Module 8: Performance path options (R405 and R406), and additional efficiency path options

This class will explain how to use the various performance path options in the IECC (Section R405 and R406) – their structure, the flexibility allowed in each, and the limitations of each.  The audience will explore various scenarios for which compliance path will best suit certain construction choices.  Finally, the class will explain the new required additional efficiency packages in R408 in the 2021 IECC.
