    Impact of Innovative Lighting Strategies on the Performance of Workplace Environment
    (SpringerLink, 2024) Tobeishat, Reema A.; Sheta, Wael
    Innovative 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.

    A Sustainable Approach to Improve the Interior Design of Existing Space: The Case of the BUiD Main Lobby
    (Springer Link, 2023) Aloudeh, Rahaf; Elmardi, Manar; Sheta, Wael
    The Interior designers’ role in the built environment is creating spaces that meet the needs of their clients through a process of critical thinking, research, and creative solutions. In addition to considering other aspects such as the client’s health, safety, and wellbeing as well as the environmental impact which is considered a sustainable thinking by the designer. This paper will focus on analysing the interior characteristics for a space in an educational building. The study will thoroughly explore the existing condition of the chosen space, identify and analyse the raw materials, manufacturing methods, transportation, use, maintenance, and disposal of all the furnishings, fixtures, and equipment specified for an interior environment. Subsequently, the proposed strategies and methods will be presented to replace the existing conditions with sustainable alternatives. In addition to propose options for an alternative design that follows more sustainably responsible practices using the life cycle approach, explaining the solutions that could be used to improve sustainability of the chosen building interior space.
