Assist states to adopt enhancements to the residential chapter of the iecc, putting these states on a pathway to net-zero energy and emissions for new homes

Specific objectives include: (1) three sets of amendments to the iecc developed for use by states and other jurisdictions (zero ready, near zero, and zero); (2) supporting materials and analyses for these three code packages prepared to assist jurisdictions with adoption and implementation of the amendments; (3) technical assistance (TA) provided to at least 18 states and jurisdictions to assist with adoption and implementation of the amendments, and also to utilities in coalition states on programs promoting higher amendment tiers; (4) at least nine states or jurisdictions adopt the amendments, at least in part; (5) exploring a path for federal agencies to adopt our zero ready tier as a possible requirement for new homes backed by federal mortgages; (6) reviewing and revising the amendments and supporting materials based on initial state experience with the amendments and feedback from affordable housing and equity groups; (7) amendments proposed to the iecc as technical appendices to the 2030 iecc; (8) instituting a plan for amendment package sustainability beyond the funding period.
