Summary
A Health Product Declaration (HPD) is a standardized report that discloses what a building product is made of — its ingredients, associated hazards, and how thoroughly those ingredients have been characterized. Acelab integrates directly with the HPD Collaborative's public API to automatically pull this data into the Materials Hub, so you don't have to read raw HPD documents yourself.
This article explains what an HPD is, what data Acelab extracts from it, and which fields you'll find in your Schedules and on product detail pages.
What Is an HPD?
Think of an HPD like a nutrition label for a building product. Just as a food label tells you what's in your food, an HPD discloses what's in a material — its chemical ingredients, any hazardous substances, and how completely the manufacturer has identified and characterized those substances.
HPDs are published voluntarily by manufacturers and follow a standardized format maintained by the HPD Collaborative. Acelab pulls HPD data automatically from the HPD public API whenever a product has a publicly available HPD on file.
📍Note: Not all products have an HPD. Fields sourced from HPD data will be empty for products that don't have one. To check whether a product has an HPD, look for Health Product Declaration in the All Certifications field, or look for the downloadable HPD document in the Health Product Declaration attachment field.
Before You Begin
HPD-sourced fields are read-only. They are populated automatically and cannot be manually edited.
Data availability depends on whether the manufacturer has published an HPD and made it publicly accessible via the HPD API. Some manufacturers produce HPDs but restrict their availability — those products will not have HPD data in Acelab.
What Data Does Acelab Pull from HPDs?
Acelab surfaces the following data from HPDs:
Ingredient Disclosure Fields
These fields describe the completeness and transparency of a product's ingredient disclosures.
Field | What It Means |
Ingredients | The chemical ingredients listed in the HPD |
Contents of High Concern | Ingredients flagged as hazardous or of concern |
Disclosure Publicly Available | Whether the product's ingredient disclosures are publicly accessible via the HPD API |
Reporting Threshold Level | The minimum concentration threshold at which ingredients were reported — either 100 ppm, 1,000 ppm, or 10,000 ppm. A lower threshold means more complete disclosure. |
Disclosed | Whether 100% of ingredients are disclosed at the 100 ppm threshold |
Identified | Whether 100% of ingredients are identified by name |
Characterized | Whether 100% of ingredients are characterized by hazard |
Screened | Whether 100% of ingredients have been screened against hazard lists |
Third-Party Verified | Whether the HPD was independently verified by a third party. This is used in LEED v5 scoring. |
Emissions & LEED Fields
Field | What It Means |
VOC Content Material (g/L) | The VOC content of the product in its liquid state, measured in grams per liter. Used to evaluate LEED v4.1 low-emitting materials requirements. |
LEED Pre-checks | Whether the product has been pre-checked for LEED compliance, as reported directly in the HPD. This is the fastest way to confirm compliance without interpreting raw VOC values. |
Document Field
Field | What It Means |
Health Product Declaration | A downloadable copy of the product's HPD document, when publicly available. |
Where to Find HPD Data
On a product detail page (PDP): HPD data appears in the product's summary section, alongside other health and sustainability data.
In Schedules: HPD-sourced fields can be added as columns. Open your Schedule, click Fields in the top bar, and search for the field name you want to add. HPD fields are Acelab Default Fields and are marked with the Acelab logo.
For a step-by-step guide to adding VOC and LEED fields to your Schedule, see Understanding HPD-Sourced VOC and LEED Fields in Material Hub.
Outcome
Once HPD fields are added to your Schedule, you can quickly scan for products with ingredient transparency data, filter by disclosure completeness, and identify products that meet LEED or other health-focused criteria — all without leaving Acelab.
