I have been performing a solar insolation study on a building. And I have found two components: LB epw Import and LB STAT import. When I used radiance outputs from STAT into sky matrix, the annual results are almost double than the results produced from LB epw Import outputs for certain positions. What do you think is the issue? What is the difference between direct clear radiance and direct radiance? And which one should be used?
Thank you so much!
