This topic was initially presented at the 2021 Virtual Spring Symposium Presenters: Thomas Smith, AIA, RRC, F.SEI and Scott Bondi, Ph.D., P.E. (NY, CT, NJ, PA), LEED AP ASCE published the Prestandard for Performance‐Based Wind Design (PBWD) in August 2019. It presents a recommended alternative to the prescriptive procedures for wind design of buildings contained in ASCE 7 and in the International Building Code (IBC). PBWD provides the ability to gain structural economy through enhanced analysis and design techniques. PBWD is intended to rationally reduce damage and losses for design wind effects. Performance objectives are established at the onset of design and are measured according to their related acceptance criteria. The Prestandard concentrates on the structural systems of tall buildings. However, Chapter 8 presents enhanced design criteria for the building envelope. The criteria address envelopes of both high-rise and low-rise buildings. Chapter 8 is intended to advance the performance of building envelopes. The presentation will provide an overview of the performance-based wind design of structural elements. However, the presentation will concentrate on the building envelope criteria given in Chapter 8. In addition to design criteria, the construction contract administration and post-occupancy inspections, maintenance, and repair will be discussed. The presenters of this proposed presentation were the authors of Chapter 8.

Polyvinylidene fluoride (PVDF) coatings have been a reliable part of construction since the 1960s, but over the past 15 years, we have witnessed an increasing number of premature PVDF coating failures. This paper will review changes the industry made that led to these failures and how to avoid them through proper specification and testing. This presentation will demonstrate that the failures can be attributed to changes in the industry’s use of chromium phosphate pretreatment wash—the tried and true method. The American Architectural Manufacturers Association’s specification AAMA 2605 initially included chromium phosphate wash as a mandatory requirement. However, because there are concerns about the environmental impact of chromium, manufacturers’ use of the wash became voluntary in 2004. Alternate washes such as phosphoric acid are being used instead of chromium phosphate, leading to poor adhesion and a lack of corrosion protection. This paper will also review the steps and costs involved in repair and recoating procedures, and how to modify technical specifications and implement testing to mitigate premature failure.

 This is a 16-hour course classroom extension of the IIBEC Manual of Practice. It provides an overview of consultant roles that are unique to the roofing, exterior walls, and waterproofing industry. The course also identifies the consultant practices that are common to these three broad disciplines. The course examines building enclosure consultants and discusses what they do and how they do it and is a recommended foundation course for becoming more specialized. Read more

Design solutions must be buildable in the real world. Façade design intent, geometry, and materials must come together in a way that allows structural loading, environmental protection, and optimal long-term performance. Performance mock-ups bridge the gap between conceptual design and construction and allow project teams to test expectations and fine tune the plans prior to installation. This step is particularly important with innovative façade designs that incorporate new materials or complex integrations between various standard assemblies. A performance mock-up is commonly understood as a tool to test previously untested cladding and glazing assemblies. However, it can also be a valuable tool for understanding constructability, sequencing, and integration detailing. Transition detailing, in particular, is unique to each project, and while the design may include transition concepts and shop drawings may be carefully detailed, getting the systems to work together can be a challenge and result in unintended design changes, as well as schedule and cost impacts during construction. In this presentation, we will explore how performance mock-ups translate design intricacies into constructible assemblies, and ultimately, a successful project. We will discuss laboratory and on-site mock-ups and how to make the most of each, including strategies for planning, timing, testing, and follow-through Ryan Upp Simpson Gumpertz ​&​ Heger | Los Angeles, CA Ryan Upp is a senior project manager in the Building Technology Division of Simpson Gumpertz ​&​ Heger’s Los Angeles, CA, office.

 Reroofing Course Description This 6-hour course covers a range of concepts, including a discussion of the steps required for the roof consultant to successfully evaluate an existing roof and to make decisions regarding roof design using available references, resources, and evaluation techniques. Speakers will present a review of reroof options and decision-making principles, building code considerations, reroof considerations, and examples of roof systems. Proper preparation of plans and specifications is presented to clarify the delivery of these documents. The roles of the stakeholders in the bid process are discussed.  This course examines the elements required to properly execute meetings, project site visits, design resolutions, and project closeout.   This course is designed for building consultants, architects, and engineers who regularly engage renovation of existing buildings (schools, office buildings, industrial buildings. etc.) Course Access Courses are accessible in LearnUpon for one year from the date of purchase.

This presentation initially took place at IIBEC's 2022 International Convention and Trade Show in Orlando, Florida.  How do you make sure penetrations through your already installed air and water barrier are watertight? The method of sealing of cladding attachments through the wall assembly are critical to the building performance. To create a relevant, data-backed solution, a robust test plan was developed using a statistical test design and implemented to test all the variables of interest. Then, a statistical model was built to predict the probability of leaks with various sealing solutions. The process was used to determine which type of flashing and sealing solution is best to ensure watertightness after cladding attachments are installed over polyisocyanurate insulating sheathing. This presentation shares the basis of the test plan and research methodology as well as the findings on sealing penetrations through this system.   Andrea Wagner Watts, LEED Green Associate DuPont Performance Building Solutions | East Aurora, NY Andrea Wagner Watts is the commercial application leader for DuPont Performance Building Solutions.
