Definitely not the biggest "district heating" type system in terms of power Westin Building Exchange in Seattle has far more megawatts being pumped right next door even. And not the only one (just the only one I'm directly aware of). Theirs is probably unique though in that it is residential areas instead of businesses.
Door code at 5:11 is ??2580. I'm surprised how easy it is to get inside such a "maximum security" datacenter. Wouldn't be possible in a real high sensitive area. It's just for the good show imho. Anyway nice location for a server and interesting insights.
I think he is using a rfid tag at first and then entering his uniqe access code or the doors uniqe code, but either way it not very smart to show the code because in theory it could be copied but it would be quite hard in practice. Oh well it is still a cool place and they have probably changed the codes since 2014 if not I don't think they could call themselves a secure IT company.
A place that holds sensitive information typically illegally has better security than that trust me. He's aware a camera is following him so it was probably a one time code created for the video.
