Impact of Innovative Lighting Strategies on the Performance of Workplace Environment

Abstract

AbstractInnovative lighting layouts ILS is crucial in the office environment, with a significant impact on occupants’ well-being, visual quality, and saving energy consumption. A technical understanding of light sources and performance is vital in lighting design. Open office lighting settings varies from small areas based on light quantity, fixed approach (recessed/suspended), and layout, affecting illuminance lx-level and visual quality. This study evaluates minimalist lighting conditions and identifies the most efficient solution for uniformity in a workspace. It focuses on specific zones (accent light seating zone, task area, and circulation zones). Considering many factors, such as luminaire type, layout distribution, and quantity, influence illuminance levels and visual quality. The aim is to establish various innovative lighting layouts for multiple tasks in an open office, and identify key factors enhancing illuminance levels, distribution uniformity, and energy efficiency. This work utilizes Dialux-evo 10 simulation software to develop various strategies using different minimalist luminaires shapes, quantities, and layout distributions within an existing office in Masdar City, UAE to improve visual workspace performance. Two-strategies have created, analyzing current conditions and evaluating proposed lighting concepts by installing various artificial lighting types and designing different layouts for each workspace independently. The results emphasize the importance of different factors such-as light efficacy and fixed lighting approach in achieving required illuminance levels. The visual impact of each workspace is influenced by lighting uniformity, color, and distribution, a CRI of 80 or higher is preferred for accurate color representation. The type, quantity, and arrangement of luminaires play a crucial role in the overall visual outcome. The linear arrangement with batwing-shaped distribution Scenario-C achieves an acceptable illuminance level of 565lx, resulting in a reduction of approximately 10.9% compared to the regular arrangement of the base case.
