Lighting plays a crucial role in shaping learning environments, particularly in architecture education, where precision, focus, and sustained cognitive engagement are essential. This study examines the effects of natural and artificial lighting on the productivity, concentration, and well-being of architecture students at Mapua Malayan Colleges Mindanao. A quantitative, comparative research design was employed, with 50 students assigned to drafting classrooms with either natural or artificial lighting. Data was collected through a structured survey measuring productivity, concentration, and mood, followed by statistical analysis using independent samples t-tests. Results indicate that students in naturally lit classrooms reported significantly higher productivity, concentration, and mood compared to those in artificially lit environments. While efficiency and error rates showed no significant differences, students in naturally lit classrooms took fewer breaks and reported higher energy levels. These findings highlight the importance of optimizing lighting conditions in educational settings to enhance student performance and well-being. The study contributes to the broader discourse on architectural lighting design, emphasizing the need for balanced integration of natural and artificial light to support cognitive function and learning efficiency.
