| description | Artificial lighting is a crucial component of office environments and a significant energy consumer. Effective lighting design in offices must balance the well-being and visual comfort of workers with energy efficiency. Therefore, designers need more focus on lighting design for providing more eye-comfort space for workers who spend most of their time in office. This study examines various artificial lighting distributions and fixtures concerning their potential for energy savings and visual comfort. Utilizing a quantitative research approach, both literature review and simulations were conducted. Four recommended lighting fixtures, each with similar power and flux and different shapes from different brands, were selected for analysis. Small, medium, and big office rooms were modelled using the room index formula for diverse office layouts. The simulations of the offices with varied lighting fixtures were carried out in DIALux Evo 11. This study aims to find the optimal lighting fixture for energy saving in the workplace. The findings from the simulation indicated that as the room index increased, there was a slight reduction in both the illuminance levels and uniformity. While the illuminance levels remained above the standard, the uniformity fell short of the required standard. In accordance with the results of the analysis, the optimal choice for lighting in the rooms is a square lighting fixture, which fulfills the necessary standards across various room sizes. Based on simulation results, the recommended artificial lighting fixtures of brands can provide an energy-consuming environment, but they do not consistently ensure visual comfort across all office layouts. |
