“…Overall, the reports indicate that a majority are dissatisfied with thermal quality. This thermal unsatisfaction has been reported by other studies in tropical climates, resulting in proposed models to increase thermal quality [59], of which Fanger's PMV model is one of the tools to predict thermal satisfaction to improve quality of the variables.…”

“…Standards, such as the ASHRAE Standard 55 [15], provide guidelines to predict thermal comfort with the use of modes such as Fanger's PMV-PPD model. Comparisons of Fanger's PMV-PPD with thermal sensation mean vote have been performed in various studies [59][60][61]. This comparison is usually performed to localize and upgrade accuracy in Fanger's PMV-PPD predictions.…”

A Field Study on Thermal Comfort and Cooling Load Demand Optimization in a Tropical Climate

et al. 2021

Energy consumption to cool an indoor environment is a substantial part of total energy end-use, particularly in a tropical climate with high energy demand for cooling. To improve energy efficiency, cooling systems can be optimized using a variety of neutral indoor temperatures to maintain a balance between an occupant’s thermal comfort and cooling energy demand. This explanatory study investigated the thermal quality and cooling energy demand of a Platinum-certified office building in the tropical climate of Malaysia. The investigation aimed to suggest a balance between occupant thermal comfort and cooling energy demand. The thermal investigation includes an objective field measurement that implements environmental equipment to monitor thermal quality and a subjective occupant’s thermal feedback using a questionnaire survey. To calculate cooling energy demand, the total equivalent temperature difference method (TETD) is applied. The results suggested an occupant’s cooling sensation of around 24 °C, with no significant difference concerning age and gender. Cooling load calculation indicated a 36% energy reduction by increasing air temperature to 26 °C, for occupants to feel thermally comfortable in a tropical climate. These findings contribute to improving sustainable energy policies, sustainable construction, and thermal comfort improvement for a tropical climate.

“…The mean air relative humidity obtained for 35 minutes, that the trailer in the study, was tested is similar to that obtained by Aldridge et al (2019) for 15 to 45 minutes. The hot period of the humid tropical climate is generally characterised by high air temperature and high relative humidity of about 30°C and 80% respectively (Kiki et al, 2020), which could be detrimental to animals' welfare and health. Therefore, for poultry birds, raised in the humid tropical climate, subjecting them to an average air relative humidity of less than 70%, as reported in this study, might help to alleviate the negative effect of the high temperature (above 30°C) on the welfare and health of poultry birds during transportation.…”

The demand for poultry products has made it necessary for farmers to transport poultry birds from farmhouses to where they could be processed for the consumers. However, transporting poultry birds over a long distance, and under unfavourable conditions, could cause a shift in their behaviours, and biochemical reactions, resulting in an increase in birds’ traumatic injuries, weight loss, and poor meat quality. Therefore, a motorbike powered trailer was developed, having an average loading capacity of 50 to 54 broiler chickens, with a live body weight of 1.5 kg, for small-scale farmers. The climatic conditions (temperature and relative humidity) within the trailer were evaluated when the trailer was tested on the motion for 35 minutes during the hot period of the day (1:30 pm to 2:05 pm). The result showed that the indoor temperatures ranged between 29.3°C and 31.6°C and the outdoor temperatures ranged from 31.0°C and 33.3°C. Similarly, the indoor relative humidity was between 61 and 69% while that of outdoor relative humidity was between 56% and 64%. The mean apparent equivalent temperature (AET) of the trailer was estimated as 30.45 ± 0.54°C. This implies that the thermal zone within the trailer could be considered safe for poultry birds during hot weather periods in the humid tropical climate. The total production cost of the trailer was two hundred and forty-three US dollars, eighty cents ($243.80).

“…The primary health outcomes of the studies cited in this review are health risks associated with increased temperatures and heat stress (Joseph and Demot, 2021; Morakinyo et al 2016 ; Van de Walle et al 2022 ; Gratien Kiki et al 2020 ; Mabuya and Scholes 2020 ; Sylla et al 2018 ; Wright et al 2022 ). For instance, Mushore et al (2017) identified outdoor thermal discomfort in densely built-up areas, and Ndetto and Matzarakis (2013), Ndetto and Matzarakis ( 2017 ) and Sarr et al ( 2019 ) found heat stress and thermal discomfort to be the major health issues during the hot season leading to heat exhaustion, heatstroke, and overall discomfort affecting daily activities.…”

This review examines high-quality research evidence that synthesises the effects of extreme heat on human health in tropical Africa. Web of Science (WoS) was used to identify research articles on the effects extreme heat, humidity, Wet-bulb Globe Temperature (WBGT), apparent temperature, wind, Heat Index, Humidex, Universal Thermal Climate Index (UTCI), heatwave, high temperature and hot climate on human health, human comfort, heat stress, heat rashes, and heat-related morbidity and mortality. A total of 5, 735 articles were initially identified, which were reduced to 100 based on a set of inclusion and exclusion criteria. The review discovered that temperatures up to 60°C have been recorded in the region and that extreme heat has many adverse effects on human health, such as worsening mental health in low-income adults, increasing the likelihood of miscarriage, and adverse effects on well-being and safety, psychological behaviour, efficiency, and social comfort of outdoor workers who spend long hours performing manual labour. Extreme heat raises the risk of death from heat-related disease, necessitating preventative measures such as adaptation methods to mitigate the adverse effects on vulnerable populations during hot weather. This study highlights the social inequalities in heat exposure and adverse health outcomes.
