Our stringent third-party verified certification ensures homes and apartments are NGBS compliant and focuses on three attributes that are marketable to buyers and renters:

Giving Products Our Green Approval 

We not only certify green homes and developments – we also pre-approve products that help buildings earn certification.

When installed properly and in the right quantity or manner specified by Home Innovation Labs, NGBS Green Certified Products make the verification and certification process more straightforward and streamlined for builders, remodelers, and accredited green verifiers.
