Probably passive (taking advantage of energy and natural laws already present in the environment, like wind and convection) vs. active (making use of secondary forms of power like electricity, burning fuels, etc.) is a better distinction. If all you gotta do is e.g. at most open some vents at one time of day and close them at another, and not rely on the delivery of external power sources from human industry, calling it “passive” is pretty fair.
I like this passive vs. active distinction. A sailboat vs. a motor ship. And a hybrid approach that uses naturally occuring energy flows when feasible; artificial energy sources when not.
