We are doing a project in a pretty cold climate. The project design has a really big glass fa?ade facing south. One of the ideas to reduce conductive heat loss is to create a double skin fa?ade on the south side.

Now I realize that this is going to take a fair amount of analysis work to design it properly. What I was wondering is if there is a quick analysis tool/methodology to tell if this is even feasible to go into more detailed analysis.

Any help would be much appreciated
