the integrated design strategy.
