I am writing reporting measure on openstudio. For Simple glazing there is a option to set u-value directly in openstudio and in coding I can directly access u-value of Simpleglazing using 'uFactor' function but in case of Standard glazing this function is not working. How to write code to access uFactor of Standard glazing?

uValue = sub_surface.uFactor.to_f
