=IF(AND(h/d>=1, h/d<=5), 1.3 - 0.3*(h/d -1)/4, IF(h/d<1, 1.3, IF(h/d>5, 0.8, "error"))) Better: Use a linear interpolation table for ( c_f ) based on ( h/d ) ratio and wind incidence angle. For buildings with height < 15 m and non-slender, ( c_s c_d ) can be taken as 1.0. For dynamic sensitive structures:

Then, use =VLOOKUP(z, TerrainTable, column_index, TRUE) to get ( c_e(z) ). In the "Peak Pressure" tab: wind load calculation excel sheet eurocode
