Building Science Basics (BSB) is the introduction to the house as a system with respect to energy efficiency. This system is made up of the building envelope, surrounding environment, and occupants.

How much do you know about Building Science right now?

Upon completion you will know how these components are affected by the interactions of heat, air and moisture flow in a house, and how those interactions impact indoor air quality and the need for ventilation.

The course has three modules. You can download the course outline here. Each module has a quiz at the end. You need at least a 70% grade in the quiz at the end of each module to proceed to the next (there is no limit on quiz attempts).

Once you pass the third module you take the final test, which you may only take once.

A grade of at least 70% earns you a Blue House Energy Certificate of Achievement.

Successful completion of BSB (US) will earn you 4.5 BPI Continuing Education Units. Find out how to claim your CEUs here.

If you wish to earn CEUs for other (non-BPI) certification organizations in the US, purchase Building Science Basics through GreenHome Institute.
