Quality Control Inspector lays the groundwork for individuals interested in understanding and expanding their knowledge of monitoring and inspecting weatherized units. Students will thoroughly cover sessions on regulations and standards, desk monitoring, tools of the trade, building assessment, interpretation of infrared imagery, in-progress monitoring, and what to include in a report. The course follows the Department for Energy’s standardized curriculum for Quality Control Inspector and has been modified to align with the NREL Job Task Analysis for Quality Control Inspector. The structure of the course includes lecture, dialogue and practical experience through hands-on skill sets.

Additionally, this course can serve as a review to prepare participants for the Building Performance Institute’s (BPI) written and field exam for certification as a Quality Control Inspector.
