This national certification is the first BPI standard for the air sealing and insulation industry within efficiency and weatherization. This certification is designed for entry level efficiency and weatherization contractors to develop their skills to properly air seal and insulate residential homes or small commercial buildings. How to assess problems and fix them using the correct materials is the focus of the certification. Students don’t need to have their Building Analyst Certification to attend this program but it will be an advantage for those that do.
