MR Credit: Optimized Building Products

Comment 1: in order to continue market transformation with LEED v5, we encourage that there be  a focus on both structural and nonstructural building products when considering product optimization. In LEED v5, there seems to have been a shift to only consider nonstructural building products in the optimization process. We suggest all building products be included as this is a great way to transform more responsible sourcing efforts for all product producers.

Comment 2: Concrete Sustainability Council (CSC) responsible sourcing certification pertains to sustainable sourcing and manufacturing practices for concrete. It addresses similar attributes to Cradle to Cradle certification. After mapping with Cradle to Cradle -to the rigor of CSC, we suggest the credits be provided for CSC certification as follows:

CSC Certified: Bronze – Climate Health=0.5; Human Health=0.5; Ecosystem Health=0.5; Social Health=0.5; Circular Economy=0.0

CSC Certified: Silver – Climate Health=0.5; Human Health=1.0; Ecosystem Health=1.0; Social Health=0.5; Circular Economy=0.5

CSC Certified: Gold or Platinum – Climate Health=1.0; Human Health=1.0; Ecosystem Health=1.0; Social Health=1.0; Circular Economy=1.0
