Application of circular economy principles in buildings: A systematic review

Abstract

The transition from linear economy into circular economy is not realizable until circular economy principles are applied into the life-cycle stages of buildings which is a proactive design approach to manage buildings from cradle to cradle. Resources are depleted without any effective programme for material recovering. Hence, this study was aimed at identifying suggested advancements for the application of circular economy principles in buildings. The study objectives were to systematically review/analyse proposed circular economy interventions in buildings and finally conclude on findings whilst identifying research gaps. Therefore, the study gathered related articles for review under seven identified major circular economy strategies. Results revealed that there was a progressive awareness/research on circularity in buildings although its awareness/acceptance were still at their infancy. Sixty-four articles were analysed under identified strategies, leading to discussion of major interventions. The review revealed practical approaches to the application of circular economy in buildings, also identifying aspects that received little attention, including research-gaps. It was recommended that future research should focus on obscured areas identified for a holistic approach. Conclusions were deducted from the analysis and recommendations made based on researchers work on the susceptibility of buildings to resource efficiency in a circular economy.
