Studying Energy Performance and Thermal Comfort Conditions in Heritage Buildings: A Case Study of Murabba Palace

Heritage buildings are significant historical and architecture added value, which requires deep precise preliminary brainstorming when considering upgrading or retrofitting these valuable buildings. In this study, we opted to highlight some passive design interventions improve the thermal comfort required cooling energy for The Murabba Palace in Riyadh was selected as a case study. DesignBuilder software used evaluate performance of ten architectural alternatives throughout different seasons an attempt heritage scenarios encompassed double low-E glass, reflected glass wall with air gap, insulation, lightweight sprayed foam insulation. results show that using applying polystyrene insulation can enhance inside building reduce CO2 emissions 17% 9%, respectively.
