This proposed addition will change how almost every building will be built, impacting all U.S. states except seven (AL, FL, GA, HI, LA, MS, SC). Addendum av restricts how concrete, steel, and wood components - such as floor slabs, shelf angles, balconies, overhangs, fins, parapets, exposed columns, projections, and penetrations - can be detailed and built. View Addendum av at http://bit.ly/2OVpTic.Mitigating thermal bridges is a known methodology of saving energy. There is concern with this specific addendum, however, because this 26-page public review draft is complicated and these provisions have not been tried on any real projects in any U.S. jurisdiction. Because Standard 90.1 serves as the basis for minimum energy savings required by federal law for all states, and a compliance path for the IECC, input is needed from engineers, architects, and contractors during the public review to ensure that these requirements are technically sound, practical, and cost-effective.The public review period on addendum av ends on Sept. 17, 2018. Instructions for submitting comments are available at https://www.ashrae.org/PCToolkit/OCD (membership in ASHRAE is not required).Learning Objectives:1) Identify the climate zones or areas of the U.S. and Canada where the criteria would apply2) Identify ways that balconies and shelf angles would comply3) Identify main construction element at the roof/wall intersection that is a thermal bridge of concern and how it would comply4) Identify the ways that intermediate floor
