The UL Indoor Air Quality Certification Program is the world’s first comprehensive indoor air quality (IAQ) certification and preventative maintenance program. It addresses moisture, airborne volatile organic compounds (VOCs), airborne particulate matter (PM), integrated pest management (IPM) and other aspects of indoor air quality and provides the Certification Holder with a third-party UL/GREENGUARD Certification Mark to communicate the achievement to their customers and stakeholders.

The purpose of this program is to identify and prevent moisture issues that can lead to mold growth, reduce exposure to harmful VOCs, fine PM (PM2.5) and other indoor air quality issues during building operations, highlight the impacts of multiple related or interdependent systems, and give facility managers, maintenance staff, occupants and residents the tools to avoid costly indoor air quality problems and maintain a healthy building going forward. In addition, the program provides reasonable measures to detect recognized and common sources of indoor air quality problems where they occur.

Residential IAQ (GREENGUARD for Homes) UL 3036

  • For multifamily and modular homes as well as site built houses that are essentially identical design and specify the same low-emitting materials
  • Applies to tested models that are demonstrated compliant by inspection and testing
  • Applies to units at the time of occupancy
  • Annual re-certification of the model after successful audit and retesting

Benefits include:

  • Confidence in designs of components and selection of materials
  • Knowledge that the ventilation system design was reviewed and performance assessed
  • Occupants are more informed on effective management of IAQ / IPM / moisture

Children, the elderly and some other groups are more sensitive to pollution than healthy adults and tend to spend more time in the residence than working age adults. All seven of the healthy homes principles noted by the National Center for Healthy Homes are recognized by components of the ResIAQ certification. Only the occupants can keep a home safe and healthy, but that is made easy if the residence is designed and built to promote good conditions.

Building IAQ UL 2891

  • For commercial and institutional buildings and for buildings in the hospitality industry.
  • Applies to specific buildings or portions of buildings that are demonstrated compliant by inspection and testing
  • Applies to assessed buildings when occupied
  • Two certification extensions permitted with successful audits – Renewable after 39 months

Benefits include:

  • Reduction in maintenance costs through early detection of indoor air quality issues. Mold and moisture remediation costs over 100 times more on average than a prevention program (US DOE “Moisture Management Market Opportunities Situation Analysis,” 2005).
  • Reduction in complaints and potential for downtime through avoidance of indoor air quality problems such as odors and remediation efforts.
  • Enhanced quality control of contractors and third-party vendors.
  • Differentiation, brand enhancement, and demonstration of market leadership.
  • Detailed indoor air quality reports and monitoring data that streamline documentation and effort required for certification to green building programs such as LEED® and Green Globes.
  • Occupant engagement on their role in promoting IAQ

Reduce absenteeism and increased productivity through healthier indoor environments. A study conducted by West Bend Mutual Insurance Company found an increase in employee productivity of up to 8% by creating and maintaining good indoor environmental quality in their facilities. As a result, the financial impact of creating a healthier indoor environment is estimated to be more than fifty-times the cost savings from energy efficiency measures required for LEED Silver Construction.
