The aspiration
A decade ago, a project team that wanted to know what was in a building product had almost nowhere to turn. HPDC set out to make that information complete, consistent and public.
The reality
18,500+
HPDs published, and counting
40,000+
products
1,200+
manufacturers, disclosed voluntarily
Now put it to work
The question now is what you do with it. Waiting until the data is perfect, or assuming disclosure is too hard or too expensive, is no longer a reason to stand still. Symposium VII shows the people who are already using it, and one thing every project team can do right away.
Keynote
Jean Hansen
What the HPD community set out to do, what it has accomplished, and why this is not the moment to be complacent. Jean was part of the work from close to the beginning.
Case studies
The 2026 All-Star case studies
HPDC General Members present the innovations, results and lessons from their material health practice, and receive the Materials Transparency All-Star Innovation Award.
Launch
Transparency in Action: Indoor Air Quality
The ingredient reporting already in HPDs lets project teams screen products and projects for substances that matter for indoor air, such as formaldehyde, as a baseline alongside the emissions testing LEED, WELL and other programs ask for. Where an HPD is missing, the next step is to ask the manufacturer for one. With a short demonstration in HPDC’s tools.
The full agenda and speaker list will be posted here.
Who should attend
- Architects, interior designers and specifiers
- Building product manufacturers, whether you publish HPDs today or are getting started
- LEED and WELL consultants and sustainability leads
- Owners, facility teams and researchers working on indoor environments

Registration is free and open to everyone.
