description	The aging of the population requires creating conditions for the elderly to live with quality. Buildings' thermal comfort is essential to achieve this goal. This research analyzes the Predicted Mean Vote (PMV) and its extension (PMVe) to assess elderly women's thermal comfort conditions, aged 60 years or above. The study was conducted in two naturally ventilated senior homes in Santa Maria, RS, region with a temperate climate and hot summer. The study measured air temperature, air relative humidity, globe temperature, and air velocity. The study also performed a data survey on the perception and thermal preferences, clothing, and metabolic activity of the elderly. Then, the comfort sensation index was calculated. Users' thermal sensation was compared with PMV and PMVe, considering expectation factors of 0.5, 0.7, and 0.9. Comparing the three PMVe values, we could estimate that the lower the expectation factor, the smaller the difference between the PMVe and the negative thermal sensation votes (cold). The PMVe with correction factor 0.5 presented a perfect correlation for the PMV variables and the thermal sensation to 11.54% of the measurements. In contrast, the PMVe of 0.7 and 0.9 showed no points over the correlation reference line. The study demonstrated that the PMV extension does not correct the PMV inaccuracies but reduces the thermal sensation's differences, reducing the cold sensation overestimation of PMV results for elderly women.

O envelhecimento populacional torna necessário criar condições para que idosos vivam com qualidade de vida. O conforto térmico das edificações é fundamental para atingir essa meta. Esta pesquisa analisou a aplicabilidade do Voto Médio Estimado (PMV) e a sua extensão (PMVe) para avaliação do conforto térmico de idosas, com idade igual ou superior a 60 anos. O estudo foi aplicado em dois residenciais geriátricos naturalmente ventilados localizados em Santa Maria, RS, região de clima temperado com verão quente. As variáveis ambientais temperatura do ar, umidade relativa do ar, temperatura de globo e velocidade do ar foram medidas e foram aplicados questionários para o levantamento da sensação e preferência térmicas das idosas e das variáveis vestimenta e atividade metabólica. Então, calculou-se o índice de sensação de conforto. A sensação térmica real dos usuários foi comparada com o PMV e o PMVe, com fatores de correção de 0,5, 0,7 e 0,9. Comparando os três valores de PMVe, estimou-se que, quanto menor o fator expectativa, menor é a diferença entre PMVe e sensação térmica para valores negativos (frio). O PMVe com fator de correção 0,5 apresentou perfeita correlação das variáveis PMV e sensação térmica relatada em 11,54% das medições, já o PMVe de 0,7 e de 0,9 não apresentaram nenhum ponto sobre a reta de referência. O estudo mostrou que a extensão do PMV não corrige as imprecisões do modelo, mas reduz as diferenças encontradas com os valores de sensação térmica relatada, diminuindo a superestimação da sensação de frio que o PMV resultava para as idosas.
