[Bldg-sim] Is there a quick model for double skins facades?

[Nick Caton]

Hi Vik,

 

I hate to trample over anyone's little flower patch, but I've read some scathing assessments of double-facades as an energy-saving strategy.  You might want to check this and the associated references out: http://www.buildingscience.com/documents/insights/bsi-007-prioritizing-green-it-s-the-energy-stupid.

 

That said you might not be satisfied until you develop your own conclusions.  Proponents of this approach repeatedly cite benefits of CFD, so to give a "fair/proper" assessment any tool you work with would probably need to be modeling convective airflows between floors.

Subject: [Bldg-sim] Is there a quick model for double skins facades?

 

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