Indoor Environmental Testing and Verification Services

People search for peace of mind when it comes to health and wellness inside a building. The UL Verified Healthy Building program helps building and business owners communicate their commitment to maintaining healthy buildings and report their efforts to a growing contingent of stakeholders, including investors, tenants, government agencies and consumers.

UL Verified Healthy Building program demonstrates the truthfulness of your claims that your indoor spaces provide a healthy environment for occupants in up to five areas:

  1. Indoor air quality
  2. Water quality
  3. Building hygiene
  4. Lighting
  5. Acoustic

Earning a UL Verified Healthy Building Mark demonstrates that you as a building owner, manager or corporation are committed to a built environment that supports occupant health, well-being and comfort. UL Solutions aligns our program criteria with industry-recognized third-party organizations such as the EPA, NIOSH, WHO, CDC, ASHRAE and LEEDv4.1.

Achieve the UL Verified Healthy Building Mark

Participants have the option of achieving a tiered level approach on the key areas of building health and indoor environmental quality that impact them the most:

Verified Healthy Building for Indoor Air

  • Building spaces are evaluated against rigorous methodologies to indoor air quality (IAQ) and have policies and plans for the continual advancement of IAQ. 
  • HVAC system inspections verify preventative maintenance and focus on ventilation, filtration and hygiene to help ensure excellent indoor air quality into the future.

Verified Healthy Building for Indoor Air and Water

  • Along with the IAQ methodologies above, building spaces are assessed to establish water quality for both human consumption and the prevention of waterborne pathogens.

Verified Healthy Building for Indoor Environment: Air, Water, Hygiene, Light and Acoustics

  • Building spaces demonstrate performance in all five assessment areas: IAQ, water quality, building hygiene, lighting and acoustics. This includes comprehensive checks for building cleanliness and ensuring that light fixtures and acoustics support the well-being of building occupants. 
  • Policies and plans are in place for the continual advancement of indoor environmental quality (IEQ).

From air quality to more comprehensive Verification, UL Solutions experts can help you feel confident with your space so you can pass this confidence to occupants.

There are currently over 600 green building rating systems in use globally. American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) released their annual certification and rating systems comparison, and ASHRAE recognized the UL Verified Healthy Building Mark as one of the 17 rating systems with the most relevance to ASHRAE’s review criteria.
