AbstractOutdoor thermal comfort is crucial in sub-tropical regions where summer heat stress impede outdoor space usage. Research on the effects of environmental perception on thermal comfort has increased in recent years as a result of intensified urban development and it has been found that urban geometry design can modify the relationship between climate and thermal comfort. Despite this, there is a lack of holistic studies focusing on the effects of qualities of urban space on thermal adaptation and comfort. This study investigates the relationship between environmental perception and outdoor thermal comfort under typical summer conditions in streets and parks in Hong Kong by conducting questionnaire survey on thermal sensation and environmental perception in terms of convenience, visual and acoustic comfort, air quality and safety. Simultaneous micrometeorological measurements were also conducted to obtained objective conditions of thermal comfort in designated urban spaces. A total of 1921 responses were collected between June 2017 and September 2017 in 12 locations. Overall, we found that environmental perceptions, particularly the perceived air quality, acoustic comfort and visual comfort, significantly affect thermal sensation and comfort. Improved perception of each investigated environmental parameter could lead to a substantial increase in the percentage of people feeling thermally comfortable.
