The building industry is faced with a vast stock of existing buildings that are not sustainable and suffer from poor conditions in terms of physical problems. Energy retrofitting of existing buildings is considered as a rational strategy to minimize buildings’ environmental impact in the long term. Standard building retrofits focus on prescriptive measures to comply with energy standards rather than occupant requirements. In contrast, the proposed performance-based retrofit approach focuses, primarily on indoor comfort to leverage the non-energy benefits of retrofit besides the strategies to improve the energy performance of the building. Specifically, in the case of office buildings, most of the energy saving op tions and required high levels of indoor comfort are in conflict with each other and need to be balanced. This study argues the current approaches to the façade retrofit decisions in the case of existing office buildings in mixed-dry climates by incorporating both values of energy efficiency and indoor comfort issues considering different office spatial organizations. The main contribution is presenting the state-of-the-art in building energy retrofit and proposing a performance-based façade retrofit framework, which can be used by stakeholders and end users throughout the initial stages of a retrofit process. It can also form the basis of decision support tools that can be developed in the future.
