Résumé : Energy retrofitting standards and guidelines, together with benefitting from bestexisting experiences, are effective in retrofitting heritage buildings towards low-carbonemissions. In Downtown Cairo, many heritage buildings are exposed to adaptive reuse practices,after moving to the ‘New Administrative Capital’. Integrating energy saving in said practiceshas become a crucial aspect. Therefore, the aim of this study is to evaluate a recent retrofittedheritage building called ‘La Viennoise’ as an example of best practice for retrofitting processesin Downtown Cairo. The study carried out a field survey for data gathering. A monitoring-basedsimulation model was created and calibrated, and the building envelope and energy use wereevaluated. The simulation results are presented into two cases. The first includes the originalstate as a base case, showing a very low building envelope thermal performance. The secondincludes the current state as an improved case. A comparison of both cases shows that theimplemented retrofitting scenarios in the case study effectively improved its building envelopeand reduced annual energy consumption, and CO2 emissions. This paper allows further benefitfrom such example by setting a retrofitting guideline to expand this concept in other buildingswith similar conditions to achieve a low carbon-built heritage.
