The building enclosure design is an important element in all project construction types but is elevated more when considering the use of Mass Timber. In the Southern US region, the learning curve is high androject examples are low for Mass Timber. Two projects in the Houston area have experienced high rain levels and even a rare snow storm event during construction. These weather events have brought to the forefront the many challenges that exist in building a project constructed of wood in this wet weather climate. The typical construction with steel and concrete does not take into account the need to allow for rain water to be alleviated during construction. These lessons learned have created new responses that allow for water to be quickly removed off the CLT deck and all the pow for quick, noncombustible envelope installation. Therefore, the building dries out faster, providing a better working environment for the remaining installation trades.

Adapting to Changing Conditions, Innovations in the Building Envelope: Technical Innovations, Adapting to Changing Weather, and Disclosure Requirements Related to Climate Change Performance

Building materials enable architecture, and innovation can test the strength of historical materials selection processes. For example, architectural innovation may require that plastics and polymer composites be subjected to operational requirements that were not as relevant to prior designs. As a result, traditionally successful materials may be subjected to not fully anticipated conditions during their development and testing. This presentation will explore instances where architectural innovation has resulted in materials functioning beyond the tested requirements. The examples include cold warping of insulated glass units (IGU), incidents of sealant failure in IGUs, and finally, how testing methods and models can be adapted from these examples to match the pace of innovation in architectural design.

The evolution of outcome-based performance criteria in the building & construction industry is placing more emphasis on the traditional ways of addressing air and water tightness. There is such a strong correlation between energy performance of commercial buildings and the management of uncontrolled air infiltration that we have seen Energy Codes (e.g. ASHRAE 90.1) and select jurisdictions adopt requirements to show a continuous air barrier systems in the construction documents and to demonstrate compliance of the construction through testing. As a way of measuring this performance criteria, the industry has seen a rise in whole-building air leakage testing.

The design of the building, the selection of the appropriate material, the awareness and means of addressing key interface details are pivotal in a successful whole-building air leakage test. With enhanced air-tightness requirements in the State of Washington Energy Code, this course will explore the paths that two recently completed projects took to achieve its air-tightness performance goals through a method paralleling that of the Building Enclosure Commission (BECx) process.

Focus will be on the on aspects of building enclosure detailing, installation, and material selection and their specific performance capabilities that enabled the building enclosure system to ultimately demonstrate how they positively impact the whole building air-tightness performance and verified through whole building air tightness testing. The financial implications of the BECx–inspired process, and its associated testing, will be discussed in the context of the overall benefit the process brought to the project.

Building codes are evolving to create more stringent standards for energy efficiency. Passive techniques were used in building design for centuries to help moderate indoor temperatures before heating and cooling systems become prevalent. Now, passive techniques are making a resurgence because of their effectiveness in achieving ideal indoor environmental conditions. Join us to learn about passive techniques that meet energy codes, including thermal mass, proper day-lighting, and thermal bridging. Hear lessons learned from real-world projects that incorporate passive energy techniques.

Over the course of its history, Architectural Aluminum Framing Systems have grown and multiplied to meet the changing demands of building envelops. This industry started by meeting the demand for a sustainable storefront solution in the early 1900’s. Today architects are faced with selecting from a wide range of system options. Two major types of framing systems are Storefronts and Curtain Walls. In some cases, these systems could occupy the same space but in others, selecting the wrong system could have harmful consequences.

This presentation focuses on the characteristics that distinguish these two systems. This describes how each system is assembled, how they handle water, thermal characteristics, and structural differences. The goal is to give you a good understanding of the differences between these systems and the appropriate application of each. You will have a clear understanding of why a storefront should not be used where a curtain wall is needed and be able to explain this to others.

Adhered masonry does not meet code because seismic testing does not exist in our industry; until now. There are a few common examples where a "Standard of Care" is met without meeting Code in common built solutions. 3 years worth of testing finished April 2023. This presentation summarizes the results and how to apply to your building. The process of adding information to the "Field of Knowledge" will be explored.

By now, design and construction professionals are well aware of the significant impact of buildings on the natural environment. That fact is even more prevalent as evidenced with the ever increasing thermal performance provisions in our codes and standards. While the industry has become adept at throwing more and more insulation at these challenges, there are a few exciting insulation technologies, and creative ways to deploy them, than many enclosure professionals may realize.

This presentation will discuss how these options, in the forms of new insulation materials providing designers with more aesthetic leeway in attaining elevated performance levels. Detail-driven dives will also demonstrate how clever approaches to design and construction, as well as innovative detailing strategies, can be leveraged to accomplish these thermal performance goals without sacrificing design intent.

As we move toward higher performance buildings supported by advanced technologies, we require more advanced tools to not only analyze but also disseminate the information. This session will use data driven guidance and highly visual tools to communicate a more complete picture of whole building energy performance. The frameworks presented will highlight the relationships between multiple performance variables, allowing designers to make more informed decisions and building energy policy makers to focus attention on areas of higher priority. The session will include a brief overview of the recently published Building Envelope Thermal Bridging Guide (available publicly, free of charge), followed by a “how-to” use the guide, using building case studies and hands-on examples. The exercise is meant to teach participants how to use the guide, but also to understand the implications that the information has on opaque building envelope performance.

The second part of the session will introduce the concept of building energy performance mapping (BEPM) using unique visualization techniques. With a case study as a backdrop, we will explore how the use of BEPM can put into context building performance characteristics, such as thermal bridging and wall R-values in comparison to glazing, architectural massing and other parameters. Highly visual tools will be used to consolidate vast amounts of data into a package, allowing architects and designers to make informed decisions throughout design without relying solely on, or waiting for, project-specific calculations. The ease at which BEPM helps visualize results makes it accessible to all designers, allowing this part of the presentation to be highly interactive.
