Simulation support in designing the transformation of urban building stock and energy infrastructure

The transition of the urban building stock and infrastructure to sustainable forms is a key challenge in modern planning. The purpose of this paper is to propose a simulation model for energy use in the Japanese commercial sector. This model enables a user to consider a variety of energy-management concepts and discuss how urban building stock and infrastructure can be transformed over the coming decades. The model is characterized by having a bottom-up structure, which contributes to improving the reliability of the simulation results. Although the model is not yet complete, we present a case study to demonstrate the simulation capabilities of the model. The results of the case study indicate that the model can be used in support of a design to transform the urban building stock and infrastructure.
