Participants can join the round table of their choice. Each roundtable leader will spend the first 15 minutes on a case study, lessons learned, or industry update. This will be followed by a 45-minute open discussion with all participants, moderated by the leader. The final 15 minutes will be used to identify 3-5 industry recommendations resulting from the group discussion. Key recommendations will be shared with the entire audience, and all roundtable recommendations will be included in the post-event report.

Deep retrofits require more than technical solutions. They demand adaptability as projects move from concept to construction. This session draws on experience from completed deep retrofit projects to explore how real-world conditions shape outcomes in ways early assumptions rarely anticipate. Using examples from the field, they highlight why certain strategies perform better than expected, where projects most commonly lose momentum, and how teams adjust to move work forward.
