By using multi-standards analysis, 66 existing District Heating and Cooling (DHC) systems in Japan have been evaluated from three viewpoints of business profits, energy-saving and environmental protection, amenity and safety, respectively. From the relative importance of above three viewpoints, the business profits was most emphasized; while from the relative importance of evaluation items of viewpoints, heat charge (A5), integrated COP (Bl), heating storage capacitance (C2) of 1 Kcal energy are most emphasized. Priority sequence of 5 categories which generated from integrated evaluation is 3, 4,1, 2,5. Evaluation results of 22% samples are good, while that of 6% samples are bad. In addition, compared with results from simple linear summation, the integrated evaluation results of multi-standards are proved to be right. Based on the evaluation results proposed in this paper, we can find the problems and corresponding improvement solution in existing DHC systems.
