The world is steadily embracing the concept of sustainability, with a growing focus on incorporating sustainable design principles into building construction—particularly in hotels. This approach aims to improve energy performance and minimize construction and operational expenses by utilizing locally sourced environmental materials. Such practices are especially prominent in urban areas characterized by a unique identity and distinctive style, like the Siwa Oasis. The main objective of this article was to examine the impact of utilizing local materials in buildings within Siwa Oasis on enhancing their energy efficiency. This was achieved through an analytical exploration of structures in the region, complemented by an applied study employing DESIGN BUILDER V 7.0 for buildings in Siwa Oasis. The results indicate an improvement in energy performance in hotel buildings in Siwa Oasis by using local materials by a percentage of approximately more than 14% compared to the base case.
