[Equest-users] Translucent Glazing in equest

[Sami, Vikram]

I would suggest reading up on the split flux method used in eQUEST for the indirect component of daylighting. If you are looking to model daylight dispersion from this, I would suggest that eQUEST is not ideally suited for this. Radiance might be a better bet for your daylight performance. Thermally – eQUEST should be able to handle this.

To clarify, do you mean “from clear to diffuse?”

Whether eQuest can explicitly simulate or sufficiently approximate light-scattering fenestration systems may depend on your ultimate purpose.  Are you asking specifically to capture a difference in daylighting control behavior, in distinction from a clear glass system?

If not, capturing the thermal behavior should be do-able.

I can match the three value, but I can not find the way to change the glass from clear to translucent .

Farid:

'What are the properties of Kalwall? If you can match U-value, shading coefficient, and visible transmittance, should be no reason you can't simulate it.

Hi,
Does anybody knows, how I can model a kalwall (translucent material) in equest? In the glazing wizard, I have no choice of translucent material. All I have is clear or tinted.

Thanks,
Farid
