Building science concerns the flow of energy and moisture through buildings. In this lesson, SIPschool founder Al Cobb examines the building science behind SIPs.

Learning Objectives:

- Explain what building science is and summarize what is meant by the term “house as a system.”
- Summarize how and why energy, moisture and vapor move through a structure and why it is important to control this flow
- Detail roof and wall venting in a SIPs building, and explain where, why and how we should do it
- Define dew point and understand how condensation can form in buildings
- Identify the key areas in a SIPs building where heat loss and condensation potential must be controlled
