Building an EPW: Creating Normal Solar Radiation from a ASHRAE Revised Clear Sky Model (“Tau Model”)

Thanks. So there will be no update to the UpdateGHfile, its no longer necessary as all components in script now updates with the updater.

I also have a question regarding the standard Ashrae clear sky. It seems the clearness number does nothing to the irradiation in the WEA.

This must be a bug right? or am I getting something very wrong?
