“…In particular, in a similar study conducted with children and elementary school students (not older than 11 years), the ranges of children's thermal comfort were different from those of adults depending on differences in physical conditions, clothing insulation, and metabolic rates [16,21]. Through studies on the difference between the thermal comfort of children and adults, researchers have therefore modified the PMV model, based on differences in metabolism [8,22,23].…”

“…A number of studies conducted in tropical [4] and subtropical [5][6][7] locations compared the results from secondary school surveys with the ASHRAE standard 55 [8] thermal comfort model. Al-Rashidi et al [9] investigated secondary school children's thermal sensation in classrooms in hybrid air-conditioning mode. In general, most thermal comfort studies in schools have focused on secondary schools [4][5][6][7][10][11][12][13][14][15], differentiating the school sample in terms of climate or ventilation type.…”

Recent thermal comfort research in a light-weight junior school building showed that children were more sensitive to higher temperatures than adults and subsequently that current thermal comfort standards were not appropriate for the assessment of their thermal environment. This paper presents a comparison of these survey results to those from a survey conducted in a medium-weight school building, in order to evaluate the role of the construction type on the results. Both surveys followed the same methodology, including thermal comfort questionnaires and measurements of indoor environmental variables. A total of 2990 responses were gathered. The buildings had an average difference in air temperature of 2.7 o C during occupied hours in the period of investigation (June and July 2012), with the medium-weight building being cooler than the light-weight building. However, the different construction type and the cooler overall thermal environment in the medium-weight school building had little impact on the pupils' overall thermal sensitivity. The comparison showed a general agreement on the pupils' warm thermal sensation trends, interpersonal variation and undeveloped adaptive behaviour. The results further support the finding that current thermal comfort criteria lead to an underestimation of pupils' thermal sensation during summer.

“…[5][6][7][8][9] On the other hand, there are studies which suggest that the model could be a good predictor of actual mean votes (AMVs). 3,10,11 For example, van der Linden et al 3 showed that the PMV model was well able to explain the results derived from the adaptive thermal comfort (ATC) approach for a moderate maritime outdoor climate as in the Netherlands. Another study conducted in Kuwait classrooms with the hybrid air-conditioned systems indicated that the PMV model was more suitable than other thermal comfort indices to predict the children thermal sensations.…”

The study was conducted to investigate thermal adaptation and the impact of individual differences on developing thermal tolerance when the outdoor temperature falls below 10°C. The applicability of the predicted mean vote (PMV) model was investigated, too. The concept of occupant’s ‘Temperament’ was evaluated as a psychological-adaptation factor. Two main hypotheses were: (a) people with different temperaments would experience different thermal sensations and (b) the classic PMV- predicted percentage dissatisfied (PPD) model is capable of predicting the neutral sensation in heated buildings under cold outdoor temperatures. There was a direct relationship between individual temperament and clothing level as well as thermal sensation. The occupants who were assessed to have cold temperament tend to wear thicker clothes and were more sensitive to variations in indoor air temperature than others. Females with a cold temperament were more than twice as likely to be affected by indoor air temperature as those with a warm temperament. The PMV-PPD model was able to predict the mean neutral temperature in the heated buildings even when the outdoor temperature fell below 10°C. However, when occupants were able to control high indoor temperature, the percentage of true prediction of actual mean votes by the adaptive thermal heat balance model was more than that by the classic PMV model.
