The research examines various factors, including sky conditions, view types, window shading conditions, façade design elements like patterned solar screens, and the layout of office spaces, particularly within the framework of Activity-Based Working (ABW) environments.The initial phase of the study focuses on how environmental and contextual factors such as sky conditions and space functions influence indoor occupant perception. Findings reveal that sky conditions and space functions impact indoor occupant perception which then impacts environmental adaptation in the form of window blind use. A consistent preference for half-closed blinds was observed, reflecting a universal desire to balance privacy with natural views. The dissertation then progresses to analyze the perceptual impact of façade designs, demonstrating that traditional solar screen patterns, such as mashrabiyas, influence occupants' views and perceptions of privacy. Moreover, these screens' pattern complexity and occlusion percentage intricately affect satisfaction and view quality, emphasizing the need for a harmonious balance between functional and perceptual considerations in design. Further investigation into the human-built environment relationship led to the study of the impacts of environmental design on indoor occupant performance. Specifically, in office environment design via virtual reality simulations, the research assesses the impact of ABW office environments on cognitive performance and satisfaction. Quieter, privacy-conducive spaces such as Focus Rooms are shown to promote better performance and higher satisfaction, highlighting the inadequacy of Open Offices for focus-requiring tasks. The dissertation highlights the complexity of design and environmental factors in shaping occupant perception, environmental adaptation, and performance, advocating for a human-centric approach in architectural and interior design. It calls for future research to further explore the longitudinal effects of these design interventions and to consider the integration of emergent technologies for enhancing our understanding of environmental design psychology. Overall, the dissertation provides compelling evidence that thoughtful design can improve the quality of indoor environments, optimizing both the well-being and productivity of occupants. As the nature of workspaces continues to evolve post-pandemic, this research offers valuable insights for creating adaptive, supportive environments in line with the diverse needs of an ever-evolving workforce.
