Abstract

The building industry has partially shifted its focus in the past few years to making changes to the stock that comprises current city buildings. In fact, it is widely acknowledged that the core of the construction sector’s restructuring must be the renovation of existing structures and the implementation of sustainable urban regeneration. Presently, maintaining sustainable urban growth necessitates making improvements to already existing structures, which eliminates the need for new city expansion, as well as clearing preexisting neighborhoods. Additionally, taking into account the entirety of its lifespan, it is widely known that the construction industry contributes significantly to greenhouse gas emissions. As a result, ecologically friendly building materials and techniques are necessary along with circular economy and resource-efficient concepts to help society attain a level of decarbonization. This study aims to clarify the framework and highlight factors that must be taken into account to produce a building stock that is both circular and low carbon. To accomplish circular reinstatement procedures, which minimize waste and facilitate recycling and waste reduction practices, new business models, rules, and connections must be established. An in-depth analysis of the literature is done for a broader understanding. The paper also addresses the significance of the ecological evaluation of circular methods, highlighting the decision-making processes and decision-makers who can choose circular strategies for a sustainable reconsideration process with the aid of ecological and economic life cycle analysis tools.
