[TRNSYS-users] Long wave emissivity of walls

[Christophe PLANTIER]

Dear Trnsys-users,
 
I'm trying to modelize a low emissivity material to evaluate its impact on summer confort of buildings. Can I change the long wave emissivity of the outside surfaces of walls? I read in the User Guide the default value of emissivity is 0.9 for any walls.
Has anyone ever tried to modelize this kind of "reflecting" material?
Thanks a lot for your help,
Best regards,
