Convert 4A constructure

i want to convert 2a,2b constructure from ashrae .
but not ability to choose a or b .

Does anyone know how I should select constructure 2a or 2b in the hb library

Just select “2 - Hot” from the drop-down. The ConstructionSets for climate zones 2A and 2B are the same. The distinction between A and B really only becomes relevant in the design of HVAC systems. The wetness/dryness of the climate really doesn’t affect what level of insulation and SHGC you should use.
