Decarbonization of Buildings: A Review of Climate Science, Policies, Practices, Data, and Recommended Actions for Buildings and Building Materials

This “open file” research report was written to provide a comprehensive review of climate science, climate policy, the status of US energy use and greenhouse gas (GHG) emissions, and the decarbonization of US buildings. The report discusses the importance of a “total carbon” approach when setting policy or making decisions related to insulation materials, which deliver substantial benefits for energy efficiency and the avoidance of building operational GHG emissions.

2021 IECC Commercial Envelope

Presented as a live, full-day course at the 2024 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.

Water, Wind, Windows & Walls with Continuous Insulation

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.

Moisture Control for Durable & Energy Efficient Cold-formed Steel Walls

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.
