An investigation into the technologies and methods for integrating natural and artificial lighting in office environments

Nowadays, individuals spend a significant portion of their lives in workplaces, with offices being among the primary work environments where employees spend the most time during the day. Therefore, the design of office spaces holds great importance. Lighting is one of the fundamental elements that must be considered in office design. Research has shown that lighting in office spaces is not only functional but also has a significant impact on office workers. Maximizing the use of natural lighting can positively affect human health and performance while also contributing to energy savings. In office spaces, proper zoning and sensor utilization in the integration of natural and artificial lighting can provide substantial savings. Through automation, control over the amount and timing of lighting in the space can be achieved, and artificial lighting can be customized according to users' needs and preferences. This thesis examines the technologies and methods used in the integration of natural and artificial lighting. The first section of the study explains the aim, scope, and methodology of the thesis. The second section focuses on the analysis of natural and artificial lighting types. The third section presents the conceptual framework related to lighting, performance measurement methods, and the integration of both lighting types. In the fourth section, lighting control systems that can be utilized in integration are discussed. Following the analysis of these control systems, an office building is examined as an example. In the case study, key considerations in zoning and sensor utilization are explored. Ultimately, the technologies and methods used in the integration of natural and artificial lighting are studied through an example building, and the findings obtained from the research are presented.
