One of the most impactful changes to this credit from LEEDv3 is: "Structure and enclosure materials may not constitute more than 30% of the value of compliant building products." In my experience so far, this requirement plus the change to the regional attribute (100 miles and only as a multiplier of another attribute) make 25% very difficult, if not impossible, to achieve on most projects.

I am curious, has anyone achieved this credit? And if so, any tips?
