2026 BES Session: The Role of Building Enclosure Commissioning in Achieving Successful Functional Performance Testing

(Kim Y.)

Course Overview
This session was originally presented at the 2026 IIBEC Building Enclosure Symposium in Indianapolis, Indiana.  This course includes the following components:

• recording of the live session
• a summative assessment consisting of 10 multiple-choice questions
• two surveys required to claim continuing education credit

Description
Functional performance testing (FPT) is a critical milestone to evaluate that a building enclosure performs as intended, yet its success depends heavily on the broader building enclosure commissioning (BECx) process that precedes it. Across recent projects, a consistent pattern has emerged: when BECx activities such as commissioning design review, development of clear performance requirements, integrated responsibilities, development of testing plan, and witnessing testing are carried out effectively, FPT produces more reliable, meaningful results. When these steps are overlooked, testing often becomes reactive, inconsistent, or inconclusive. This session discusses a practical framework for integrating BECx activities with technical guidance—such as ASTM E2813, ASTM E2947, and NIBS Guideline 3—while acknowledging the evolving expectations of programs such as LEED v5. Case examples will illustrate how systematic BECx processes help prevent common challenges—including workmanship-dependent design, unclear performance protocol, fragmented responsibilities, incomplete on-site test preparation, and exclusion of FPT witnessing from BECx scope—that frequently undermine FPT outcomes. Attendees will gain a structured understanding of how BECx supports system level performance validation through FPT, ultimately improving enclosure reliability and reducing project risk. The session is intended for commissioning providers, architects, consultants, contractors, and owners seeking to enhance the consistency and effectiveness of enclosure performance testing on their projects.
