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.
This guide from the Steel Framing Alliance, updated in 2015, addresses thermal design analysis and code-compliance best practices for cold-formed steel (CFS) framed walls.
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.
The focus of this report is on uniformly distributed point thermal bridges. The main goal is to provide data to help better understand the implications and support an equitable, performance-based treatment of such thermal bridges for common building assembly conditions and variations.
