Highlights of Published Energy Code Changes Mapping the 2021 IECC to the 2024 IECC, Commercial Requirements Only Summary This guide, relevant to the City of Austin (COA), covers what are considered, at this time, to be the major changes to the published commercial energy code (IECC). Used with the Summary of Local Amendments, it is a roadmap for the development community to better understand what to expect when the new energy codes become effective. Many more changes than are represented here have been made. Some of those not listed have been requirements in Austin for some time and are now part of the national code. Others are considered relatively insignificant or are not applicable to Austin’s climate zone. Each change, whether summarized below or not, will have differing impacts on each project so it is encouraged that practitioners become familiar with the published code. Significant Changes in the 2024 IECC The ICC Board changed the development framework of the 2024 IECC and versions going forward from a governmental consensus process to a standards development process that changed the timeline and removed governmental consensus voting from the process. The code was developed through committees and subcommittees consisting of different stakeholder categories including the public, government, manufacturers, and utilities, among others. The version of the 2024 IECC voted upon by the consensus committee was appealed by various stakeholders and went through a process that ended with final decisions by the ICC board to move certain parts of the code to optional appendices that could be adopted by local jurisdictions. The 2024 IECC includes many new components that provide pathways for local jurisdictions to meet climate goals. The Department of Energy’s analysis of the ASHRAE Standard 90.1-2022 (a compliance pathway allowed in the IECC) estimates that the average savings within our climate zone from the new code will be 8.4% by energy cost and 8.8% by carbon emissions. When savings from renewable energy systems are included, the average savings within our climate zone are 14% by energy cost and 13.8% by carbon emissions. Highlights of major changes: • Mandatory renewable energy systems • Electric vehicle charging infrastructure appendix (proposed for local adoption) • Electric-ready commercial building provisions appendix (proposed for local adoption) • Demand responsive controls appendix (proposed for local adoption) • Electrical energy storage system appendix (proposed for local adoption) Section 402: Building Thermal Envelope Requirements Additional Configuration Options for Insulation Requirements …
COA Commercial Energy Code – CURRENT AMENDMENTS June, 2024 The following is a brief summary of current amendments to the commercial energy code, recommendation for moving forward, and rationale for that recommendation. Amendments applicable to 90.1 would be adjusted to align. C201.3 Terms defined in other codes. Refers to local codes rather than model codes. C402.2.8 Insulation encapsulation requirement. Provides for more thorough insulation installation. Retain as worded Retain as worded C402.4 Roof solar reflectance and thermal emittance. Local amendment addresses repairs and high sloped, commercial roofs. Slight modifications to match model code language and renumbered to accommodate model code. Modify slightly C402.5.3 Maximum U-factor and SHGC. Local amendment considers COA design and compatibility standards. Renumbered to accommodate model code. Modify slightly C402.8 Commercial Solar Ready (Mandatory). Provides for space and infrastructure to install solar PV systems in the future. Renumbered to accommodate model code. Modify slightly C403.7.10 Ventilation filtration and filtration of return air. Provides for better air filtration as well as plenum sealing. Renumbered to accommodate model code. Modify slightly C403.15 Demand response. Now included in locally adopted appendix to model code. C404.10 Electric water heater timers. Now included in locally adopted appendix to model code.

C405.15.1 On-site renewable energy systems. Local amendment adds exceptions to projects not required to install renewable energy systems. Appendix CG – Electric Vehicle Charging Infrastructure Local adoption of model code appendix. Delete Delete Delete New New New Table CG101.2.1 Local amendment modifies the EV space percentages per occupancy type listed in the table to support local market conditions. New CG101.2.1 Quantity. Local amendment modifies the EV space percentages to accommodate long term parking garages. The percentage was adjusted to accommodate the mismatch in duration of parking in long term parking with the need and duration of EV charging in these facilities. New CG101.2.5 System and circuit capacity. Local amendment adds separate requirements for long term parking garages. CG101.2.5.4 Long term parking garages system and circuit capacity. Local amendment allows Lvl 1 charging infrastructure for long term parking garages. Appendix CH – Electric-Ready Commercial Building Provisions Local adoption of model code appendix.
