Rezumat/Abstract. This research investigates the optimization of energy efficiency in net-zero commercial office buildings through the synergistic integration of biophilic design principles and Double-Skin Facade (DSF) systems in maritime desert climates. The study emphasizes the role of biophilic design in enhancing occupant well-being and reducing energy consumption by incorporating natural elements such as daylight, greenery, and natural ventilation. These elements are strategically integrated with DSF systems to create high-performance building envelopes that align with net-zero energy goals. A comparative analysis was conducted to evaluate the impact of various DSF configurations including different cavity depths, glazing types, and orientations against the conventional Single-Skin Facade (SSF) system. Dynamic thermal modeling was employed to simulate the complex interactions within the facade cavity, ensuring precise calculations of the energy performance for each DSF configuration. The simulations revealed that integrating biophilic elements with multi-story DSF systems can lead to significant reductions in annual cooling loads, with potential savings of up to 32% compared to SSF systems. The research further identifies the optimal DSF configurations that maximize energy efficiency while supporting biophilic principles, such as the incorporation of natural light and views to the outdoors. The findings highlight the potential of combining biophilic design with advanced DSF technologies to not only achieve net-zero energy targets but also to enhance the overall environmental quality and sustainability of commercial buildings in maritime desert climates. This study contributes to the evolving discourse on sustainable architecture by demonstrating how the integration of nature and technology can drive the performance of next-generation green buildings optimization.
