Indoor air quality (IAQ) is a critical determinant of occupant health, well-being, and productivity in educational settings, yet modern energy-efficient designs often compromise IAQ by limiting natural ventilation. This study investigates the architectural influence on IAQ in two prominent institutional buildings in Lucknow, India: The Faculty of Architecture and Planning at Dr. APJ Abdul Kalam Technical University and the Faculty of Architecture, Planning & Design at Integral University. Through continuous, year-long monitoring of key IAQ parameters (including CO2, PM2.5, PM10, and volatile organic compounds) using real-time sensors and by administering occupant satisfaction surveys, the research examines how design elements such as window orientation, ventilation strategies, and material selection affect indoor environments. A thorough review of existing literature underscores that natural light, biophilic elements, and proper spatial arrangements can reduce stress and improve overall health; however, gaps remain in understanding the combined effects of these factors in composite climates. Analysis of the collected data revealed that spaces with strategically placed windows and optimized natural ventilation consistently achieved lower pollutant levels and enhanced thermal comfort. Occupant feedback further supported the quantitative findings, indicating higher satisfaction and productivity in areas with improved IAQ. Based on these insights, the study proposes design recommendations that include the adoption of mixed-mode ventilation, climate-responsive facade designs, and the integration of sustainable, biophilic features to create healthier, more sustainable educational environments. Overall, this research provides an integrated framework for rethinking architectural design to balance energy efficiency with superior indoor air quality, with significant implications for building design in both urban and suburban contexts.
