The inaugural Reshaping Existing Buildings (REB26) conference in Melbourne focused on the retrofit challenge facing Australia's built environment. With 80% of today's buildings still expected to be standing in 2050, the event highlighted three key opportunities: better energy data, a shift to valuing existing assets, and closer collaboration across stakeholders. Key takeaways include that NABERS-rated commercial buildings achieved a 33% average energy reduction over 10 years, and that only 22% of buildings currently have access to energy profile data. Presenters also stressed the need for circular economy thinking and grid flexibility as the grid decarbonizes. The conference brought together engineers, facility managers, and property owners to share real-world retrofit success stories.

80% of buildings still standing in 2050 is a big number. Good to see NABERS getting credit for actually cutting energy use 33% over a decade. That's measurable.

The 22% data access stat is the real bottleneck. You can't manage what you don't measure. HVAC analytics adoption is still too low for deep retrofits to scale.

Circular economy talk is nice but without regulation on recycling and reuse, it stays aspirational. The panel on circularity called that out directly.

Grid flexibility panel is what caught my eye. As the grid decarbonizes, buildings need to shift load. Time of use NABERS ratings would actually drive that.

Key point from the article: retrofit projects face non linear decisions and competing budgets. That's the real barrier, not tech. Good they addressed business case challenges.
