bs6399 wind code advice - global coefficients?

[steve101]

is there a global Cpe (exteral wind perssure) for roof loading?
i'm determining wind loads on a 15 x 30m x 8m high shed with a 12 degree pitched roof. I've just waded through all the local pressure co-eff checks, Fig 20 etc. is there a quicker way that i have missed to generate wind loads for concept design?
