Brownfield sites often contain existing buildings and during regeneration the decision to demolish or adapt them should consider sustainability principles. This paper discusses decision-making criteria obtained through a literature review and primary research including 18 interviews, 2 workshops and 2 focus group discussions. The most frequently mentioned criteria including building condition; heritage value and capital costs are evaluated. Criteria are then analysed from different stakeholder perspectives and the paper identifies where stakeholder values align. The paper forms part of a three year research project which aims to develop a decision-making framework to assist with integrated and holistic decision making.
