METHODS FOR MEASURING AND ASSESSING NATURAL LIGHTING INDICATORS IN INDOOR SPACES

This article examines the theoretical and practical aspects of assessing natural lighting conditions in indoor environments. It discusses the influence of daylight on human health, visual performance, productivity, and indoor hygienic conditions. Particular attention is given to illuminance measurements using a luxmeter, the calculation of the daylight factor, and the application of modern computer-based modelling techniques. The article also considers the principal architectural and environmental factors affecting daylight penetration, methods for interpreting measurement results, and practical recommendations for improving natural lighting in residential, educational, and working spaces. The study emphasizes the importance of combining instrumental measurements with appropriate assessment criteria to ensure reliable conclusions about indoor daylight conditions.
