It sets energy-efficiency standards that every new commercial building must meet before it can be approved. The core rules are national, but each state adds its own twist, and missing those local variations causes costly delays.  Here is how Section J works, and where the states differ. What Is Section J? Section J is the energy efficiency chapter of the National Construction Code. It applies to commercial building classes 3 and 5 through 9, covering offices, hotels, shops, warehouses, schools, and hospitals. The rules were tightened significantly in NCC 2022.
