Abstract: The urban area development has intensified the urban heat island effect in Hong Kong. Constructions could obstruct and weaken the incoming wind and further trap the air and surface temperature in a dense concentration of buildings. Some studies are conducted to predict the UHI intensity of different districts in Hong Kong, but none focus on the actual temperature difference between rural and urban areas. Research on the impact the UHI effect brings to several districts in Hong Kong has been done in this study. I discovered that rural areas in Hong Kong are generally 3-5°C lower than urban areas.
Some studies investigated the thermal comfort of people under different conditions, but those only focused on one angle or type of respondents. This study conducted on-site meteorological measurements and questionnaire surveys of 54 human subjects on a university campus in Hong Kong between October 2021 and January 2022. I have investigated the influence of gender, acclimatization and circadian rhythm on outdoor thermal comfort. First, it was discovered that females were less tolerant of the cold environment while feeling more comfortable in a hot climate than males. Second, local respondents reported a higher comfort level in a cold environment than non-locals. However, non-local respondents were more adoptive to the high temperature in Hong Kong. Lastly, there was no significant difference between the thermal comfort of the morning and afternoon sections under a cold climate. Yet, respondents were less adaptive to the hot weather in the afternoon than morning. This investigation could help build an understanding of the difference in thermal comfort of different people and provide a reference for architects to examine the thermal comfort requirements.
