Dear Trnsys-users,

For an analysis of Belgium weather data, I constructed weather files 
using the Trnsys type 109 and 15 and the meteonorm file for Uccle, 
Belgium.  Making a summation of the resulting radiation on vertical 
planes facing N, E, S and W, I notices big differences.  The table below 
indicates this :


	T-drybulb                 	I_tot_hor-1             
	I_tot_hor-2             
	I_tot_N        
	I_tot_E               
	I_tot_S       
	I_tot_W
Datareader 15-6 	9,73 	3416548 	3416548 	2302065 	3075940 	3625084 	3081463
Datareader 109 	9,73 	3416548 	3416296 	1192961 	2087489 	2720244 	2076203
Datareader 15-2 	9,73 	3416548 	3416548 	2302065 	3075940 	3625084 	3081463

	
	
	
	
	
	
	
Difference 15vs109 	-5,91E-05 	0,088266 	251,4136 	1109105 	988451 
904839,9 	1005260

	0,00% 	0,00% 	0,01% 	48,18% 	32,13% 	24,96% 	32,62%


The two horizontal radiation values are : 1)directly provided by the 
weather file and 2)processed using a plane with slope 0°
Am I doing something obvious wrong?  Because the results are cearly too 
different to be acceptable.
The dck files is included.

Many thanks,

Maarten Sourbron
