Window(s) into the Building Enclosure as a Complete System

Windows are an integral component of the building enclosure yet are often one of the weakest links.  The complexity of building enclosure requirements and the expectations of building owners is getting more demanding.  As the separator between the interior and exterior environments, the effectiveness of the building enclosure directly impacts the durability and safety of structures and the health and well-being of the occupants.   Windows are a significant component and a potential large disruption to the continuity of the building control layers.  Do you have a grasp on the different types of window systems, how they function, and integrate into the building enclosure control layers?  In this program, we will discuss and explore the environmental forces on the building enclosure, the control layers required, and how windows integrate into the control layers to create a complete and continuous system.

Learning Objectives:

• Review and confirm understanding of the physics of moisture, air, and heat movement applied to the Building Enclosure.
• Accurately define the Building Enclosure Control Layers and explore how different window types interact with these forces.
• Examine details of different window systems, from residential-style windows to storefront and curtain wall, and how they best integrate and perform to withstand the environmental factors.
• Discuss best practices for communicating the design intent with an eye towards constructability and interaction with different claddings.
