What is the credit range for MR Building Product Disclosure and Optimization - Material Ingredients?

The credit range for MR Building Product Disclosure and Optimization - Material Ingredients is indeed 1-2. This credit category encourages project teams to select environmentally preferable products that disclose their chemical ingredients and contribute to overall building performance and occupant health.

In particular, projects can earn one point for using products that meet the requirements for material ingredient reporting. An additional point can be gained by choosing products that utilize at least 25% of the total value of materials that support certain material ingredient optimization methods. This structured credit system aims to promote transparency in product ingredients and enhance the sustainability of building materials, fostering a healthier indoor environment.

The other ranges are not applicable to this credit as they do not align with the specific criteria outlined in the LEED V4 framework for this category of material optimization.
