[TRNSYS-users] Radiant barrier

[Ilyas Ismaili <karaktus@gmail.com>]

Dear TRNSYS users,

I'm trying to model a radiant barrier in the roof of a building, so I put a 10cm airgap into the external roof layers, and I set the back absorptance of the roof to 0.05 (since radiant barrier can achieve up to 95% heat reduction, correct me if this value is wrong).

Is this modelling correct, or there is another way to do it?

Regards,
