A recent study has shed light on the thermal comfort of preschool children in China’s hot summer and cold winter zone, revealing striking differences in their thermal sensations compared to adults. Conducted by Weiming Chen from the Department of Building Science at Tsinghua University, the research involved a comprehensive survey of 205 children aged 4 to 6 years and 25 teachers, generating an impressive 6,441 records. The findings, published in the journal ‘Indoor Environments’, highlight critical insights that could influence future architectural designs and building regulations aimed at improving indoor environments for young children.
The study uncovered that a significant 52% of the surveyed sessions reported feelings of excessive heat, even though many indoor temperatures fell below established comfort levels. This paradox raises important questions about how we design spaces for children. “Children reported more hot sensations than adults, with almost no cold sensations reported,” Chen noted, emphasizing the need to rethink our assumptions about thermal comfort in educational environments.
One of the primary contributors to the discomfort was identified as over-clothing. The average clothing insulation level for the children was found to be 1.78 clo, which is 0.19 clo higher than that of adults. This discrepancy suggests that many children were dressed excessively, akin to wearing an additional vest and T-shirt. Chen explained, “The excessive clothing likely stems from parental overconcern for cold environments, leading to preventative dressing.” This insight is particularly relevant for architects and builders, who must consider not only the physical space but also the behavioral aspects of its occupants.
Moreover, children exhibited limited initiative to adjust their clothing, which further complicates the issue. Those who wore less clothing reported significantly better thermal comfort. This finding underscores the importance of designing flexible environments that allow for individual comfort adjustments, particularly in kindergartens where children spend a substantial amount of their day.
The implications of this research extend beyond immediate comfort. As the construction sector increasingly focuses on creating sustainable, energy-efficient buildings, understanding the unique needs of preschool children can lead to innovations in design and materials that promote better indoor climates. For instance, integrating adjustable ventilation systems or using materials that enhance thermal regulation could be beneficial in creating spaces that cater to the specific comfort needs of young children.
As the construction industry continues to evolve, insights like those from Chen’s research will be pivotal in shaping future developments. By prioritizing the thermal comfort of vulnerable populations such as preschoolers, architects and builders can contribute to healthier, more conducive learning environments.
