“…In addition, temperature and high humidity may also indirectly affect asthma triggers, such as viral infections, bacterial activity, the growth of indoor allergens and time spent outdoors. 9 Most identified studies supported positive associations between high extreme temperature and relative humidity exposures and children's respiratory symptoms, underlying mental and behavioural disorders, diseases of the nervous and circulatory system, especially asthma/wheeze, wheeze/ chest tightness, neoplasms and renal diseases, [10][11][12] where boys were more at risk than girls. Increased years of life lost due to cardiovascular and cerebrovascular diseases are associated with both cold and hot temperatures 13 and the curve was shown to have a sharper rise due to extremes of heat than when exposed to cold.…”

“…They claimed that the statistical significance between them shows strong correlations. Sun et al [13] discovered that bad thermal comfort has significantly co-occurred with children's respiratory diseases (e.g., asthma, dry cough, and pneumonia). Tsang et al [14] and Cao et al [15] discussed that sleep quality is a factor of life quality, and poor thermal comfort directly affects it.…”

Controlling thermal comfort in the indoor environment demands research because it is fundamental to indicating occupants’ health, wellbeing, and performance in working productivity. A suitable thermal comfort must monitor and balance complex factors from heating, ventilation, air-conditioning systems (HVAC Systems) and outdoor and indoor environments based on advanced technology. It needs engineers and technicians to observe relevant factors on a physical site and to detect problems using their experience to fix them early and prevent them from worsening. However, it is a labor-intensive and time-consuming task, while experts are short on diagnosing and producing proactive plans and actions. This research addresses the limitations by proposing a new Internet of Things (IoT)-driven fault detection system for indoor thermal comfort. We focus on the well-known problem caused by an HVAC system that cannot transfer heat from the indoor to outdoor and needs engineers to diagnose such concerns. The IoT device is developed to observe perceptual information from the physical site as a system input. The prior knowledge from existing research and experts is encoded to help systems detect problems in the manner of human-like intelligence. Three standard categories of machine learning (ML) based on geometry, probability, and logical expression are applied to the system for learning HVAC system problems. The results report that the MLs could improve overall performance based on prior knowledge around 10% compared to perceptual information. Well-designed IoT devices with prior knowledge reduced false positives and false negatives in the predictive process that aids the system to reach satisfactory performance.

“…1 In environments with poor air quality, people are more susceptible to diseases, especially children and vulnerable groups. At the same time, rising outdoor temperatures can lead to higher indoor temperatures, which can affect people's comfort and health, 2 with a significant impact on respiratory diseases (RDs) in particular.…”

Ambient air temperature could be the most significant factor impacting childhood respiratory health. This paper aims to analyze the relationship between air temperature and childhood respiratory diseases (RDs). Field measurements and meteorological parameters recorded from the weather website were conducted. Health outcomes regarding respiratory diseases amongst preschool children were reported. Multiple logistic regression analyses were conducted. Results from logistic regression analyses illustrate that extreme air temperature was significantly associated with a high prevalence of RDs amongst children. Indoor high temperature (>28°C) was positively correlated with the long duration of a common cold (≥2 weeks), and outdoor high temperature (>35°C) was positively related to the high prevalence of pneumonia. Indoor and outdoor low temperature (<18°C and <4°C, respectively) was a risk factor for rhinitis amongst children. The largest indoor air temperature difference (IATD) (the 4th quartile, >4°C) and outdoor air temperature difference (OATD) (the 4th quartile, >8°C) were positively related to the high prevalence of pneumonia and diagnosed asthma amongst children. Large differences between indoor and outdoor air temperatures and large indoor air temperature variations should be avoided to reduce the adverse effects on respiratory health, especially in extreme climates.
