The Health Product Declaration is an open, standard format for reporting product content and associated health information for building products and materials. HPDs are created by manufacturers using a standard template and does not require third-party verification.
When completing an HPD, manufactures can choose their level of disclosure, but it should be noted that only disclosure at 1000 ppm and 100 ppm are considered full disclosure per LEED v4.
The information presented in an HPD can be used to evaluate product options, along with considerations not included in an HPD such as environmental health, social sustainability, technical performance and cost.
An important note: the HPD reveals only product contents as it is delivered to the site. Substances of concern which are used in processes, exposing workers and communities during extraction and manufacturing, and byproducts of the manufacturing process are not represented here. For more information on the HPD refer to the Health Product Declaration Collaborative.
HPD and LEEDv4
The LEEDv4 credit ‘Building product disclosure and optimization – material ingredients’ rewards the selection of products which have compliant HPDs. A compliant HPD provides full disclosure of known hazards and demonstrates the chemical inventory of the product to at least 0.1% (1000 ppm).
