| description |
Despite the aging of the population in general and in particular in Brazil, there is not yet research on the thermal perception of Brazilian elderly. The available information is based on studies conducted in climates very different from those in Brazil. This study's purpose was to evaluate if there are significant differences in the thermal perception of the elderly in comparison with younger subjects. In an air-conditioned room, there were measured their thermal variables and applied a questionnaire to a sample of elderly. The answers to the questions about the reported thermal perception (TP), thermal comfort and preference, personal acceptability and tolerance, were related to the respective operational temperatures and with those calculated by the PMV (reference for non-elderly population). The mean operative temperature for neutrality (TP = 0) was lower than those calculated by the PMV, i.e., smaller than preferred by non-elderly; furthermore, the range of operative temperature for thermal comfort for elderly is also wider than for non-elderly. These results diverge, in principle, from those found in the international literature, by finding lower comfort temperatures for the elderly than for the non-elderly, but they may be supported by more recent studies involving circadian thermometry. Other answers to the questions show that PMV is not a good predictor of thermal comfort conditions for the elderly. As this is the first work on the subject in Brazil, it opens a discussion and invites researchers to carry out similar studies to verify its validity. |

Apesar do envelhecimento da população de forma geral e, em particular, no Brasil, não há até o momento pesquisas sobre a percepção térmica do idoso no país. As informações disponíveis são baseadas em estudos realizados em climas diversos dos brasileiros. O objetivo do presente trabalho foi avaliar se existem alterações significativas na percepção térmica de idosos em relação à de indivíduos mais jovens. Numa sala com ar condicionado foram medidas suas variáveis térmicas e aplicado um questionário a uma amostra de idosos. As respostas a questões sobre percepção térmica relatada pelos sujeitos (PT), conforto e preferência térmica, aceitabilidade e tolerância pessoal foram relacionadas com as respectivas temperaturas operacionais e essas com as calculadas pelo PMV (referência para não idosos). A temperatura operativa média de neutralidade (PT = 0) foi menor que a calculada pelo PMV, ou seja, menor do que a preferida por não idosos; além disso, a faixa de temperatura operativa de conforto térmico de idosos é também maior que a de não idosos. Os resultados divergem, em princípio, dos encontrados na bibliografia internacional, ao encontrar temperaturas de conforto para idosos menores do que para não idosos, mas eles podem ser amparados em trabalhos mais recentes, os quais envolvem termometria circadiana. Outras respostas ao questionário mostram que o PMV não é um bom previsor de condições de conforto térmico para idosos. Como este é o primeiro trabalho sobre o tema no Brasil, ele abre uma discussão e convida pesquisadores a realizar estudos similares para sua validação.
