It has been suggested to me that I can extract illuminance data from TRNSYS using the weather data that is stored within the software but I'm not sure of the exact data I've now got. A calculation has been run for Helsisnki for example and the output was 168 hours worth of data which by the looks of things is in watts/m2 although it can't seem to find an explanation of what I'm looking at in the programme documentation. I am interested in data from across the year so I was also wondering how I might be able to get more data. Any support with this would be much appreciated.
Regards,
Caroline
