Addressing indoor air quality (IAQ) and thermal comfort issues in school buildings is challenging but relevant. Firstly, their primary occupants are more vulnerable than adults. Secondly, often inadequate being too old or designed to prioritise energy-efficiency targets. Thirdly, have little control over the environmental (IEQ). Lastly, SARS-CoV-2 pandemic highlighted complexity vulnerability of existing decision-making processes relation making timely well-informed decisions about IEQ threats. Standards guidelines vary time among similar countries despite targeting occupants, evaluate IAQ independently, do not include any specific adaptations children. Thus, aim this research compare different available standards buildings. By analysing with (EN16798, BB101, ASHRAE 55 62.1) data collected schools northern Italy, evaluated consequences limits approaches, proposed improvements. The conclusions that (i) thresholds methods inconsistency within same standard should be avoided; (ii) upper- lower-bounded operative temperature scales most appropriate means design verify classrooms; (iii) metrics give an upper limit per a certain amount consecutive might prevent build-up pollutants, even high emissions from building fabric; (iv) no proposes combined analysis which could enable informed trade-off considering IAQ, comfort, energy

In educational buildings, adaptive strategies can be adopted for the achievement of thermal comfort and reduction energy consumption. Since climate largely affect comfort, there is a need understanding its role in definition different capacities, neutrality, preference. To this end, 17 naturally ventilated university classrooms from 10 buildings located two sub-climates Italy (Mediterranean climate) France (Continental were analysed. total, 1377 questionnaires associated with environmental parameters collected. The same stage (i.e. classrooms) operation mode during heating period) investigated to remove possible biases related their influence on perception. Field studies show that despite French students performing less actions, neutral temperature (TN) was 3.1 °C lower than Italian ones (TN,ITALY = 23.6 TN,FRANCE 20.5 °C) difference statistically significant. Adaptation as function sub-climate evident comparison PMV-PPD model. Neutral temperatures calculated PMV higher those obtained TSV, increased colder climate. Practically, students' adaptation environments deployed ensure while reducing demand.

School classrooms are often reported as having insufficient ventilation with elevated indoor CO2 concentrations. This paper reports on pre-pandemic field measurements of concentration levels conducted for an academic year in 10 from four primary and a secondary school Victoria, Australia. Measured concentrations across the which were operated mix intermittent natural air-conditioning cooling or heating, average ranged between 657 ppm 2235 during hours median over 1000 70% classrooms. All study exceeded Australian recommended limit 850 ppm. Using peak year-long measurements, estimated rate (VR) 4.08 Ls-1 per person show under-performing where 60% had VRs 35–40% lower than 10-12 Ls−1 recommendation. Estimated VR range 1.24–2.07 using maximum 19–30% ASHRAE recommendation 6.7 person.
