Optimization of Natural Lighting in Workspaces Through Velux Daylight Visualizer Simulation Case Study: Hepta Design Office

Wandi Guntara, Reza Phalevi Sihombing

Abstract


Natural lighting is a crucial element in workspace design that influences comfort, productivity, and energy efficiency. However, suboptimal lighting can lead to light imbalance, glare, and visual discomfort, thereby affecting user productivity. This study aims to optimize natural lighting in the Hepta Design (Segara Ide) office using Velux Daylight Visualizer simulation. The research process began with field data collection, including room dimensions, the position and size of openings, and furniture layout that affects light distribution. These data were used to create a three-dimensional model of the workspace, which was then analyzed through lighting simulations at various times and weather conditions. The simulation results showed that the average Daylight Factor (DF), luminance, and illuminance exceeded recommended standards, necessitating design adjustments. Modifications such as adding shading elements (sunshades) and altering openings successfully improved natural light distribution while reducing excessive intensity. The optimized design proved to enhance visual comfort, energy efficiency, and workspace quality, serving as a reference for other workspace designs.
