Requirement Definition of Smart Community in Japan

Inventory of requirement and evaluation of energy and environmental performance by simulation

Abstract

Smart community has received a lot of attention as model district of decarbonizing society. However, requirement definition of smart community is not clear yet. In this paper, the definition of the smart community is discussed through Japanese case analysis. As a result, requirement definition of smart community has been organized into three categories of energy, social function, and information and communication technology. In the latter part of the paper, index of energy performance of smart community is proposed. These are the degree of attainment of net zero energy community, CO2 emission, cost, load ratio of electric power system, and self-consumption rate of the PV generation etc. Example of these evaluation is performed for a model smart community by simulation. In addition, the long-term change of the energy demand considering life stage change is revealed.
