Abstract

This paper investigates the impact of shading and glazing types on the performance of Trombe walls in reducing the carbon footprint of Moroccan residential buildings. Trombe walls, as passive solar heating systems, offer significant potential for energy savings and carbon emissions reduction in residential constructions. Our study evaluates various shading devices and glazing materials to determine their effectiveness in optimizing thermal performance and minimizing energy consumption. Through simulation, we analyze the influence of different configurations on indoor temperature regulation and overall energy efficiency. The findings highlight that Triple Clear (TG 3-13) glazing achieves a substantial 22.5% annual decrease in CO₂ emissions compared to buildings without Trombe walls, while local shading for this glazing type increases emissions by 4.5%. Additionally, dynamic window shading controlled by a predefined schedule reduces emissions by 2% annually compared to static glazing setups. These results underscore the critical role of glazing selection and shading strategies in enhancing sustainability and reducing carbon footprints in Moroccan residential buildings. This research contributes to the development of energy-efficient building practices, supporting Morocco’s commitment to reducing its carbon footprint and promoting environmental sustainability.
