ENCalculator Program
ENCalculator is a free site exposure factors calculator for EN1991-1-4, Eurocode 1 - Wind loads.
This version of the EN1991-1-4 site exposure calculator implements the rules in the Draft for Public Comment of the UK National Annex. It is expected that there will be some changes to these rules in the final published version of the UK National Annex that will make this version obsolete. A new version of the application will be posted here when these final changes are known.

Instructions
Download the zip file and then uncompress or extract the ENCalculator.zip file and place in an appropriate location on your computer. Create a shortcut on your desktop for easy access (right click on the ENC.exe file, select "Send to" and then "Desktop as shortcut").
Use the text boxes or sliders to set the correct values for effective height, distance to sea and distance in town. The program will not allow invalid combinations - for example, being one kilometre for the sea but 2km inside town. Also, note that the sliders for distance have a lower limit of 0.1km because of the logarithmic scale). If you want to set 0km, just use the minimum 0.1km setting.
