ETFE thermal modelling

Hi,

I am trying to find a proper way to model an ETFE cushion in a dynamic
thermal modelling software. The main problem is that ETFE is not opaque
to longwave, so modelling it as glazing is not acceptable. The radiant
temperature is the main output of these calculations. Sizing the effect
of longwave for different conditions would be also interesting as an
output. I was wondering if there is a software that could handle this
kind of materials or if there is a way in existing software to go around
this problem and get reliable results.

Thanks a lot,

Harris, 

It's been years since your post and you've since written papers on this. Is there a validated approach for modeling ETFE cushions? Do we know which simulation engines are best suited for this task?

Cheers,

Jamy
