Heritage buildings in Egypt are facing significant challenges due to a variety of factors such as inadequate funding and financial limitations, lack of maintenance, and insufficient regulatory frameworks.(Osman, 2018)These buildings, many of which are of immense cultural and historical significance, are at risk of being lost forever if action is not taken to preserve them. Adaptive reuse is one of the keys to sustain those buildings, and to transfer its cultural and memorial identity for further generations. Adaptive reuse is a strategy not only for preserving, but it can be a part of the urban sustainability and regeneration. (Bullen & Love, 2016)It also can have significant environmental benefits by reducing the carbon footprint of new construction materials and reducing waste generated from demolition. As by repurposing existing structures, energy consumption and demand for new construction materials are reduced, and the environmental impact is minimized. (Fisher-Gewirtz man, 2016)The recent research work in this area focuses on the reduction of the operational energy of heritage buildings in order to step towards energy efficiency. However, there is a gap in addressing the issue of embodied carbon emissions in the whole life cycle of buildings which addresses the embodied energy of the materials, energy used during construction, and later the operational energy of the building. This study confirms that the adaptive reuse of heritage buildings, specifically those built between the 19th and 20th centuries, is a viable strategy to help in reaching the decarbonization targets for buildings through dematerialization while preserving cultural and memorial values. The methodology used in this research utilizes a whole life cycle assessment comparing the carbon footprint of rehabilitating a heritage building to the Abstract
9demolition and reconstruction of a new one in Cairo using LCA tools that take into account environmental impacts such as global warming potential, amount of embodied carbon emissions and the most contributing materials in these impacts. The expected outcome of the study is a method to estimate the embodied energy for rehabilitating heritage buildings using a number of case studies in Khedival Cairo, Egypt
