Due to rapid urbanization, most cities has been developed without considering the outdoor thermal comfort. As a result, many problems occur in urban area such as wind chill effect in winter and heat island effect in summer.
Recently, rising interest in urban environment for sustainable community, many research results for outdoor thermal environment were suggested. However, proceeding researches were focused on heat island in urban area. In these days, we suffer from unexampled cold climate in winter and need to reconsider the conventionla outdoor design guidelines.
In this study, new outdoor thermal comfort index and assesment methods were proposed. New outdoor thermal comfort index, CSDH(Cold Sense Degree Hour) and HSDH(Hot Sense Degree Hour) is based on SET*, can be calculated with local climate data. In this paper, the concept of the CSDH and HSDH was described. The outdoor thermal comfort for 10 main city in Korea were calculated and compared with the result for Hong Kong.
