Keeping HB Glass Modifier consistent with HB Window Construction

[LiLi1010]

Hi,

I run an energy simulation, and now I want to perform daylight simulations (daylight factor, point-in-time illuminance, sDA, and UDI). I want to ensure that the input of the HB Glass Modifier is consistent with my HB Window Construction.

For the HB Glass Modifier, what should I use as the input for the transmittance so that it matches my previously defined HB Window Construction? Should I deconstruct the window construction and use the visible transmittance (t_vis) as the input for the HB Glass Modifier, or is there a recommended way to keep the Radiance modifier consistent with the EnergyPlus construction?

Thank you in advance!

Yes, this will definitely work to keep things consistent and it’s the recommended way to do this with the officially release LBT components.

Thanks a lot for confirming.
