Enhancing Energy Consumption in Egypt Within Adaptive Facade Techniques

Abstract

Building facades play a pivotal role in influencing energy efficiency and indoor comfort. In the pursuit of sustainable building practices, this research investigates the implementation of adaptive facade technologies in office buildings within the hot-dry climate of Cairo, Egypt. The study aims to assess the efficiency of adaptive facade techniques, such as thermochromic, photochromic, gasochromic, and electrochromic glazing, in mitigating energy consumption. Through simulations of various glazing types, the research yielded a substantial reduction in energy consumption, ranging from 20% to 28%. This reduction was accompanied by a noteworthy decrease in carbon emissions. These findings underscore the potential of adaptive facades to enhance building performance and sustainability within hot-dry climates. The study contributes valuable insights for architects seeking eco-friendly solutions in energy-efficient building design. By harnessing the power of adaptive facades, we can reduce energy consumption and environmental impact while providing a more comfortable and sustainable built environment, especially in regions with challenging climates like Cairo, Egypt.

Smart Glazing Systems vs Conventional Glazing: A Comprehensive Study on Temperature Control, Daylighting, and Sustainability

“…However, when voltage is applied, the liquid crystals reorient, allowing light to pass through [37]. According to the study, switchable glazing solutions can result in significant energy savings of between 20% and 28% [38]. This dynamic response to voltage changes results in varying levels of transparency for LC glazing, with light transmittance typically around 50% in the opaque state and less than 70% in the active state [39].…”
