The signature feature of HPD v2.2 is a new tool for incorporating supply chain information more directly into the HPD reporting process.
In a new innovation, HPD v2.2 distinguishes between two different forms of HPD: the Product HPD and the Supplier HPD.
- The Product HPD is the format that you have been familiar with if you have seen an HPD before. It reports on the contents of a complete product.
- The Supplier HPD contains some but not all of the data elements of a complete Product HPD. The Supplier HPD is a tool for ingredient suppliers to provide complete and accurate content inventory and associated health information data directly to product manufacturers for reporting in Product HPDs. As with the Product HPD, the Supplier HPD may provide hazard screening information while withholding proprietary substance identification, and be considered compliant with the HPD Open Standard if all other reporting requirements are met.
The 5,000+ HPDs published to date provide a treasure trove of data about materials and substances used in building products and materials. Several innovations with HPD v2.2 make that data more consistent, easy to understand, and useful for research.
- The previous “Role” field on the HPD has been renamed “Substance Role,” and manufacturers will select from a drop-down list with dozens of possible terms such as binder, flame retardant, surfactant, biocide, etc. More consistent use of this field is important to understanding how a substance is being used. As collective use of HPDs continues to grow, researchers can use that data to identify which substances are less hazardous for a given role.
- A new “Material Type” field will provide a broad classification of a material based on chemical makeup and molecular structure. Manufacturers will select from a list of options the most accurate classification describing a material. Typical entries may include Metal, Ceramic, Polymeric Material, Glass, etc. The purpose of this field is to help HPD users quickly read and understand an HPD. It provides an additional "signpost" to translate lists of technical substance names to readily understood terms for common material types.
- When manufacturers provide notes in the HPD with qualifications related to context, e.g., chemical exposure or risk assessment, the manufacturer will now be directed to provide specific citations to relevant published reports. This will support HPD users in researching and verifying Notes statements.
- All versions of the HPD are recognized for contribution to the LEED v4 and now LEED v4.1 material ingredients credits. HPD v2.2 remains consistent with LEED requirements, and HPDC regularly updates LEED v4 guidance to support updates in the HPD and in LEED.
- In response to manufacturer feedback, HPD v2.2 better recognizes the typical variation that occurs in products. There is now more clear and practical guidance (see Section 3 in the standard) on how to represent multiple related products on a single HPD. Most significantly, manufacturers of modular components or products with consistent composition but widely varying ingredient proportion to report these variations using a single HPD. Think of a company making cables that can vary from 1 to 50 meters long. Under previous versions of the HPD Open Standard, each incremental change would require its own HPD, even though it is basically the same product.
HPD v2.2 carries forward all updates made in previous versions of the HPD Open Standard. You can read more about the prior update, HPD v2.1.1, here.
