Heritage Lanes, QLD, Mirvac 6 Star Green Star - Buildings v1

A rating tool for new buildings and major refurbishments

Why Green Star Buildings?

Climate action, resource efficiency and health & wellbeing are key megatrends changing the world as we know it. More and more companies are committing to climate action, as investors, consumers and employees expect more from companies than ever before. It's imperative that the built environment responds to meet the challenges of our time, or risk obsolescence.

Launched in 2020, Green Star Buildings has been especially designed to meet the challenges of the next decade, delivering assets that don’t just meet the expectations of today, but are also future ready and will withstand evolving customer demands, regulatory requirements and increased scrutiny against greenwashing. The biggest overhaul of the Green Star rating system in over 18 years, Green Star Buildings has been embraced by industry with over 400 new buildings registering under the tool – the fastest uptake out of all Green Star rating tools.

Whether you’re a developer, occupier, investor or leasing agent, Green Star Buildings will help you stay ahead in a changing world. Discover how Green Star Buildings can help you today. Download a brochure below or email to request a briefing. 

Green Star Buildings is a tool for our time. It encourages bold action to eliminate emissions and responds to the needs of building developers, owners, tenants and investors alike who no longer want just a great building, they want a great green building.

Key features of Green Star Buildings

Help future proof your asset

Green Star Buildings is a holistic tool that extends beyond the environment to address the issues that will define the next decade of the built environment. The tool’s 8 categories enable owners and developers to act on the areas of sustainability that matter most, future proofing a building for the long-term.

A clear path to reach your decarbonisation goals

Green Star Buildings includes the Climate Positive Pathway* - a clear set of targets aligned with the IPCC recommendations to help you deliver a Climate Positive building that’s fossil fuel free, powered by renewables, highly efficient, built with lower carbon materials and offset with nature. 

Access sustainable finance with ease

Any building that meets the Climate Positive Pathway automatically complies with the Climate Bonds Initiative, making attracting capital simpler than ever.

Fast, simple, streamlined reporting

Green Star Buildings has been specifically designed to align with leading frameworks, including the UN Sustainable Development Goals, GRESB, IPCC recommendations and the Task Force for Climate Related Financial Disclosure. The result? A project that aligns with expectations and makes the reporting process faster and simpler.

In a post-COVID world, healthier buildings are more important than ever.
