[Bldg-sim] LEED: modelling a double façade

[Gal, Amandine]

Sorry I haven't any data with EnergyPlus. The only thing I know is that EnergyPlus is able to understand that the radiation is passing through both glass layers of the DSF and that now you have the "small" CFD which you can couple to the usual thermal simulation in E+ but I haven't try it. 
 
I think I will follow my idea to create a model in Equest and model the DSF in E+. 
Do you think it is a good idea for LEED documentation to make a simulation with Fluent? Because I don't think we will be able to make a wind tunnel test (too expensive).
 
Regards

Hi Paul and Amandine

I am working for some time on DSF and I had data both from buildigs and test cells. Now I have a student using En+ trying to match the collected data (test cell) and there are some problems. If you have some published or useable results I would appreciate. 

Regards

Fernando


	Amandine,
	 
	We have had success (with a ventilated facade DSF configuration) using an approach similar to what you're proposing.  The challenge with it and other configurations depends on the interaction of the DSF and the building spaces.  We coupled eQUEST, TRNSYS, COMIS, and wind tunnel test data to achieve what seems to be a reasonable solution, especially for the purposes of a cost analysis and LEED documentation.
	 
	Regards,

	Paul

	Dear all, 
	 
	I am modelling a building with Equest and I would like to know as Equest is not so efficient modelling passive system if I can use EnergyPlus for the double-façade only and after add the results of E+ to the one of Equest.
	 
	Thanks 
	 
	Regards
