MEASUREMENT OF HEAT TRANSFER AND EVALUATION OF THERMAL COMFORT IN URBAN STREET AREA

– Measurement in summer season at Midosuji Osaka city –

Abstract

Recently, heat island phenomenon becomes remarkable in big cities, and different countermeasures for mitigation of the phenomenon are adopted. In order to proceed the measures effectively build comfortable stay space in urban area where land use is limited, it is important to understand the conditions of heat transfer in urban area and the physiology reaction in outdoor space. In this study, thermal environment at pavement of Midosuji street is measured and thermal comfort in the area is evaluated by subject experiment.WBGT index is applied for evaluation of sense of heat received from street area.
