Above-Grade to Below-Grade Continuity: Applications, Performance, and Details
In the world of high-performance building enclosures, the transition from above-grade wall systems to below-grade waterproofing continuity requires more than just high-quality products; it demands a sophisticated understanding of how systems interact across disparate assemblies. This technical webinar dives deep into the “gap” that often exists between the architectural facade and the foundation. We will explore the fundamental criteria for whole-building airtightness and define the specific challenges of various enclosure types, occupancies, and design criteria. Participants will gain a comprehensive overview of modern waterproofing technologies, comparing liquid-applied, self-adhered, and sheet membranes. The session will contrast vertical and horizontal applications, as well as the unique detailing requirements for pre-applied vs. post-applied systems. Through a series of detailed transition scenarios, including above-grade walls to below-grade footings and horizontal plaza waterproofing. Beyond the technical drawings, we will discuss the “human” side of building science: specifying for success. We will cover how to eliminate scope gaps and foster essential coordination between designers, manufacturers, and contractors to ensure a seamless, high-performance building enclosure.
Learning Objectives:

Analyze the critical role of whole-building enclosure continuity for building performance.
Identify appropriate waterproofing technologies for various above- and below-grade scenarios.

Warmer, Wetter and Windier: Future Proofing Your Building Enclosure for Extreme Weather 1.0 CEU/HSW
2026-04-02 13:00 - 14:00
Warmer, Wetter and Windier: Future Proofing Your Building Enclosure for Extreme Weather
Building enclosure design has always been driven in part by the ability to moderate the outdoor environmental conditions and maintain an operational indoor environment. The demand on building enclosures is evolving rapidly as changing climatic conditions require the design to mitigate more intense weather events. Climate variables such as increased rainfall, rising or falling temperatures, more extreme winds, or more frequent intense storms can impact building enclosure design in different ways and require specific design strategies to reliably perform during extreme weather. Incorporating resiliency measures can help ensure buildings maintain their functional use and prevent losses during utility outages.
This presentation will begin with an overview of climate forecasting and adapting the project requirements to the future needs of various building types. The discussion will focus on the implementation of specific construction approaches from schematic design through construction and integration. Each approach will be considered with respect to reducing operational energy use through strategies such as increased insulation, increased air tightness, and optimal daylight design. We will investigate enclosure assemblies that may have performed adequately in the past but in a changing climate no longer provide adequate control. We will investigate building enclosure assembly selection to prioritize increased resiliency and durability, including redundant passive systems. Reuse and adaptation of the existing building stock will be investigated. Finally, the design approach must consider the ability to maintain comfortable or operable interior conditions during catastrophic events.
Learning Objectives:

Identify changing climatic conditions that influence enclosure design such as increased wetting, changing vapor diffusion, shifting heating/cooling loads, and increased wind loads.
Understand how a changing climate can influence criteria for the overall building design such as wind funneling, pedestrian comfort, snow drifting, stack effect, flooding, and ice/snow accumulation.
Prioritize enclosure design strategies for durability, reduced maintenance, reuse, and resiliency
Investigate how previously successful enclosure assemblies may no longer perform adequately due to climate change.

Lessons Learned: Trades that Need to Include an AVB Discussion in their Specification & Preinstallation Meetings 1.0 CEU/HSW
2026-04-30 13:00 - 14:00
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.

Megapanel Mania: Prefabricated Exterior Wall Assemblies 1.0 CEU/HSW
2026-05-21 13:00 - 14:00
Prefabrication of exterior wall systems and assemblies is a growing trend in the construction industry. There are many terms used to describe this process (panelized, modularized, unitized, etc.) and the definition and scope of prefabrication can be as unique as the project itself. For many projects, the exterior walls are anticipated to be panelized or unitized from the start as is often the case with precast concrete panels and aluminum-frame curtain wall systems. However, sometimes modularization is proposed by the construction team after design is complete as a means of expediting the schedule, addressing site access constraints, and/or lowering project costs. The presenters will describe different types of panelized exterior wall assemblies and will present a case study regarding a 10-story, 700,000 square foot healthcare facility that utilized megapanel exterior wall construction. The change to a panelized approach occurred after the design was complete, resulting in challenges associated with continuity of air, water, and thermal control layers, particularly at the interface conditions. Perspectives and lessons learned from the building enclosure commissioning provider (BECxP) and contractor’s building enclosure consultant for this project will also be offered.
Learning Objectives:

Understand various exterior wall prefabrication techniques and several advantages and drawbacks of panelized construction.
Demonstrate an understanding of building science and the impacts of megapanel joinery and transitions with respect to building enclosure performance and continuity of air, water, thermal, and vapor control layers.
Appreciate challenges associated with integrating exterior wall and roof construction in panelized assemblies.
Describe building enclosure quality assurance and quality control efforts that can be performed in the prefabrication facility, for mock-ups, and at the construction site.

Buildings Move, Buildings Leak: Revisiting the Critical Link Between Engineering Mechanics and Enclosure Performance 1.0 CEU/HSW
2026-05-28 13:00 - 14:00
“Systems thinking” is a term that is discussed at times in Building Science. But what if systems thinking asks us to consider more factors in the long term viability of enclosure integrity? While the relationship between structural movement and a structure’s usefulness to its intended purpose has been well developed throughout the history of design and construction, that understanding has not always translated well into satisfactory enclosure performance.
Drawing on experiences in post-construction forensic investigations, troubleshooting during construction, and efforts to influence design detailing, this presentation will discuss key factors in applying engineering mechanics for the benefit (or detriment) of enclosure performance. Specific aspects to be shared will include the cross-party dynamics in design and construction that give rise to current challenges, case studies of failures as a result of insufficient consideration, and areas for improvement across the design and construction industry.
Learning Objectives:

Participants will develop a better understanding of the relationship between movement of materials and enclosure integrity
Participants will gain perspective around what should be considered minimum baseline requirements for performance specifications particular to accommodating movement
Participants will learn about case studies where enclosure systems were compromised or even failed as a result of limited awareness around building movement
Participants will see examples that reinforce the connection between effective project collaboration and desired performance of the enclosure
