Updated IC3 Calculator for Single-Family Projects 
Austin Energy Green Building has partnered with Energy Systems Laboratory at Texas A&M to include updates to the 2015 IECC IC3 Calculator for Austin. When creating or editing a project, you will now see an option for 2015 IECC AE REVISED. To ensure no data loss for existing projects the 2015 IECC AE version still exists. Updates include

• adding option for a 4^th floor
• updating efficiency specs for heat pump systems and water heaters
• incorporating UEF metric for water heaters
• updating minimum ceiling insulation R-values for better flexibility in the performance path

If none of these changes apply to you, keep using the 2015 IECC AE version. Otherwise, give the updated version a try! https://ic3.tamu.edu/

All changes will get rolled up into a 2021 IECC AE calculator once developed.
