The effect of Changing Construction Materials on Historical Building Performance in Case of Restoration - Case Study of Al-Nabi Jirjis Mosque in Old Mosul City

Choosing appropriate construction materials in restoration processes of historical buildings particularly after wars or disasters is crucial in retaining the importance of such buildings and their distinct characteristics.This study is to explore how a change of original construction materials can influence energy efficiency and thermal comfort when rebuilding the destroyed historic buildings after the war in Old Mosul, where Al-Nabi Jrjis Mosque was selected as a case study.The study has adopted a comparative method between three simulation scenarios including two sets of new materials in addition to the original one.ENVI met analysis is used as a method to simulate the three cases.Results showed that the original set of materials (stone and plaster) has characterized by the best thermal efficiency compared by new materials used in the study.However, a set of hollow concrete with PVC strip used in one of the other scenarios revealed somehow good results, which therefore can be used as an acceptable alternative if the original materials are not available.
