This paper evaluates the impact of various retrofit strategies on the operational performance of mosque buildings. The research evaluates different retrofit strategies using decision-making techniques to reach the optimum strategies that could be applied to enhance the performance of the mosques and maintain the users' comfort as well. This is achieved through a defined framework that involves four main stages: 1) site investigation with the usage of 3D laser scanning for electronic building documentation and an energy audit to identify the main factors that affect the performance of mosques; 2) developing the BIM model for the whole mosque using the processed point clouds generated from the laser scanning in Autodesk Revit software and performing detailed energy analysis to assess the current mosque’s operational performance using IESVE software; 3) analyzing different retrofit strategies to assess their impact on the mosques’ operational performance with respect to the total energy consumption, thermal comfort, heat gains and daylighting performance; and 4) assessing the identified retrofit strategies to select the best retrofit scenario that could be applied to enhance the operational performance of the mosque using Analytical Hierarchy Process (AHP) and TOPSIS decision-making techniques. To demonstrate its primary features, the framework is applied to an actual case study, the Imam Al-Hussein Mosque in Cairo, Egypt.
