the amount of concrete in a tower is incredible. then there is all the hallways, pools, work out rooms, and common areas need to be heated, lighted and maintained. as well as the large windows, elevators, storage areas, underground parking.....

With a tower your insulation is more efficient (sharing 2 or 3 walls with other residents will do that) and heating/cooling is obviously more efficient due to that and economies of scale. The insulation argument may not apply to towers vs lowrises, but the economies of scale one does.
There's also other things to consider like the amount of density in a tower creating large positive externalities for transportation. If I open a store (or community centre, or whatever) next to a tower complex with 1000 people, none of them have to travel far. If I open a store in the middle of single-family houses containing 1000 people, you can bet a bunch of those people will have to drive. Similarly, you can provide transit service with less resources.
Considering how long the average concrete building lasts I'd be very surprised if single family houses were more efficient in the long run.
