Hi,
I'm working on a pre-assessment for a project in Morocco and would like to see the minimum wall insulation.
I checked in ASHRAE 90.1-2010 but Morocco is not listed in Table B3 International Climate Zones.
Does anyone already had this issue and now what climate zone is appropriate for Morocco ?
Thank you for your help.

Look for the .stat file in the EnergyPlus weather database. The .epw files can be used also in other software (e.g. in IES-VE).

Thank you for your answer. The datas will be useful to make the calculation in the future.
But for the moment I'm looking for the climate zone of Morocco (1B, 2A, 3A, 3B ?). I need it to check the insulation thickness needed on the project.

A word of warning. The climate zones generated in the .stat files are based on the statistical yearly weather file AND DO NOT always correspond to those listed in Standard 90.1. THEY MAY NOT ALWAYS BE THE SAME and you have to use those in Standard 90.1, if listed.

Thank you for your answer.
If it is not listed do you know where I could find it ?

Well then you need to calculate it. HOF lists the Heat./Cool. Degree-Days (HDD / CDD 18.3) for Morroco for 11 different locations. Google CZTables.pdf to see the calculation proceedure at the end.

I received an answer from ASHRAE :
Table B-4 includes a chart to let you determine the climate zone based on HDD and CDD of the location. The degree day information can be found in ASHRAE Standard 169 or the ASHRAE Handbook. From the ASHRAE Standard 169-2013, most Moroccan cities appear to be climate zone 3 or 2:
