Hello all,

EnergyPlus Transparent Insulation Material (TIM) module is described here

I was wondering if there is anyone who used the TIM module with MaterialProperty:SpectralScheduleData module to include a spectral schedule? I have observed these two modules might not have a connection at all.

I would appreciate any pointers on this matter. Thank you and kind regards,

@sajithwjay I would recommend referencing EnergyPlus documentation managed by Big Ladder Software, since they release free web docs for each version of EnergyPlus. The docs you linked to appear to be for EnergyPlus v8.3, which is from 2015. Here is the latest Engineering Reference section for the TIM module.

Hi Aaron, thanks for getting back. I was referring to the documentation from Big Ladder as well. I was using the radiation coefficients defined through WindowsMaterial:Glazing at first to use for the movable insulation layer as pointed out by the Big Ladder article. However, I wanted to extend it to use a Spectral Schedule instead of averaged values.

This is done through MaterialProperty:SpectralScheduleData and is being used in Wndows. I was wondering if it was ever implemented for TIM as well?

Kind regards,

I haven't tried to do that myself, hopefully other users with experience in this can respond.

Have you already tried testing with example IDFs or other simple models to see if this combination works?

Thank you Aaron, I am looking into it further. I will mention if I find further useful information on the matter.
