Retrofit Installer Technician is based on portions of the National Renewable Energy Laboratory/U.S. Department of Energy Job Task Analysis (JTA)1 for Weatherization Crew Leader. Students taking this course will gain a basic understanding of building science and the house as a system. Students will receive a sample work-scope and follow it from conception to completion using the house as a system approach. The curriculum is suitable for weatherization crews, retrofit workers, and those seeking a better understanding of weatherization and basic building science. This course is designed to prepare qualified students to take the BPI Home Energy Professional Retrofit Installer Technician certification exam. The majority of the class is spent in our state-of-the-art training labs, practicing whole-house weatherization techniques. Air sealing and insulation installation are only a small portion of the skills that students will learn. Students will get feedback about learning progress by taking online quizzes via our Learning Management System (LMS) throughout the course. Students will take a written test, also delivered via our LMS, and a hands-on test of weatherization skills that were practiced during the course. Upon successful completion of the tests, each student will receive a certificate of completion.
