Everything You Need for LEED v5
Specifying flooring for a LEED v5 project means selecting products backed by verified documentation that satisfies the Building Product Selection and Procurement credit. Stonhard's seamless flooring systems come with third-party-verified EPDs, HPDs, and CDPH certifications, giving your team the transparency to pursue credits with confidence.
Stonhard offers EPDs across a range of flooring systems, with verified lifecycle data, including Global Warming Potential (GWP) values that let you compare each system's carbon footprint against project benchmarks. From Stonclad UR for industrial spaces to Stonres RTZ for healthcare and Smooth Mono for commercial lobbies, you can access the documentation you need to meet LEED v5 requirements.
Below find Stonhard's sustainability documentation in one place, so you can confirm compliance, compare products, and move your project forward. Need additional documentation or have questions? Stonhard's architectural and design representatives are ready to help.
Stonhard CDPH Standard Method V1.2 (CA Section 01350) VOC Emission Certificates
Acceptance criteria: ½ Chronic REL for individual VOCs of concern, and ≤9.0 µg/m³ formaldehyde — evaluated for School Classroom and Private Office exposure scenarios. Tested by Berkeley Analytical.
Stonhard CDPH Standard Method V1.2 (CA Section 01350) VOC Emission Certificates
Acceptance criteria: ½ Chronic REL for individual VOCs of concern, and ≤9.0 µg/m³ formaldehyde — evaluated for School Classroom and Private Office exposure scenarios. Tested by Berkeley Analytical.
How To Use These Resources for LEED v5
Stonhard's Environmental Product Declarations (EPDs), Health Product Declarations (HPDs), and CDPH (California Department of Public Health) emissions certifications give project teams the verified data they need to help earn LEED v5 credits for your project. This guide explains which credits apply and how each document supports your LEED documentation.
Three LEED v5 credits fall within scope when you specify Stonhard flooring systems. Use the sections below to match each credit with the right resource.
Credits Stonhard EPDs, HPDs, and CDPH Emissions Certificates Support
| LEED v5 | Type | What a Stonhard Documentation Does |
|---|---|---|
| Building Product Selection and Procurement (BPSP) | Criteria under Material and Resources (MR) Credit | A product-specific Type III EPD achieves Level 1 compliance automatically. An HPD adds Human Health points for material transparency. |
| Quantify and Assess Embodied Carbon | Prerequisite (mandatory) | Supplies verified flooring data from the product-specific EPD so your team avoids conservative default values. |
| Low-Emitting Materials (MRc3) | Credit | CDPH (California of Public Health) emissions documentation shows the flooring meets the low-emitting criteria for this credit. |
Before You Start: Download these Documents
Gather the following resources from the Stonhard LEED & Sustainability hub or Stonhard product page for the specific flooring system you plan to specify:
- Product-specific Type III EPD (third-party verified), which provides the global warming potential (GWP) and life cycle data of Stonhard products and systems
- Health Product Declaration (HPD), which discloses material content and associated health hazards
- CDPH (California Department of Public Health) v1.2 Emissions Certification,which confirms the products have passed rigorous testing for long-term VOC emissions
Building Product Selection and Procurement (BPSP)
This rewards teams for selecting products with transparent, verified environmental and material health data.
A product-specific Type III EPD satisfies Climate Health criteria for this credit automatically. Stonhard's HPDs strengthen your submission further by documenting material health transparency, helping you to earn credit multipliers in this category.
Quantify and Assess Embodied Carbon
This is a mandatory prerequisite. Every LEED v5 project must complete it, and flooring is explicitly tracked within the embodied carbon assessment.
Here is why the right data matters. When a project team cannot supply a product-specific EPD, the assessment defaults to conservative EPA values. Those default figures are intentionally high and make the flooring appear to perform worse than it actually does. A Stonhard product-specific EPD replaces those defaults with verified, accurate numbers for your embodied carbon documentation.
Low-Emitting Materials (MRc3)
This focuses on protecting indoor air quality by limiting chemical emissions from products. Stonhard's CDPH (California Department of Public Health) emissions documentation demonstrates that the flooring meets the low-emitting criteria. Unlike the EPD, which supports embodied carbon scoring, and the HPD, which supports product procurement and human health transparency, the CDPH declaration aligns specifically with the low-emitting materials pathway. It verifies that the product has been tested for volatile organic compound (VOC) emissions and meets the thresholds LEED v5 requires for healthier interiors.
Need a Specific EPD or Have a Question?
If you cannot locate the EPD, HPD, or CDPH v1.2 Emissions Certificate for a particular Stonhard flooring system, or you need help confirming a GWP value for your embodied carbon assessment, contact your Stonhard architectural, design, and engineering representative. Our experts can provide the current documentation and walk you through the data your project team needs.
