Americans spend 90% of their time inside buildings which means the designers need to know how their envelope systems work to control energy & moisture. Several factors influence the actual energy performance of a building envelope so will use this time to discuss not only precast envelope systems but various wall systems both as rain barriers and rain screens.

This 2016 update of the Designer's Notebook #15 offers 1 HSW/LU (or 1 PDH).
After reading this article, readers will be able to:

1. Discover how to control energy and manage moisture in an envelope system.
2. Understand the various codes that are applicable for wall systems.
3. Develop a deeper understanding of the insulation systems for walls and R-values and U-factors.
4. How to create an air barrier system within one building envelope system.
