In this presentation, we’ll explore the basics of building science to establish a foundation to discuss the risks and best practices for the design and construction phases of a building’s life cycle. We’ll review the basics for envelope control layers to establish a common language for our discussions of the building envelope. Then we’ll discuss the importance of the building envelope regarding the performance of a building and the risks associated if the envelope fails to perform. There are best practices during design and construction that will help optimize the envelope’s performance and the satisfaction of all involved parties.

Learning Objectives:

1.  Increase your understanding of the building envelope.
2.  Note critical attributes of the building envelope.
3. Decipher risks associated with the building envelope.
4.  Study the prevention of issues with the building envelope including design reviews, submittal reviews, mockups and/or first installations, construction observations, construction clarifications & questions, and quality control testing.
