[EnergyPlus_Support] ASHRAE 90.1 compliance for building fabric

["mtdagustin" <mtdagustin@xxxxxxxxxxxx>]

Dear E+ Users,

I am trying to model a non-residential building located at Zone 1 as 
defined by ASHRAE 90.1. However, I am not sure if I have interpreted it 
correctly. Table 5.5.1 , "Walls above grade" calls for Assembly maximum 
(Mass) = U-3.292 and insulation R-value is not required. Comparing this 
value with other wall systems i.e. metal building 0.642, steel frame 
0.705 and 0.504 is not comparable.

Could someone enlighten me on this issue.


regards
F
