What Does an Accredited Consultant Mean for Me? Pt 2 

The accreditations your building enclosure consultant has can determine your project outcome. Picking up where we left off in our last blog, REWO and Certified Level 1 Thermography are among the most respected accreditation titles. 
What is REWO? 
A Registered Exterior Wall Observer (REWO) is an exterior wall accreditation from IIBEC. Similar to an RRO, a REWO is an on-site monitor during exterior wall work. The observer’s knowledge and documentation ensure that the work is installed as designed. Working directly with the design team, they check the quality of all materials and supplies used on-site.

Applicants must complete the examination, agree to the IIBEC Code of Ethics, and have experience in one of the following areas: 

  • QA inspector/consultant in exterior walls for two cumulative years
  • Exterior wall construction for two cumulative years
  • Exterior wall manufacturer’s technical or sales representative for four years


  • 12 hours of continuing education earned
  • A minimum of three building enclosure-related seminars
  • Five references

In order to maintain this accreditation, an annual renewal fee and ten building envelope-related continuing educational hours earned each year are required. 
What is Certified Level 1 Thermography? 
Certified Level 1 Thermography is a training implemented for the proper use and knowledge of infrared technology. This certification ensures one can identify and document thermal patterns caused by moisture intrusion, improper workmanship, etc. 
In order to receive this certification, applicants must complete the course and pass the examination.

Why Have Accreditations? 
Why receive further education? Why benefit from extensive training? Having detailed knowledge from industry experts allows observers to fully understand what they are evaluating and not be surprised by different scenarios. Accreditations are widely acknowledged by clients. When deciding who is right for the job, your chances increase when you can prove you have gained recognition for your knowledge in the field. The many requirements to receive the accreditations on top of the examination and continuing education makes the decision quite obvious.
