Do you seriously believe that an opening the size of two panes would suffice to remove 1 MW of heat from the mezzanine? A fan large enough and powerful enough to do this would blow the other panes out, but that still would not be a large enough opening. If the inlet were at the same window, it would suck in hot air. You would need large, prominent ducts to prevent that. Does your mystical child see such ducts?
The whole story is preposterous.
Jed,
This would require "make up air" also, so whatever amount of CFM being moved out of the window has to be made up with outside air from another source.
Also, to affect this amount of heat transfer, (1MW), their must be a GIANT delta T between the outside air and the inside air, (it varies greatly in Miami from day and night).
