IIBEC Online Education

This course was initially presented at the 2021 International Convention and Tradeshow. 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.

The design, installation, repair, or retrofitting of a metal roof is a complex process that requires skill and patience. The first segment of this presentation will provide learners with a better understanding of the different types of metal roofing, testing practices, and site conditions that are not always a one-size-fits-all when determining the manufacturing process of the metal roof. In his second and third presentations, our speaker will share his wealth of knowledge regarding metal roofing and provide the learners with invaluable tips and tricks relating to design installation, repair, or retrofitting metal roofs.   Read more

Bundle Overview These 3 sessions were originally presented at the 2023 IIBEC International Convention & Trade Show in Houston, Texas.  The courses include the recording of the session, a summative assessment consisting of 10 multiple-choice questions, and surveys required to claim continuing education credit. The bundle includes the following courses:  Drone-based 3-D Photogrammetry in Building Enclosure Consulting Practice Introduction to LiDAR and Its Uses in Building Enclosure and Beyond Eye in the Sky: Mitigating Facade Access Risks Through Unmanned Aircraft System Aerial Imagery Read more

Flanged windows are typically considered a product for low-rise residential buildings, and un-flanged window systems (curtainwall, window wall, storefront) are typically considered products for commercial and high-rise construction. However, a new type of window system is becoming more common on high-rise construction: flanged, aluminum windows designed for high-rise buildings. While numerous industry standards exist to guide the installation of flanged windows in low-rise construction, virtually no guidance exists to inform best practices for the installation of higher-performance flanged windows in high-rise construction. Terracon Consultants, Inc. and JE Dunn Construction partnered in 2017 to perform water penetration and air leakage testing of flanged window details, which resulted in a chapter in the ASTM publication entitled Whole Building Air Leakage: Testing and Building Performance Impacts Manuscript ID STP-2018-0028.R4. While valuable conclusions resulted from that collaboration, the team was limited in their testing capability. Therefore, Terracon and JE Dunn have now partnered with Tremco to expand upon our previous research efforts. Tremco has a large, sophisticated testing facility in Cleveland, OH, that can provide more accurate and a much greater quantity of tests. This research and collaboration effort regarding window details is part of a greater effort to establish a high-rise detailing manual badly needed by our industry.   Keith Simon, AIA, CPHC, LEED AP, BECxP Terracon | Austin, TX Keith Simon joined Building Exterior Solutions, Inc.

This presentation initially took place at IIBEC's 2022 International Convention and Trade Show in Orlando, Florida. Water Tower Place is a 74-story building constructed in 1976. The exterior facade is generally constructed of 1½-in.thick Georgia Cherokee Solar Gray marble stone veneer panels, with flush aluminum-framed windows. The panels are typically restrained using stainless steel kerfs at the bottom corners or center of the panels, and stainless steel pins at the top and sides of the panels.  In December 2003, the owner was advised that bowing of the marble facade panels and presumed accompanying marble strength loss had accelerated after 25 years of slow but linear weakening—the marble had lost 30% of its strength in roughly 30 years. This presentation reviews efforts to extend the facade’s service life to 2025 or longer. After hundreds of strength tests were evaluated and an updated wind tunnel test was performed, nearly 17,000 custom repair anchors were installed in the building from 2007 through 2009. In the years since then, additional yearly examinations have been performed, along with additional stone testing. The repairs implemented nearly 20 years ago have kept the facade serviceable, and the future serviceable life is currently being studied. William D.

This presentation initially took place at IIBEC's 2022 International Convention and Trade Show in Orlando, Florida. New research and building code provisions have improved appropriate means to continuously insulate walls and integrate fenestration in punched openings for optimal performance. This presentation reviews structural wind resistance and water-resistance research supporting various detailing options in the context of new provisions in the latest editions of the International Building Code and International Residential Code. The presenter also discusses the thermal efficiency and thermal bridging implications of various details to integrate punched openings with continuous insulation on walls. In addition, the presentation includes a sneak-preview of new research on wind-driven rain hazard characterization as a means to improve guide design and detailing decisions for water-resistance of building enclosures and components.
