Earthships have large indoor planters inside the south wall (which is
mostly glass). You need about 1 sf of planter space for each gallon of
water used per day. You do need some way to handle overflow - usually a
leech field, but in an urban setting I suppose you could just use the
sewers. Most people grow food in these.
Toliets should be composting so that balckwater never enters the waste
stream. No reason why they couldn't work great in apartment buildings.
Power generation would work even better for apartments than homes. Solar
panels on the roof.
No reason you couldn't get all the water you need via rainwater catchment
systems and filters.
So you see you could have an apartment building that does not use sewers,
water lines, or power, and which grows a lot of it's own food.

What's wrong with the sun during the day and compact floresents at night?
