| Abstract: | This study investigates the outdoor thermal comfort in urban street canyon in winter period. The inter-relationships among thermal comfort, thermal sensation, and thermal acceptability is being revealed in this paper. In addition to meteorological factors and physiological factors, the psychological impacts which affect human thermal perceptions by perceiving different urban features, such as canopy and arcade, in street canyon are also being investigated in this paper. The study was conducted by using the combination of qualitative (i.e. questionnaires) and quantitative (i.e. measurement of meteorological parameters) method concurrently in two different urban street canyons of Hong Kong. The collected data was used to formulate a path model to reveal relationships among thermal comfort, thermal sensation, and thermal acceptability, and how the perceived amount of an urban feature such as canopy and arcade of a respondent affected thermal perceptions in a street canyon. Thermal comfort and thermal acceptability are affected by thermal sensation directly. Perceived microclimate (r = 0.227), microclimate (r = 0.171), and perceiving urban features (r = 0.115) show an indirect effect to thermal comfort through thermal sensation, while personal characteristics (i.e. age and clothing value) shows a relatively weak impact to thermal comfort. Thermal acceptability in street canyon might also be improved if the individuals consider themselves perceiving the urban features (r = 0.122), such as canopy and arcade, as a wind block or sun block in winter. The findings provided a relatively new insight on how to make use of urban features psychologically to improve thermal comfort during winter. More investigation is suggested to be done in this direction, we believe that it can be further developed into one of the considerable factors in urban planning or rehabilitation. |
