NBS compatibility

National Building Specification (NBS) is the industry standard specification library.

NGS’s Green Building Specification (GBS) is designed to complement NBS.

NGS's GBS clauses are written specifically to address issues of environmental sustainability.

NBS adopts and develops the Construction Project Information Committee’s (CPIC) classification system Common Arrangement of Work Sections (CAWS) 1998 edition.

GBS adopts and develops the CPIC and NBS versions of CAWS to enable integration into NBS-based specifications.

GBS adopts NBS clause numbering to provide for easy clause assimilation.
