Other Indoor Environment Credentials

A Council-certified Indoor Environmental Remediator (CIER) corrects problems related to poor indoor air quality. For example, a CIER can perform mold remediation, asbestos removal or lead paint abatement. A CIER can deal with hazardous materials and chemicals. Finally, a CIER can handle Chinese drywall, meth lab cleanup and a host of other indoor air quality issues. A CIER has verified knowledge in a range of disciplines related to indoor air quality remediation, including asbestos, lead, hazardous materials, chemicals, mold, and meth lab cleanup. Each CIER has demonstrated at least two years experience conducting remediation projects in one or more of the following settings: Offices and commercial buildings; Industrial structures; Government facilities; Schools and public buildings; Healthcare facilities; and Residential structures.

The Indoor Air Quality Council launched the credential in 1999. In 2006, the Council discontinued membership services and focused exclusively on credential program. In 2008, the Council broadened its focus to other industries and changed its name to the American Council for Accredited Certification (ACAC). 

For healthy homes-related credentials, ACAC offers credentials in two broad categories: indoor environment and microbes. In indoor environments category, ACAC offers five credentials:

  • Two credentials for individuals who investigate indoor air problems: a Consultant and an Environmentalist. A Consultant has eight years of experience while an Environmentalist only has two years of experience.
  • Two credentials for individuals who correct problems related to poor indoor air quality: a Supervisor and a Remediator. A Supervisor has eight years of experience while a Remediator has only two years of experience.
  • Indoor Air Quality Manager credential for the individuals who establish and maintain good air quality in the built environment. The CIAQM requires two years of property management experience.

Three cautions:

  • Individuals and not firms are credentialed. Therefore, make sure the individual who is credentialed directly supervises the radon mitigation work.
  • Several states require additional certification or licensing for individuals conducting mold remediation. Check with your state.
  • If you have a complicated problem, make sure you have the more experienced Council-certified Indoor Environment Supervisor directly managing the project.
