Abstract

The aging of the Brazilian population raises investigations that characterize the elderly population concerning the thermal environment. The increase in average air temperature, influenced by climate change, directly affects the thermal comfort of individuals. Older people are especially prone to thermal vulnerability because of the physiological changes brought about by advancing age. Investigating the interaction between comfort variables and thermal perception allows expanding decisions related to the well-being of this population. Thus, in this study, an attempt was made to characterize the interrelationships between external ventilation, internal ventilation, and internal air temperature, allowing the evaluation of the impact of some environmental variables on the perception of thermal comfort in the ancients in different tropical climates. Data was collected in single-family housing units specifically to house older people. They are in João Pessoa, Campina Grande, and Cajazeiras, the state of Paraíba, with hot-humid and semi-arid climates. Ventilation directly influences the air temperature and the perception of thermal comfort. Considering the perception of thermal comfort and internal ventilation, when velocities are above 0.9 m/s a, the probability of a favorable response to comfort is 75.0%. This study showed that older people are more sensitive to wind speed, associating it with thermal comfort.
