I'm trying to model the energy savings due to improved glazing for an 
apartment building. The windows will be changed from single untinted, to 
triple pane low-e glass. In addition to better thermal charistics from 
improved U-value and SHGC, I am trying capture the savings due to the 
fact that the occupants will not have to crank up the thermostat to 
raise the air temperature to compensate for the radiant cooling due to 
single pane glass if you are standing near the floor to ceiling windows 
in winter.

I made a guess that the average occupant will put the heating set point 
at 68 instead of 70 since the improved glazing will block the radiant 
cooling effect. Is there a more elegant way to model this?
