Some points without any warranty ;-)

- It is an open system, you cannot evacuate it or fill it with any 
special gases

- There are several options to improve perfomance like reducing solar 
transmission or adding e.g. translucent insulation, coating inside 
surfaces,...

- For double-glazing, the heat transfer should be about 2.8 W/m2K in a 
simplified model. However, it may be interesting to have a closer look 
at the non-homogenous facade structure.

- Visible light transmission in the double-glazing setup could be 
assumed to be about 75% - however be aware of scattering, this is not 
clear glass and thus cannot be treated as such when you look into 
daylighting.

Cheers, Lars.
