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. Focusing on building sciences, Maziyar Bolour is a senior project manager and leads Walter P Moore’s Diagnostics Group in Toronto, Ontario, Canada. Having joined the architecture, engineering, and construction industry in 1997, he is experienced in structural design, evaluation, and rehabilitation of building structure and enclosure systems. He has completed more than 100 detailed condition assessments and technical audits for insurance companies, private property owners, and developers, and routinely performs audit and condition assessments of existing structures, parkades, and window or curtain wall systems commonly used in North America. Bolour’s extensive knowledge of the National Building Code of Canada /Ontario Building Code and the related design standards for various construction materials, along with a combination of structural engineering and enclosure consulting expertise, have made him an excellent resource for any complex repair and restoration project.

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.

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.
