Abstract
The purposes of this study was to understand the influences of microclimate on user’s thermal comfort in the urban park, and furthermore to investigate the influences of personal characteristics on thermal comfort. Field surveys were performed in the garden road, playground, eco-pond, lawn and pavilion of the urban park which in the sun and in the shade. Microclimate data were measured including air temperature, horizontal solar radiation, relative humidity and wind speed. Personal characteristics and assessments of microclimate in the moment with thermal sensation, comfort and acceptability were investigated by structured questionnaire. Statistical methods including T-test, One-way ANOVA, correlational analysis, correlation ratio and regression analysis were used to test the hypotheses and establish the thermal comfort predicting model with microclimatic, environmental and personal factors. The major results are summarized as follows: The layout and shading of each site were significant influences on air temperature, solar radiation, relative humidity and wind speed. There were significantly correlations in thermal comfort with air temperature and solar radiation. Thermal sensation were significantly influence the assessments of comfort and acceptability, and there were medium correlationships within thermal sensation and comfort and acceptability. In personal parameters, a siginificant negative correlation were found between age and thermal sensation, and the activity type were significant influences on assessments of comfort and acceptability. The results of the multiple regression analysis showed that air temperature, solar radiation, site planning and age had the most significant influence on the predictive model of thermal sensation.
