Thermal effects of environmental variables on people in open air : Part I, review and experomental studies

There are many instances in which a human body is exposed to a windy climate: on a veranda, at an outdoor-restaurant, in a courtyard, etc. The comfort sensations of a human being are very susceptible to environmental variables. However, few comfort criteria for outdoor thermal environments have been established, even though many research projects for indoor climate have been completed. In this part of the paper, subjective experiments in open air and in a wind tunnel are mentioned. Based on experimental results, the effects of solar radiation, activity level, and the turbulence of air velocity on subjective sensations were analyzed. Comfort criteria for outdoor thermal environments will be proposed in the next part
