How to Design and Construct Concrete and Masonry to Comply with New Energy Codes-Introduction to ACI 122R-14- Guide to Thermal Properties of Concrete and Masonry Systems (Recorded presentation)

Introduction to ACI 122R-14- Guide to Thermal Properties of Concrete and Masonry Systems (Recorded presentation)

Video Transcription

Video Summary

The presentation provides an overview of the updated ACI 122 document, which covers the advancements and changes made in concrete and masonry standards focused on optimizing thermal performance. Key updates include the addition of a chapter for notations and definitions at the beginning for clarity and to eliminate inconsistencies. The former chapter on Thermal Mass is now titled Thermal Inertia to distinguish between the concepts clearly. The document now features separate tables for inch-pound and SI units to avoid confusion, with extensive data moved to an appendix. The series parallel method is recommended for calculating thermal resistance in concrete masonry, and considerations for thermal inertia are included to ensure energy-efficient building design. The committee is seeking expertise to further develop code language to ensure concrete and masonry materials remain competitive, especially against prescriptive energy code provisions favoring higher R-value materials.
