Heritage buildings are crucial to the human perception of culture. Sustainable retrofitting of such buildings represents an opportunity for their reuse while considering sustainability. HBIM tools (Historic building Information Modeling) can be used as a comprehensive data set of information, related particularly to the restoration of buildings. The aim of this paper is to integrate HBIM tools in the application of sustainable retrofitting of heritage buildings through a conservation framework. The paper provides a literature review and a qualitative analysis of worldwide examples. Findings of this paper provide useful framework for sustainable retrofitting of heritage buildings in the Egyptian context.
