2026 BES Session: Bridging the Gap: ASHRAE90.1-2022 Thermal Bridging Derating Compliance (Wagner J.)

2026 BES Session: Bridging the Gap: ASHRAE90.1-2022 Thermal Bridging Derating Compliance

(Wagner J.)

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

ASHRAE 90.1-2022 introduces the most consequential changes to building enclosure performance requirements in more than a decade. The expanded mandate of factoring thermal bridging risks alongside whole building air leakage testing pathways represents a fundamental shift toward quantifiable, enclosure driven energy compliance down to the architectural detail.  Unlike voluntary programs such as Passive House or ordinances like NYCECC or 2017 DCECC, which address thermal‑bridge derating at the municipal level, the new ASHRAE90.1-2022 framework embeds thermal performance metrics directly into the enforceable code structure at the state level, nationwide. This elevates high performance enclosure objectives from a design aspiration to a regulated requirement affecting detailing, specification, and energy modeling workflows. For practitioners, the transition presents both challenges—ranging from coordination of thermal break strategies in conventional enclosure assemblies, to the integration of derating assessment into project design and delivery schedules—and significant opportunities to improve enclosure reliability and enclosure thermal integrity. This presentation overviews technical implications of 90.1 2022 for building enclosure consultants, architects, engineers, and commissioning providers, clarifies compliance pathways, and proposes practical strategies for embedding thermal bridging evaluation and enclosure testing into standard design and construction project delivery.
