| Abstract: | In the global context of climate change, outdoor spaces are of vitally importance to a sustainable city, as they accommodate pedestrian traffic and outdoor activities, plus the great contributions to urban vitality and the city living quality. However, the factors affecting microclimate at outdoor spaces are a complex issue comprising both urban meteorology, urban geometry and building morphology aspects. Current investigations are limited within a specific discipline, and most research are concern at the perspective of pedestrian-level wind velocity and lack the understanding and quantitative assessment of the thermal comfort around different outdoor spaces under different microclimate. This study presents the findings of consecutive day's experiments about outdoor thermal environment in different seasons, based in Hong Kong, a typical sub-tropical city of China. Four typical meteorological parameters (air temperature, globe temperature, relative humidity and wind velocity) are monitored in four characteristics campus site. The research is focus on the joint influence of meteorological parameters and building morphology on outdoor thermal conditions. Moreover, ENVI-met software simulation was used to estimate the microclimate of the study area, on-site experiment data and simulation data were compared to confirm the accuracy of ENVI-met calculation. The operative temperature (Top) and thermal sensation vote (TSV) are been used as the thermal sensation inIIdex to evaluate the comfort conditions. Conclusions are thus addressed for architects' and city planners' reference in the future urban design. |
