Energy Evaluation (Infiltration, CAV-settings, Glazing ratio and Building system settings)

I have a few questions about different smaller things in the Energy Evaluation tool:

 

1) Infiltration

When changing the infiltration in the structures as well as the windows to e.g. 0,9 the fully calculated infiltration is much higher. Why is that?

2) Ventilation settings

Is the Air Flow value per squaremetre or in total?

3) Glazing Ratio 

What is the glazing ratio in relation to? It seems to be way too low if it's related to the outer wall area.

4) Building systems settings (example: District heating)

I am really confused as to what these settings represent. How do I fill these out properly?
