Green Star™
BlueScope's environmental and sustainability credentials are recognised by a number of national and international green building rating tools and schemes, including Green Star™.
Launched by the Green Building Council of Australia (GBCA) in 2003, Green Star is an internationally recognised rating system setting the standard for healthy, resilient, positive buildings and places. Developed for the Australian environment, Green Star has certified thousands of sustainable fitouts, buildings, homes, and communities across the country.
The Green Star rating tools assess the sustainability attributes of a project through impact categories. Each category groups a number of issues related to a certain sustainability impact; these are known as ‘credits’, for which varying numbers of points are awarded. Each credit defines a clear outcome that a project must meet. Once all credits are assessed, the total number of points achieved is tallied and a certified rating may be awarded.
There are various Green Star rating tools, including Buildings, Design & As Built, Communities, Homes, Interiors, Performance, and Railway Stations.
How can steel manufactured by BlueScope in Australia assist in gaining Green Star credits?
The inherent properties of steel - strong and durable - translate to a range of design possibilities that can help accrue points under Green Star credits.
Steel can be an ideal material for adding volume to existing buildings and can allow historic facades to be incorporated into new designs. The durability of steel also allows it to be successfully used in adaptive reuse and designs for disassembly.
The strength-to-weight ratio of steel also means that large spatial volumes can be enclosed in a single space which, along with other design factors, can translate to better levels of natural ventilation, light, heating, and cooling. This can help improve both energy efficiency and indoor environment quality.
COLORBOND® steel with Thermatech®1 solar reflectance technology may also help accrue points in the Heat Island Effect / Heat Resilience credits by helping to reflect the sun’s energy away from the roof and the building, which could help to reduce the energy use associated with mechanical air conditioning.
Notes:
- COLORBOND® steel for roofing and walling's core colour range in the Classic and Matt finish (excluding Night Sky®) features our scientifically designed Thermatech® solar reflectance technology. Thermatech® technology may not be available in other colours, and is not included in COLORBOND® steel Metallic, COLORBOND® Coolmax® steel, COLORBOND® Intramax® steel or SUPERDURA® Stainless steel. Further information is available in this article on STEEL SELECT®. Results will depend on roof colour, level and location of insulation, type and location of building shape and function.
Green Star - Responsible Products Framework
A number of BlueScope products have an Environmental Product Declaration (EPD) and GreenRate™ Level A certification, and all are made from steel manufactured at Port Kembla Steelworks, a ResponsibleSteel™ certified site. All of these are recognised initiatives within the Green Star rating tools and may contribute to a project’s Green Star rating through the Responsible Products credits, provided proof of certification is included in the Green Star submission.
BlueScope has published an informative flyer about the Green Star Responsible Products Framework. It helps to simplify the program and guide stakeholders on how they may earn Green Star points by using BlueScope products. Download PDF: The Green Star Responsible Products Framework - BlueScope Products.
More information on initiatives and how products can contribute to a Green Star rating can be found at Responsible Products Framework | Green Building Council of Australia (gbca.org.au).

A number of BlueScope products have an Environmental Product Declaration (EPD) and GreenRate™ Level A certification, and all are made from steel manufactured at Port Kembla Steelworks, a ResponsibleSteel™ certified site. A combination of these initiatives can help in meeting the responsible product value (RPV) for a "Best Practice" product.

Good Practice Products:
|
All BlueScope products made from steel manufactured at the Port Kembla Steelworks in NSW come from a ResponsibleSteel™ certified site, meeting the responsible product value (RPV) for a "Good Practice" product.
|
BlueScope is also a verified steel manufacturer under the Steel Sustainability Australia (SSA) certification program. A number of BlueScope products are verified as meeting best practice ESG standards (SSA Credit 4.1) in the manufacturing of semi-finished steel products, which can be of help to fabrication and downstream processing businesses seeking SSA certification.
SSA certification is recognised under the Responsible Products Framework. Products supplied by steel fabricators and downstream processors with SSA Level 3 certification are recognised as “Best Practice Products”, while those that achieve SSA Level A2 and Level 2B certifications are considered “Good Practice Products”.
