[TRNSYS-users] airchange between zones

[Alex moreno]

Hi

I have a doubt when i modeling a single family building with two floors, 
how i can connect the airchange between of  two zones (first floor and 
second floor)

another doubt is:

Firstly i simulated the two floors us one zones, but now i simulate the 
buildign us two zones, the results of heating differ 2% respec of  one 
zone building and differ cooling 10%, it is normally?

regards


Alex
