The realization of energy efficiency targets in Europe requires renovation of 30 million buildings by 2050. Compared to new building constructions, there is currently very limited research-based knowledge concerning the challenges and solutions of achieving energy efficiency in renovation through the lens of the project delivery process. Hence, this study aims to fill this knowledge gap through a qualitative study, involving project professionals representing clients, designers, general contractors, building services contractors, and maintenance experts. To do so, 21 semi-structured interviews were conducted, and the extracted data were analyzed through thematic and content analysis methods. The findings reveal that high investment cost and an uncertain payback period for replacing the old energy system together with insufficient space for new building services systems and building protection issues for façade renovation seem to be the most critical challenges. Regarding the enablers, the interviewees frequently mentioned a competent maintenance workforce, practice-oriented training and education for maintenance and operation staff, and detailed as well as purposeful measurement/metering of energy consumption for achieving energy efficiency in building renovation projects. The findings highlight the significance of investing in people and technological solutions for realizing energy efficiency through building renovation.
