The reliability, security, and sustainability of energy generation and supply are of global importance and the building sector accounts for up to 32% of total energy consumption, which makes it a key player in the domain. Previous research has identified that the actual energy consumption in buildings could be as much as 2.5 times of the predicted or simulated. This large building energy performance gap (BEPG) between the predicted and actual consumption has caused a significant problem for building energy supply and demand management and therefore have attracted increasing attention from researchers around the world. These researches have resulted in a large number of publications over the last decade. However, research has not reached the phase where the root causes of BEPG could be effectively identified, managed, and eliminated. There remains a lack of systematic and comprehensive review of the current literature to understand the current state of play, and set directions for future research. To fill this gap, in this paper, a thorough survey and review of BEPG research was carried out. The paper collected and analyzed 227 relevant publications and developed a framework for better understanding previous BEPG research. Subsequently, an in-depth analysis of BEPG research was conducted to explore its causes and corresponding strategies (including design concept, “hard” technologies and “soft” measures). Not only the interaction among causes but also the strengths and limitations of corresponding strategies were discussed in detail. Future research is finally recommended based on the limitations of exist strategies, including (1) building energy performance life-cycle thinking; (2) energy performance information integrity; (3) big data collection and analytical method; (4) stakeholders’ attributions, decision criteria and behavior; (5) stakeholder interactions; (6) modelling and simulation validation; (7) multidisciplinary approach; and (8) building system flexibility.
