Addressing Indoor Environmental Quality in an Educational Building in Saudi Arabia: A Case Study of the CAD College in Prince Sultan University-Female Campus

Attaining sustainable development objectives is a key goal of Vision 2030 in Saudi Arabia, including enhancing educational environments. This study evaluates indoor environmental quality (IEQ) at Prince Sultan University's College of Architecture and Design, focusing on visual and air quality following recent renovations that prioritized aesthetics over functionality. Empirical measurements of lighting and air quality were compared with user surveys. Findings indicate uneven lighting distribution, inadequate natural light, and artificial lighting inconsistencies, correlating with users' complaints of eye strain and discomfort. Air quality assessments revealed elevated levels of formaldehyde (HCHO) and volatile organic compounds (TVOC) in several classrooms, impacting occupant well-being. The study proposes design enhancements, including smart lighting control, improved ventilation strategies, and optimized daylight integration to align the indoor environment with educational standards and occupant needs. These findings establish a foundation for future research and retrofitting strategies to improve educational spaces in Saudi Arabia including Smart lighting control systems, adaptive daylighting solutions, material replacement initiatives, and advanced ventilation upgrades.
