Destruction of the global environment is typically embodied in big urban complexes through removal of natural ecosystem and a large quantity of energy consumption. This research project aims to develop a numerical model system for the assessment of urban thermal environment related with the urban canopy structure and energy system. For this purpose, three kinds of sub-models have been developed, expressing thermal conditions of a building, the canopy layer in a section of city, and the mesoscale region surrounding the city, respectively.
Several series of observation have been carried out to catch meteorological properties around buildings in different city blocks. In particular, the observation at a business building in the downtown area of Tokyo was continued over one year, during which the data of electric and thermal energy supplied to the building were also obtained. These data have been analyzed to clarify the their characteristics and relationship, and used for the verification of the model system. The relationship between energy consumption and urban thermal environment has been simulated, and the result agreed well with the observed data. Therefore, the model system can be expected for application to the assessment of various countermeasures for urban heating.
