I would assume it takes far more energy on heating/cooling/ventilation systems for large buildings in general than it does for a series of small buildings that have classic ventilation systems called "windows that open to let in fresh air." Something that is pretty rare in office buildings.
EDIT: Furthermore, large buildings usually have automated systems that keep it roughly the same temperature throughout the whole building while individuals in their own homes might try to keep heating/cooling bills low by choosing to only heat/cool specific rooms that they're actually physically using. I know I certainly do this at home, no sense in doing temp control in a room no one is occupying (other than making sure it's above freezing for pipes, etc.).
I once worked in a high-rise office that would get uncomfortably cold (for me) in winter. I thought they were just being stingy with the heating, until I went into the office on a Saturday and found it was pleasantly warm. Turns out all the computers were keeping the office nice and toasty, and they were actively cooling the place during the winter to keep things at a "business temperature."
