Heritage conservation and energy efficiency in adaptive reuse projects the case of Gaziantep, Türkiye

PurposeThis article explores the challenges and opportunities in adaptive reuse projects for historic buildings, focusing on the interrelationship between energy efficiency and heritage conservation.Design/methodology/approachThe study utilises a mixed-method approach, including semi-structured interviews and energy retrofit surveys, conducted in seven adaptively reused historical buildings in the Bey neighbourhood, Gaziantep, Türkiye. Thematic analysis is used for interviews, and survey results were discussed together within the framework of CSN EN16883.FindingsThe adaptive reuse of historic buildings can result in economic, social, cultural and environmental benefits for local communities. However, for this to occur, careful consideration must be given when selecting the new function, ensuring that it aligns with the buildings' environmental performance potential and the community’s needs. Considering the CSN EN16883 Guidelines for improving the energy performance of historic buildings, when the retrofits made by the users are assessed, the general approach is to preserve the heritage value of the building rather than making it energy efficient.Originality/valueThis study will add to a cross-cultural understanding of the complex relationship between adaptive reuse, energy efficiency and heritage conservation by looking at the local context of Gaziantep. No similar qualitative study addresses this issue in this region.
