This study aims to evaluate agreement among subjective thermal comfort, thermal sensation, thermal perception, and thermal tolerance indices, according to pedestrians in downtown Santa Maria, southern Brazil, which has a humid subtropical climate (Cfa). Between August 2015 and July 2016 (three periods), 1728 questionnaires were applied. Evaluation of the dependence of statistical variables was based on gender and age, at three periods of time: August 2015 (864 respondents), January 2016 (432 respondents), and July 2016 (432 respondents). Statistical evaluation was based on Pearson's chi-square test using RStudio software, and a significance level (α) of 5% for thermal comfort, thermal sensation, thermal preference, and thermal tolerance was used. Results indicated that age and gender affect the relationship between the variables. Thermal comfort and thermal tolerance presented the best correlation and coherence, regardless of age or gender. This study contributes to knowledge on the local microclimate and can contribute to urban planning to implement strategies that improve pedestrians' thermal comfort.
本研究旨在评估主观热舒适度、热感觉、热知觉和热耐受指数之间的一致性，研究对象为巴西南部圣玛丽亚市（Santa Maria）的行人，该城市属于湿润亚热带气候（Cfa）。2015 年 8 月至 2016 年 7 月（三个时期），共发放了 1728 份问卷。评估统计变量的依赖性基于性别和年龄，在三个时间段进行：2015 年 8 月（864 名受访者）、2016 年 1 月（432 名受访者）和 2016 年 7 月（432 名受访者）。统计评估基于 RStudio 软件中的 Pearson 卡方检验，热舒适度、热感觉、热偏好和热耐受的显著性水平（α）为 5%。结果表明，年龄和性别会影响变量之间的关系。无论年龄或性别如何，热舒适度和热耐受都呈现出最佳的相关性和一致性。本研究有助于了解当地的小气候，并能为城市规划提供改善行人热舒适度的策略。
