3000W grow heat?? +rep for help

Hey guys a friends in the process of setting up his flower room.. He has roughly 20x20x9 foot room to work with.. He has done this before but with only 4 600w lights so heat wasnt an issue.. What he was wondering is if he had 3 1000w hps with very good air flow in and out of his sealed room.. Will heat be an issue? Or is he going to have to invest in air cooled hoods to keep temps down?.. He doesnt want to have to have an AC running as he is allready worried about the power usage...
I know its a bit of a "how long is a piece of string" kinda question but any help i would be very thankful

I'm running 3x1000w hps in air cooled hoods, but this was in a 4x12 space. AC is a necessity. Without AC I was getting like temps above 90degrees. I'm no expert though, just thought I'd give my scenario. Hope it helps.

basements are the best but if you dont have one run your lights at night and draw fresh air from outside at night

HID lighting puts off a certain amount of BTU's per watt, about 3.4 BTU's. I don't think that an additional 2,040 BTU's is going to push the temps in a room that size very much. If 2,400W wasn't a problem I don't think that 3,000 will be. I think that it what plsfoldthx was talking about.

How do you have good airflow through a sealed room? If the room is "sealed" there is no airflow......

Tell your "buddy" he's better off getting air cooled hoods and using a smaller room. 3000w divided by 400sqft= 7.5w/sqft...sure hope "he" doesn't plan to fill this room with plants.
