Abstract: Outdoor thermal comfort has become a public concern relevant to human health. The outdoor spaces in Hong Kong, which is a sub-tropical city, is less used due to thermal discomfort. Thermal sensation is not only affected by microclimate but also thermal adaptation, which involves physiological, psychological and behavior factors. In order to make outdoor spaces more comfortable to pedestrian and to make outdoor environment pleasant for people to use and enjoy, better understanding of the thermal sensation of people is needed. This paper presents the field measurements and questionnaire survey results of an outdoor thermal comfort study conducted in Hong Kong Polytechnic University, which reveals wind speed, relative humidity, air temperature and globe temperature. The physical measurement was dealt with based on PMV (Fanger), PET and SET* using a software called RayMan. The results of questionnaire survey were correlated with the micro-meteorological data to analyze the general outdoor thermal comfort conditions on campus. The results showed that outdoor thermal comfort varies due to the wind modification and shading effects including the position and distribution of building blocks. Some suggestions were achieved by a better understanding towards constructions affecting human thermal perception in Hong Kong. This understanding makes a contribution towards building designers and planners for creating a more thermally comfortable outdoor space in hot and humid tropical and sub-tropical cities.
