How to change heat trasfer coeficient for windows

[Anonymous]

Hi.

I have problems with my revit 2019. My issue is that I want to change window heat transfer coeficient for windows manualy. Because I need A+ class window, which heat transfer coeficient is much better. Revit best heat trasfer coeficient is 1,5330 (W/(m2K) for windows, but I need 0,9 (W/(m2K) for A+ class buuilding

the Heat Transfer Coefficient is just a parameter.  You should be able to edit the family and change it in the Type Properties of the family. then reload it into the project.

. 

it is a Type Parameter, so if you have multipal types in the family it will need to be edited for each Type.
