Abstract: The utilization of sewage heat is a novel concept within the field of renewable energy development, especially the technique of recovering heat through pipelines on a regional scale to maximize reutilization of the heat of buildings. However, the features and utilization potential of sewage heat have not been completely explored to date. It may be possible to develop better reutilization strategies that exploit the heat generated in urban areas and eventually reduce the environmental load. The goal of this study was to develop an estimation methodology and judging criteria based on a proposed urban sewage state prediction model to evaluate and recommend the utilization potential of sewage heat in urban areas. In this paper, an evaluation methodology is introduced through case studies that apply the model to an actual area for evaluating the regional sewage heat utilization potential and clarifying which buildings are appropriate to utilize the sewage heat.
