I read the article closer and can see why there was no air conditioning. If the utility looses a phase the A/C system can not operate. IIRC this is typically a 460 volt system three phase. It sounds like a Chill Water A/C system. A central chiller cools water which is pumped through a closed loop to air handlers where air blows across the coils. I doubt seriously their generator was designed for or used to power that system and that is a nation wide normal. The criminal part would possibly be a lack of seeking evacuation.

These type of systems will go down. If for example the unit tore up requiring a couple days repair there is a work around which is bringing in a flatbed tractor trailer with a portable chiller on it and hooking it up using the buildings electrical system and chill water loop. It takes 4-8 hours to connect such a system especially if it has not been done at the facility previously. You also have to allow for transport time as these type of units are limited and only in larger cities. Ours came out of Atlanta 4.5 hours away when we needed it. I think Miami also had one but under these conditions would be useless as it was an issue with power coming to the building. Under hurricane conditions I would expect a local utility would loose partial or all power. BTW local utilities are well aware of these facilities and their power demands and special requirements.
