Heat stress-related illness attributed to the changing climate, particularly the more frequent extreme high temperatures, is becoming a theme of public concern, especially in the most vulnerable regions, such as the African continent. Knowledge of the existing research directions and gaps on heat stress and human health is vital for informing future strategic research foci capable of influencing policy development, planning, adaptation, and mitigation efforts. In this regard, a bibliometric...

We performed a survey of the types of bedroom ventilation in Danish dwellings (January–February 2020) and the associated subjective sleep quality. Five hundred and seventeen people responded. Their median age was 33 years old and 55.4% of them were males. We used an online questionnaire and collected information on the type of bedroom ventilation, bedroom airing behaviour by the respondents, the bedroom environment, building surroundings and location, and sleep disturbance caused by stuffy...

Monitoring the thermal comfort of building occupants is crucial for ensuring sustainable and efficient energy consumption in residential buildings. Existing studies have addressed the monitoring of thermal comfort through questionnaires and activities involving occupants. However, few studies have considered disabled people in the monitoring of thermal comfort, despite the potential for impairments to present thermal requirements that are significantly different from those of an occupant...

This paper studies differences in the effect of temperature on cognitive performance by gender in a large controlled lab experiment (N = 543). We study performance in math, verbal and cognitive reflection tasks and find that the effects of temperature vary significantly across men and women. At higher temperatures, women perform better on a math and verbal task while the reverse effect is observed for men. The increase in female performance in response to higher temperature is significantly...

A group of architects in West Africa are pushing to use mud over concrete to build houses. In countries such as Burkina Faso, as people have become wealthier, they have transitioned to using …

Children spend a significant proportion of their time at school and in school buildings. A healthy learning environment that supports children should be thermally conducive for learning and working. Here, we aimed to study the relations between indoor classroom temperatures and learner absenteeism as a proxy for children’s health and well-being. This one-year prospective study that spanned two calendar years (from June 2017 to May 2018) entailed measurement of indoor classroom temperature...

Although countries in East-Africa seem to have a perfect climate, people are not fully benefiting or making efficient use of its potential. They suffer from insufficient daylight or overheating and live on sites that are not coherently organized nor efficiently utilised. Energy is wasted. Trees are considered an abundant energy provider, especially for cooking purposes or for burning bricks. The Forum on ‘Raising Awareness for Climate Responsive Design in East Africa’ took place in Kampala...

This study managed to create thermal comfort conditions at three temperatures (24°C-T24, 26°C-T26, and 28°C-T28) by adjusting clothing and air velocity. Thirty- six subjects (18 males and 18 females) were exposed to each of the three conditions for 4.5 h in a design balanced for order of presentation of conditions. During each exposure, they rated the physical environment, their comfort, the intensity of acute subclinical health symptoms, and their mental load, and they performed a...

Conducive attributes of physical learning environment of schools play a dominant role in the successful delivery of lessons for slow learners. This study aims to propose a framework towards achieving conducive attributes of preschool learning environment suitable for slow learners through literature review. In summary, the physical conditions including human comfort (visual, thermal, acoustic), spatial planning, quality of furnishing and finishing and safety features are important attributes...

The TAIL rating scheme was developed to assess indoor environmental quality (IEQ) in offices and hotels undergoing deep renovation and was recently extended by the PredicTAIL method allowing prediction of IEQ through modeling. TAIL provides the methodology for rating the quality of the thermal, acoustic, and luminous environments, the indoor air quality, and the overall quality of the indoor environment. The present work is an extension of the use of TAIL rating scheme for school classrooms...

The aim of the study was to examine the effect of the perceptions of students about classroom learning environment on their academic achievement at secondary level in the Mathematics classrooms. The participants were selected from the secondary and higher secondary schools located in Tehsil Rawalpindi and Islamabad (Federal Area), Pakistan. Twenty four schools were selected randomly. A total of five hundred sixteen students of 10th grade studying Mathematics in twenty seven classrooms, were...

Higher ventilation rates were verified to have a positive impact on indoor air quality and therefore benefit sleep quality. However, how does ventilation influence bedroom air quality if the outdoor air quality is poor? Whilst ventilation helps to reduce indoor pollution it inadvertently brings outdoor pollution indoors, such as NO2, which is from vehicular emission. In this study, we collected the info of window and door status during sleep and measured carbon dioxide (CO2), nitrogen...
