The Building Science Aspects of Enclosure Detailing and Tie-Ins 1.0 CEU/HSW
2026-04-23 13:00 - 14:00 (America/Detroit)
The Building Science Aspects of Enclosure Detailing and Tie-Ins
The building enclosure is made up of many material types, with the predominant need of protecting the building from water infiltration. In addition, materials and tie-ins are critical to control air flow, understand thermal bridging and risks of surface condensation, and the control and flow of moisture by vapor diffusion. Sequencing of the details and tie-ins also have to consider sequencing by the trades, material compatibility, and durability, including impacts of seasonal cycling.
This talk will focus on looking at the full building science considerations of detailing, including materials that play one or more role as a control layer for heat, air and moisture. The speaker will also discuss constructability and trade sequencing considerations. These are critical things to understand in designing and configuring details, in addition to how they are presented in design drawing and shop drawing sets. This includes understanding how to integrate manufacturer standard details at interfaces such as roof to wall between roofing and wall air and water barriers and cladding.
Learning Objectives:

Gain building science knowledge in configurations of details and what elements are controlling which types of flow paths for heat, air and moisture.
Have a deeper understanding of detail sequencing considering material compatibility, as well as sequencing of the trades.
Gain knowledge in layering for durability, while also examining the build up of layers and thicknesses against construction constraints.
Be able to describe and detail layering and sequencing critical to understand in design drawings and shop drawings for building enclosure systems.

Lessons Learned: Trades that Need to Include an AVB Discussion in their Specification & Preinstallation Meetings 1.0 CEU/HSW

Lessons Learned: Trades that Need to Include an AVB Discussion in their Specification & Preinstallation Meetings
When designing a building envelope wall system, specifying, detailing, and having a pre-installation discussion about the backup substrate and façade elements, considering the water, air, vapor, and insulation systems detailing, is critical. This involves careful coordination with all façade trade elements, consideration of construction and installation tolerances, addressing the installation requirements for the substrate wall, water and air resistive barriers, insulation, and façade support system, and learning lessons from each installation. Each component must be thoroughly understood and specified within their respective specification sections to ensure comprehensive detailing. By understanding the necessary connections, material compatibility, tested systems, and limitations of construction materials, you can develop pre-installation conversation points within each building envelope and substrate meetings to proactively develop an advanced conversation about detailing, grasping the construction requirements for each component and incorporating lessons learned will enhance future detailing and specifications will significantly improve the chances of project success.
Learning Objectives:

Identify early structural design considerations needed to maintain air, vapor, water, insulation, and rainscreen systems in bid documents.
Incorporate construction tolerances when detailing substrate walls and control layers for various façade systems.
Recognize common substrate and façade wall systems and the detailing needed to coordinate drawings and specifications.
Apply lessons learned on continuity, fastening, membranes, and system tolerances to improve coordination and guide pre-installation meetings.

Sink or Swim: Effective Natatorium Envelope Design Thru Case Study 1.0 CEU/HSW
2026-05-14 13:00 - 14:00
Sink or Swim: Effective Natatorium Envelope Design Thru Case Study
Participants will develop a comprehensive understanding of the potential risks involved in designing roof and wall assemblies over pools and other corrosive environments. The session will cover effective design strategies to mitigate moisture damage by managing air, temperature, and vapor control. Key roof assembly elements—such as metal decking, fasteners, air/vapor barriers, and insulation—will be discussed in detail. Finally, these principles will be applied in a case study, covering the full project lifecycle from concept and design to application, inspections, and handover.
Learning Objectives:

Explain how moisture intrudes and affects roof/wall assemblies over pools and caustic environments.
Summarize the typical materials of construction, and advantages associated with material selection in roof and wall assemblies.
Identify the functional performance-based characteristics of a high-performance enclosure system.
Analyze various preferred natatorium roof/wall assembly details and applications in a case study.
