Investigating the Impact of Different Glazing Types on the Energy Performance in Hot Arid Climate

Abstract

This study investigated the effect of different glazing types with various window orientations and Window to Wall Ratio WWR (10%, and 20%) on energy consumption in a typical room in an office building located in the hot climatic conditions of Aswan, Egypt. This case study was modelled and evaluated using Design Builder software to attain acceptable environmental performance for the study case while also investigating its impact on the amount of energy required for cooling, lighting, and heating. The researc h revealed that using an embedded nanogel layer between two layers of argon and two layers of single transparent glazing with (WWR=10%) resulted in a significant reduction in total annual energy use for all directions (North, West, South, and East), saving 3.66 %, 12.71 %, 6.51 %, and 4.18 % respectively when compared to a single layer of clear glass (3 mm). Furthermore, the results show that utilizing an integrated nanogel layer between two layers of argon and two layers of single transparent glazing has about the same efficiency as WWR=10% when WWR=20%. The study went into further depth to assist decision-makers by using the Pugh matrix to determine the optimum glazing among the proposed glazing types according to several studied criteria. It was discovered that utilizing an integrated nanogel layer between two layers of argon and two layers of single transparent glazing gave the best outcomes, obtaining a score of 3.54, which was higher than any score for the other proposed glazing types.

The Influence of Buildings Proportions and Orientations on Energy Demand for Cooling in Hot Arid Climate

“…Building usage (hours of occupancy) was assumed to be constant according to the traditional Egyptian lifestyle [37]. Internal heat gain from occupancy and appliances, as well as energy demand for heating, and lighting were not considered in the study scope due to their minor contribution to total energy consumption in buildings located in hot arid regions [7,13].…”

“…Building physics, internal conditions, building geometry [4], building envelop, and glazing types are all widely acknowledged to have a considerable influence on improving thermal performance and energy efficiency [5][6][7][8][9][10][11][12][13][14][15][16]. Also, geometric configurations, specifically building proportions, can have an impact on the building's energy performance [17].…”

Energy Efficiency Coupled with Lightweight Bricks: Towards Sustainable Building: A review

“…The lodging industry is responsible for a significant portion of these environmental consequences [22]. In most cases, lodging establishments use methods in their design and services that need a lot of resources like electricity and water, as well as disposable items [26][27][28][29]. Typically, efficient resource usage from the building design to the end-users is low [22].…”

“…Implementing active or passive energy-efficient strategies can improve building energy consumption [16]. Improvements to Heating, Ventilation, and Air Conditioning (HVAC), electrical lighting, and other such systems are examples of active methods, while alterations to the components of the building envelope are examples of passive techniques [26,28,31,36,37]. As a result of developments over the last few years, there has been a resurgence of interest in energy efficiency initiatives that are friendly to the environment and are meant to alleviate worries over environmental pollution and the energy problem [16].…”

An Assessment of External Wall Retrofitting Strategies Using GRC Materials in Hot Desert Regions

“…Because of the increased thickness, existing buildings will have less available internal space and will have higher insulation costs. In that context, optimizing the building envelope materials to reduce the interior temperature to keep the thermal comfort inside the building within the acceptable range remains a key concern associated with reducing the energy required for cooling [31]. This is due to the conductivity of building materials which has a significant impact on heat transfer, particularly through external walls.…”
