Outline of Final Research Achievements

Various low-carbon measures have been proposed as countermeasures to global warming. However, to achieve these measures, they must be compatible with the living environment of the residents. Therefore, we evaluated the impact of the introduction of low-carbon measures on the urban thermal environment. In this research, evaluations were performed using a coupled urban canopy and building energy model. Results showed that in many CO2 reduction measures through energy conservation, a temperature-lowering effect was present. However, with photovoltaic installation, temperature increased slightly.
