Weather File of QATAR

[junaidbinnaseer]

Dear All

The design weather file used by IES Ve (ASHRAE) is for peak DB and coincident WB. How can you size your FAHU when they experience high latent load at highest WB?

Can you change a variable(i.e. WB and DB) in the design weather table for instance the peak WB will be highest in the month of January for Qatar?

Thank You
