With the growing demand for housing and the associated increase in emissions and energy consumption, research has intensified in recent years to address these challenges. Morocco is known for its climate diversity, with each location being associated with distinctive energy demands and sustainability challenges. This study sheds light on the thermal and energy performance of a modular residential house in the hot and semi-arid climate of Benguerir city in Morocco, with an aim of providing insights applicable to similar regions. Several active and passive design techniques combinations are investigated using EnergyPlus dynamic thermal simulation. The effects of different thermal insulation options, adding cool roof technology, switching building orientations, and enabling natural ventilation are assessed. Insulation notably lowers annual energy use, reducing both cooling and heating demands by 29.8% and 40.3%, respectively. Adding cool roof technology while identifying optimal orientations further cuts cooling needs by about 500 kWh/year. Furthermore, enabling natural ventilation also contributed to energy savings, lowering total cooling energy requirements by about 545 kWh/year. The study hence showcases how combining these measures significantly improves overall performance, supporting the viability of well-designed sustainable modular housing in hot and semi-arid climates.

摘要

With the growing demand for housing and the associated increase in emissions and energy consumption, research has intensified in recent years to address these challenges. Morocco is known for its climate diversity, with each location being associated with distinctive energy demands and sustainability challenges. This study sheds light on the thermal and energy performance of a modular residential house in the hot and semi-arid climate of Benguerir city in Morocco, with an aim of providing insights applicable to similar regions. Several active and passive design techniques combinations are investigated using EnergyPlus dynamic thermal simulation. The effects of different thermal insulation options, adding cool roof technology, switching building orientations, and enabling natural ventilation are assessed. Insulation notably lowers annual energy use, reducing both cooling and heating demands by 29.8% and 40.3%, respectively. Adding cool roof technology while identifying optimal orientations further cuts cooling needs by about 500 kWh/year. Furthermore, enabling natural ventilation also contributed to energy savings, lowering total cooling energy requirements by about 545 kWh/year. The study hence showcases how combining these measures significantly improves overall performance, supporting the viability of well-designed sustainable modular housing in hot and semi-arid climates.
