集合住宅地における街区の空間形態および構成材料と全表面からの顕熱流量との関係の考察

抄録

In this study, the relationship between the form and materials of urban blocks and sensible heat flux from the total surfaces was analyzed for the case of 'Tama New Town' which is one of the largest housing estates in Japan and is now under development. First, urban blocks were divided into 5 categories from the point of plot types of buildings. The characteristics of the form and thermal properties of each building, as well as land cover condition (area of vegetation, bare soil, asphalt pavement, and built area) of each category was considered. Furthermore, 6 urban blocks were selected for numerical simulation of heat balance of the total surfaces, and sensible heat flux from the total surfaces of each urban block on clear sky day in summer was calculated. It was clarified that the influence of buildings' directions and floor area ratio was as great as buildings' materials upon the amount of sensible heat flux in each urban block.
