Re: (no subject)

You should use wind tunnel testing.

(Just kidding.)

I presume you're concerned with C&C, since there are MWFRS Cp numbers for slopes greater than 45 deg in method 2. I'm not sure, but the last time I ran into a simple case of <45 on a residence, I think just took the flat wall value. In that case it wasn't going to make a large difference in the answer so the extra effort was not justified.

Hello All

 

A wind question.....if my Gable roof slope exceeds 45 degrees or my Hip roof slope exceeds 27 degrees do I have to use the Method 2 ?   Why...since none of the variables used in method 2 ask or care about roof slope.
