Évaluation expérimentale et par simulation des performances thermiques de techniques passives appliquées aux toitures pour le rafraîchissement des bâtiments en climat chaud

Abstract : The building is one of the most energy-consuming and CO2-producing sectors in the world. Nowadays, this sector accounts for 33% of total energy consumption in Morocco. The new thermal regulation in Morocco aims to introduce eco-energy practices in this sector to reduce this consumption. Indeed, in the Mediterranean region, building architecture has a major impact on its energy and thermal performance. In addition, the integration of passive techniques and the use of local materials could significantly reduce energy consumption in the building sector. In this context where this thesis is located and whose objective is to evaluate the cooling capacity of some passive techniques for the solar protection of roofs and to show the importance of the use of local natural materials in the hot and semi-arid climate of Marrakech. Indeed, three passive cooling techniques are tested in real conditions in the Marrakech region. Passive techniques, namely white paint, shading and thermal insulation, are applied to the roofs of three outside test cells. The thermal performances of these techniques are evaluated simultaneously via a 29-day summer monitoring of four identical test cells, including a bare roof reference test cell (without treatment). Small scale test cells do not represent real buildings where an in-depth study can be conducted. To remedy this, we built a single-zone building that represents a classroom in rural region in southern Morocco, using natural materials and incorporating passive techniques into the roof. The thermal and energetic performances of the same techniques are evaluated by means of dynamic thermal simulations on TRNSYS as well as an experimental study.
