Building Systems Optimization and Strategy Assessment for an Energy-Efficient Model of Buildings: A Case Study of a Residential Building in Benguerir City in Morocco

This paper aims at investigating the effect of building architectural and envelope parameters such as building orientation, window size, infiltration rate, glazing, and construction material on a case study of building’s energy performance in a hot and semi-arid climate. To this end, a multi-objective optimization was conducted using a genetic algorithm (NSGA-II) coupled with the dynamic simulation tool TRNSYS to find the best solution that offers significant energy savings and thermal comfort at a minimum cost. The research specifically targets a residential building located in the green city of Benguerir in Morocco. The results show that by implementing the optimized solution, both heating and cooling demands can be reduced by up to 2 kWh/m2 yr and 10.2 kWh/m2 yr, respectively. The insights gained from this study provide valuable guidance for implementing strategies that prioritize energy savings and contribute to a more sustainable built environment.
