Re: [EnergyPlus_Support] Re: Help : Simulation of External Zone

[rachit kumar <archi_rachit@xxxxxxxxxxx>]

Hi

Thanks for the reply.

 

I tried Holes in Design Builder. Holes are modeled using clear glass and work as an air flow path. In case of large holes (e.g. 500 square meters courtyard in my case), due to glass the incident solar gain is high which would lead to high operational temperatures. And in my case I am going for naturally ventilated open courtyard.  

I also tried Holes through calculated natural ventilation with 100% glazing opening. The calculated natural ventilation does affect much in reducing high operative temperatures. 

 

I know, there are certain limitations with the approach because I am attempting to model an external space using an enclosed zone. Kindly help me with more solutions.

 

Thanks

 

Rachit

Hey

I would probably model two zones for this courtyard, one till 10 feet high and the other from this height on, with both connected by a hole. I think you can put a hole on the "roof surface" of the upmost zone too and thus simulating a open space.

Well if you use DB as your modeller things are gonna be easier, but you can do it with OpenStudio as well.

Hope it helps
