Projects that use steel have the potential to earn up to two Green Star points. The ESC provides for one of these points – the Mat-5 Steel point in the GBCA credit for Responsible Building Materials.
This Green Star point can be gained where at least 95% of the building’s steel (by mass) is sourced from a Responsible Steel Maker and 60% of the fabricated structural steelwork on the project is supplied by a steel fabricator or contractor certified to the ESC. In other words, this point is provided to the constructor:
A Responsible Steel Maker is one who has:
The criterion for the responsible sourcing of steel does not attract a point but is a prerequisite for qualification of the project under the ESC point.
The relationship between fabricator and steelmaker is illustrated in the table below:
|Green Star point or contract requirement for environmentally fabricated steelwork||The fabricator/ contractor for the steelwork|
Continuous environmental improvement and commitment to sustainability, environmental responsibility and communication of this commitment through operation of a management system audited annually.
|Prerequisite: Responsible sourcing|
The steelmaker must operate to an ISO 14001 Environmental Management System and be a member of the World Steel Association’s Climate Action Programme.
