The ever-evolving energy codes require designers, owners, and operators to stay on top of each new iteration and understand the impact early design decisions have on all aspects of a project. This presentation provides an overview of the major envelope design drivers within the 2024 IECC and ASHRAE 90.1-2022 energy codes and how they evolved from previous iterations. It will explore major code differences, with a focus on Illinois and Chicago-specific requirements, equipping designers with the knowledge to ensure compliance and optimize building performance.
Learning Objectives:
- Evaluate energy code compliance path options and the key factors influencing their selection.
- Differentiate between 2024 IECC and ASHRAE 90.1-2022 requirements for building envelopes.
- Analyze new and updated continuous air barrier requirements.
- Understand the magnitude of the new envelope backstop requirement in ASHRAE 90.1-2022.
