IIBEC Online Education

This presentation initially took place at IIBEC's 2022 International Convention and Trade Show in Orlando, Florida. This presentation describes a testing and research project to determine how the bond capacity of low-rise foam adhesive between insulation panels at varying adhesive ribbon spacings was affected when the adhesive was applied to both fiberglass and organic-faced polyisocyanurate insulation boards. The project scope included design and fabrication of custom 4-ft× 4-ft aluminum frames; testing of eighteen 4-ft square specimens in direct tension until failure; testing six companion, small-scale (12 in. × 12 in.) specimens in direct tension until failure; evaluation of test results; and development of key observations from the test program.

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.

This presentation initially took place at IIBEC's 2022 International Convention and Trade Show in Orlando, Florida. Despite its many benefits, continuous insulation in exterior wall systems separates the cladding from the supporting structural framing (often by 2 in. or more), which can create severe demands on fasteners bridging the gap. Connection details become increasingly challenging to reasonably resolve demands and capacities, particularly with heavier claddings and thicker continuous insulation. The industry has responded to some degree: designers are being more creative, suppliers are developing proprietary thermally improved framing or clip systems, and model building codes recently incorporated fastening requirements. However, the industry has not fully addressed the complex array of conditions that can be encountered and the associated engineering issues to efficiently provide proper performance of the exterior wall system. This presentation discusses the complex behaviors of the seemingly simple cladding connections through continuous insulation, associated design challenges, concepts for resolving demands and capacities, and current requirements recently adopted in the International Building Code.

This panel discussion of industry leaders and manufacturers will provide learners with a better understanding of how the supply chain crisis is impacting manufacturers and building enclosure consultants. A discussion will take place on how building enclosure consultants can work with manufacturers to determine appropriate workarounds while ensuring they do not violate warranties. Read more

Recent changes in building energy codes include enclosure criteria that minimize building enclosure thermal loads and, in turn, reduce a building’s energy consumption. These changes require modifications in traditional building enclosure designs to meet evolving energy code requirements. Unfortunately, some energy-efficient designs, while code compliant, may adversely impact a building’s durability. The minimum requirements in green standards alone, such as LEED, Green Globes, and IgCC, may lack comprehensive measures to ensure long-term durability of the enclosure assemblies. Optional and required credits included in green standards are beginning to address moisture durability and, in this paper, are compared regarding the scope and impact of the building enclosure across the project phases: • Material selection • Design and procurement • Construction activities • Performance testing • Operation and maintenance • Enclosure commissioning This paper reviews various aspects among the green standards, including gaps and similarities in the rating systems, and strategies to utilize the best parts of each rating system to improve project performance related to moisture durability. Detailed roof system examples will also be provided demonstrating how these measures can enable energy-efficient and durable enclosure assemblies.

This course was initially presented at the 2022 International Convention and Trade Show in Orlando, FL.  In recent years, nondestructive testing (NDT) methods have evolved as important tools for assessing both building enclosure and structural components. At the same time, many practicing engineers and architects are unaware of these methods or their capabilities. This presentation covers selected NDT methods that are currently in use in North America, and it includes a case study for each method presented to demonstrate how the NDT investigation guided the design team to an appropriate repair strategy. Attendees will gain an overview of select techniques for potential use in assessments.
