Improving Daylight Utilization and Energy Efficiency in Industrial Workspace Through Window-To-Wall Ratio and Orientation Analysis

Abstract

Window size and orientation have the potential to save energy. Therefore, analyzing and optimizing the window-to-wall ratio (WWR) to enhance building energy efficiency is crucial. This study aims to determine the impact of window orientations and WWRs on energy efficiency by incorporating daylight in an industrial building. This study consists of two experimental settings that were analyzed using DIALux lighting simulation software. Changing WWRs for an east-facing window, and changing WWRs for window orientations from 0 to 360 degrees. It is found that the best WWRs and orientations underscore the fact that thoughtful daylight integration in industries significantly decreases energy use. This allows for a framework for designing energy-efficient industrial buildings that exploit. Together, these experiments show that WWR and window orientation are crucial. This work is aimed at optimizing daylight utilization and minimizing energy usage in industrial workspaces. This study shows that 60% WWR and orienting windows to the southeast or southwest minimize the usage of artificial light, effectively reducing energy costs. Future research should address dynamic lighting control systems to create a condition that provides adequate light in the absence of daylight.
