[Bldg-sim] Design Builder : Low E coated surface

[Chris Yates]

Hi Deepa
I think flip means swap the place of inside and outside pane - not  
flipping the individual panes so that the coating moves to the  
opposite surface.
DB uses the International Glazing Database which you can download from  
lbnl. It's easy to use so worth downloading a copy. Unforunately you  
can't transfer the results to DB at present.
