This credit relates to the engineering design of the project and up to one point is available when there is a reduction in the mass of steel framing used when compared to standard practice. The reduced mass can be demonstrated either by:
The Life Cycle Impacts point for the use of high-strength steel can be awarded if the project team can demonstrate that:
The Life Cycle Impacts point for reduction in mass can be awarded if the project team can demonstrate that the project results in a 5% or more reduction in mass of steel framing when compared to a suitable reference case building.
To demonstrate compliance a qualified structural engineer must submit the following:
