This paper aimed to review the literature of the past ten years about the energy performance of buildings during their operational stage. The focus of this review was empirical works that examined the energy use in real buildings. An overview of the literature survey is presented. A meta-analysis technique allowed the identification of two approaches of study: building-level analysis and stock-level analysis. The building-level analysis considers the building as the system of study. Otherwise, the stock-level analysis considers a group of buildings as the subject of study while the buildings are elements inside the system. Notable research topics were addressed involving performance gap, energy audit, retrofit savings assessment, Zero Energy Buildings (ZEB), benchmarking, regulations and strategies to overcome climate change. This literature review summarised the level of information of the studies by listing the granularity of the energy performance data according to the purpose of the study. Furthermore, a specific section was dedicated to assemble the methods and tools adopted. Finally, we proposed conceptual models for both approaches (building and stock-level) that outlined the main aspects and dynamics identified in this literature review. Thus, we obtained insights to be investigated in further studies.
