Hello All,

When setting transmission factors at 15deg increments of external shading device, how does VE evaluate its transmittances of intermediate incident angles (say, 20deg or so) ?
I wonder if VE uses linear interporation or any other method.

Thank you in advance!

Hi,

Linear interpolation is applied between the values entered at the specified points.

You could test this yourself quite easily as well

I'll try it.
