The relationship between classroom temperature and children’s performance in school

Perceived air quality and cognitive performance decrease at moderately raised indoor temperatures even when clothed for comfort

“…They described the performance of the Stroop task by a U‐shaped curve with linear effects below and above an optimum range of indoor temperature (22°C‐23°C). This is consistent with the relationship developed by Lan et al, 7 Seppänen et al, 6 and Wargocki et al 12 who all found that lower temperatures are more favorable for performance. This conclusion was supported by the findings of Lee et al, 44 who assessed attention by measuring brain waves and found an increase at a lower temperature (20.5°C) compared with a thermally comfortable temperature (24.0°C) in an indicator of selective attention, suggesting that lower temperatures are more favorable for the selective attention required for optimal performance.…”

“…They do show, however, that even when people are close to or at thermal neutrality, lower temperatures lead to better performance. This is consistent, as mentioned earlier, with the relationships developed by Seppänen et al, 6 Lan et al, 7 and Wargocki et al 12 That lower temperatures are conducive to improved performance for tropically acclimatized subjects was shown by Tham 14 for office workers in a call center in Singapore and by Porras‐Salazar et al 55 for pupils in an elementary school in Costa Rica. The mechanism by which lower temperatures are beneficial should be investigated in the future, but the present study suggests that this may be the result of lower stress on the physiological thermal regulation system.…”

Climate change and adolescents in South Africa: The role of youth activism and the health sector in safeguarding adolescents’ health and education

“…[35] A large number of studies have documented the effects of tempera ture on educational performance, which is influenced not only by the temperature on the day of examinations, but by the total cumulative heat exposure over the academic year. [36,37] In a meta-analysis involving 18 studies, the authors calculated that students in classrooms with an indoor temperature of 30°C scored 20% lower on tests than those in…”

“…classes around 20°C. [37] The performance of adolescents appears to be more heat sensitive than the performance of adults in occupational settings. [38] Nevertheless, teachers exposed to high temperatures may also become lethargic and irritable.…”

An Air Terminal Device with a Changing Geometry to Improve Indoor Air Quality for VAV Ventilation Systems

“…Despite these regulations, the problem of high contaminant concentration and the lack of thermal comfort have been proven in both buildings built in the classic standard [20][21][22] and airtight buildings (passive and zero-energy) [23,24]. This problem occurs in households, sports facilities [25,26], schools [27][28][29][30], kindergartens [31], office environments [32] etc., which means it is a concern in the entire building sector. When regarding VAV systems, studies have shown that, when they are not properly regulated, there is a risk of contaminant accumulation [8,13,33,34].…”
