Model energy efficiency codes (ASHRAE 90.1 & International Energy Efficiency Code (IECC)) are under continuous maintenance and publish an updated edition every three years. The energy code, however, does not become a regulation until it is adopted by a state or jurisdiction. Therefore the timeline for updating varies by individual jurisdiction. Further, the adopted code must than be enforced by local authorities. This presentation will discuss the development of air leakage requirements in the model energy codes for commercial buildings. It will then describe the status of adoption of model codes by the states. Finally, the implications for enforcement through whole building airtightness testing of the adopted code will be discussed.

Designing Roofs to Withstand Nature’s Worst
Key Considerations to Help Your Roof Withstand the Next Big One

As the saying goes, when nature is at its worst, buildings need to be at their best. Roofs at their base level are designed to keep weather out. As weather gets more extreme, roofs are being asked to withstand even more: manage more water, defend against larger hail and stay on during high winds.

During this webinar, you will learn about the new wind requirements in ASCE 2022, best practices for designing for very severe hail, and ways to manage water from large rain events.
