BPI Building Science Principles (BSP) Certificate Prep

This is a great chance to learn building science from one of the top instructors in the world. Brynn has been teaching this course in person for years – now he’s ready to answer your questions and help you earn your BSP Certificate.

This course is a prerequisite to the BAT technician certification exam, which is a prerequisite to the Building Analysis Professional Exam.

Earning the Building Science Principles (BSP) Certificate of Knowledge is your first step into the world of energy-efficient home performance. You will learn some of the widely-used industry terminology related to building science. Building science demonstrates how various components of a home interact to affect the home’s overall performance. Understanding the relationships between the building envelope, heating, A/C, insulation, mechanical ventilation, lighting, appliances, and other systems of the home will enable you to assist yourself and others. Learn how these systems affect the comfort, health, and safety of occupants and the durability of the home. Discover why improving the energy efficiency of the home should be the first step toward solar, geothermal, or other renewable energy improvements.

The second edition of the BSP guide features an extended renewables section and an entire chapter dedicated to the U.S. DOE Home Energy Score. The guide and the exam are available in English or in Spanish, based on the user’s preference.

The BSP Certificate of Knowledge can be earned by studying the guide and then challenging the BSP online exam from your computer. The BSP exam is a 100-question multiple-choice exam with a passing score of 70%. Once you successfully complete the exam, you can print your personalized BSP certificate from a computer connected to a working printer.
