Summary
LEED (Leadership in Energy and Environmental Design) is the world’s most widely used green building rating system, developed by the U.S. Green Building Council (USGBC). LEED v5, officially launched on April 28, 2025, is the most significant update to the rating system in over a decade. It restructures how building products contribute to certification — consolidating multiple fragmented materials credits into a single, unified framework focused on multi-attribute sustainability outcomes. This article explains what changed, what stayed the same, and how Acelab’s Materials Hub helps you navigate LEED product selection and documentation across all active versions. Both LEED v4.1 and LEED v5 are currently active. LEED v4.1 registrations remain open, and many projects already in progress will certify under v4.1. Acelab supports both versions simultaneously.LEED v5 Scoring in Acelab

How LEED Has Evolved: v4, v4.1, and v5
Think of each LEED version like a building code update — the foundation is the same, but the thresholds rise and the approach gets more sophisticated with each cycle.LEED v4 and v4.1: The BPDO Framework
Under LEED v4 and v4.1, product-related sustainability was addressed through three separate credits grouped under Building Product Disclosure and Optimization (BPDO):
In addition, Low-Emitting Materials under Indoor Environmental Quality (EQ) covered VOC emissions and content limits — a separate credit that overlapped with product selection.
The BPDO framework rewarded product counts and cost thresholds. For example, under v4.1, earning the EPD Option 1 point required documenting at least 20 qualifying products from 5 manufacturers. These three credits were pursued independently, and documentation was tracked separately for each.
LEED v5: One Unified Credit
LEED v5 retires the three BPDO credits and replaces them with a single, consolidated Building Product Selection & Procurement (BPSP) credit worth up to 5 points. Rather than evaluating products through isolated lenses (EPDs here, ingredient transparency there), BPSP evaluates every product across five interconnected criteria areas:- Human Health — ingredient transparency, indoor air quality, and occupant well-being
- Climate Health — embodied carbon, low-carbon manufacturing, EPDs
- Ecosystem Health — responsible sourcing, habitat impact, FSC, recycled content
- Social Health & Equity — fair labor practices, equity certifications
- Circular Economy — recycled content percentage, biobased content, end-of-life recyclability
What Changed for Reporting
LEED v5’s Three System Goals
Every LEED v5 credit — not just BPSP — connects back to three overarching impact areas:- Decarbonization — targeting reductions in operational, embodied, refrigerant, and transportation carbon emissions (~50% of available points)
- Quality of Life — occupant health, social equity, and resilient design
- Ecological Conservation & Restoration — protecting natural systems and biodiversity (~25% of available points)
How Acelab’s Materials Hub Supports LEED
Acelab centralizes product research, selection, and documentation for LEED-registered projects. Rather than hunting certifications across manufacturer websites and third-party databases, you can use the Materials Hub to find, evaluate, and track products across both LEED v4.1 and v5 in one place.Finding LEED-Contributing Products
Use Product Search to search by certification type. Acelab’s database includes EPDs, HPDs, C2C Certified, FSC Chain of Custody, and other certifications relevant to both BPDO (v4.1) and BPSP (v5). You can filter results by certification to build a qualifying product list for your project. For LEED v5 specifically, Acelab surfaces four data points for every qualifying product:
All of this data is calculated automatically by Acelab — no manual lookup required.
Tracking Products in Schedules
Once products are saved to a project, your Schedule becomes the working layer for LEED documentation. Add any of the four LEED fields as columns to compare products side by side, filter down to only LEED-contributing products, and build a product list that maps to your certification goals. Because LEED v5 rewards multi-attribute products, the LEED v5 Contributing Certifications column is particularly useful: you can immediately see which products carry certifications across multiple criteria areas — the ones that give you the most leverage per product specified. For LEED v4.1 projects, the LEED Pre-checks column shows whether a product has been pre-checked for the Material Ingredients credit, saving the documentation verification step. See LEED v5 Scoring in Acelab for step-by-step instructions on adding and using LEED fields in Schedules.Viewing Data on the Product Detail Page
Each product’s detail page displays LEED-relevant information in one place:- LEED v5 Contributing Certifications — shown as tags indicating which third-party certifications qualify under BPSP
- LEED v5 Multi-Attribute Score Details — the full score breakdown, including contributing certifications and any user verification flags
- LEED Pre-checks — v4.1 pre-check status for the Material Ingredients credit, sourced from the product’s HPD data
Which Version Applies to Your Project?
LEED v4.1 registrations remain open through early 2026, with certifications accepted through 2032. Projects already registered under v4.1 do not need to transition.
