It should be possible to have a system that generates automatic airflow should power fail.
Best ones I've found are solar panels, or geothermal power generator (geothermal is generally really amazing for everything), but that still leaves mechanical failure.
That said, it takes quite a bit of time before ventilation failure leads to a dangerous CO2 buildup. And the addition of having a single entry point for air means that it's easy to filter my air through a HEPA filter, ensuring top quality air all year round.
A proper passive house generally only has one maintenance point, which is the ventilation / air filtration system, and temperature control is easy. You don't have to worry much about the insides being too hot or too cold, as it should keep whatever temperature you set regardless of the weather outside.
With all that said, you should generally take everything I said with a grain of doubt, as I'm not an expert, and someone could well shoot down all my points in the comments. ;-)
My prime goal with any house I buy is to make sure that I have to do as little as possible; never worry about water being in the wrong place, and never worry about the power bill, or temperature in general.
My personal interest in passive buildings generally revolve around maintenance. Passive houses seem to require far less maintenance.
...I'll see myself out.
But then again, I don't have flagging rights yet, so who am I to judge?
My gripe isn't as much what the minimum requirement is, and more the incentive to never go above it, because property prices are generally only going up with little regard to building standards.
