Re: [TRNSYS-users] Long wave emissivity of walls

[David Bradley <bradley@tess-inc.com>]

Cristophe and Bastien,
 I believe that the emissivity of walls in Type56 is assumed to always be 0.9 and that there is not a convenient way to model low emissivity materials in TRNSYS 16.
Kind regards,
 David

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,
