2 www.InsulationOutlook.com Understanding and complying with todays evolving energy codes and standards presents unique chal- lenges for architects designers and builders of pre- engineered metal buildings. As the new energy codes and standards the Inter- national Energy Conservation Code IECC 2012 and 2015 and ASHRAE 90.1-2010 and 2013 are being adopted across the country specifiers are find- ing that conventional single and double layer fiber glass insulation systems may no longer be able to meet the thermal performance requirements specified for metal building roofs and walls. In an effort to navigate and hopefully simplify energy code compliance the intent of this article is to help specifiers determine code adoption status using web-based tools and to review various high R-Value Low U-Factor insulation systems currently available for metal building roofs and walls that provide code compliant options. Code Adoption Status Many states and municipalities have adopted recent versions of either the IECC or ASHRAE 90.1 stan- dard or drafted their own energy codes.The Depart- ment of Energy DOE has summarized the current status of energy codes and standards adoption across the United States in the map below. This map is available at www.energycodes.gov. Additional information relating to code adoptions can be found using the Energy Code Navigator at By Hal Robbins Navigating
