“…However, to date no study has investigated children's thermal perception in different building construction types, which is particularly relevant for the case of primary school children which have been found to have a different thermal sensation compared to adults [17][18][19]22]. This has also been highlighted in previous work by the authors in naturally ventilated classrooms of a junior school, which showed that children had a higher sensitivity to high temperatures than adults [18,23].…”

“…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. A smaller number of studies investigated children's thermal comfort in primary schools [16][17][18][19] or included primary schools in the school sample [20,21].…”

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.

“…A rather small number of studies have focused on primary school children (Humphreys, 1977, Mors et al, 2011, Teli et al, 2012, De Giuli et al, 2012, Haddad et al, 2014, Trebilock and Figueroa, 2014 to secondary school children (Auliciems, 1969, Auliciems, 1973, Humphreys, 1973, Kwok and Chun, 2003, Wong and Khoo, 2003, Corgnati et al, 2007, Hwang et al, 2009, AlRashidi et al, 2009, Liang et al, 2012 or both primary and secondary combined (Auliciems, 1975, de Dear et al, 2015, d'Ambrosio Alfano et al, 2013. This analysis focuses on primary school children, as differences between primary and secondary could impact on children's thermal adaptation.…”

“…Given the different thermal perception of children found from pupil surveys (Mors et al, 2011, Teli et al, 2012, Teli et al, 2013, de Dear et al, 2015, Haddad et al, 2014, Trebilock and Figueroa, 2014, these values need to be compared against children's responses. The analysis presented in this paper helps to understand the thermal response of pupils to indoor temperature changes through 'day-survey' analysis for the estimation of 'G', assuming that no or minimal adaptation has occurred.…”

Thermal comfort surveys in school classrooms suggest that children have different thermal preferences to adults. This implies a need to revisit the current adult-based thermal comfort models. This paper investigates the principal adaptive comfort relationships which form the basis of adaptive comfort theory, using 2,693 pupil thermal sensation responses and measured classroom temperatures from surveys in two naturally ventilated school buildings. The data were examined in two steps: firstly, each survey set; obtained over 1-day visits to the schools; was examined in order to derive the relationship between indoor temperature change and comfort vote with minimum impact of adaptation. Secondly, the dataset was investigated over the entire survey period, in relation to the weather experienced by the pupils in order to estimate their time for adaptation to outdoor temperature changes. The analysis shows that the basic adaptive comfort relationships are valid for children. However, a difference was found for the correlation coefficients of the comfort temperature to the outdoor running mean temperature between the schools, and a mismatch between their adaptive comfort equations. It is proposed that the difference in the consistency of the weather during the tests is the main reason for this discrepancy.

Mine refuge chambers are used to shield miners who fail to escape from the mine when incidents occur. Environment maintaining system plays a key role in stabilizing thermal environment of a mine refuge chamber against heat emitted from metabolism and transferred from outside. The safety and comfort of refugees are closely related to the environment maintaining system design. In order to improve the comfort of refugees, optimization on the environment maintaining system has been done based on the previous work. To evaluate the environment of the chamber, eight volunteers were involved into the experiment. Under close observation and safety protection, they lived in a heat-isolated test chamber for 106 hours. The volunteers were asked to maintain low level of activities to simulate refugees' situation. It shows that the environment maintaining system worked well and the temperature, relative humidity and emitted harmful air content such as CO 2 and CO were all kept in the safety level, and no discomfort was felt by volunteers at all.
