HPDc contributes to the MR credit — Building Product Disclosure and Optimization – Material Ingredients portion of a LEED V4 Project. HPDc published in the HPD Public Repository under any version can contribute: HPD 1.0, 2.0, 2.1, 2.1.1, and the most recently released version, 2.2. Guidance for applying the LEED requirements to each HPD version is available below in both visual and text formats. Use of Health Product Declarations (HPDs) is one of the most common and easy ways of gathering documentation for compliance with LEED v4 MRc: Building Product Disclosure and Optimization: Material Ingredients. HPDs also contribute to the same credit in LEED v4.1.
