Session Description

Artificial intelligence (AI) solidified itself as the exciting buzzword and curiosity for the architecture, engineering, and construction (A/E/C) industries in 2023. Truly, there are numerous applications that can and likely will be explored, developed, and scaled for the A/E/C industry, in the near, mid, and long term. However, to date, AI tends to be more discussion-oriented and vague than focused on specific solutions and practical implementations that solve real problems that exist today. Significant discussion speaks to the potential of text, image, and video generation, but has been nonspecific on how someone in the industry might try, customize, implement, or standardize these technologies into their day-to-day workflows. Further, we are now at the point of seeing real examples of AI use cases specific to the building enclosure industry, which can be explored to drive new efficiencies and improved business operations. This presentation will provide real insights on how to think about AI, where and how to implement specific technologies, and current solutions that are available, addressing the biggest questions that firms and individuals have today. We will go beyond ChatGPT queries and discuss the potential for the building enclosure industry.

Session Description

Built in 1914, the Burk Burnett Building was the first “skyscraper” constructed in Fort Worth, Texas. The twelve-story terra cotta and brick cladded building stands as an iconic piece of architecture in the famous Sundance Square. However, a piece of the terra cotta cladding unexpectedly fell from the building which triggered an emergency safety assessment and installation of overhead protection in late 2018. The initial evaluation revealed critical areas of instability, prompting the removal and storage of damaged terra cotta units and the develop of repair documents. After a three-year hiatus, the building was re-evaluated via drone survey in 2022 prior to the start of construction in 2023. Over the 14-month construction period, Walter P Moore meticulously oversaw the repair process and continued to find areas of deterioration requiring investigation and repair. Through periodic reviews and diligent monitoring, Walter P Moore ensured each repair adhered to the highest standard, safeguarding Burk Burnett’s historic charm and structural integrity. This presentation will discuss the emergency response, the evaluation and reevaluation, the engineered design and detailing of the repair effort, and the joint effort of the engineer and general contractor during construction that played a key role in the overall success of the project.

Session Description

Roofing systems play a crucial role in achieving seamless integration between horizontal and vertical enclosure systems. As building enclosure performance requirements continue to rise, roofing systems of a building’s enclosure become more rigorous, and enclosure systems become higher performing. To meet this demand, roofing systems are often called upon to ensure continuity in (thermal, airtightness, and waterproofing aspects) between horizontal and vertical enclosure systems. Often, the detailing, material compatibility, and durability at roofing transitions can ensure the overall effectiveness of the building’s enclosure performance. This presentation looks to explore some of the challenges often overlooked during the design of roofing transitions and emphasizes the importance of discussing detailing at edge conditions. By addressing material compatibility and durability and ensuring effective continuity, roofing systems contribute significantly to the overall effectiveness of a building’s enclosure performance.

Learning Objectives
At the conclusion of this session, participants will be able to:

• Identify common “all-in-one” exterior wall systems.
• Review the heightened attention needed during installation of such systems.
• Assess the potential failure that can occur when departing from an idealized installation through review of case studies.
• Explore best practice considerations for use of such systems when considering application, performance, and overall objectives for a project.

Session Description

Exterior wall systems using insulated metal panels, adhered masonry, and exterior sheathing with integrated water-resistive barriers (WRBs) are often appealing due to their marketed “all-in-one” characteristics. They can present advantages, such as reduced labor and/or material costs and reduced overall installation time, while presumably providing the same or better code-compliance, aesthetics, and performance relative to their traditional multicomponent exterior wall enclosure counterparts (i.e., rainscreen metal panel systems, conventional veneer masonry systems, and other exterior wall coverings with sheathing and sheet- or liquid-applied WRBs). However, these systems can and do require increased attention and a more methodical approach during a systematic installation because they often lack the inherent redundancy and/or durability of traditional systems. This increased attention necessary during installation may also not be recognized. Even a slight deviation with installation of such systems can lead to premature failure and substantial remediation. This session will explore the potential adverse outcomes that can occur when seemingly minor departures from an idealized installation occur—departures that may not prove as significant for their traditional counterparts.

Learning Objectives
At the conclusion of this session, participants will be able to:

• Articulate new key performance indicators for achieving net zero, carbon neutral goals.
• Describe the process for evaluating existing buildings and strategies to improve operational carbon, such as enclosure upgrades, electrification, and decarbonization of HVAC systems.
• Analyze the challenges associated with repositioning existing buildings to meet net zero, carbon neutral goals.
• Reflect on the lessons learned from the case study that can be implemented by other project teams.

Session Description

In the face of impending climate change, the state and municipalities of Massachusetts are developing major policy changes, such as the Building Emissions Reduction and Disclosure Ordinance (BERDO), to decarbonize buildings. These policy changes challenge existing building owners to evaluate strategies that improve operational carbon, such as enclosure upgrades and electrification and decarbonization of HVAC systems. These regulations, however, overlook the embodied carbon associated with the life cycle of materials and their installations. Addressing emissions related to operational carbon is an easy and tangible metric to pursue, but the recommended solutions should not be too quick to overlook the ripple effect design and construction applications have.  Integrative energy modeling processes have evolved into having a greater impact on the design and decarbonization strategies, resulting in a holistic collaborative design approach while focusing on new key performance indicators.

Using a recently completed project case study in Needham, Massachusetts, the first net-zero, carbon-neutral office building repositioning project in the state, this presentation will explain the process for achieving net zero, carbon-neutral within existing buildings, as well as discuss challenges associated with achieving those goals. General takeaways that other project teams should consider when reviewing existing buildings will be provided.

Learning Objectives
At the conclusion of this session, participants will be able to:

• Identify common facade types and components more prone to detachment and collapse.
• Recognize the primary causes of facade failures.
• Identify investigation strategies to evaluate the performance of remnant facade systems.
• Discuss best practices in design and construction to reduce the risk of failures and provide long-term performance.

Session Description

Facade systems serve several critical purposes, including establishing the architectural identity and providing protection from the elements. Often unbeknownst to owners, occupants, and the public, the condition of facade systems is frequently compromised due to deficiencies in the original design and construction, and/or deferred maintenance. Various factors contribute to the presence of these conditions including an inability to verify systems’ performance without performing hands-on surveys of elevated areas and challenges with completing destructive testing. Such conditions can lead to performance issues ranging from water leakage and isolated distress to detached cladding elements and collapsed facades that pose life-safety hazards. Although there are countless types of facade systems and causes of performance issues, select facade systems more commonly result in detachment. Understanding the limitations of these systems and components can help reduce future failures. Tailored for owners, property managers, architects, and engineers, this session will provide insights into preventing detachment and collapse of facade systems. Attendees will gain an understanding of facade systems that are more prone to failure and learn about strategies to mitigate potential failures. This session will also cover investigative and analysis strategy to evaluate the extent of failures and the performance of remnant facade systems.

Learning Objectives
At the conclusion of this session, participants will be able to:

• Identify potential issues that may arise due to inadequate project preparation.
• Recall examples where outside bias may have influenced initial thought processes.
• Illustrate how accurate historical research is crucial to understanding project complexities.
• Discuss real-world examples of project details/outcomes that have varied from initial assumptions.
• Recognize tools to help avoid preparation pitfalls that can hinder the successful completion of a project.

Session Description

In the building enclosure consulting profession, the simplest explanation is not always the best explanation. Building complexities can lead one to seek simple solutions but oftentimes issues are multifaceted, thereby requiring an “outside the box” approach.

It can be tempting to narrow one’s focus based on initial assumptions or other outside influences and the “simplest explanation.” However, diagnosing a building’s problems requires knowledge, experience, and historical perspective. When these tools are not used in tandem, achieving success may be prolonged.

In this session, the presenters will explore the concept of drawing conclusions before proper project preparation and illustrate how this practice can inhibit open thought and exploration. Audience participation will be solicited throughout the conversation.

Learning Objectives
At the conclusion of this session, participants will be able to:

• Articulate the case study of the historic slate assessment and repair.
• Explore material science research of slate and findings.
• Explain the methodology for critical evaluation of ASTM and international testing standards for slate.
• Discuss possible areas of growth in industry standards for predicting life expectancy for historic slate.

Session Description

Typical industry standard recommendation for slate replacement is at a 20% or more failure threshold. There are no field or lab tests that currently predict the remaining lifespan of existing weathered slate. However, ASTM C406 Standard Specification for Roofing Slate establishes the “grade” of new roofing slate, associated with projected life expectancy. Peter Meijer Architect PC sent slate samples to several labs to conduct C120 Standard Test Methods of Flexure Testing of Slate, C121 Standard Test Method for Water Absorption of Slate, and C217 Standard Test Method for Weather Resistance of Slate. These test results gave a gauge to the existing slate’s performance. A critical aspect of determining the life expectancy of archaic/older material is understanding the limitations associated with modern ASTM test methods. ASTM standards are not always accurate predictors of slate quality but are good sources of empirical data. Peter Meijer Architect PC used our experience and broadened our research into longevity by including testing means and methods from Europe and other countries with a longer history of slate testing. The standards in use on the market to certify slate are the British Standard Institute, BS EN 12326-1:2014, Slate and Stone for Discontinuous Roofing and External Cladding, and the United States ASTM C406.

Knowledge Level: Advanced
Recommended Prerequisites:

• Familiarity with the structure of the 2024 International Energy Conservation Code (IECC) and its compliance paths.
• Understanding of principles of thermal bridging including the concept of linear transmittance.

Learning Objectives
At the conclusion of this session, participants will be able to:

• List the prescriptive thermal bridging mitigation measures in the 2024 International Energy Conservation Code(International Code Council Inc., 2024)
• Discuss the application of linear transmission principles to demonstrate compliance with thermal bridging mitigation measures under the Component Trade Off and Total Performance paths in the IECC.
• Explore the usage of the Building Envelope Thermal Bridging Guide (Morrison Hershfield Limited, 2021) to look up the calculated linear transmittance for the key interfaces identified in the IECC 2024.
• Identify challenges posed by some traditional construction assemblies and the innovative systems that can help overcome them.

Session Description

A decade after the publication of ASHRAE 1365-RP detailing the impact of thermal bridging in envelope systems, the recently-adopted 2024 International Energy Conservation Code (International Code Council Inc., 2024) for the United States has introduced prescriptive requirements to address thermal bridging at key interfaces in the building enclosure. These prescriptive requirements are paired with linear transmittance values that can be used in the Component Trade Off compliance path and the Total Performance compliance path. This session will outline these new prescriptive requirements and associated linear transmittance values. Examples from the Building Envelope Thermal Bridging Guide (Morrison Hershfield, 2021) will be used to illustrate examples of linear transmittance for the key interfaces in this new code to provide examples of assemblies that can satisfy these new requirements. Examples of linear transmittance calculations will be used to demonstrate how some interfaces like the window to wall can dominate. The challenges this can pose in some traditional construction assemblies will also be presented as well as some of the innovative systems that can help overcome the limitations of these current assemblies by minimizing thermal bridging.

Learning Objectives
At the conclusion of this session, participants will be able to:

• Recognize the relationship between thermal bridging and condensation risk in typical clear field assemblies.
• Explain the difference between compatibility and proper adhesion.
• Understand the effects of thermal bridging and air leakage on typical clear field assemblies.
• Discuss the value of using thermal mass to reduce operational carbon and energy costs.

Session Description

The building enclosure industry is increasingly aware that we must reduce the energy demand and embodied carbon of new building construction. The building enclosure has become more complex than ever to design and construct to meet energy code requirements. In several states, code requires that the building enclosure must now meet mandates for air leakage and calculate thermal bridging losses. Moreover, stretch codes can require the enclosure to meet Passive House performance standards.  Additional attention to detailing, testing and inspecting are necessary during preconstruction to meet code requirements. Modeling may be required depending on the assembly Is the exterior, continuous insulation of our evolved wall designs truly continuous? How well an assembly will resist thermal conductive heat flow or potential condensation due to air leakage or vapor flow resistance is dependent on the materials and substrates we use in our designs. Compatibility does not guarantee good adhesion. Several typical facade assemblies will be analyzed for compliance regarding thermal resistance, hygrothermal performance (condensation control), and air leakage using modeling and laboratory testing.

Recommended Prerequisites: Baseline understanding of the following: precast concrete structural framing systems, types of precast concrete floor and wall systems, welded steel connections, masonry bearing wall construction; corrosion; load path; gravity; water leaks; field investigation, and evaluation of concealed conditions.

Learning Objectives
At the conclusion of this session, participants will be able to:

• Review the importance of maintaining the health, safety, and welfare of the building occupants and ensure that the appropriate testing takes place.
• Discuss the importance of putting facts and safety over politics and the wish to preserve comfort and limit disruptions for the owners, residents and guests.
• Identify the complexity of trying to put “Humpty Dumpty” back together again when the original 1970s-era design was lacking in vertical and lateral movement design accommodations and was absent any redundancy regarding the load path and water management design.

Session Description
Evaluation of an occupied six-story building with precast-concrete and masonry bearing wall structure, with no existing structural or architectural plans, required some creative thinking and a boatload of curiosity to get to the heart of the matter. Visual evaluation can take one only so far, and therein lies the lesson learned.   Partnering with a forward-thinking manager, our evaluation revealed layers and layers of information that brought us to the “uh-oh moment” when we exposed the following:   Failing welded precast spandrel panel-to-precast concrete column connections, disengaged precast concrete embedment plates and severe column damage along with severe concrete cracking/distress. Deteriorated conditions required shoring, occupant disruption and some creative contractor-engineer collaboration to stabilize, re-support and realign a failing enclosure system.

Learning Objectives
At the conclusion of this session, participants will be able to:

• Discuss the multifaceted cause of roof failures, including the critical role of penetrations and of flashing.
• Identify signs of poor drainage and inadequate detailing, and their implications for the durability of the roof.
• Explore effective strategies for the integration of roofing systems within the broader building envelope.
• Recognize that the effects of climate change, such as higher precipitation levels, enhance the risk of roof failures.

Session Description

This presentation will provide insights on forensic failures of roofs and how, given the changing climate and higher precipitation levels, these forensic failures are becoming more prevalent. Roof failures are a complex phenomenon that is primarily attributed to construction and design inadequacies. Deficiencies in roof detailing facilitate water entry, undermining the roof’s structural integrity and causing leaks and interior damage. Flashing issues, stemming from poor installation or maintenance, lead to water leakage at critical interfaces such as penetrations. Design flaws such as inadequate considerations for load distribution, water management, and adaptation to the local climate can lead to catastrophic outcomes. The inadequate integration of a roof with the broader building enclosure can also exacerbate these problems. These issues highlight the intricate challenges associated with roof failures, emphasizing the critical need for well thought out design and construction of roof features.
