AbstractIn high-density cities, the highly variable environmental conditions within short walking distances result in a considerable influence on pedestrians’ thermal comfort when they travel within the urban environment. Conventional studies adopted the “static” approach which is insufficient to consider the transient nature, and hence requires a new approach to incorporate the dynamic response of human thermal comfort to inform urban geometry design. This study aims to investigate how people’s thermal sensation and pleasure respond to the changing environmental conditions. Subjects were asked to perform two walking routes with thermal sensation vote (TSV) and thermal pleasure vote (TPV) asked at designated points. Meteorological parameters were measured for the calculation of physiological equivalent temperature. Parameters of urban geometry were also acquired from field measurements and geographical information system. Results showed that TSV and TPV showed remarkable differences under partially cloudy and clear sky conditions. Their relationship also showed the possible effect of thermal alliesthesia due to the higher magnitude of response of TPV. Results of the autocorrelation analysis implied the existence of potential thresholds for the level of tolerance to unfavourable thermal conditions. Further work includes the design of walking routes to define such thresholds and the development of practical design recommendations.
