Determining the Impact of Microclimatic Variables on Human Comfort; A Case Study of Akure Urban Environment, Nigeria | Chapter 3 | Challenging Issues on Environment and Earth Science Vol. 7

The physiological equivalent temperature (PET) index was used in this study to assess differences in physiologic comfort of people living in the Akure metropolitan setting using a Geographic Information System (GIS). PET values were calculated from both microclimatic and thermophysiological data using the Rayman model, which may provide mean radiant temperature and PET, which are important in thermo-physiological heat balance models. It also looked at the responses of a sampled population to various land uses, which was the major goal of the study. the study: that is, to examine the geographical pattern of human comfort in the study region using a physiological equivalent temperature index across various land use types. As a result of diverse activities in each of the land uses evaluated, thermal heat stress was discovered geographically and temporally (6:00; 12:00; and 18:00 local standard time, LST) within the research area as high as (41-55) °C. The results also revealed that many of the respondents had not yet grasped the concept of thermal stress. as well as the consequences. The study's conclusion is that data should be collected during the dry season and that tree planting and urban greenery should be improved.
