Dear eQuester:
I want to run a simulation by EEM wizard. I want to replace exiting single pane, 
clear windows with double pane clear windows for a school building. 


I changed the class type form single pane clear to double pane clear windows. 
 The energy saving doesn’t look good.  I have two following questions need 
someone's guidance. 

Question 1:
My question is that this EEM will reduce perimeter infiltration rate of the 
building. I am not quit sure if I need to reduce the perimeter infiltration rate 
in the simulation. If, it does, how many percentage of infiltration rate do I 
need to reduce? 

Question 2:
Does eQuest programmer has already considered this issue and changed the 
perimeter infiltration rate automatically with changing window glass type and 
insulation of the windows?
