This thesis project was aimed at designing an energy efficient, intelligent and humancentriclighting solution for one of the steel manufacturing units of Sardogan Industryand Trade. The proposed lighting design will be used in order to reinforce a sustainable,digital and productive work environment in this family-owned business. To set thetechnical fundamentals for the new lighting proposal, the effects of industrial lighting onproductivity, well being and energy efficiency were researched. For future comparison, aversatile site analysis was performed to assess the existing working and lightingconditions of the space. This research was supported by an investigation of smartlighting fixtures and informal interviews with managers and workers from differentworkgroups. After reviewing the data gathered through research and analysis sections,an Industrial Internet of Things(IIoT) electric lighting system, 16 new skylights openings,and an experimental lighting control strategy was proposed. In addition to the increasein overall quality of lighting, advancements in the fields of energy sustainability anddigitalization could be observed. Also with the integration of a new lighting solution, adecrease in absenteeism and accidents was expected as well as an increase inproductivity and morale.

Lighting is one of the most important issues for the perception of the physical environment and the ability to perform. Lighting design of classrooms is therefore crucial to achieve the goals of education. The Swedish school aim to provide a working environment supporting every child. As children are individuals their perceptions and light preferences differ just as adults do. Accessibility to tools to be able to customize for the individual child are therefore important. To support our planet, every new product developed should be considered regarding sustainability.  This is particularly important of products designed for children as they are our future. This thesis will focus on finding a task light option suitable for the classroom environment. By researching literature, performing market research and conducting interviews with school professionals, important characteristics of a school task light were established. Based on the findings, a task light proposal was developed including the defined properties.
