This presentation initially took place at the 2020 Convention. New construction and renovation projects provide their own set of unique challenges, especially during the installation and integration of new fenestrations systems (e.g., sliding glass doors and windows). The focus of this paper will seek to analyze both similar and distinctive modes of water penetration failure that have been observed during multiple sessions of water testing performed in general accordance with accepted industry standards. This paper will further analyze and discuss the water testing failures related to detail design and constructability issues associated with work performance and project management, using several case studies. Applying the learned knowledge of water penetration failures during the design and installation of fenestration systems of new or renovation projects will lead to improved performance and life expectancy of the building enclosure as a whole. Wayne Butler, AIA Applied Building Sciences, Inc. | North Charleston, SC Wayne Butler’s architectural design practice focuses on building enclosure design, consulting, and diagnostic testing for a variety of architectural projects. The emphasis of his work has been in the hot/humid, high-wind/high-seismic zone of the Southeast. Wayne received both his B.S. and masters in architecture from Clemson University. Wayne is past chair and current board member of the Building Enclosure Council|Charleston, served on the Building Enclosure and Environmental Council – BETEC Material & Innovation Committee, is an active voting member of ASTM E06, Performance of Buildings, and a board member and mentor with Architecture, Construction, and Engineering’s (ACE’s) Mentor Program of America (Charleston Affiliate). John C. Wylie, REWC, PE Construction Science and Engineering, Inc. | Westminster, SC John C. Wylie has over ten years of experience as an engineering consultant and engineering intern, primarily in the areas of deficient construction, structural analysis, and collapse/damage investigations. Wylie is licensed as a professional engineer in four states and a Registered Exterior Wall Consultant with IIBEC. He is responsible for the inspection and structural analysis of a wide variety of building enclosure and framing systems, including roof, wall, and guardrail systems. Wylie has provided deposition testimony during a litigation case, and has presented several technical papers at national and regional conferences. He is a member of IIBEC’s Interface Editorial Board.

This presentation initially took place at IIBEC's 2022 International Convention and Trade Show in Orlando, Florida. Standing seam roofs (SSRs) behave somewhat differently than other roof coverings when exposed to wind uplift pressures. Their design came under closer scrutiny after Hurricane Andrew struck south Florida in 1992. Since then, our knowledge of SSR wind resistance has increased considerably, such that SSRs can now be properly tested, designed, and installed to meet relatively high wind design pressures, including in perimeter and corner roof areas.    This presentation explains that external seam clamps or wind clamps can substantially increase the wind uplift resistance of an SSR if they properly fit the seam profile and are installed correctly. They may change the failure mode of the SSR, and the limiting factor of the enhanced assembly will likely be the strength of the internal clip. When securing solar panels to an SSR, it is important that the clamps used to secure them be attached to each deck rib to follow the wind load path of the SSR design and prevent overloading internal clips Richard J. Davis, PE FM Global | Manomet, MA Richard J. Davis has been working in loss prevention engineering for 47 years. He has written and revised a number of FM Global data sheets on construction, including the ones for standing seam roofs and roof-mounted solar panels. Davis has also served on many external committees working on codes and standards development, including the ASCE 7 wind load subcommittee for the last three revision cycles. He was task committee chair for the chapter on roof-mounted equipment during the latest ASCE 7 revision, and he contributed to the 2017 revision of the Structural Engineers Association of California’s Wind Design for Solar Arrays (SEAOC PV2). Davis has given numerous presentations on wind design, both internally for FM Global wind specialists and externally to various roofing associations. Read More

This presentation took place during the 2020 Region V Meeting. Window replacements and retrofits represent a significant investment, and, therefore, it is key to decide on the right strategy and to provide the owner with accurate information on performance and options. Before you replace or retrofit windows, many factors need to be carefully evaluated. The most important first step is understanding the owner’s reason for wanting to replace or retrofit windows. For example, if improving sound control is the primary reason, then glass selection for the new window or a retrofit storm sash are the critical factors to consider. If water intrusion is the main complaint, then it is critical to understand whether the water intrusion is related to the window only or the surrounding wall claddings or flashing. The second most important step is evaluating the existing conditions of the windows and its integration and flashing with the surrounding wall claddings. These first two critical steps will then help you advise the owner on appropriate replacement and retrofit strategies and options, which include window types and installation options. This presentation will cover this evaluation, design, and installation process and explain several key energy efficiency upgrades that can be considered at the time of window replacements for low incremental cost. This presentation will also show example case studies of what can go wrong when these steps are not followed. Learning Objectives: 1. Identify the owner’s reasons for window replacement or retrofit, including whether to address water intrusion, condensation, air leakage, thermal comfort, energy performance, functionality of window sizes, aesthetics, acoustics, or security. 2. Describe the steps in a condition assessment to determine performance of existing windows and the integration with surrounding wall claddings and flashings. 3. Summarize window replacement and retrofit options, including punched windows, ribbon windows, reglazing options, and installation options. 4. Explore with the owner energy efficiency retrofit options for both windows and surrounding claddings that can be performed at the time of window replacement for low incremental cost Joe Piñon, PE RDH Building Science Inc., Oakland, CA Mr. Piñon has an advanced degree in building science and has accumulated extensive experience on how buildings and façades perform, both from his practical research and testing on how walls get wet and dry, and from his design and investigation experience. He works with architects, contractors, developers, and owners to help achieve cost-effective, durable, watertight, and energy-efficient building enclosures. Joe has presented many of his published works and best practices at conferences all over the country and at client and manufacturer training sessions. Megan Cross-Wilkinson Megan Cross-Wilkinson is an associate, building science engineer in the San Francisco Bay Area with 8+ years of experience. She works on new construction, existing building rehabilitation, and forensics/litigation projects. Her experience ranges from façade design for high-rise unitized curtainwalls to large re-cladding projects for existing wood-framed structures. She has worked on construction projects in a variety of geographic locations, including California, British Columbia, and Ontario, Canada.
