[Equest-users] double-skin curtain wall in equest

[Jackson, Alan]

We recently had to perform this analysis and worked with another consultant who developed a mathematical model to determine the DSF cavity temperatures throughout the year. Then we implemented the temperature schedule in a SUN SPACE in eQuest.

 

The downside to using the SUN SPACE is that daylighting calculation on the interior space does not work.

 

Not perfect, but in order to integrate into eQuest it seemed like a good solution. 

 

I am linking a BESTFACADE paper which had a chapter titled “Simplified approaches for the estimation of ventilation rates in double skin façade constructions”

This is not something that can be modeled reasonably in eQUEST alone.  One of the approaches that we’ve used was to couple a CONTAM + TRNSYS cavity model with an eQUEST model.  The eQUEST portion of this needs to be dealt with in the detailed mode.  If you don’t need to use eQUEST, there are various tools that can directly model DSF variants to one extent or another (i.e. TRNSYS, Energy Plus, IDA ICE, IES-VE, etc.).  These are fairly complex tools and can still be limited for some of the DSF configurations out there.  Perhaps clarifying your specifics would help to elicit more insightful responses.


Good luck, 

 

Paul

hillo: everybody

     who can tell me how to model double-skin curtain wall in equest, as far as i kown that there is no choose for this in SD or DD WIZARD.has anybody has experience for this,any words will be appreciated!

                                                                                                                                                           thanks!
