Effects of Interior Air Management Systems on Exterior Enclosure Performance (Hughes J.) Course Overview This session was originally presented at the 2026 IIBEC Convention & Trade Show in Sacramento, CA.  This course includes the following required components. recording of the live session summative assessment consisting of 10 multiple-choice questions course evaluation survey Description A midrise judicial building developed to replace federal and local court systems was completed in 2021; however, difficulties with closing out the project resulted in shortcuts taken by a bond company that took control over the work, culminating with an improper phased test and balance of the building air management system that was performed floor by floor and not as a total building.  By not considering the building as a whole, this phased approach to the HVAC commissioning and test and balance did not identify a potential for high negative interior air pressure resulting from unbalanced supply and return to the air handler units for each floor.  Although the building enclosure was commissioned with satisfactory completion of all air/moisture barrier systems, two years following occupancy the building experienced water intrusion on every floor during multiple rainstorm events.  Storm water migrated to the building’s interior critical occupancy spaces during each event.  Initially, it was assumed to be a cladding and glazing installation failure, even though the construction phase enclosure commissioning integrity tests were successful.  After a year of diagnostic evaluations performed on the enclosure systems, a full diagnostic/forensic mode-of-failure analysis that included the buildings heating and cooling design finally identified the primary cause of water intrusion.  The results of that mode of failure or root cause investigation identified significant negative interior pressure throughout the building.  This interior negative pressure combined with exterior positive wind pressure during certain rain storm events that resulted with a large pressure differential exceeding the design tested pressure of the robust curtainwall glazing system under normal use.  This presentation focuses on the physical effect of air pressure differential on a building enclosure resulting in moisture intrusion despite proper installation of exterior cladding. The interior air management of a building affects performance of the enclosure roofing and cladding systems and must be considered as part of a leak/failure analysis protocol.  Speaker/Author Joseph Hughes, AIA, RA   Course Access Courses are accessible in LearnUpon for one year from the date of purchase.

The Not So Perfect Wall (Gentry T.) Course Overview This session was originally presented at the 2026 IIBEC Convention & Trade Show in Sacramento, CA.  This course includes the following required components. recording of the live session summative assessment consisting of 10 multiple-choice questions course evaluation survey Description Nearly two decades ago, Joseph Lstiburek delved into “The Perfect Wall” with his ASHRAE Journal article. It has served as a springboard for seeking greater insight into the relationships between, and the methods used to manage, the four building enclosure phenomena of liquid water intrusion, air infiltration and exfiltration, water vapor migration, and heat transfer. The goal of this presentation is to provide additional insight for managing the four phenomena by focusing on: 1) the constructability of commonly used subassemblies to manage these phenomena; and, 2) the integration of the subassemblies within the whole of the building enclosure; i.e., this presentation seeks to provide additional insight by focusing on “real world” conditions. To reach this goal, common constructability related causes for the uncontrolled intrusion of liquid water, the infiltration and exfiltration of air, the migration of water vapor, and the transfer of heat are identified and then evaluated under transient environmental conditions—as opposed to evaluations under steady state environmental conditions—to better understand the consequences of allowing the phenomena to be uncontrolled.

Proactive Strategies for Managing Building Enclosure Penetrations: Improving Performance and Reducing Risk (Krumpos D., Pettoni S.) Course Overview This session was originally presented at the 2026 IIBEC Convention & Trade Show in Sacramento, CA.  This course includes the following required components. recording of the live session summative assessment consisting of 10 multiple-choice questions course evaluation survey Description Building enclosure penetrations—such as those required for mechanical, electrical, and plumbing (MEP) systems—are critical junctures that can significantly impact a structure’s long-term performance. When not properly addressed during design and construction, these details can lead to water intrusion, air leakage, thermal bridging, and maintenance issues. As building enclosure performance expectations increase, in conjunction with owner expectations of durability and resilience, adopting a proactive approach to managing penetrations is essential.  This session examines the risks associated with poorly coordinated or improperly executed penetrations, drawing on case studies where missed opportunities in early specification decisions—or late-stage improvisation—led to enclosure failures, rework, and performance risk. Attendees will gain insight into best practices for managing penetrations from the design through installation. Participants will  be provided with practical tools for addressing penetrations at every stage—whether drafting details, reviewing submittals, or observing field installation—based on real-world challenges faced by architects, engineers, and building enclosure consultants. Managing penetration effectively from the design through construction is critical to achieving resilient, high-performing enclosures. This session equips attendees with the strategies and context needed to make building enclosure  penetrations a maintainable strength, not a continuing vulnerability. Authors/Speakers Darbi Krumpos, CDT, BECxP, CxA+BE Principal Socotec Sheri Pettoni Marketing & Business Development Lead RPH Course Access Courses are accessible in LearnUpon for one year from the date of purchase. Course Recommended Prerequisite(s) Learners should have experience working with building enclosure systems and construction detailing, particularly as it relates to the integration of mechanical, electrical, and plumbing (MEP) penetrations. Familiarity with air and water barrier continuity, thermal bridging concerns, and relevant penetration codes and standards will enhance the session’s applicability.

Hail Impact Testing of Modified Bitumen Roof Membranes (Mase H., Koziol R.) Course Overview This session was originally presented at the 2026 IIBEC Convention & Trade Show in Sacramento, CA.  This course includes the following required components. recording of the live session summative assessment consisting of 10 multiple-choice questions course evaluation survey Description Wiss, Janney, Elstner Associates, Inc. (WJE) and the Midwest Roofing Contractors Association (MRCA) have a history of collaborating to develop research and testing programs that focus on expanding industry knowledge of commonly used roofing materials. One such focus was on granule-surfaced, modified bitumen roofing membranes. WJE, in collaboration with the MRCA Technical & Research Committee, developed a testing program to evaluate the influence of hail impact on granule-surfaced modified bitumen roof membranes installed in low-slope roof assemblies. The objective was to determine the extent of damage to various aged membranes from a single manufacturer through physical testing and laboratory review and analysis. Testing was conducted in accordance with ASTM D3746, Standard Test Method for Impact Resistance of Bituminous Roofing Systems. Samples were impacted by a 5-pound, 2-inch diameter steel missile released from a height of 53 inches. Sample weights, granule counts, and exposed bitumen measurements were taken both before and after the impact. Desaturation of the membrane samples was conducted to remove the bitumen and make visual observations of the reinforcement. Additionally, microscopy of the impacted cross sections was performed. This presentation will describe the testing program procedures and corresponding results. Those who are interested in hail assessment would benefit from this presentation.

Soffit Detailing Strategies for Performance and Durability in Modern Building Enclosures (Wartman E., Li X.) Course Overview This session was originally presented at the 2026 IIBEC Convention & Trade Show in Sacramento, CA.  This course includes the following required components. recording of the live session summative assessment consisting of 10 multiple-choice questions course evaluation survey Description Soffits are often overlooked in the design and construction of the building enclosure, yet small missteps can significantly impact thermal performance and air and moisture management. This presentation explores common failures and best practices in soffit detailing, grounded in field investigations and building science analysis. Using WUFI hygrothermal modeling and THERM thermal bridging analysis, we will examine how soffit design affects drying potential, condensation risk, and overall enclosure performance—particularly in climate zones where venting, drainage, and thermal continuity must be carefully balanced. Through case studies and simulation results, we’ll demonstrate how improper soffit detailing can lead to condensation issues, material degradation, and occupant discomfort. The session will offer best practices for detailing soffits to ensure continuity of air and water barriers, maintain thermal continuity, and avoid costly failures. Special focus will be given to vented vs. unvented soffit strategies, material transitions, and performance-driven design decisions. This session is intended for building enclosure consultants, architects, and contractors involved in the design, evaluation, or rehabilitation of building enclosure systems. Attendees will leave with actionable detailing strategies, diagnostic red flags, and a deeper understanding of the critical role soffits play in high-performing enclosures—not just for aesthetics, but for durability, comfort, and code compliance.
