INDOOR LIGHT ENVIRONMENT
Sara NESIMI MURADI
Abstract
Indoor lighting is a huge determinant of human health, human productivity and also human well-being. We as humans are spending more than 90% of our lives within the four walls of any enclosed place, out of which the intensity, density and the quality of the artificial light is becoming a subject matter of concern. This study aims to examine the effect of indoor lighting conditions on the comfort, behavior, and productivity of inhabitants in residential and institutional buildings in Tetovo. By using a mixed-methods approach the research combines physics-based measurements of natural and artificial illumination levels with qualitative information attained via semi-structured interviews. The findings demonstrate that the availability of natural light plays a major role in the occupants visual comfort and mental well-being, especially in the perimeter zones, whereas artificial lighting commonly does not fully respond to the users needs in the core areas. Seasonal and cultural differences were found to be significant in terms of preferences for lighting, necessitating lighting solutions that are adaptative and contextually aware. It is noteworthy that user satisfaction is influenced by a trade off between energy save and personal comfort which is inevitable as eco- friendly technologies, such as LED lighting and automated control, are actively promoted for sustainability purpose in the lighting environment. This research highlights the necessity of planning indoor lighting scenarios that, apart from efficient, are user-oriented, culturally-tailored and biocultural, directed toward healthier and more productive indoor environments. The findings highlight the importance of integrating design strategies in lighting systems to offer comfort, support energy efficiency goals, and accommodate seasonal and cultural variability in users preferences.
