Cross-sectional survey. Persons with disabilities are disproportionately impacted by extreme weather disasters and climate change. Individuals with spinal cord injury (SCI) are especially at risk due to inability to control their body temperature and mobility concerns. We surveyed rehabilitation professionals in the field of SCI to determine their experiences, concerns and educational needs regarding natural disasters, climate change and sustainability and the effects on their clientele....

At the core of our growing societies, energy supply stands as one of the major concerns today, and it will be an inevitable challenge for our near future. As the nations are looking to find solutions for the transition from fossil fuels – depleting at a high rate – to alternative energy sources, solar energy through PV cells is getting attention as an affordable and easily implemented option especially for power supply in commercial and residential buildings. This work consists in analyzing...

Acknowledgements Research was conducted to assess the impact of the environmental science component of the PEL Institute on participant's design and successful implementation of MAPs. Three surveys were administered to determine participants' knowledge, attitudes, and commitment to affect change regarding environmental science issues in Pakistanpre-institute, postinstitute, and post-implementation of MAP. (The latter results have not yet been analyzed.) In addition, participants responded to...

Model Predictive Control has gained much attention due to its potential to improve building operations by reducing costs, integrating renewable energy sources, and increasing thermal comfort. This paper aims to compare the accuracy of grey-box models based on resistance–capacitance (RC) networks and Long-Short-Term Memory (LSTM) neural networks in the prediction of the buildings’ thermal response, which is a key feature for the successful implementation of predictive controllers. Indoor air...

This study presents a comparison of classroom learning performance between courses taught in naturally ventilated (NV) rooms and air-conditioned (AC) rooms. This is done to examine effect of thermal comfort standard followed — PMV based or adaptive thermal comfort — on learning. The same group of students, attending different courses in the two classroom types over two years, was chosen to avoid inter-student difference of aptitude and ability. Performance was measured on basis of final...

Occupant behaviour (OB) is one of the main causes of the energy performance gap between buildings’ performance prediction versus reality, since, due to its uncertainty and unpredictability, it is often oversimplified in the building performance simulation (BPS). Hence, previous studies developed OB models, mainly in the residential and office contexts, in order to predict and represent human behaviour in BPS. Yet, school buildings are different from other typologies due to contextual factors...

A novel dynamic model for the temperature inside buildings is presented, aiming to improve energy efficiency by providing predictive information on the heat demand. To analyse the performance and generalizability of the modelling approach, real measurement data was gathered from five different types of buildings. Easily available data from various sources was utilized. The chosen model structure leads to a minimal number of input variables and free parameters. Simulations with real data from...

Building air-conditioning and mechanical ventilation (ACMV) systems are responsible for significant energy consumption and yet, dissatisfaction with the thermal environment is prevalent among the occupants, revealing a widespread disparity between energy-efficiency and indoor thermal-comfort in buildings. This paper presents an indoor-climate control framework that bridges this gap between energy and comfort. The framework comprises two main components: a thermal-comfort prediction model,...

A field lab study was conducted to determine how much the indoor climate parameters, ventilation and lighting, influence children's academic abilities. The study involved 92 children, aged 10–12 years, who over four weeks answered a questionnaire and three different performance tests, which measured their processing speed, concentration, logical reasoning and math solving abilities. An experimental design was constructed to test the effect of changing the lighting from constant warm light...

This study presents thermal comfort and relevant parameters for kindergarten children in naturally ventilated classrooms in Seoul, Korea. The dry-bulb temperature, relative humidity, the airflow velocity, and the globe temperature were measured at 10 randomly selected kindergartens from April to June, 2013, and a survey was conducted three times a day for 119 kindergarten children (age: 4–6) to investigate their thermal comfort, clothing insulation, and metabolism. The effects of these...
