I noted that Arthur D. Little says a large
hospital consumes about 1 MW. Here is a mega-mall example of power consumption:
". . . São Paulo is truly an all-in-one complex.
The 1.75-million-square-foot complex includes the
state-of-the-art WTC Business Tower, the elegant
Hotel Gran Meliá São Paulo WTC, and one of Latin
Americas most upscale malls, the D&D shopping center."
It consumes 5 MW at peak, which is the most I
have ever heard of for this kind of facility.
That is as much as a small city. This is, "one of
the largest commercial buildings in the world." It was built in 1995. See:
