Using Honeybee Window Material and HB Window Construction tools to assign glass material for apertures in a HB model used for the HB Annual Daylight

Hello all,

I am new to using Annual Daylight analysis in Grasshopper. I am using 1.6 Ladybug/Honeybee version. I need to use the Honeybee Window Material instead of the HB Glass Modifier because my variables are u-value, g-value and Visible light transmittance of glazing. However, when I assign this material as apertures on my HB model and plug in to the Annual Daylight, the heatmap does not affect by changing my variables (u-value, g-value and Visible light transmittance) (I mean the DA output is the same even though I change g-value which should effects the daylight transmittance). On the other hand, when I use the HB Glass Modifier and use different values for Transmittance, the heatmap by daylight analysis changes. I need your assistance to use the Window Material effectively in the annual daylight analysis. I attached the GH file and images.


This is the image from the Annual Daylight simulation. The panel linked to the output DA shows the percentage of illuminance. The numbers do not change when I change the window material inputs.

Hi.

Is your model in meters?

This is a requirement for most of LBT.

If it is, then your grid and offsets look weird. If it is, change and try again.

If you have problems after this, try posting again and including the file.

Hello, my model is drawn in millimeter. If I convert it to meters, does it resolve my issue?

I would expect so, yes.

Hello,
my model is in meters, yet I keep getting the same results no matter the window construction I chose.
Do you have other suggestions ?
