Hi, I have some questions about the modeling system on CI.
1.If I have a curtain wall window on the exterior of my building, I still need to use U-value of the faming system?
2.My project tenant scope is only the half of the 4th floor, can I model only the complete 4th floor or I have to model all the building?
3.If I have system 6 for the building of 155164sq ft total area (118,849sq ft conditioned area) with 4 floor, and my tenant scope is the half of the 4th floor, so my proposed case have to be model with the design documents, but in the other half that I don't have the information I have to use system 6 to be neutral with the baseline?

Thank you.

Best Regards,
Juan Carlos
