In the 3rd paragraph for BD+C and 2nd paragraph for ID+C replace the 4th-7th sentences with the following: "If optional products or materials are included in cost-based credit calculations, such as Option 2 under each Building Product Disclosure and Optimization credits, they must be included consistently across all cost-based credit calculations. Additionally, if optional products and materials are included in product based calculations, such as Option 1 under each Building Product Disclosure and Optimization credits, they are not required to be included in cost-based credit calculations. However, unlike furniture, if some of these products are included in credit calculations, not all products of that type must be included."
