What LEED v5 BD+C Means for Enclosures  

LEED v5 BD+C introduces significant changes to the rating systems' credit structure, its energy performance requirements, and building enclosure requirements (BECs) that will affect project designs and budgets. This webinar offers a brief orientation to what is new in LEED v5 BD+C, then focuses on two areas with direct cost and scheduling implications: the shift from ASHRAE 90.1-2010 (LEED v4's reference standard) to ASHRAE 90.1-2019 (LEED v5's reference standard), and what that more stringent standard could mean for initial project budgets and lifecycle costs compared to LEED v4.

The session then turns to Building Enclosure Commissioning (BECx), covering the prerequisite scope and the credit pathway for teams pursuing additional points. Attendees will leave with a practical understanding of how these changes affect project budgeting, team coordination, and enclosure quality assurance on their next LEED v5 BD+C project.
