Optimizing Energy Efficiency: Louver Systems for Sustainable Building Design

Abstract

As the global focus on sustainability intensifies, architects and engineers are increasingly seeking innovative passive strategies to improve building energy efficiency. Among these strategies, the strategic integration of louvers has garnered significant attention due to their potential to optimize building envelope performance and reduce energy consumption. Louvers effectively manage solar heat gain, mitigating the impact of extreme temperatures on indoor spaces. Consequently, louvers reduce the reliance on active HVAC systems, leading to notable energy savings and a decreased carbon footprint. This paper presents a comprehensive review of the role of louvers in enhancing building energy efficiency, highlighting their designs, efficiency, and improvement suggestions. Moreover, this review article addresses potential challenges related to louver design, such as balancing the trade-off between solar heat gain and daylighting and how to optimize louver configurations for specific building types. Approaches to overcome these challenges, including advanced modeling techniques and parametric design, are also explored to assist architects and designers in achieving the most energy-efficient outcomes.
