IES-VE User Forum

Are there any known workarounds to model transparent insulation materials (attached to thermal mass layers) in IESVE?
Hope that you can help!

Thanks,

Hi,

I think you best option if you want to consider the solar gain is just to use a double glazed unit or Translucent shade object in VE 2019 and modify the properties according. You will find some details on matching manufacturers data in the back of the Apache constructions database user guide.

Thank you for the reply, but that is not what I am looking for.
A Transparent Insulation Matierial works similar to a Trombe Wall, with the main difference, that there is no air gap between the thermal mass and the insulation layer. The main feature of it is the thermal mass, which makes it perform much better than a double-facade with the same U- and g-values.

I have now modelled it as a Trombe wall with a small air gap: a glazed, unconditioned zone with a depth of 5cm representing the outer side of the trombe wall and a single layer interior wall representing the thermal mass behind it.

Do you think that this approach could work?
