What about metal stud assemblies: how do we break down the calculation by area if portions of the assembly are removed (some light gauge framing, or plywood, or GWB, etc.)?

Can you give a more specific example? My initial response is that it would be a matter of degrees, i.e. after a certain point if you alter the assembly it does not count as reuse. Can you quantify how much of the assembly is being replaced?

Perhaps the best way to approach it would be if you touch it, it is not considered reuse. For instance, if we are placing a window into a wall without openings that is metal stud assembly (exterior envelope) we would count only the untouched portions of the exterior assembly (larger that just the SF of the window opening). Thoughts?

Hi John, It's always a safe bet to go with the intent of the credit, and with this credit, the calculation is geared towards the area retained. So, I would lean towards counting only the untouched portions of the exterior assembly. That said, there is an old CIR (ruling dated 9/19/2005) that allows for calculating the percentage of a wall section retained based on weight. If it gets down to the line, you could submit a CIR based on the same logic.
