“…Objective environmental parameters include temperature, humidity, wind speed and radiation intensity. Subjective individual differences include gender [11][12][13][14][15], age [16], [17], body shape [13], [15], region [18], [19], clothing thermal resistance [20], activity intensity [21][22][23]. There are few studies on the thermal environment of college students during the period of lockdown and quarantine.…”

In order to understand the influence of the lockdown of COVID-19 on the thermal comfort of college students' dormitories, the temperature and humidity inside and outside the dormitories of a university in the severe cold region in spring were tested on site. At the same time, the environmental conditions and students' emotional state in college students' dormitories were investigated in the form of online questionnaires. Taking PMV as the overall evaluation index of thermal comfort, the linear regression equations of MTS and PMV were obtained by weighted regression analysis of MTS, PMV and air temperature. By analyzing the relationship curve between TSV and TCV, it can be seen that the comfort in the thermal environment is higher than that in the cold environment, and students are more inclined to the hot environment. The results of the questionnaire showd that during the period of COVID-19 lockdown, college students stayed in the dormitory for a long time, with little activity intensity, and a few students had irritability. Most students do not fully realize that indoor air quality can be adjusted by adaptive behavior, such as intermittent opening of doors and windows, increasing the opening of doors and windows. The regression equations of indoor residence time, exercise intensity and emotional state with TSV and TCV were fitted, and their effects on TSV and TCV were analyzed. It can be seen that the indoor residence time had no significant effect on TSV and TCV during the lockdown period. Low-intensity activity is conducive to indoor thermal comfort in spring, and human thermal comfort and thermal sensation are the best in a calm emotional state. This study is conducive to improving the thermal environment of college students' dormitories during the lockdown period, improving the comfort of dormitories, and preparing for the isolation of public health emergencies in the future.

“…Constatou-se que a neutralidade é a faixa na qual ocorrem as maiores discrepâncias entre os dados obtidos. Os resultados indicam que existem diferentes respostas fisiológicas ao ambiente térmico, relativas a cada faixa de idade investigada (WAN et al, 2022).…”

Xvii Encontro Nacional De Conforto No Ambiente Construído

O envelhecimento da população brasileira suscita investigações que proporcionem caracterização da população idosa em relação ao ambiente térmico. O aumento das médias de temperatura do ar, influenciadas pelas mudanças climáticas, afetam diretamente o conforto térmico dos indivíduos. Sendo que, especialmente os idosos estão propensos a vulnerabilidade térmica tendo em vista as alterações fisiológicas acarretadas pelo avanço da idade. Investigar a interação entre variáveis de conforto e percepção térmica permite ampliar as decisões relativas ao bem-estar desta população. Assim, esse estudo, procurou caracterizar as inter-relações entre a ventilação externa, ventilação interna e a temperatura do ar interna e o impacto dessas variáveis ambientais na percepção de conforto térmico em idosos em climas tropicais distintos. A coleta de dados foi realizada em unidades habitacionais unifamiliares construídas especificamente para abrigar idosos. Elas estão localizadas nas cidades de João Pessoa, Campina Grande e Cajazeiras, estado da Paraíba, locais de clima quente-úmido e semiárido. A ventilação influenciou diretamente a temperatura do ar e a percepção de conforto térmico de idosos. Considerando a percepção de conforto térmico e a ventilação interna, quando registradas velocidades do ar acima de 0,9m/s a probabilidade de resposta favorável ao conforto é de 75,0%. Este estudo apresentou que os idosos possuem significativa sensibilidade à velocidade do vento, associando-a ao conforto térmico.
