The NAHB Research Center, an accredited third-party testing and certification
agency, runs the
National Green Building Certification Program. At the program’s core is
Green Building Standard™, the only consensus-based, ANSI-approved
national green standard for residential construction. The Research Center
trains and accredits green verifiers across the country to conduct verification
on new construction, remodeling projects, and residential land developments

"double-dipping" on points across categories, as well as a number of mandatory

Construction spreadsheet is an alternative scoring option for those more

The NAHB Research Center trains, tests, and accredits individuals across the
country to perform verification services for the certification program, and all
