Used appropriately with other control layers, the thermal control layers (insulation) of a cold-formed steel wall assembly can actually contribute to improved durability and energy efficiency. This presentation looks at five key building science topics together with new code requirements and design tools to help navigate and coordinate building code requirements for moisture control and energy code requirements for insulation.
The presence of an airspace enclosed within a building envelope assembly is known to contribute to the overall thermal performance of the assembly. But, the actual R-value of an airspace can vary significantly depending on various conditions of use, such as the air-tightness of the assembly of materials enclosing an airspace.
This presentation reviews structural wind resistance and water-resistance research supporting various detailing options in the context of new provisions in the latest editions of the IBC and IRC.
Presented as a live, full-day course at the 2022 Colorado Chapter of ICC Educational Institute, Jay Crandell, P.E. and Thomas Culp, Ph.D. cover the importance of the building thermal envelope in the context of the 2021 International Energy Conservation Code.
Newer homes, materials and code requirements have changed the way “invisible” water (water vapor) must be managed to avoid it becoming visible in unwanted ways. Water vapor control is one of the trickiest and riskiest areas of building and energy code compliance. The old “rules of thumb” are no longer reliable or universal. This program, originally presented at IBS 2017, provides actionable prescriptive guidelines for integrated insulation and vapor control strategies.

This updated presentation reviews the research and latest prescriptive code requirements for attaching claddings through a layer of exterior continuous insulation.
Building code requirements relating to NFPA 285 testing requirements and the use of the alternative materials provision of the code to extend those test results to similar wall assemblies of equal or better performance.
This presentation covers representative solutions for integrating windows with foam plastic insulating sheathing (FPIS).
Overview of key building science concepts, U.S. & Canadian code requirements, accepted methods of design to control water vapor, and design solutions for all climate zones and walls with or without continuous insulation.
Stop Wardrobe Malfunctions: Don't Eat Your Sweater: Continuous Insulation for Code-Compliant & High Performance Walls
Contains resources on using continuous insulation for compliance with the building codes and energy codes.
Summary of WRB water penetration testing requirements and recommendations for the fair treatment of WRB products based on one performance-based benchmark for water-penetration resistance of WRB assemblies.
This presentation addresses two practices with proven ability to improve water penetration resistance of fenestration product installation: Sill pans and flashing for rough opening drainage, and air-sealing of the interior side of the rough opening gap.
Thermal bridging can significantly impact whole building energy use, condensation risk, and occupant comfort. This presentation contains an overview of the various types of thermal bridges and their impacts and a discussion of repetitive metal penetrations for cladding and component attachments.
This presentation to the ASHRAE 160 hygrothermal modeling committee explains why it is important to protect OSB and other moisture-sensitive sheathing materials from excessive seasonal moisture content cycling. Building codes and current hygrothermal modeling criteria do not completely address this problem. Appropriate use of exterior continuous insulation in coordination with interior vapor retarders offer the “driest” solutions.
How does foam sheathing on home foundations or above-grade walls perform with respect to termite protection? Concerns have been brought up based on a variety of anecdotal observations. However, good science can alleviate these concerns and lead to better termite protection practices in all construction. This Educational Program summarizes the available information on termite protection and suggest key general improvements to building code provisions, especially in the ‘very heavy’ termite risk zone.
This presentation, given by Jay Crandell (ARES Consulting) and Amy Schmidt (Dow Building and Construction) at the 2018 RESNET Building Performance Conference covers topics in energy code compliance, such as calculating the R-value of a hybrid wall and determining air space performance contributions.
Continuous insulation is used on foundations, exterior walls, and roofs. Continuous insulation provides maximum thermal performance by minimizing thermal bridging. It provides optimal assemblies that dry and also minimize seasonal moisture variations, creating a stable and durable environment for the building structure and interior.
This presentation, given by Jay Crandell, ABTG/ARES Consulting, and Amy Schmidt, DuPont, at the 2020 RESNET BUILDING Performance Conference, explores why walls should be a priority and the impact of ignoring energy efficiency, durability, comfort, and serviceability.
Applying Recent Building and Energy Code Advancements for Durable and Energy-Efficient Building Enclosures
This presentation provides guidance for and examples of the new building code advancements and their effective application for design and construction of code-compliant, durable, and energy-efficient building enclosures.
This presentation gives an in-depth background and guidance on the use of Frost-Protected Shallow Foundation (FPSF) technology and foam plastic insulating sheathing for reduced construction cost and energy savings.
The way we think about the health and safety of a building has changed. Building science leads the way in developing best practices and interventions that will result in the healthier buildings of tomorrow. This presentation provides a practical understanding of the topic and includes cost-effective, actionable guidance on how to design and construct healthy and resilient building envelopes in a post-COVID-19 pandemic world.
This presentation provides actionable guidelines to effectively consider, evaluate, and manage the balance of wetting and drying potential in common above-grade, light-frame wall assemblies in a broad range of climate conditions. This objective involves the appropriate use and integration of a wide variety of light-frame wall construction methods and materials including various cladding types, water-resistive barrier types, insulation types, and vapor retarder types or classes.

With the rise in importance of the energy code (IECC) continuous exterior insulation has become part of the solutions discussion.
This educational program and related modules are focused on the appropriate use of Polyiso sheathing and its application with respect to codes, standards, and other information useful for the proper installation by the construction industry.
