The decision-making process in adaptive reuse projects is often complex, involving multiple and conflicting criteria, and diverse stakeholders. The aim of this paper is to provide a stateof-the-art overview of the decision criteria throughout the adaptive reuse process. An integrative literature review with a systematic search strategy is used as a research methodology to find and structure relevant decision criteria. Three phases in which decision criteria can be used in the adaptive reuse process are substantiated(pre-project phase, preparation phase, and post-completion phase). For each phase, a lists of decision criteria is established across different categories. While this review shows similarities between the different phases, with a predominant repetition of economic and architectural categories, more specific environmental decision criteria, especially in the implementation phase, are still overlooked. This findings highlight the need for more research on circularity in the AR process, with particular attention on evaluation methods and on the implementation phase. This phase is poorly understood, yet crucial for circular practices such as disassembly. This study contributes to the growing literature on adaptive reuse by offering a more holistic outlook on the multi-criteria decision making process.
