States and local governments around the county have set ambitious climate goals that center net zero newly constructed buildings as a key component to meeting these goals. Two new models are now available to help jurisdictions achieve their climate goals: New York State Stretch Energy Code (NYStretch) and the Zero Energy Appendix in the 2021 IECC. The nearly finalized NYStretch development process has taken the recent IECC credits approach to the next level. This credit system provides flexibility and refocuses on decarbonization and resilience in buildings as the objective. The development of the NYStretch took a unique approach to cost analysis considering that electrifying now is cheaper than retrofit and future fuel projections are highly variable. The Zero Energy Homes (ZEH) Appendix to the IECC provides an off the shelf opportunity for both commercial and residential new construction. Additionally, the Inflation reduction Act will provide $670 million in aid for local adoption of the ZEH Appendix. Since the ZEH Appendix is published as part of the model IECC, it can be easily modified by adopting states and jurisdictions to better meet local climate goals, or by incentive programs or builders to meet their market demands. NBI is currently developing a guide to aid jurisdictions and program implementers in this process.

Learning Objectives: 1. Understand opportunities through the Inflation Reduction Act for states and localities to improve energy code. 2. Explain how the Zero Energy Homes Appendix can be used to meet state and local net zero energy goals. 3. Identify how credits can be used to improve flexibility for builders while focusing on decarbonization and resilience 4. Examine use of cost analysis in code and policy advancement considering future retrofits.
