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. li>
• 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.

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.

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.

Description

The Richard Gilder Center for Science, Education, and Innovation is the newest addition to the American Museum of Natural History in New York City, originally constructed in 1877. This six-story expansion adds 230,000 square feet of new space for new exhibits, classrooms, learning labs, offices, and education spaces to the existing building, and was completed in 2023. The new wing and accompanying renovations were designed by Studio Gang Architects with Davis Brody Bond acting as Architect of Record, and Buro Happold as the exterior facade consultant. Buro Happold partnered with WW Glass and Island Exterior Fabricators to fabricate and install the exterior facade which wraps the building of curving steel and natural granite stone. This presentation will discuss the tools and processes used to create the complicated geometric façade, and the challenges and solutions related to preserving a high standard of performance and quality control. The panelization of the stone facade to fit the geometry of the design and the development of the steel frame to support individual stone pieces will be reviewed. Additionally, we will review the design assist and quality assurance procedures which included facade performance mock-up and testing, factory inspections during fabrication, on-site construction administration and reporting, and post-installation field testing.

Credits: This activity has been approved for 1.0 IIBEC CEH.

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 attendee 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.

Prerequisite Knowledge:  Learners should have a basic understanding of low-slope roofing systems and building code compliance (IBC). Familiarity with wind uplift and wind-borne debris resistance concepts. An awareness of 2024 International Building Code (IBC), ASCE/SEI 7-22 Minimum Design Loads and Associated Criteria for Buildings and Other Structures and ICC/NSSA 500 Standard for the Design and Construction of Storm Shelters.

Learning Objectives
At the end of this session, the attendee will be able to:

• Identify key updates in the 2024 International Building Code (IBC) related to low-slope roofing.
• Identify key updates in ASCE 7-22 and apply ICC 500 for low-slope roofing wind resistance and wind-borne debris protection specific to critical and essential facilities (Risk Category III and IV) and storm shelters.
• Apply FEMA’s National Risk Index (NRI) data to better evaluate site-specific natural hazard risks and inform roofing design decisions.
• Evaluate strategies for integrating secondary membrane systems and other resilient roofing enhancements that exceed code minimums, with attention to constructability and performance.

Description
As climate change drives more frequent and severe weather events, design professionals must increasingly address resilience in critical and essential facilities (Risk Categories III & IV) and community storm shelters. Low-slope roofing systems play a vital role in protecting these structures against rain, wind and hail. The 2024 International Building Code (IBC), ASCE/SEI 7-22and the ICC/NSSA 500 introduce new and revised provisions that influence roof system design. These updates include enhanced wind resistance design requirements and large-missile impact testing for roofing components. This presentation will examine these changes through a technical lens while incorporating an analysis of the IBC, ASCE/SEI 7-22 and the ICC/NSSA 500, and jurisdictional adoptions. It will also explore the use of FEMA’s National Risk Index (NRI) to assess project-specific hazard vulnerabilities and guide location-based mitigation strategies. With a focus on real-world applications and technical credibility, this session equips design professionals with informed strategies to specify roofing systems that go beyond minimum code—such as implementing secondary membranes for redundancy and resilience. Contractors will also benefit from understanding these enhancements to support better collaboration during installation.

Learning Objectives
At the end of this session, the attendee will be able to:

•  
• Examine each stakeholder’s role in verifying that the proposed window systems meet the project requirements.
• Analyze how small changes in window design or installation can affect window performance.
• Examine different methods the design team can use to help mitigate the issues associated with windows.

Description
Windows are some of the most prominent features on buildings and generate some of the most innovative designs in recent years. However, fenestration can also disrupt the continuity of the exterior wall protection and tend to cause the most turmoil on projects. Windows produce many headaches in the construction process, including poor specifications, manufacturers not fully testing their designs, and missteps in the install. This presentation will review the basics of specifying windows and the window industry and how it is designed and regulated. Project examples to highlight the issues with fenestration, including window walls, mulled windows, sliding glass doors, folding glass doors, and curtainwall, will be discussed. Best practices to mitigate these issues during the design and construction phases will be shared.

Familiarity with forensic investigation techniques and nondestructive evaluation methods will be beneficial. Additionally, knowledge of common construction practices and deficiencies, especially those prevalent in mid-20th century buildings, will help participants fully grasp the case study and proposed repair strategies.

Learning Objectives
At the end of this session, the attendee will be able to:

• Explain the purpose and methods of nondestructive evaluation (NDE) techniques, such as the use of metal detection for veneer anchorage location, as well as plumbness measurements, to understand how these assessments help in evaluating the structural integrity of masonry veneer walls.
• Identify the main factors that led to the wall collapse based on the data collected from the investigation and lab analysis.
• Recognize common construction deficiencies found in 1950s buildings, such as inadequate veneer anchorage spacing, use of undersized materials, and poor anchorage methods, as well as to understand their impact on the building's structural performance.
• Describe effective repair strategies for masonry veneer walls, such as helical pin installations and brick replacement, informed by the findings from NDE surveys, testing, and exploratory openings.

Description
This presentation will discuss the background, failure investigation, and proposed repair strategies at a residential complex in Long Island, New York, following a brick masonry veneer wall collapse during a winter storm. The forensic assessment of the veneer condition—including examination of veneer anchorage, material and construction deficiencies, and environmental factors—to uncover the contributing causes of the failure will be highlighted. A summary of the nondestructive evaluation and testing used to evaluate the condition of the remaining brick veneer conditions, development of the subsequent proposed repair strategies, and the methods that were undertaken to validate the feasibility and efficacy of the repairs will be presented. Participants will gain valuable insights into the practical aspects of conducting failure investigations, including the identification of inadequate construction practices and the application of effective repair solutions, as well as testing methods that can be incorporated into veneer assessments. Methods to assess and address structural vulnerabilities of veneer systems and enhance the durability of masonry veneer and wood framed structures will be reviewed. Structural engineers, architects, and construction professionals interested in failure investigations and masonry veneer repair techniques will benefit from this presentation.

  • Discuss necessary roof drainage code enhancements, using real-world case studies presented.

  Description
  This session addresses crucial updates needed in roof drainage codes to manage severe rain events effectively, featuring case studies that underscore the urgency of these changes. Focusing on the following five key modifications, this session is developed with the roofing design professional, engineer, and architect in mind. First, advocating for a unified method for the UPC, NPC, NSPC, or IPC codes in calculating roof drainage requirements, including intense short-duration rainfall typical of 100-year storms. Second, proposing to eliminate sump pits that often fail to meet the required drainage slopes. Third, defining “observable” overflows and the recommendation of positioning them above windows or exterior doors for enhanced visibility and safety, as well as the location of collector heads to avoid water ponding on roofs. Fourth, reviewing the idea of doubling the size of overflow drains compared to main roof drains to ensure functionality during blockages. Fifth, reviewing the necessity of adding secondary overflow drains in reroofing projects on existing buildings, which are currently not mandated. Case studies will illustrate real-world scenarios where deficiencies in current standards have compromised safety, underscoring the necessity for the proposed code enhancements. This session equips learners with the information they need to advocate for essential enhancements to improve building resilience and public safety.

Prerequisite Knowledge:  Learners should have a basic understanding of different waterproofing approaches and systems.

Learning Objectives
At the end of this session, the attendee will be able to:

• Identify the advantages and limitations of shotcrete as an alternative to traditional cast-in-place concrete for below-grade foundation walls..
• Evaluate the impacts of shotcrete application on the performance and installation of below-grade waterproofing systems.
• Analyze real-world case studies to understand common challenges and lessons learned from projects using shotcrete foundation walls.
• Develop strategies for effectively integrating shotcrete into building enclosure design while mitigating potential performance risks.

Description
As the demands for accelerated construction schedules and cost-effective foundation systems continue to rise, shotcrete has emerged as a compelling alternative to more traditional cast-in-place concrete for below-grade foundation walls. While the application of shotcrete offers notable advantages in terms of construction schedule and cost, it also introduces distinct challenges related to the installation and performance of below-grade waterproofing systems. This presentation will examine the practical implications of using shotcrete for foundation walls, with a focus on below-grade waterproofing systems and details. We will review case studies from recent projects to illustrate lessons learned and to discuss strategies to mitigate the potential downfalls of shotcrete foundation walls. Learners will gain a deeper understanding of when and how shotcrete can be effectively integrated into enclosure design, and where it may introduce risks that require strategic forethought and mitigation.

Learning Objectives
At the end of this session, the learner will be able to:

• Identify differences in the thermal characteristics of the measured systems (curtainwall and window wall).
• Discuss the impact of interior insulation and mullion wraps on the thermal performance of these systems.
• Identify differences between the study’s testing arrangement at Oak Ridge National Laboratory (ORNL) and common industry test methods (e.g., ASTM C1199 and NFRC 102).
• Interpret how physical test results may inform future design strategies for improving spandrel assembly thermal performance.

Description
Gaps in the industry’s understanding of the thermal performance of opaque (i.e., spandrel) sections of glazed wall systems have led to inconsistent results and discrepancies with real-world performance, and they have stalled the innovation necessary to achieve energy-efficient systems. This presentation will provide an update on Phase 2 of a multiyear, multiphase research study aimed at closing this performance gap. Specifically, this presentation will focus on presenting results from physical testing conducted at Oak Ridge National Laboratory (ORNL). The results will include measurements of several variations of thermally broken aluminum stick-built and unitized curtainwall along with a window wall system. Differences in the thermal behavior of the tested spandrel assemblies will be highlighted along with the effect of several thermal upgrade options. The study is known as the “Thermal Performance of Spandrel Assemblies in Glazing Systems” and is funded by the Charles Pankow Foundation with additional support from many project partners. Phase 1 of the research report is available free online. Additionally, the research aims to inform the development of techniques and tools for design professionals to accurately model, simulate, and predict building energy performance during the design stage. These techniques are crucial as energy efficiency codes advance to include absolute metrics for building energy use.

Learning Objectives
At the end of this session, the learner will be able to:

• Identify three primary contributors to condensation in refrigerated process/cold storage facilities.
• Define specific areas of concern for condensation in industrial roofing projects..
•  
• Evaluate best practices for long-term performance of roofing systems in refrigerated/cold storage facilities.

Description
Industrial roofing projects often come with unique challenges and unexpected obstacles that demand practical, innovative solutions. This presentation will explore case studies demonstrating the three main contributors (infiltration, conductance, and saturation) to condensation in refrigerated processing and cold storage operations, prevention and mitigation strategies, and multidisciplinary coordination for long-term performance. In these specialized environments, where temperature differentials are extreme, a well-installed air barrier system is essential to prevent moisture intrusion and potential roof system failures. Air barriers also play a critical role in maintaining temperature control, energy efficiency, and overall performance of the interior refrigerated environment. A discussion of how these systems must be designed to handle the unique challenges posed by rooftop penetrations and terminations, continuous low temperatures, high humidity differentials, and the need for airtight enclosures will take place. Practical insights will be shared on best practices for selecting materials that resist thermal bridging and moisture, as well as techniques for proper installation to ensure long-term roof system performance and durability. For roofing and building enclosure professionals, this session will provide a deeper technical perspective on how to optimize roofing and air barrier performance in refrigerated processing and cold storage facilities and how to ensure these systems exceed client expectations in terms of efficiency, reliability, and long-term performance.

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.

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.
•  

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.

Learning Objectives
At the end of this session, the learner will be able to:

• Approach exterior cladding, building envelope, and components and cladding stud framing design without fully knowing the existing construction.
• Review and design around existing conditions through a design build approach.
• Better navigate changes that occur through construction.
• Ensure code compliance with new changes to existing structures.
•  

Description
A historic government building located in Denver, Colorado, with no existing drawings on the overall construction of the building exterior will be presented as a case study in design and construction project administration for a major exterior cladding rehabilitation project. The exterior cladding includes granite panels, EIFS, adhered tile, windows, doors, louvers, canopy, fascia, and roof tie-in with a stud framed back-up wall assembly. The fact that the owner/client limited the ability to investigate and verify construction during the design phase led to more delegated “engineer to verify in field” design challenges during construction. These field findings led to identifying several construction-related issues with the existing exterior wall assembly and subsequently additional scope to provide proper backup wall for the construction of new exterior cladding assemblies. This session will walk through the initial findings of what was compiled from the original design drawings and the additional conditions discovered during the construction phase that changed portions of the originally anticipated design. We will then navigate through the changes that were made with the client and contractor and how those were managed during the construction period to lead to a successful building enclosure project.

Learning Objectives
At the end of this session, the learner will be able to:

• Discuss the unconventional building and roof design principles of a Frank Lloyd Wright Usonian building and how rebuilding the low-slope roof on a modernist-style Usonian building such as Pearce House is a tedious, challenging process.
• Recognize how the roof plays an integral role in the overall aesthetics, functionality, and historical integrity of a Usonian construction such as Pearce House.
• Describe the unique plane geometry associated with low-sloped roofs commonly found on a Usonian building with a focus on drainage design and waterproofing practices.
• Observe how roofing system technology has evolved in the 70 years since the roof at the Pearce House was originally constructed.
•  

Description
Pearce House stands as a striking embodiment of Frank Lloyd Wright’s Usonian vision, completed in 1955 as a bold statement of form and function. At its core is the low-slope roof—not just a structural necessity, but a modernist architectural centerpiece. Its dramatic angles, curves, and intersecting planes, while visually compelling, pose a serious challenge for waterproofing, especially in Wright’s time. In the 1950s, constructing a roof this complex without leaks was nearly impossible. Decades of deferred maintenance only amplified the deterioration. As a result, restoring the Pearce House roof wasn’t just a repair job—it was a demanding architectural rescue mission. Restoration called for a balance between preserving the integrity of Wright’s original design while using present-day building standards. There were a multitude of extensive technical challenges including: rebuilding the entire roof structure; redesigning the drainage system; reconstructing the wide and layered perimeter fascia/raised edge, and reworking the simplistic concrete masonry unit (CMU) wall copings. Roof design and construction were further complicated by new mechanical, electrical, plumbing (MEP) and fire-suppression systems, all installed directly on the top side of the roof deck. This presentation highlights how those challenges were appropriately addressed with current practices, including present-day materials, and today’s artisans.

At the end of this session, the learner will be able to:

• Review recent artificial intelligence (AI) advancements that came online in 2025 or will come online in 2026.
• Discuss how to get started with identifying, testing, and implementing AI within a process or organization.
• Compare and contrast technology and AI adoption barriers that people and organizations face when wanting to advance their processes.
• Gain insight into likely upcoming (i.e., 2+ year) AI-enabled use cases for building enclosure projects.
•  

Description
Artificial intelligence (AI) continues to advance, with new applications and platforms coming online on a nearly regular basis. Many of these companies, platforms, and technologies will have the potential to impact how the building enclosure industry operates, both in the near and long term. Following the 2025 introductory AI session, this session will provide an update regarding new and upcoming technologies that will demonstrate significant potential, along with discussing what is likely to come in the next few years. Furthermore, this session will address the most pressing question that most building enclosure and roofing consultants face today: “How do I get started?” Beyond knowing about new AI-enabled technology and use cases, this discussion will focus on best practices and lessons learned for those eager to try or do more with AI. The learner can expect to walk away with a clear path for testing, refining, and/or deploying AI within their processes and organizations. Tangible next steps for novices and experienced AI users alike will be a primary focus.

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.

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.

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.
• 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.

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.

Prerequisite Knowledge: A combination of basic knowledge in building science, roofing materials, moisture management, energy efficiency, and construction design would be helpful to fully grasp the concepts presented in this session.

Learning Objectives
At the end of this session, the learner will be able to:

• Discuss the modes of moisture transport in roofing assemblies, with an emphasis on the dominant role of moisture-laden air.
• Describe design strategies and advanced moisture management solutions that protect against condensation buildup and extend roof system longevity.
• Evaluate the risks associated with air leakage, condensation buildup, including material degradation, compromised thermal performance, and increased wind uplift effects.
• Review how permeable vapor retarders block moisture-laden air while allowing balanced vapor diffusion, providing effective moisture control without full vapor restriction.

Description
Effective moisture control is essential for extending the service life and maintaining the performance of low-slope commercial roofing systems. While traditional vapor retarders and air barriers help reduce air leakage, we will discuss newer technologies that offer more adaptive solutions that align with today’s roof performance demands. This session explores the next generation of moisture management, permeable vapor retarders and air barriers, and their role in mitigating moisture intrusion, improving energy efficiency, and enhancing wind uplift resistance. Attendees will examine the science behind condensation and its often-overlooked consequences, including material degradation, reduced thermal performance, and premature roofing failures driven by uncontrolled moisture-laden air movement. Through current research and real-world case studies, this presentation highlights how strategic design and installation of these advanced materials can significantly increase roof resilience, extend system longevity, and reduce long-term operational costs—ultimately offering better protection for the entire building envelope.

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.

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.
