Overview

Ask yourself the following questions:

  • Are you considering a career in green buildings, sustainability or energy efficiency?
  • Do you already work in the residential building trades?
  • Do you conduct home inspections?
  • Do you own a home or are you considering purchasing one?
  • Do you work in a call center or answer phones where you get questions about energy audits and/or efficiency?

If you answered "yes" to any of these questions, then basic building science knowledge is critical to your success.

What is the Building Science Principles Certificate of Knowledge?

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 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. Register here to take the 100-question online exam.
