Abstract

This study investigates the thermal behavior of a building in Zone 4 (Ifrane) using TRNSYS, focusing on the impact of envelope parameters on energy consumption. Different insulating materials (wood wool, glass wool, expanded polystyrene, and wood fiber) and insulation thicknesses were evaluated to reduce heat losses and enhance thermal comfort. Simulations show that both the type of material and its thickness significantly affect thermal performance, with low thermal conductivity and adequate thickness improving indoor temperature stability and reducing energy use. Results indicate that optimal insulation can increase indoor temperatures by up to 6 °C, substantially lowering heating demand. Expanded polystyrene (EPS) was selected for its favorable cost-performance ratio. The study emphasizes the importance of a comprehensive energy management strategy, integrating building orientation, window performance, and HVAC efficiency, to minimize energy consumption while ensuring optimal occupant comfort.
