Numerical simulations and analytical models have been used to investigate the possible impact of various dielectric components of vehicles on internal electromagnetic field distributions. It is found that, apart from the window glazing, the dielectrics investigated have little impact on the internal field populations and average field levels, although there are localized field differences that ...

A questionnaire which included items on wheeze, cough, eczema, hay fever, and indoor environment, including parental smoking habits, pet ownership, heating and cooking methods, home insulation, damp, mould, and years lived in their houses, was given to 1801 children, aged 12 and 14 from the Highland Region in Scotland. Of the 1537 (85%) who replied, 267 (17%) reported current wheeze, 135 (9%) c...

The utilisation preference of glazed facades in the hot regions is accompanied by serious environmental and economic impacts. Attempts are continuing to fulfil an optimum balance between minimising heat gains and maximising daylighting benefits; in an economical approach. This study was conducted in Egypt, where a real case study was investigated to evaluate the thermo-visual performance of a b...

The dual-airflow window could be used to conserve energy and improve indoor air quality in buildings because it works like a heat exchanger and can introduce outdoor air into buildings. In order to optimize the window design, this investigation used the orthogonal method to evaluate the importance of these 13 design parameters of the dual airflow window in energy conservation: outdoor air suppl...

The building envelope includes all materials (glazing, external walls, doors, etc.) that separate the conditioned space from outside environment. Building characteristics significantly influence energy consumption of buildings. In this study, research was carried out to find optimum design parameters, such as insulation thickness, orientation, glazing type, and window-to-wall ratio a room, usin...

This paper presents an innovative Concentrating Glazing system to be adopted in smart building façades: The Photovoltaic (CoPVG). device consists of a double-glazing panel integrating series concentrating lenses. A thin layer PV cells is then placed at the lenses' focus. peculiar lens design can produce, by using Total Internal Reflection (TIR), seasonal effect with more light entering low inci...

Abstract Glazing is a critical buildings element as it the most vulnerable envelope part to heat gain and loss accounting for around 50% of building’s energy consumption. However, conventional glazing technologies have relatively low-performance characteristics which cause significant losses during winter undesired in summer. In this regard, study investigates thermal visual performance various...
