Here, we propose a new energy supply system for the urban renewal area of Nagoya, which would create a safer, more eco-friendly city. The reduction of greenhouse gas emissions and improved earthquake measures to maintain energy supply systems and a reliable energy supply have not been studied in sufficient detail. In the present study, we focused on emergency generators within buildings in urban areas and the surplus capacity of district heating and cooling (DHC) plants as unutilized energy sources. Combined heat and power systems (CHPs) can be used in both emergency situations and under normal conditions. Thus, we propose replacing emergency generators with highly efficient CHPs and networking them as a new method for organizing an energy supply system that contributes to increases in both eco-friendliness and the safety of the city in the event of earthquakes. We also discuss the surplus capacity of district heating and cooling (DHC) plants as parts of the network. We examine a case study in an urban area of Nagoya, and calculate the effectiveness of our proposal.
