Résumé
In addition to the correspondence to cultural background and social customs, it is commonly acknowledged that traditional buildings embed many climatically responsive features which contribute to the achievement of indoor thermal comfort. Vernacular architecture was always adopting physical principles which were processed within the urban settings and the building as an integrated structure. This research examines the potentials of traditional building methods in hot-arid climate to assess the role of common features incorporated within. A principle passive design strategy is determined and different nominated features are examined through the empirical study within a holistic passive framework. Assessments focused on the impact of different features and building material, as well as the interoperability of those features within the integral passive system. The experimental study employed different thermal simulation tools, i.e. TRNSYS 17 and computational fluid dynamics (CFD). Simulation models were validated against field measurements of indoor temperatures for selected cases. A comparative analysis was applied to adopt a case which showed the validity to be introduced as an integrated model for passive design. The analysis verified the role of thermal mass and shading mechanisms in lowering the indoor temperature. An equation to predict the air change rates was subsequently inferred from the aggregated results obtained through the CFD modelling for the adopted case. The air flow analysis addressed the role of the courtyard and fenestration system in the natural ventilation process. Through thermal simulations and air-flow modelling the empirical work demonstrated the influence of the adopted features on lowering the indoor temperature and improving the indoor air quality. The study confirms the contribution of such methods to the enhancement of the indoor thermal comfort and energy efficiency.
