This course was initially presented at the 2021 International Annual Convention and Tradeshow Continuous air barriers are required by the energy code to reduce the overall energy consumption of a building. Air barriers also have benefits beyond energy savings and contribute to long-term enclosure durability by preventing significant condensation from air leakage. This paper discusses code development updates, design-based applications, construction best practices, and provides a roadmap with real-world examples for continuous air barrier strategies to achieve performance in building design, construction, and operations. Recognizing that materials often serve dual functions to contribute to the continuous air barrier is key to success—such as roof system vapor retarders that are part of the air control strategy, as well as roof membranes designed as part of the air barrier tie-in to the wall below. This presentation will review key enclosure interfaces, including the roof-to-wall connections, parapets, and transitions between enclosure assemblies. Construction quality assurance and performance testing for owner acceptance are important steps to ensure the design intent is delivered onsite. With regard to air barriers, this presentation discusses the impacts of whole building performance, design requirements, material and assembly requirements, and installation verification requirements during construction. It will provide expert-level insight into the current energy code development process and experience from field observations. James R. Kirby, AIA James R. Kirby is a GAF building and roofing science architect with a masters of architecture (structures option) degree. He has over 25 years of experience in the roofing industry covering low-slope, steep-slope, metal, SPF, vegetative, and rooftop photovoltaics. He understands the effects of heat, air, and moisture on a roof system. Kirby presents building and roofing science information to architects, consultants, and building owners, and writes articles and blogs for building owners, facility managers, and the roofing industry at large. Kirby is a member of AIA, ASTM, ICC, IIBEC, NRCA, and WSRCA.   Benjamin Meyer,  AIA, NCARB, LEED AP Benjamin Meyer is a building and roofing science architect with GAF.

This presentation initially took place at IIBEC's 2022 International Convention and Trade Show in Orlando, Florida. The American Society of Civil Engineers ASCE has updated the wind design provisions in the 2022 edition of ASCE 7. Many of the provisions aim to simplify the use of the component and cladding design provisions, particularly in determining roof zoning and design pressures. The presentation reviews these revisions and discusses the reasons for eliminating the tabular methods, the basis of the new tornado design provisions, and updates to the wind speed maps. Donald R. Scott, PE, SE, FSEI, FASCE PCS Structural Solutions | Tacoma, WA Donald R. Scott is a senior principal with PCS Structural Solutions. He has nearly four decades of experience in the design, evaluation, and rehabilitation of building structures. He was the principal investigator for the American Society of Civil Engineers/Structural Engineering Institute (ASCE/SEI) Prestandard for Performance-Based Wind Design. Scott is chair of the SEI Codes and Standards Executive Committee, chair of the ASCE 7 Wind Load Subcommittee, member of the ASCE 7 Main Committee, and past chair of the National Council of Structural Engineers Associations’ Wind Engineering Committee.

IIBEC is proud to partner with the U.S. Department of Energy for the Better Buildings’ Building Envelope Campaign! The campaign is an opportunity for building owners to save energy and money by recognizing the role a high-performing building envelope plays in an energy-efficient building. In this webinar, you’ll get an introduction to the campaign and be part of an interactive discussion about the new building envelope performance metric and the corresponding assessment tool. This campaign is ongoing and open to new participants. Read more

This webinar will discuss select rated roofs and edge metal systems as well as establish roof zone layouts based on prescriptive and performance methods. A discussion of the new code requirements and compliance tools regarding ASCE 7-16 will also be covered. Learners will be able to immediately put their learning into practice, as they will be placed on a project team to work through a wind uplift design.   Speaker(s) Information: Kristen Westover and Jennifer Keegan, AIA | GAF Materials Corp.

These 5 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:  Recertification Resurgence—Mitigating Risk in our Nation's Older Structures Building Codes- Implications for Repair of Buildings and Building Enclosures Building Fire Safety: No Singular Solution, It Takes a Village Historic Industrial Building Reuse and the Building Enclosure Six Frequently Misunderstood Topics Related to Commercial Building Enclosures Read more

An enclosure that is appropriately responsive to its environmental loading conditions is one of the most fundamental measures of satisfactory performance for the built environment. Some loads are directly experienced by enclosure components and materials themselves, while other loads are experienced because material deformations or deflections influence those components and materials. While the relationship between structural movement and a structure’s usefulness to its intended purpose has been well understood throughout the history of design and construction, that understanding has not always translated well into satisfactory enclosure performance. Drawing on experiences in post-construction forensic investigations, troubleshooting during construction, and efforts to influence design detailing, this presentation will discuss key factors in applying engineering mechanics for the benefit (or detriment) of enclosure performance. Specific aspects to be shared will include the cross-party dynamics in design and construction that give rise to current challenges, case studies of failures as a result of insufficient consideration, and areas for improvement across the design and construction industry.
