Energy Efficiency Evaluation of Different Glazing and Shading Systems in a School Building

Abstract

The energy conversations methods and techniques take a significant role in the energy performance of the buildings. Façade and shading systems are in continuous development, and recent studies are showing the importance of implementation of such systems to reduce energy consumption and enhance the effectiveness of the building performance. School buildings are mostly being used during daytime, hence, require active use of sunlight. A measure that is taken on a school building envelope can prevent overheating and overcooling and reduce the heating and cooling energy consumption but at the same time can increase the lighting energy consumption vice versa. Thus, it is necessary to optimise the energy required for climatisation of a building with lighting energy demand. The main aim of the paper is to provide analysis for façade and shading systems applied to a school building and study the effectiveness of it on energy consumption and conservation. The case study for this paper is a typical building project designed to be located in Istanbul, Turkey and has a traditional façade system which is clear double layer windows without any shading devices. The analyses of the energy efficiency of these systems will be presented. The different glazing types and shading systems alternatives will show the most efficient one to be used as some optimised alternatives for the systems. Findings indicate that proper glazing and shading systems can reduce the needed energy for heating and lightening and thus total energy consumption of a school building significantly.

An overview of motivators and challenges of passive design strategies

“…Also, adoption of PDS could protect biodiversity and ecosystems. This is supported by studies in India, China, and Malaysia stating that the environmental benefits are driving the adoption of PDS, resulting in an increase in the PDS adoption rate [50,55]. Clearly, these factors make a positive contribution to the adoption of PDS [56].…”

“…Due to clients' uncertain knowledge and awareness of PDS, consultant service providers play the key role in explaining, suggesting, and persuading them to adopt PDS [46]. Furthermore, consultants' professional accreditation and knowledge of PDS allow them to maintain their reputation and create a superior image, which further motivates the client to adopt PDS [55]. This is supported by studies in Malaysia, Hong Kong, and Australia stating that consultant influence drives their adoption of PDS [53,61].…”

Effect of photovoltaic installation power and façade glazing ratio on the energy performance of a nursery building

“…A particular type of research in this area focuses on solutions in the field of façade glazing, as it is often considered an element linked to the system of mutual interactions with structural elements of the building and its equipment (Alekhin et al, 2018;Seyedehzahra et al, 2016). Due to the complexity of the issues, research is often narrowed down to representative functional groups of buildings, including public buildings, (Khalaf et al, 2019;Romagnoni et al, 2006;Wang and Wei, 2021) and climatic zones, (Lam et al, 2008).…”

Review on Energy and Fire Performance of Water Wall Systems as a Green Building Façade

“…Having a system to prevent heat transmittance through the façade lowers the building energy demand [17], which results in less carbon emissions [18,19]. Therefore, careful consideration is needed in designing the glass façades to get the delicate balance of energy over the building envelope together with adequate daylight to reduce the artificial lighting [2,[20][21][22].…”
