Also, it was alluded to in the article, but most of the individual stores in the mall have separate HVAC systems which include heating.

They don’t actually run the “AC” in winter, like you might think. Air conditioning in large spaces is much more complicated than a residential system, and much of this is due to ventilation and humidity control requirements. At Mall of America, they have a complicated automated climate control system that monitors all aspects of the interior AND exterior climate conditions and responds accordingly. If the building gets too hot in winter and the outside conditions are acceptable, the air handling systems will pull in outside air and vent inside air. They will rarely use mechanical cooling unless the outside ambient conditions are unacceptable (for instance, too humid).

Running the a/c in winter makes no sense because you can just open the doors and passively vent the warm air up through vents and opened skylights.

This is how Boeing heats up the largest building on earth (by volume). The Boeing manufacturing plant in Everett, WA has no heaters, just those huge lights that keep the place warm in the winter.
