Design Rating
(Maximum)
Steel-framed: at least 50% of specified structural steel (by
weight) has 25% post-consumer recycled content or is reused
1
Concrete-framed: at least 80% of specified rebar or stressing
steel has 90% post-consumer recycled content.
Specified concrete mix and reduction in cement use will
1
achieve an embodied GHG of concrete as per table SM10.1,
rows B1, C1 and D1.
Specified concrete mix and reduction in cement use will
2
achieve an embodied GHG of concrete as per table SM10.1,
rows B2, C2 and D2.
At least 15% of all specified aggregates to be used for structural
1
or non-structural applications are recycled.
Only recycled aggregate is specified for use as base, sub-base
2
or backfill.
Cost of specified recycled materials equal to at least 10% of
1
Total Material Costs.

� Narrative listing all materials proposed for compliance with the Credit
Requirements;
� Calculations by weight (Recycled Steel), embodied GHG emissions (Cement
Replacement, using the Estidama Concrete GHG calculator), volume (Recycled
Aggregates) or cost (Other materials) demonstrating compliance with the Credit
Requirements; and
� Extracts from specifications detailing the use of compliant nominated materials.
� Updated narrative listing all materials used to meet the Credit Requirements;
� Updated calculations by weight (Recycled Steel), embodied GHG emissions (Cement
Replacement, using the Estidama Concrete GHG calculator), volume (Recycled
Aggregates) or cost (Other materials) demonstrating compliance with the Credit
Requirements;
� Proofs of manufacture for all nominated materials; and
� Proof of purchase for all nominated materials. For nominated ‘Other Materials’ the
proof of purchase should indicate the material cost (excluding labor and
equipment).
