The use of double skin façade to optimize thermal comfort – Case of public buildings in Constantine –

Abstract

The idea of sustainable development has been presented as the rescuer of a dying planet since the Rio Summit in 1992. It is an attempt to balance environmental concerns with development at the nexus of the social, ecological, and economic domains. Energy use is also connected to the CO₂ emissions that hasten climate change. The largest emitter of greenhouse gases is the building industry, which also consumes the most energy. Environmental problems have become economic problems as a result of political leaders' growing understanding of the effects of climate change. One of the most important components of a building's energy efficiency is its facade. It improves passenger comfort and tempers the climate. Its functions include lowering energy expenses, fostering a safe and healthy atmosphere, and enhancing the building's aesthetic appeal. The construction industry has the most potential in the current climate of lowering energy consumption and greenhouse gas emissions; one strategy under consideration is the creation of double facades, also known as double-skin facades. A double-skin facade is a popular building method among architects, builders, and end users, owing to its excellent quality, aesthetic possibilities, and proven thermal and acoustic insulation benefits.It is possibly the most effective solution for building insulation since it avoids thermal bridging, condensation, and noise problems. These facades provide control over light penetration, sound, and warmth in rooms induced by solar radiation. When properly constructed, "double-skin facades" can greatly improve occupant comfort. Our study mostly concentrates on the effectiveness of double-skin facades and how well they optimize thermal comfort. The goal is to illustrate how they might increasethe difference in temperature between the inside of the building and the outside. It also aims to show how double-skin facades may improve a building's thermal comfort. In order to show how successful "double-skin facades" are in terms of thermal comfort; this study will look at the instance of public buildings in Constantine that have double-skin facades but were built with diverse methods and materials.
