Improvement of thermo-aeraulic comfort with integrated solar wall system under Saharan climate

Abstract

Abstract. The aim of this paper is devoted to an example of a concrete application in the bioclimatic architecture: integration of a simple solar air collector in building facades under Saharan climate. The originality of this work is to lift a serious problem that is often encountered in the summer when the indoor air cooling mode through natural ventilation becomes ineffective. We showed that the specific architectural integration of solar air collectors can bring a positive support to the thermo-aeraulic comfort by controlling the mass flow rate of the air entering to the heated building zone in cold season. The major inconvenience of this technique is often encountered in summer. To ensure the reliability of this technique that is sometimes regrettable, it is first necessary to control automatically the opening and closing the air ventilation valve.

The impact of efficient insulation on thermal performance of building elements in hot arid region

“…In the hot Saharan climate, thermal storage in building elements can play a negative role on the desired comfort conditions. This issue can be eliminated by enhancing the thermal insulation of facades by inserting reflective films as well as serving appropriate ventilation systems, as proposed by Bekkouche et al [11]. Aboulnaga and Moustafa [12] aimed to modify an existing multi-floor building in Egypt, by suitable insulation materials, using simulation tools.…”
