If Sydney Opera House Can Get a Green Rating, Yours Can Too | Davina Rooney
June 17, 2026
Aaron and Tim sit down with Davina Rooney, CEO of the Green Building Council of Australia, to talk about sustainability at scale, fit-out waste and what existing buildings can actually achieve.
Welcome to another episode of Let's Talk Facilities. Aaron and Tim sit down with Davina Rooney, CEO of the Green Building Council of Australia, for a wide-ranging conversation on what sustainability actually looks like when you are responsible for an existing building.
From the Sydney Opera House earning a six-star Green Star Performance rating to the office waste that comes directly from fit-outs, Davina unpacks where the biggest opportunities are hiding and why facilities managers are often the most important people in the room when it comes to driving real environmental outcomes. She also talks through what is coming down the pipeline legislatively, how to build a practical climate resilience plan for your assets, and why the sustainability data your building is generating right now might be the best lead indicator of overall building quality you have.
