Design Database - Average elevation angle for surrounding buildings, terrain and cityscape

Hi there,

I have a room where there is surrounding infrastructure/trees etc. I have played around with the "Average elevation angle for surrounding buildings, terrain and cityscape" function and found that increasing the angle will reduce the amount of time there is a solar load on the building, but the peak temp inside the building increases in comparison to an angle of 0. This has been in the Summer function.

Looking to understand why this is?

Thanks,

Tim
