Architects are increasingly navigating multiple sustainability and wellbeing frameworks, including Green Star, WELL, Passivhaus and the Living Building Challenge. While each system has a distinct origin, methodology and emphasis, there is significant overlap in their ambitions and outcomes. This Lean-In explores where these frameworks align, where they differ, and how architects can use them strategically to deliver healthier, more resilient and regenerative buildings. Rather than comparing rating systems as competing approaches, the session seeks to identify common goals, complementary strengths and opportunities for integration across projects. The discussion will be relevant to architects, sustainability consultants, clients, developers and project teams seeking to better understand how certification frameworks can support design excellence and positive outcomes.
