Catch Andrea Love, PAYETTE’s Director of Building Science, at the Quebec Chapter of the Canada Green Building Council for a LEEDv4 conference.
The LEED Matchup: A Case Study Comparing LEED 2009 and LEED v4
How does LEED version 4 differ from LEED version 3? This presentation will be a case study of one project’s experience looking and comparing these two versions. It will provide an overview of critical changes and differences observed for the project between v3 and v4, as well as a summary of the benefits and disadvantages. This presentation will be helpful for those familiar with LEEDv3, and interested in understanding the critical differences under v4. With the concurrent overlap of LEEDv3 and LEEDv4 for the next year, this analysis may assist project teams currently deciding between the versions to pursue.
We are honored to share PAYETTE has received two 2026 Green Good Design Awards from The European Centre for Architecture Art Design and Urban Studies—Land’s Sake Farm and The Ragon Institute of Mass General, MIT, and Harvard.
