Energy efficiency standards for building construction; extend date of repeal.

SB 2308 extends the expiration date of Mississippi's energy efficiency standards for building construction, which were originally set to end on July 1, 2029. These standards require new commercial and public buildings (including offices, schools, retail stores, and hospitals) to meet specific energy-saving design practices based on national guidelines. The bill does not alter the existing requirements but ensures they remain enforceable beyond 2029. This affects building developers, contractors, and local governments responsible for implementing and enforcing the codes.
