Emerging Best Practices for Special Conditions
The HPD Open Standard v2.1.1 (Released 7/2/2018, Effective Date September 2018) introduces defined methods for the handling of certain Special Conditions when reporting Content Inventory for an HPD. Prior to the Effective Date for v2.1.1, these documents referenced below are provided for download and review. We invite your comments – email@example.com.
Emerging Best Practices supplement the information and requirements presented in the HPD Open Standard Instructions and Format, as an official element of the HPD Open Standard. For additional information about how Emerging Best Practices are governed as part of the HPD Open Standard, visit the Emerging Best Practices Landing Page by clicking on this link.
The HPD Open Standard, v2.1.1 outlines Guidance on Special Conditions, which includes the basic principles defining Special Conditions and instructions for reporting on Special Conditions materials and substances in the HPD. The Guidance provides details to support consistent and harmonized content inventory reporting for Special Conditions – materials and substances for which the typical content inventory approach is not adequate. The guidance also lists which programs were considered in working toward a harmonized content inventory approach for these materials.
Guidance on Special Conditions
Materials or substances may be included as special conditions for one or more of the following basic rationales. These general rationales are included here to support coherence as new special conditions arise and revisions are made:
- A content inventory cannot be created with methods outlined in the current version of the HPD Open Standard due to variable or unknown composition and lack of CAS RNs. For example, Biological Materials, Geological Materials, and Mixed Recycled Content.
- A content inventory can be created in theory with current HPD methods but it is not practical to do so and/or the value of trying to create a complete inventory is questionable. For example, Electronics if a minor component of the product.
- Programs using the HPD as an inventory reporting tool do not require CAS RN reporting. (HPD harmonization partners: ILFI Declare, Cradle to Cradle Certified™, BIFMA).
Over time, HPDC will work to develop additional requirements and more rigorous methods for identification and screening of these materials, as methods and knowledge evolves. These emerging best practices are expected to evolve concurrent with other programs, in support of further harmonization.
Scope of Special Conditions Guidance
Note that this guidance only addresses the reporting requirements that are different under Special Conditions. All other reporting requirements for Special Condition materials are as outlined in the current version of the HPD standard (e.g., role, amount, VOCs, etc.), and in guidance for specific programs using the HPD (such as LEEDv4 [https://www.hpd-collaborative.org/leed-v4-credit-achievement/]).
If the only content not characterized, screened, or identified is covered by Special Conditions, and Special Conditions best practices are followed, “Yes ex/SC” (Yes except Special Condition) will be checked and the HPD will not be barred from qualifying for the LEED v4 Materials and Resources Disclosure and Optimization credit, Option 1. To streamline LEED review, the Inventory and Screening Notes data field should include the following note: [LEED v4] “Yes ex/SC ” result is due only to materials and substances for which Special Conditions were applied. Thus “Yes ex/SC” does not disqualify the product for the LEED v4 Materials and Resources Disclosure and Optimization credit, Option 1.
Version control nomenclature
When guidance is established or revised for a Special Condition, a version nomenclature with date is provided. This nomenclature is independent of the current HPD Standard version, and must be referenced in the Material Notes field of the HPD. When updating an HPD, the most current guidance must be used, and referenced.
Special Conditions Guidance Available for the Following Special Conditions
Only materials and substances with approved Special Conditions Guidance can be treated as a Special Condition in an HPD. The following documents outline the instructions for reporting of Approved Special Conditions. Additional Special Conditions categories are under consideration by the HPDC Technical Committee, for future approval and inclusion in the HPD Open Standard. If you have a question about Special Conditions in the HPD Open Standard, please contact us at: firstname.lastname@example.org.
