Abstract: For green buildings, the effect of energy-saving potential evaluation using the current method is poor and the evaluation efficiency is low. This paper uses the entropy weight method to study the energy-saving potential evaluation method of green buildings. Firstly, the evaluation index system of energy-saving potential of green buildings is established under the principles of scientificity, systematicness and operability, and the evaluation indexes are obtained. Then the entropy weight method is used to determine the index weight and calculate the energy-saving potential index. Finally, the energy-saving potential is evaluated based on the value on the basis of analysing the economic benefits. The simulation results show that the accuracy of the proposed method for energy-saving potential evaluation is up to 100%, the evaluation time is within 5 s, the evaluation accuracy is the highest and the evaluation time is the shortest.

Keywords: entropy weight method; economic performance; judgment matrix; G value.
