Personal thermal comfort models are crucial for the future of human-in-the-loop HVAC control in energy-efficient buildings. Individual comfort models, compared to average population responses, can provide the personalization required for successful control. In this work, we frame the thermal preference prediction task as a multivariate, multi-class classification problem and use deep learning and time-series-based approach for thermal preference prediction. We combine l1 regularization with...

Abstract The assessment of Nigerian teachers' climate science literacy and training needs on climate change concepts (i.e., causes, impacts, and solutions) are absent. This study relates teachers' climate science literacy and their expressed training needs in other climate change concepts and places teachers in groups. Following a descriptive survey design, 410 teachers were randomly sampled from 8338 public secondary school teachers in Enugu State, southeastern Nigeria. A...

With parents, teachers, and policymakers, reducing class size is a favoured education policy approach. Cursory studies had suggested that overcrowded classroom results in relatively modest in students’ academic achievement. Underpinned by the Social Cognitive Theory, this study assessed how overcrowded classrooms affect the teaching and learning process in Ilemela Municipality, Mwanza -Tanzania. The study adopted a mixed research approach and convergent parallel research design. The sample...

Climate change poses a major threat to the future of today's youth. Globally, young people are at the forefront of climate change activism. Their ability to engage, however, depends on the level of knowledge of climate change and concern about the topic. We sought to examine levels of knowledge and concerns about climate change among youth in South Africa, and their experiences of heat exposure. Ten questions on climate change knowledge, concerns and experiences were nested within a...

This study investigated children’s perceptions and adaptive behaviors related to indoor thermal conditions of classrooms in primary schools with no air-conditioning systems during both summer and winter in Dehradun City, Uttarakhand, India. Responses were collected from 5297 school children aged 6–13 years. During the measurement periods, 100% and 94% of the samples were obtained under conditions outside an 80% thermally acceptable comfort range in winter and summer, respectively. The...

Rising temperatures are causing distress across the world, and for those most vulnerable, it is a silent killer. Information about indoor air temperature in residential dwellings is of interest for a range of reasons, such as health, thermal comfort and coping practices. However, there have been only few studies that measure indoor heat exposure, and contrast these to outdoor temperatures in rural-urban areas, of which none are in South Asia. We aim to close this knowledge gap with our...

This study examines school and college teachers' perceptions about climate change, taking into account academic backgrounds and experiences with the impacts of climate change. The study included 95 teachers from three schools and colleges (two private and one public) in the city of Sylhet, Bangladesh. The results show that most teachers have heard about climate change and understand what it means. Most also perceive that temperatures in Bangladesh are rising or fluctuating and that rainfall...

Climate change is a rapidly progressing threat to global health and well-being. For general practitioners (GPs) currently in training, the effects of climate change on public health will shape their future professional practice We aimed to establish the prevalence and associations of Australian GP registrars' (trainees') perceptions of climate change as it relates to public health, education, and workplaces.A cross-sectional questionnaire-based study of GP registrars of three Australian...

There is good evidence supporting the airborne transmission of many respiratory viruses (measles, influenza A, human rhinovirus and the novel SARS-CoV-2). Relative humidity (RH) is an important factor in understanding airborne transmission as it may impact both airborne survival, inactivation by biological decay, and the gravitational settling of the virusladen droplets. This study aimed to estimate and compare the impact of indoor relative humidity on the airborne infection risk caused by...

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...

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...

Background It is believed that poor classroom acoustics leads to lower levels of student learning and exposes teachers vocal folds to greater physical wear and tear. Objective This study sought to compare the quality of life by World Health Organization (whoqol-bref) questionnaire of 61 teachers working at schools with different acoustic conditions. Methods This paper reports on a descriptive exploratory study aimed at ascertaining the following: (1) outdoor sound pressure levels in the...

Building Energy prediction has emerged as an active research area due to its potential in improving energy efficiency in building energy management systems. Essentially, building energy prediction belongs to the time series forecasting or regression problem, and data-driven methods have drawn more attention recently due to their powerful ability to model complex relationships without expert knowledge. Among those methods, artificial neural networks (ANNs) have proven to be one of the most...

With the rapid urbanization in China, energy consumption and corresponding carbon emissions in residential buildings are growing. Because occupant behaviour plays a significant role in building energy performance and occupant comfort, understanding the crucial links between occupant lifestyles and energy use is the key. Most studies on the relationship between occupancy behaviour and energy usage have been conducted in public or commercial buildings. Because data is difficult to obtain and...

The importance of the agricultural sector to the Nigerian economy is highly invaluable, although, it is highly responsive and vulnerable to climate change. Climate change has caused decline and volatility in agricultural production, thereby exacerbating food insecurity and hunger in countries such as Nigeria. Most of the Nigerian farmers are rainfed and conservative towards technological change, this calls for the need to develop curriculum contents on smart agriculture for youth who will...
