Thermal Comfort in Outdoor Environment

摘要

Relatively few studies on thermal comfort for outdoor environments have been done compared to indoor environments, although the importance of the former is increasingly recognized with changing climate and increase of heat stress in cities. The difficulty in assessing thermal outdoor conditions is that the climatic variables are much more diverse than in indoor settings. Indices such as SET~*, PMV and PET are the most broadly used not only as indoor indices but also as outdoor comfort indices. In the present study, applications of these indices to outdoor conditions are reviewed. There remain problems in the assessment of outdoor comfort indices, however, SET~*, PMV and PET have proven suitable for application at the current state of the art.
