NAIMA has developed a map showing thermal recommended levels of insulation for various climate zones. The commercial IECC and ASHRAE 90.1 introduced the R-12 code change in an effort to address the inefficiencies of these types of duct systems. ; R-5.7ci is allowed to be substituted with concrete block walls complying with ASTM C90, ungrouted or partially grouted at 32 inches or less on center The calculation for percentage of glazing in ASHRAE Standard 90.1 and the IECC are different as the IECC only looks at above grade walls and 90.1 includes both above and below grade walls. Make sure the installers get the attic sealed airtight. International Energy Conservation Code: most states that have adopted the 2009 version or a more current version. 3.
