I was doing a simple radiation result using Ladybug radiation component and real time radiation analysis. I compared the result from the radiation analysis (I looked at radiation result not total radiation) for one day (151 w/m2 when i converted it from kWh/m2), and then ran a full year result and checked the results on the same day using the real time radiation analysis and got a bot higher results (155 w/m2). Is there an explanation for that?
I also noticed that I was receiving a direct component in the radiation result at one hour, however when looking at a simple shadow analysis in Rhino the neighboring building was shading this window at this hour. My assumption is that this is because of the sky division and accuracy, that the sun patch might be big in the sky division and therefore the window is receiving some direct sunlight even though it should not at all. is there another explanation for that?
Thanks in advance,
