I have been trying to model ETFE cushions for EP and Radiance. For Radiance I am introducing manually results as produced by LBNL but for EP I have my doubts if a representation of a single layer using “windowMaterial” component is enough as ETFE cushions have a different behavior than that of a glass window. Especially when it comes to model more complex ETFEs with extra (shading/printed) layers and varying behavior during time I think that any simulation that is currently available is not representative enough. Any ideas/thoughts?
I am attaching a paper “ENERGY MODELLING OF ETFE MEMBRANES IN BUILDING APPLICATIONS” from H. Poirazis et al explaining the behavior of ETFEs (p. 701) with with a frit intermediate layer as a reference.
Thank you in advance
