Abstract
With the rapid development of district energy system, a relatively perfect evaluation system becomes a top priority in making a promising system with multiple complementary functions recognized by the government and the public. Based on the characteristics of district energy, the district energy evaluation index system is established from energy efficiency, economy, and environment. Traditional evaluation indicators have been filtrated and optimized. The indicators adopt an improved analytical hierarchy process to determine the weights. The reference district energy system grading standard is presented in view of the score of the relevant energy system. Finally, the proposed evaluation system is used to assess an actual project. The results show that the proposed evaluation system has good maneuverability and can guide the optimization of the system.
