[EnergyPlus_Support] RE: windows certified with European technical standards



Thank you, Jean and Rahul. 

I see that as "environmental conditions" in the software Window 6 there are "NFRC 100-2010", "NFRC 100-2010 winter", and ""NFRC 100-2010 summer". Does EnergyPlus evaluate the properties in the "NFRC 100-2010" conditions?

I see that between the European standard and the American standard the differences can be particularly high for low U-values and large air gaps:

Yes. I propose using Window 6 or higher to model the glazing system and adjusting the values until they corrispond with yours using the EN 673 settings. Once you have a match, simply change the settings to the American settings to get the equivalent U-values and SHGC at these test conditions.

I'm modeling a building according to ASHRAE 90.1-2007. It is a design building. 

I got U-values according to European technical standards 
ISO 12567-2:2005
and 
EN 673:2011
I'm modeling the glazing surfaces with the object WindowMaterial:SimpleGlazingSystem
Do you know if I have to change the values before writing them in EnergyPlus, in order to consider different test conditions between European technical standards  and EnergyPlus?
With Regards
