Effective retrofits demand collaboration across sectors—building owners, investors, policymakers, and community stakeholders. This session will explore the key strategies needed to align these stakeholders, using real-world examples, innovative financing models, and capacity-building initiatives to drive action on multi-unit retrofits. Panelists will dive into how behavioral science can be leveraged to understand decision-making, the role of policy incentives in shaping retrofit adoption, and the importance of cross-sector collaboration in scaling solutions.
