Zone Window Heat gain is higher after shading

Hi,

I have modeled two identical buildings, one with shading and other without shading. The screenshots of the same are attached for your reference. I am getting lower zone window heat gain peak load in building without shading. The time of peak is on 21st may at 15:00 hours. 1)Max Zone window heat gain without shading: 4497 W 2)Max Zone window heat gain without shading: 4963 W

The shading has been designed to block the sun for maximum time of the year and I hoping to see a considerable reduction in window heat gain due to extensive shading. However, the heat gain has increased after shading. I would appreciate if someone can explain this behaviour.
