A comprehensive review on building energy saving during the past decade

With the shortage of energy and the promotion of environmental protection awareness, building energy saving (BES) has caused great concern in the world, the research related to BES is more and more. It is vital for interested researchers to get the full picture of global research. However, the current research review in the field of BES mainly focuses on the application summary of single BES technology, and there is a lack of summary of other latest research progress in this field, which makes it difficult for new researchers to clarify the development status and future research direction in the field of BES. Based on a review of the literature on BES published from 2010 to 2020, combined with bibliometric analysis and science mapping, this paper discusses the research trend in the field of BES in the past decade, as well as the co-authorship and influence of countries or regions, authors. This paper summarizes the main trend and deficiency of the current research on BES around three themes: energy saving design methods, energy simulation and optimization, energy measures drive and barrier. Future potential research directions are proposed, including: focus on the life cycle assessment of BES measures, the research about accuracy of energy performance evaluation, the intelligent integration of energy simulation software and cost evaluation, the research about influence factors of energy saving measures drive and barrier as well as the quantitative research of interaction relationship.
