Following is the wall insulation in IDF file:
!- wall insulation and framing material: R21
Material, wall_consol_layer, !- Name Rough, !- Roughness 0.1397, !- Thickness {m} 0.05966275, !- Conductivity {W/m-K} 120.801, !- Density {kg/m3} 1036.25775; !- Specific Heat {J/kg-K}
But the calculation result is not equal to R21. (0.1397m)/(0.05966275W/m-K)=2.341494484m2-K/w = R13 Why?
