LB Cumulative Sky Matrix

Hey everyone,

I’m trying to calculate different shading factors using different types of geometry and the components “LB Sky Matrix” and “LB Incident Radiation”. I wanna make it so the user can choose to get monthly values (A list of 12 shading factors) and hourly values (a list of 8760). Maybe daily as well. My problem is that when I input a list of hoys, for 0…8759 (So every hour of a year), into the sky matrix and the into incident radiation the results are cumulative. So I get one total value for the whole year and not one value for every single hour. I can fix this by grafting my list and creating the skymatrix for every single hour 8760 times, but it takes too much time. I’m really hoping there is an easy fix since I need the hourly values for precise analysis further on. I hope I made myself clear (552.2 KB)

Thank you in advance!
