The first model code focused on new and existing commercial buildings addressing affordable green building design and performance. The IgCC provides the building industry with language that both broadens and strengthens building codes in a way that will accelerate the construction of high performance green buildings.
It provides a vehicle for jurisdictions to regulate green for the design and performance of new and renovated buildings in a manner that is integrated with existing codes, allowing buildings to reap the rewards of improved design and construction practices. Includes ANSI/ASHRAE/USGBC/IES Standard 189.1-2014 for the Design of High Performance Green Buildings Except Low-Rise Residential Buildings as an alternative path of compliance.
