Kiran,
I would say that you can select the best tool depending on your needs and the required output.
The mode of the DSF (natural/mechanical ventilation), the control systems, the position of shading within the ventilated cavity, the type of DSF (multi-story, box window, etc), the origin and destination of the air (DSF, airflow window), etc are some of the parameters that will define that.
In terms of tool validation of DSF there was an IEA validation task (34) (http://www.iea-shc.org/task34/subtask/index.html) that you can look into and see the comparative and empirical output.
I am using IDA ICE 4.0 (incorporates the ISO 15099) and E+ depending on my needs. I believe that in DSFs it is essential to have an insight on the tools physics and these 2 tools allow you that.
There are simpler tools depending on your needs such as Parasol (also using the ISO 15099) and WIS for steady state boundary conditions.
As to calculation methods you can download the literature review report from the IEA website: http://www.iea-shc.org/publications/downloads/Task34-Double_Skin_Facades_A_Literature_Review1.pdf
I hope this is of some use.
Best regards,
Harris Poirazis

Hi all,

Can anyone suggest the best tool to model double skin facades with glazing?
