[TRNSYS-users] Advanced thermal insulation techniques

[Issmail OUHALLOU via TRNSYS-users]

David,

It's clear now, thanks. I need to insulate the external wall, and for that
I have to compare the impact of insulation on thermal comfort, for two
cases: *1.* if the insulation (rock wool for instance) is placed inside the
wall, *2.* if the insulation is placed back of the wall (external side). Is
it possible? How to do so? The problem caused by the difference between the
thermal insulation from the outside and the thermal insulation from the
inside is the effect of the thermal bridges ...

*Note:* I only use Trnsys3d for modeling my building.
I appologize for my english if it's not clear enough cause I only practice
this in french. Thanks.


Best,
Ismail
