Thermal comfort varies significantly between individuals and regions depending on factors such as activity level, clothing, space temperature and relative humidity. This study considers the estimation of thermal comfort parameters such as air temperature, mean radiant temperature, air velocity, emissivity of space, metabolic rates, and heat transfer coefficients to determine comfort index, predicted mean vote, and predicted percent of dissatisfied people. Several equipment were employed to...

Noise is increasingly becoming a problem in schools and affects the audibility of speech. The effects of noise hamper learning opportunities for students. Noisy classrooms affect students’ academic performance and wellbeing. Studies have shown that children perform more poorly in noisy situations compared to adults. The current study was done to measure noise levels in classrooms in primary schools in Kuantan. A total of 31 classrooms from eight residential primary schools were selected as...

The data from published studies were used to derive systematic relationships between learning outcomes and air quality in classrooms. Psychological tests measuring cognitive abilities and skills, school tasks including mathematical and language-based tasks, rating schemes, and tests used to assess progress in learning including end-of-year grades and exam scores were used to quantify learning outcomes. Short-term sick leave was also included because it may influence progress in learning....

A field lab study was conducted to determine how much the indoor climate parameters, ventilation and lighting, influence children's academic abilities. The study involved 92 children, aged 10–12 years, who over four weeks answered a questionnaire and three different performance tests, which measured their processing speed, concentration, logical reasoning and math solving abilities. An experimental design was constructed to test the effect of changing the lighting from constant warm light...

Objectives: The objective of this study was to identify and appraise evidence on the direct and indirect impacts of high indoor temperatures on health; the indoor temperature threshold at which the identified health impacts are observed; and to summarise the evidence for establishing a maximum indoor temperature threshold for health. Study design: This is a systematic literature review and narrative synthesis. Methods: A review of the published literature using MEDLINE, EMBASE, Global...

Summary of the research on how thermal, air quality, noise reduction, lighting, and daylighting improvements in classrooms benefit children’s educational attainments
-
This report summarises published research on how children’s performance of schoolwork in primary and secondary schools and their subsequent educational attainments are affected by classroom temperature, air quality, noise, and lighting. The main conclusions (Items 1-20) are set out below as unequivocal statements that are validated by the findings of the detailed reviews of research published that form the bulk of the report, or by the findings of research published since those reviews were...
