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

According to the simulations performed using DesignBuilder software, the fourth case achieves the case achieves the minimum total energy consumption of 443,338 Wh/m annually, which corresponds to minimum total energy consumption of 443,338 Wh/m2 annually, which corresponds to an an 8.3% reduction compared to the base case, which is attributed to the minimum U8.3% reduction compared to the base case, which is attributed the minimum U-value
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Heritage buildings are integral parts of modern life, in which they gain their significance from their historical, archeological, and cultural added value, and signify the rich histories of countries [1,2,3,4]. Heritage buildings are recognized for their abilities to improve the cultural and architectural significance of societies [5]. It is found that existing buildings contribute to 40% of the total primary energy consumption and 36%
