Certified Indoor Environmentalist (CIE) (SUS-CIE01)


Course Description

Do you work in the field of indoor air quality (IAQ)? The Council- certified Indoor Environmentalist (CIE) is the most popular indoor air quality certification. If you investigate air quality problems such as mold, VOCs, allergens, dampness, poor ventilation and sick building syndrome, the CIE is great certification to substantiate your knowledge and experience. The certification is designed for environmental consultants, HVAC professionals, property inspectors, industrial hygienists, restoration contractors and others working in fields related to indoor air quality.

We're all concerned about the air quality in their workplace, home or school. The Certified Indoor Environmentalist training program will help you determine if these clients do, in fact, have a problem. You'll learn the practical steps you should always follow in an indoor environmental assessment, how to take samples, and how to resolve common IAQ problems. You'll learn about HVAC, building science, and the major contaminants, including their health effects.

Not only does our certified environmentalist training program teach you practical skills to assess indoor environments, it also prepares you for the CIE and CIEC certifications by the American Council for Accredited Certification (ACAC). All the pertinent topics covered on the certification exams, including a 100-question practice examination, are included in this program to prepare you for certification.

The CIE certification will demonstrate to your clients that you:
• Excel at diagnosing, resolving and preventing common IAQ problems
• Understand how a building’s HVAC system can control (and cause) IAQ problems
• Incorporate the full spectrum of contaminants into your IAQ assessments, which may include mold, bacteria, VOCs, carbon monoxide, radon, triggers to asthma & allergies and more
• Apply current industry guidelines
• Comprehend the fundamentals of building science
• Use IAQ instruments and equipment to measure contaminants

If you'd like to become an indoor air quality or green building consultant, this program is for you. While the program is designed for students without any experience, you may more easily comprehend certain sections of the program if you have a background in HVAC, home inspection, construction, or healthcare. There are no prerequisites to taking the CIE Program.


Just attending our CIE preparatory course does not make you certified, although you will receive a certificate of completion from the Indoor Air Quality Association. To actually become certified as a CIE, you must first meet certain experience requirements and pass an examination offered through the independent certifying body, American Council for Accredited Certification (ACAC).

Before you are allowed to take the ACAC’s CIE examination, you must first fill out an application that describes your experience in the field of indoor air quality. If you are new to the field and don’t have any experience, consider taking the CRIE: Council- Certified Residential Indoor Environmentalist. CIE applicants must possess one of the following combinations of two (2) years education and relevant field experience:
• No degree, with at least two (2) years of documented field experience conducting indoor air quality investigations. (High school diploma or GED required.)
• A 2-year post-secondary degree or its equivalent (15 credit hours) in engineering, science, architecture, industrial hygiene or related field of science with a minimum of one (1) year of documented field experience conducting indoor air quality investigations.




Ian Cull, PE, CIEC, CMC, CIAQP, is the president of Indoor Sciences and was elected in 2006 and 2009 by the membership of the Indoor Air Quality Association (IAQA) to serve on its board of directors for three-year terms.
