Evaluating zero-energy strategies in mixed-use buildings: a case study

The building sector is responsible for over 40% of global energy consumption, necessitating innovative strategies to minimize energy usage in both commercial and residential buildings, ultimately striving for zero-energy status. This study addresses the relatively overlooked area of zero-energy buildings within the context of a combined commercial-residential structure, utilizing Carrier (HAP) software for precise thermal and cooling load calculations. The research introduces a multifaceted approach, examining various scenarios that influence energy demand reduction, including wall color modifications, the application of noble gases for window insulation, shading effects, and technical innovations in window dimensions. Notably, this study emphasizes insulation as a cost-effective strategy for achieving zero-energy objectives, revealing that the optimal scenario incorporating krypton insulation, color adjustments, and effective shading achieves a significant 21.36% reduction in energy consumption. This research not only contributes novel insights into mixed-use building design but also provides a practical framework for future energy-efficient building projects.
