Abstract: Traditional dependence on Daylight Factor (DF) and thermal charts in daylighting and thermal simulation is challenged by holistic Building Information Modelling (BIM) tools. Nevertheless, BIM-enabled performance simulation for schools is scarce in literature, especially in hot arid zones. This research proposes a daylighting and thermal comfort optimization model for school buildings in hot arid climate. Considering Window-to-Wall Ratio (WWR) and building orientation angle as the decision variables, optimum designs are identified based on multiple criteria, ranked using the Analytical Hierarchy Process (AHO), and expressed using a holistic Criteria Combined Score (CCS). Three case studies are presented, criteria AHP weights are verified arithmetically, and results are validated using questionnaires. Increasing WWR from 5% to 29%, irrespective of orientation, increased CCS by almost 30%.
