wind load NBCC 2005

I'm working to design a steel building using NBCC 2005 ( National Building Code of Canada 2005 ). I would like to know how can i evaluate the internal pressure coefficient CPin ( for WIND LOADS) , since the code gives only ranges of this coefficient, an my building is on category 1.

You would need to account for pressure and suction both internally and externally, so technically you would have 4 different combinations to determine the worst case. However category 1 there is only one coefficient as the other is zero, therefore you've got to combine the interior value with both the pressure and suction from the exterior to determine the worst case.

Thank you so much, that was helpful
