Abstract
Due to the global warming and vulnerability of energy supply recognized by The Great East Japan Earthquake, it is required for the regional renewal considering not only introduction of individual low carbon technologies but also urban spatial structure. This study aims to construct the evaluation method of renewal focusing on environmental load reduction and emergency energy supply. Estimated results show possibility of drastical reduction of CO2 emissions by the combination of introduction individual technologies and energy security improved by electric power and heat supply. Also, it become to derive the optimal size of the energy facility to utilize this method.
