Re: [TRNSYS-users] diffuse radiation from Type 16 to Type 34??



David,

thank you for your answer.
Finally there are 2 questions: 
1) Is it right, that the output from Type 16 is horizontal diffuse radiation
without a ground reflected component but the input to Type 34 should be
horizontal diffuse radiation with ground reflection?

2) Is this the reason why the incident diffuse radiation on a vertical wall
coming from Type 16 is different to that one from Type 34 (If I set
wingwall/overhang projection to zero)? During a day sometimes is Type 34
bigger, sometimes Type 16 ...

Kind regards,
Stefan
