Lesson 1: Key Updates to HPD Open Standard in v2.3

HPD v2.3 Key Updates

The HPD Open Standard v2.3 was released on May 12, 2022.  This part of the training will review these key updates to the HPD Open Standard.

HPD Version 2.3 introduces a number of new features, and important refinements to improve usability by both manufacturers and project teams. Highlights of the release are:

Visual Updates to Highlight Data Quality

An HPD is a  report from the manufacturer of product contents and associated health information. Part of what makes any published HPD credible to the users of this data is the manufacturer’s usage of the HPD Open Standard’s rigorous reporting methodology. The recognized orange-and-blue HPD format is a required part of a published HPD.

HPD v2.3 now requires a visual indicator that distinguishes unpublished or draft HPDs from a published HPD. An unpublished or draft HPD contains a “DRAFT Unpublished HPD” watermark on the document as well as a gray color. A published HPD will contain an orange color.

Increased Material and Substance Data Transparency and Quality

Key updates to “Alternative Materials and Substances,” “Content Differences,” and “Guidance for Substance Names” provide manufacturers with a clearer picture of the data quality requirements and best practices for producing high quality HPD reports.  

New data entry fields fit better specific kinds of material addressed in HPDC’s Special Conditions policies, i.e., wood, stone, mixed recycled content, metal alloys, fasteners, etc. The result will be that users of HPDs will no longer see confusing notations relating to “SCs” or Special Conditions. And manufacturers can inventory material content with data entry fields that fit the specific kind of material.

Data Consistency for Special Conditions

HPD v2.3 revamps data-entry for Special Conditions, introducing enhanced completeness checks, better data validation, and smarter policies. The update also provides visual consistency for Special Conditions with other content in an HPD.

Additional Listings Added to HPD v2.3

The “Additional Listings” section adds substance screening results for key restricted substances lists (RSLs) or other non-hazard listings that are complementary to the GreenScreen® for Safer Chemicals, GreenScreen List Translator™ and HPD Hazard Warnings results already reported in HPDs. The v2.3 release adds: Cradle to Cradle Certified Product Standard Restricted Substances List (Basic Screening), Living Building Challenge (LBC) Red List, US EPA Safer Chemicals Ingredients List (SCIL), Green Science Policy Institute Six Classes, REACH Exemption List, and Perkins&Will Precautionary List.  Additional lists will be considered for inclusion as proposals are made to the Technical Committee. 

Improved Procedures for Accessories

Having information on a product’s required accessories, such as an adhesive used to install a flooring product, gives HPD users a more complete picture of a product’s health information. However, this section of the HPD has not been frequently or consistently used by manufacturers. Our committees reviewed this issue and decided this information is important to users. The goal of v2.3 was to provide an easier and clearer way of adding accessory information.

This was done by adding a “Type” field which gives manufacturers more ideas on what to list and provides a clearer view of the product. Clarification was also added that allows manufacturers to use generic entries in the Accessories section.

Update to the LEED Pre-Check to Comply with LEED Version 4.1

Manufacturers will receive more detailed feedback on compliance of reporting with the HPD Open Standard v2.3. Program pre-check capabilities, which have been available for LEED v4, are being greatly expanded to enable pre-check for additional certification and rating programs, including LEED v4.1.  

LEED has been updated to LEED v4.1, while LEED v4 also remains in use. The LEED pre-check in the HPD Builder and Repository display should be updated accordingly. While some requirements for LEED remain the same from v4 to v4.1, LEED v4.1 introduces significant new pre-check requirements. Specifically, an analysis of the HPD content inventory, including percentage weights for ingredients and corresponding GreenScreen scores, is required to perform a complete pre-check.
