I used DIVA for simulating the annual DGP for 1 model but with 2 cases. In case 2, i tried to reduced the area of the column on the window facade in order to have more daylight get in on window.
However the results showed that in case 2 (with larger window opening) has less DGP than case 1. I also tried the point-in-time simulation for the 2 cases but case 2 always has less DGP than case 1 at the same simulated time.
I upload some photos here for reference.
Thanks alot for your help.
