ETFE simulation_ EP and Radiance

[NobleSix110]

Hi. I think this chat is kinda unnactive nowadays, but it has cool information on it.
Thees days I’ve been working on a energy simulation of a project that also uses ETFE cushions.
I also tried to apply aproximate transmittance values to a surface to “emulate” the sistem, but i have no clue if i’m doing it correctly or not.
What values did you use?

Thank you very much

Hi Everyone,

I wonder if someone has further investigated the simulation of ETFE materials.
I shared my study in this topic:

ETFE modelling for daylight analysis

Hello everyone, I write to ask for some technical advices for a project where I would like to model the ETFE material of the skylight of an atrium in order to estimate the effects and possible problems of glare inside the space with different types of fritting. I read the article “A New Approach to Modeling Frit Patterns for Daylight Simulation” and different posts. I tried to model the ETFE material by using the Radiance function “Perforate.cal” but I would like to understand if the results …

It would be really helpful to have some advices or inputs

thank you
