This presentation was initially provided at the 2021 Convention in Phoenix, Arizona.  There have been significant developments in methods to quantitatively evaluate building enclosure thermal bridging. While these tools are available to the industry, it is apparent that many project teams do not know how to efficiently incorporate thermal bridging analysis as part of project design. As project teams are incorporating target value design and lean principles through an integrated project delivery, a thermal bridging analysis can bring huge value to the project. An effective analysis quantitatively identifies thermal performance and condensation risk, while working with the project team to determine the most cost-effective approach to meet the project goals. The thermal analysis can be reconciled with the owner’s project requirements, energy modeling, and HVAC design to realize the full value. This presentation will summarize the technical aspects of thermal bridging while using case studies to show how the process is used effectively to achieve maximum value.

This presentation was initially provided at the 2021 Convention and Tradeshow in Phoenix, Arizona Continuous Insulation presents challenges with the overall wall assembly’s design, performance, and construction. This second of two programs at the advanced level utilizes eight commercial steel-framed wall assembly designs to evaluate their comparative differences while standardizing to an NFPA 285-compliant assembly under ICC 2018 in Climate Zone 5 (due to the requirement for an interior vapor retarder). The evaluations of the eight assemblies begin with an overview of their components with their assembly’s benefits and challenges. This overview includes describing the rationale for the choice and location of the continuous and total insulation, sheathing (if any), weather and vapor control layers, and the concerns for condensation management and thermal breaks. The eight are then compared for their NFPA 285 compliance, and then evaluated by their WUFI hygrothermic modeling over four climate seasons. They next are evaluated for their structural cladding load and wind-load resistances, and finally, they are comparatively ranked by cost of construction and speed of production. Rather than focusing on the benefits of one construction material or assembly, this program weaves together eight different entire wall assemblies to compare and rationalize. The presentation utilizes 3-D modeled imagery to help visualize their integrated assemblies.   G. David Schoenhard, RRO, AIA, BECxA, CSI, LEED AP DSS-Philly | Narberth, PA G.

This presentation was initially provided at the 2021 Convention in Phoenix, Arizona Adhered masonry veneer (often referred to as manufactured stone veneer, or MSV) has been growing in popularity and use throughout North America over the past 20 years. MSV offers the beauty of masonry with the cost efficiency and reduced weight of stucco. In addition to specific manufacturers’ instructions, current codes and industry standards that govern its design and installation include ICC-promulgated model building codes, masonry codes (TMS 402 and TMS 602), ASTM standards, and Masonry Veneer Manufacturers Association (MVMA) publications. Simply referencing these published code and industry-standard documents in drawing notes, project manuals, or contracts is often insufficient, leading to improper design and installation techniques that ultimately result in failure. This paper presents some of the common design and installation pitfalls associated with MSV to help designers and installers enjoy a more successful, durable application. This presentation is targeted at an intermediate audience of designers, installers, and building owners.

This course was initially presented at the 2021 International Convention and Tradeshow. Architecture students need individualized support from faculty and mentors to learn about building enclosures in preparation for internships and practice. While challenging in the best of times, imparting this knowledge is even harder during a pandemic. In this intermediate-level presentation, the speaker will recount the process and outcomes of the IIBEC Mid-Atlantic and Virginia Chapters Student Design Competition held at Virginia Tech’s School of Architecture + Design (SA+D) immediately after the shift to online learning in March 2020. Surprisingly, this seventh competition of its kind produced the most detailed work yet. This result is likely due to the unprecedented dedication of IIBEC members serving as mentors and jurors; the individual attention afforded to each student; and the pointed interaction of students and mentors through the marking up of drawings in real-time. Final student submissions will be shared, along with insights gleaned from the mentoring sessions. While the SA+D values self-directed learning, the students’ overarching conclusion was that they greatly benefited from the specific input on their design projects, representing knowledge that they would not have otherwise gained in school. These insights will be of interest to building enclosure consultants, emerging professionals, and IIBEC chapter leaders looking to initiate similar student competitions as service and outreach.

This was initially presented at the 2021 International Convention and Trade Show.  Water damage is the number one cause resulting in lawsuits against builders. In the spring, the roof leaks, but it has not rained for months. Where is the water coming from? I used high-permeable materials in the building construction, so why do I have moisture problems? I have been constructing buildings for decades; I never had a moisture problem in the past, so why am I getting them now? This presentation shows the ways that moisture moves in the building and why moisture problems are showing up in today’s construction. The energy and moisture transport calculator is used to provide some of the answers to these questions. Laverne Dalgleish Laverne Dalgleish has spent most of his life in the construction business.

This course was initially presented at the 2021 International Convention and Tradeshow. The Federal Emergency Management Authority (FEMA) deployed Mitigation Assessment Teams (MATs) after Hurricanes Irma and Michael impacted Florida in 2017/2018. The MATs included participation from industry, academia, regulators, insurers, and other interests. The teams were deployed in affected areas after the storms to study wind damage, report observations, and make recommendations on how to improve construction methods and help reduce the chance of damage from future storms. This presentation will provide a review of the recommendations from the MAT reports and show how high winds can impact construction. It will include consideration of wind damage to roof assemblies, as well as water damage to structures and contents resulting from wind-driven rain, and will focus on the specific recommendations from FEMA as well as the roofing industry response.   Aaron R.
