Building Enclosure Performance Verification Testing: Changing the Paradigm—Supporting Sustainability, Resilience, and ESG Goals
EXPAND DETAILS
Knowledge Level: Introductory
Session Topics(s): BECx
Credits: This activity has been approved for 1.0 IIBEC CEH. | This session is approved for 1.0 AIA LU/HSW
Learning Objectives
At the end of this session, the learner will be able to:
- Identify at least three ways that building enclosure (or “envelope”) performance verification testing contributes to sustainability and resilience in buildings.
- Distinguish between code-minimum enclosure testing and testing strategies that proactively support long-term sustainability and resilience goals.
- Explain how integrating enclosure testing into the design, construction, and commissioning phases can reduce operational costs and environmental risk for building owners.
- Summarize the benefits of building enclosure testing for asset life cycle extension, citing at least two metrics (e.g., energy savings, maintenance reduction) that can be improved through proactive verification.
Description
Building enclosure performance verification testing plays a critical role in advancing sustainability, resilience, and the achievement of environmental, social, and governance (ESG) goals in the built environment. The building enclosure directly impacts energy efficiency, occupant health, and structural durability. The current paradigm of such testing largely revolves around satisfying codes and standards. However, applying testing through the lens of sustainability and resiliency may have a much more impactful payoff by minimizing energy loss, reducing greenhouse gas emissions, extending asset life cycles, reducing operating costs, and supporting healthier indoor environments. This presentation will inform commissioning agents, designers, consultants, and project owners on the value of integrating testing into design, construction, and operations to align building performance with sustainability objectives, demonstrate ESG leadership, and future-proof their assets against environmental and regulatory challenges. As climate change intensifies and ESG standards evolve, building enclosure verification testing should be considered a foundational practice for responsible, high-performing, and resilient buildings.

Understanding Fire Resistant Code Standards and Ensuring Roofs Meet those Requirements
EXPAND DETAILS
Knowledge Level: Intermediate
Session Topics(s): R
Prerequisite Knowledge:
- The attendee should be familiar with the roofing systems commonly specified and installed.
- The attendee should be familiar with the building code requirements for roofs.
Credits: This activity has been approved for 1.0 IIBEC CEH. | This session is approved for 1.0 AIA LU/HSW.
Learning Objectives
At the end of this session, the learner will be able to:
- Evaluate the different testing standards required to meet Class A, B, or C standards.
- Review the key variables in the testing that create the misunderstandings related to Class A, B, or C rated materials, and Class A, B, or C rated roofing assemblies.
- Explain how integrating enclosure testing into the design, construction, and commissioning phases can reduce operational costs and environmental risk for building owners.
- Discuss the development of the building codes as they relate to fire resistance of roof coverings and what the current building codes standards require.
- Identify the variables required to properly specify a roofing assembly that meets the appropriate fire resistance requirements for the roofing assembly.
Description
Not unlike the recent Los Angeles, California, fires, burning brands blowing from roof to roof destroyed more than 17,000 buildings in the infamous 1871 Chicago, Illinois, fire. This and many more similar fires in the late 19th century have led to the development of fire resistance standards for roof coverings. Those standards are the basis for today’s UL790 and ASTM E108 requirements found in today’s IBC. Most of us know Class A, B, and C fire ratings but do not understand the nuances of these ratings. As a result, every year millions of square feet of roofing are installed that do not meet the building code standards for which they are designed to prevent the types of devastating fire losses we see today. The roofing material may have a Class A or B rating, but the roofing assembly may only meet a Class C or is not rated at all. The assembly may have a Class A or B rating on a steel deck but only a Class C on a plywood deck. This presentation will provide an overview and key variables of the testing methods, the code requirements, and the system nuances required to meet the required fire-resistant standards.

Innovative Stone Panels Meet Historical and LEED Requirements
EXPAND DETAILS
Knowledge Level: Introductory
Session Topics(s): EW
Credits: This activity has been approved for 1.0 IIBEC CEH. | This session is approved for 1.0 AIA LU/HSW.
Learning Objectives
At the end of this session, the learner will be able to:
- Explain installation differences between conventional stone panels and stone veneer composite systems.
- Recognize safety hazards in failed wall panel conditions.
- Justify why innovative ideas require investigation and validation through testing and evaluation.
- Discuss a presented case study and relate it to familiar examples for historical requirements and LEED points.
Description
A 52-story white marble-clad high-rise in downtown Dallas, Texas, built in 1965, was the center of attention for a 5-star multi-use remodel aiming to meet historical requirements and attain LEED Platinum certification. Unfortunately, the marble panels had started to crack and fall, creating life safety hazards for the public and imminent danger. The design team’s plan was to demo the marble and quarry new marble from Greece to meet historical requirements. The new marble was to be fabricated onto a lightweight aluminum honeycomb clip and rail system, lightening the structural load and creating a sustainable solution. However, a better plan, which would meet both LEED and historical requirements, was proposed. In this session, the presenter will share the challenges of proving an idea through evaluation, testing, price analysis, schedule planning, and construction coordination while in a tight area next to the DART Rail system at a heightened risk. This presentation will highlight challenges of working on a team with multiple viewpoints and priorities: consultant, contractor, architect, and owner. Upon completion in 2020, this building opened as one of the largest adaptive reuse projects in the state of Texas. The mixed-use development includes office, residential, retail, and a 219-room hotel.

Soffit Detailing Strategies for Performance and Durability in Modern Building Enclosures
EXPAND DETAILS
Knowledge Level: Intermediate
Session Topics(s): EW
Credits: This activity has been approved for 1.0 IIBEC CEH. | This session is approved for 1.0 AIA LU/HSW
Prerequisite Knowledge:
Attendees should have a basic understanding of exterior wall assemblies and building enclosure principles. Familiarity with moisture management strategies, thermal performance considerations, and typical construction detailing practices – particularly at transitions such as eaves and soffits – is recommended. Experience with reviewing or developing construction details is beneficial but not necessary.
Learning Objectives
At the end of this session, the learner will be able to:
- Identify at least three common modes of failure in soffit detailing that can lead to water intrusion or premature material degradation in exterior wall systems.
- Explain the role of soffit design in maintaining moisture control, thermal continuity, and enclosure durability in ventilated and non-ventilated assemblies.
- Evaluate construction details for soffit transitions to recognize potential issues related to venting, drainage, and material compatibility.
- Apply practical strategies for improving soffit detailing on future projects by referencing real-world case studies and industry best practices.
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.

How to Investigate the Impossible
EXPAND DETAILS
Knowledge Level: Introductory
Session Topics(s): WP, EW, R
Credits: This activity has been approved for 1.0 IIBEC CEH. | This session is approved for 1.0 AIA LU/Elective
Learning Objectives
At the end of this session, the learner will be able to:
- Explain the factors that lead to the most difficult water intrusion investigations.
- Review techniques, methods, and tools that can be used for complex water penetration investigations.
- Discuss how water moves through materials, including capillary action, diffusion, vapor transmission, and mass transport under pressure.
- Describe the relative effectiveness of different repair techniques.
Description
If you have ever spent months catching dripping water in a bucket or corralling unwanted moisture with sandbags and the source of water intrusion still eludes you, what can you do to figure out the problem? After conventional flood tests and Band-Aid repairs have failed to address the issue, what are the next steps? This presentation addresses these questions by examining two case studies of water penetration in existing buildings. This presentation will delve into the investigative methods, diagnosis, and final repair strategy used in two scenarios where the source and cause of water penetration were far from obvious. For both case studies, we will explain the multistep investigative process, including red herrings, diagnostic tests, monitoring activities, and investigative repairs. Factors that limit investigations, such as the availability of as-built construction documentation, budget limitations, physical access, and disruption to building users will be discussed. Finally, the reasons why the initial repairs were ineffective and how our investigative findings led to the appropriate repair strategies will be reviewed.

Is Wood Good? Wind Uplift Performance of Mechanically Attached Roof Assemblies
EXPAND DETAILS
Knowledge Level: Intermediate
Session Topics(s): R
Credits: This activity has been approved for 1.0 IIBEC CEH. | This session is approved for 1.0 AIA LU/Elective
Learning Objectives
At the end of this session, the learner will be able to:
- Describe the wind performance of mechanically attached membranes over three different types of wood decks.
- Discuss the performance small-scale dynamic testing.
- Discuss wind uplift performance based on full-scale dynamic testing.
- Discuss the key recommendations for commercial roofs in terms of wood deck types for use with mechanically attached membranes.
Description
Wood decking is commonly used in residential roofing assemblies and is gaining popularity in commercial roofs due to its ease of installation and cost-effectiveness. However, numerous instances of failures and damages have been noted in oriented standard board (OSB) decking used in mechanically attached systems that were less than 5 years old, despite not being exposed to significant weather events. To address these failures and to identify acceptable wood deck types for commercial roofing, Special Interest Group on Dynamic Evaluation of Roofing Systems (SIGDERS) completed extensive dynamic wind uplift experiments on mechanically attached membrane roof assemblies with wood decking. This comprehensive study involved both dynamic small-scale and system-level investigations following CSA A123.21, “Standard Test Method for the Dynamic Wind Uplift Resistance of Membrane-Roofing Systems.” The study assessed four different wood deck types, various mechanically attached membrane types, and two commonly used fasteners from various sources while keeping the other above deck components consistent. This presentation will discuss the data from over 200 small-scale specimens along with wind uplift resistance findings from more than 20 full-scale mock-ups. Key insights into the performance of various wood decks and recommendations tailored specifically to commercial mechanically attached membrane roof assemblies will also be presented.

Effects of Interior Air Management Systems on Exterior Enclosure Performance
EXPAND DETAILS
Knowledge Level: Advanced
Session Topics(s): EW, BECx
Credits: This activity has been approved for 1.0 IIBEC CEH. | This session is approved for 1.0 AIA LU/HSW
Prerequisite Knowledge:
Attendees should have an understanding of basic air barrier design and specifications, including code requirements for the air barrier assembly. They should also have a basic understanding of requirements such as standardized testing for air pressure minimum performance of fenestration and glazing systems, both in situ and manufacturer design lab performance tests. Attendees should have a basic understanding of the general function and performance of air management Heating Ventilation and Air Conditioning (HVAC) systems. They should also have a basic understanding of the physical nature of air pressure differential on a building enclosure that causes high positive and high negative pressure zones based on building exposure and based on building design parameters such as wall/roof height, roof slope, parapet, surrounding terrain, etc.
Learning Objectives
At the end of this session, the learner will be able to:
- Recognize that enclosure systems and HVAC systems performance in midrise buildings, particularly in flat open terrain, can be adversely affected by indoor/outdoor air pressure differential. Normal and anticipated annual storm events can have an effect on the enclosure design pressure when considered to work in conjunction with the interior air management equipment; the two together can potentially overwhelm the cladding system design, causing unanticipated leaks (air and moisture) into the building.
- Discuss that as part of building enclosure and HVAC commissioning evaluation of a facility, the design of the air management system can have direct implications to the performance of a cladding system and can affect the design wind pressure evaluation of the building.
- Evaluate the real time performance of interior pressure induced by the HVAC system as part of the mode of failure or causation when performing failure analysis following water penetration into a new or aged building.
- Explain that diagnostic protocols for suspect failure of a building enclosure based on water infiltration should include the building systems direct digital controls records and history as well as use of temporary localized interior data loggers that can record interior barometric pressure, relative humidity, and temperature. The data from this diagnostic equipment can help point to failures and deficiencies in the air management system, which when combined with normal weather conditions such as wind storm events could cause water leaks that would be assumed to result from cladding or roofing installation failures.
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.

Session Topics(s): EW
Credits: This activity has been approved for 1.0 IIBEC CEH. | This session is approved for 1.0 AIA LU/HSW
Learning Objectives
At the end of this session, the learner will be able to:
- Describe the four building enclosure phenomena of liquid water intrusion, air infiltration and exfiltration, water vapor migration, and heat transfer.
- Explain the differences between barrier wall systems and rainscreen wall systems.
- Identify the importance of maintaining continuity in subassemblies that manage the four building enclosure phenomena in barrier wall systems and rainscreen wall systems.
- Discuss the differences between transient and steady state analyses for the four building enclosure phenomena.
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.

Hail Impact Testing of Modified Bitumen Roof Membranes
EXPAND DETAILS
Knowledge Level: Introductory
Session Topics(s): R
Credits: This activity has been approved for 1.0 IIBEC CEH. | This session is approved for 1.0 AIA LU/HSW
Learning Objectives
At the end of this session, the learner will be able to:
- Discuss ASTM D3746, Standard Test Method for Impact Resistance of Bituminous Roofing Systems, and its procedures and parameters.
- Describe a process called “image analysis,” which uses a computer program to analyze high-resolution photographs to identify features of interest, particularly granules and exposed bitumen.
- Recognize variations in modified bitumen membranes of various ages including granule quantities and exposed bitumen area.
- Explain the differences observed between roofing samples containing gypsum and wood fiber cover boards regarding hail impact.
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.

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.

Addressing the General Design Requirements: Methods for Managing Water and Accommodating Differential Movement in Masonry Veneer
EXPAND DETAILS
Knowledge Level: Introductory
Session Topics(s): EW, WP
Credits: This activity has been approved for 1.0 IIBEC CEH. | This session is approved for 1.0 AIA LU/HSW
Prerequisite Knowledge:
Attendees will need a basic understanding of the design and construction of exterior walls. This presentation will briefly review the full masonry veneer assembly, including components such as anchored masonry veneer ties, adhered veneer lath and fasteners, shelf angles/lintels, and penetrations. Details associated with the drainage plane, structure/facade interaction, and transitions to dissimilar materials will be the primary focus of this presentation.
Learning Objectives
At the end of this session, the learner will be able to:
- Review the strengths and weaknesses of nonexplicit code requirements for accommodating differential movement and managing water infiltration.
- Discuss the intent of differential movement requirements and the repercussions of noncompliance.
- Explain the significance of water management requirements and the repercussions of noncompliance.
- Explore methods of designing and constructing to meet differential movement and water management requirements via a case study.
Description
Masonry veneer is a prevalent building facade material used internationally due to its attractive aesthetics and durability. Although there are explicit code requirements for the attachment of masonry veneer, the International Building Code (IBC) and its referenced masonry code, TMS 402, include only general design requirements for accommodating differential movement and managing water penetration within veneer. This lack of specificity provides the designer with freedom to use a myriad of modern materials and for manufacturers to continue to push the envelope, no pun intended, for improving and advancing masonry construction. However, with new building materials, construction methods, and inexperienced design professionals comes the risk of new problems and repetition of old problems in new ways. As building enclosures become more complicated, it is more important than ever to remember and understand the intended performance of the building enclosure system to avoid omission of critical details and premature failure of the masonry veneer. This presentation will discuss the masonry veneer code requirements and will review the intended system performance related to water management and differential movement. Additionally, we will explore common ways for meeting code intent with modern enclosure materials to achieve long-term durability of masonry veneer construction.

Practical Tools for Managing Building Enclosure Projects with Consistency and Quality
EXPAND DETAILS
Knowledge Level: Intermediate
Session Topics(s): BECx
Credits: This activity has been approved for 1.0 IIBEC CEH. | This session is approved for 1.0 AIA LU/HSW
Prerequisite Knowledge:
It is recommended that attendees are familiar with the basic phases of a building enclosure project and have some exposure to construction administration or quality assurance tasks, either in design or consulting roles.
Learning Objectives
At the end of this session, the learner will be able to:
- Describe the components of a project management framework specific to building enclosure consulting, including workflows, quality assurance (QA)/quality control (QC) checklists, and performance tracking methods.
- Identify common challenges within complex enclosure projects, such as miscommunication, team expertise gaps, and process scalability, and explain approaches to address them.
- Analyze how structured project management tools improve collaboration and consistency across a range of project types, including facade retrofits and roof replacements.
- Apply at least one project management strategy to support improved coordination, quality assurance, or efficiency within their own building enclosure projects.
Description
Building enclosure projects are complex undertakings that require strong collaboration among owners, contractors, architects, and consultants. Enclosure consultants play a pivotal role in supporting the design and construction of the enclosure by establishing performance goals, managing risks, and addressing technical challenges. However, without structured workflows and established quality assurance (QA)/quality control (QC) processes, these projects can face delays, miscommunication, and potential liability. This presentation will outline practical approaches for managing building enclosure projects more effectively across all phases- design, pre-construction, and execution. It introduces a project management approach tailored to enclosure consulting that includes streamlined workflows, QA/QC checklists, and performance tracking methods. Real-world examples, including facade retrofits, roof replacements, and energy code compliance upgrades, will demonstrate how these frameworks can be adapted to different project types. Each example will be tied to specific challenges, with discussion on how the tools were applied to improve coordination, reduce errors, and guide decision-making. These case studies ground the strategies in actual project experience, highlighting lessons learned and what we would adjust next time. This presentation will also explore how to scale these tools for large or small projects, support teams with varying levels of experience, and encourage adoption without adding complexity. Attendees will be provided with practical strategies they can begin using right away to improve communication, simplify coordination, and support consistent quality across their own work.
