Ecotect shows no significant analysis over options

[mikelwee]

Dear All,

whether any of you encountered the same problem as described below - and willing to share yoursolution in this forum

I am using 2012 revit version to produce options in bgXML files  for analysis in ecotect and green building studio

There are 5 options curtain wall panel configuration as described below, floor to floor height of typical storey is 4250mm

The analysis result did not give any clear direction. Ecotect produced exactly the same result accros the board, while Green Building Studio analysis showed confusing result

Option 1 with an additional row of fin actually INCREASE the energy use.
Option 3,4 and 5 shows no differences

the gbXML files is attached.

Are those BIM analysis tools really work for you?

Thanks in advance

Michael
