Provide science-driven healthier spaces for tenants and occupants

The UL Verified Healthy Building program offers the real estate industry an independent source of verification  from a respected safety science leader. This program leverages 40 years of indoor environment inspections to develop a quantitative review process driven by: 

  • Building metrics discerned through performance testing
  • Comprehensive on-site visual inspections
  • Verification of the implementation of policies

The program features three tiers that examine different factors against accepted science-centric standards.

UL Solutions aligns our program criteria with industry-recognized third-party organizations such as the EPA, NIOSH, WHO, CDC, ASHRAE and LEEDv4.1.
