This study aims to assess the potential environmental and
economic benefits of retrofitting a residential archetype
building under different scenarios. The study uses life
cycle performance approaches to carry on a retrofitting
scenario for an attached villa archetype in new cities in
Egypt. After identifying three levels of energy retrofit
measures (ERMs), a multi-objective optimisation
framework was developed and carried out upon the case
study model to optimise the Life Cycle Cost (LCC) and
the Life Cycle Carbon Footprint (LCCF). The results of
the study presented 4 different retrofitting scenarios with
various investment costs and significantly improved
operational costs and emissions
