Cracking Code: Back to the Future - 2018 IBC Updates

This is the fourth session in the 2020 Cracking Code series presented by AIA Seattle’s Codes Committee. 

The 2018 International Building Code comes into effect in Washington early next year. This seminar reviews important changes in code requirements that affect projects in the state permitted after the effective date of code adoption. New requirements address important topics such as rooftop occupancy, energy systems such as photovoltaic arrays and battery energy storage systems, changes in use group definitions, new occupant load factor for business uses, and new limits on the use of fire walls. A portion of the second day will be spent covering key code requirements for design of occupied roofs. We will highlight design challenges in meeting code provisions for occupied roofs and will explore potential code-based solutions.
