New Jersey uses the 2021 IECC, and a lot of jurisdictions here enforce a stretch code on top of it. That pushes the efficiency bar higher than the baseline standard. For permitted window replacement work, confirm with your contractor what the local building department actually requires before anything gets ordered.
