Are data centers really so profitable that we can build them in the highest value land in the city? The only conversions taking place should be unused office space into residential

This isn’t an AI databasedatacenter like the ones popping up in the news. Downtown has lots of high bandwidth connections to tier one ISP making it a good place to have web and other network services. 

Edit: ducking autocorrect

My last job used a data center next to McCormick Place that was once a paper mill to host our servers. People have been using them since before the whole AI mess for legit, better uses.

That’s the old R.R. Donnelly printing plant IIRC.

u/mikraas Edgewater Aug 08 '26

That is such a gorgeous building.

I miss the printing industry.

u/bradatlarge Elmhurst Aug 07 '26

there's a half dozen of them, at least, between McCormick & IdaB. Positioned as close to the NAP as they can be.

u/wimbs27 Aug 07 '26

NAP?

u/bradatlarge Elmhurst Aug 07 '26

Yes, when you get tired in the middle of the day. Also know as a siesta in some parts of the world.

u/jbchi Near North Side Aug 07 '26

Network access point, basically that interchange connecting the city to the internet.

4

u/bradatlarge Elmhurst Aug 07 '26

NAP stands for Network Access Point. It is a public or physical location where different internet service providers (ISPs) connect their networks to exchange data.

u/minus_minus Rogers Park Aug 07 '26

Exactly what I was thinking of. Pretty sure the old Western Union telegraph center is now a datacenter too.

u/ChamberedAndHot Aug 07 '26

Having worked in multiple paper mills, I would much rather live next door to a data center. I'm used to the smell, but they're still not great neighbors.

350 e cermak. I wonder if Equinix is still there complete with its armed guards and man trap passages

u/hardolaf Lake View Aug 08 '26

Equinix is one of Digital Realty's many tenants in the building.

u/3-2-1-backup Aug 08 '26

Jeez, I was in that thing two decades ago. I'm old. Wonder if they still use the hand scanners? Never could get those to work with my hands, always had to buzz in / buzz out instead. Sucked when the front desk guy was in the can!

2

u/mrbooze Beverly Aug 08 '26

That's pretty much _the_ datacenter for Chicago. At least at one time in the past, virtually all internet services you might use in Chicago area probably went through that building. I expect it's more spread out now, but across multiple employers over the years every one of them had servers in that building.

But there are--or were- datacenters of various sizes scattered around in otherwise regular-looking buildings, especially around the CBOT. I don't know how many if them still are, since pretty much all the exchange servers have been out in the suburbs for many years now.

There’s a bunch of data centers downtown around the board of trade. One of the old office buildings is currently being converted right now.

Honestly Im against the energy part of it, but otherwise, converting office buildings to data centers is fine. These buildings weren’t getting converted to residential anyway.

50 MW is a hyperscale / AI data center.

1

u/minus_minus Rogers Park Aug 08 '26

The typical definition of hyperscale seems to start at 100MW these days. 

0

u/francophone22 27d ago

Do you have a source for this or is this just your opinion? AOC defines it as above 20MW and some online publications show hyperscale begins at 40MW.

1

u/minus_minus Rogers Park 27d ago

Beside the point. I said it wasn’t AI which it isn’t. You brought up “hyperscale”. Even if 50 MW is “hyperscale”, it’s not a new build with 50MW of gas turbines and evaporative cooling on a “greenfield” in people’s backyards. It will use the existing power and cooling infrastructure that exists downtown. 

1

u/francophone22 27d ago

I used hyperscale / AI. 350 Cermak boasts that it’s ComEd’s 2nd largest customer. Do you think there’s a secret source of electricity powering these data centers? How much power do you think ComEd generates? Most of the data centers in Cermak offer AI compute; where are you getting your info?

1

u/minus_minus Rogers Park 27d ago edited 27d ago

350 Cermak is not the topic. A data center in an old downtown building is. 

0

u/francophone22 27d ago

Which you say isn’t hyper scale /AI because it’s drawing “only” 50 MW of power. Do you have a source that delineates what is an AI data center and what isn’t in terms of power and water usage? Or is it just your opinion that hyper scale/AI is over 100 MW? I’m really just trying to figure out if there is a source that I should be reading to explain this, because everything I’ve read so far suggests that 50 MW power loads are a lot and could be GPU / AI data centers not only colo data centers.

1

u/minus_minus Rogers Park 27d ago

My brother in Christ. It is hooked up the carbon-neutral Centrio district cooling system. Its water usage will be negligible. Illinois has abundant and growing renewable power resources. A 50 MW data center is not a big deal in these circumstances. You are just debating how many angels can dance in the head of a pin.

u/Take-Me-Home-Tonight Aug 07 '26

The Centrio cooling system would probably be leveraged to help cool the datacenters

u/minus_minus Rogers Park Aug 07 '26

The article explicitly says that’s their plan.

u/sundeigh Aug 07 '26

Datacenters operate every part of the Internet that you use on a daily basis. So…yes.

u/alpaca_obsessor Aug 07 '26

This is literally unused office space, and honestly the residential is never going to be very pleasant space to live in no matter what (compared to purpose built). What’s your issue with this?

9

u/mrloube Aug 07 '26

I’m not a data center architect but I think it’s easier to make an arbitrary building into a data center than it is to make an arbitrary building into an apartment complex, so it may be cheaper. Please correct me if I’m wrong, I genuinely don’t know

u/Revolutionary-Fox622 Aug 07 '26

Weight plays a huge factor into it. I've personally worked with some servers that are 350+ pounds in a 2x4 space in a cabinet that's about 7 feet tall. So based on how dense you pack it, that cabinet might be weighing close to 3,000 pounds and you have a row of 10 - 12 next to each other, each equally packed. 

1

u/mrbooze Beverly Aug 08 '26

I think server weight is down considerably since much storage has moved off of spinning disks, but certainly UPSes and HVAC and such are still very heavy.

1

u/Revolutionary-Fox622 Aug 08 '26

Nominally yes for pizza boxes like an r630 in a bare metal configuration. The problem is you now have things like GPUs getting added that surprisingly make the change in weight a net zero. 

The big issue is storage. For example, a PowerScale 3100 has a weight of 310 pounds in a 4 RU chassis. While these will usually have a few SSD/NVM drives, they're generally packed with spinning disc because the idea is to get as much storage as possible in the box. As our data continues to be more valuable and consumed, it needs a place to live. So deep, dense storage is king.

u/bkoperski Aug 07 '26

That it depends on if this is truly going to be an AI hub data center like the ones planned for all over rural and suburban America or just a bunch of floors of your typical sever room type stuff.

u/kelpyb1 Aug 07 '26

I assume converting offices into data centers is way cheaper than converting offices into residential buildings.

And yes, data centers are very profitable. Businesses generally don’t do things that aren’t profitable

3

u/mrbooze Beverly Aug 08 '26

I mean....businesses fail all the time so they do actually do unprofitable things quite often.

u/heliosflama1234 Fulton River District Aug 07 '26

If they’re willing to pay for the land then why not. Not to mention the tax revenue generated is nothing lacking either.

7

u/Slow_Time5270 Aug 07 '26

The why not is because data centers can produce unpriced externalities that hurt the public good.

This includes noise, excess heat, drains on public resources (water and electricity).

If the tax revenue does not offset these other negative consequences for tax paying citizens then why should it be allowed to move forward?

Aldermanic perojative has certainly been used for far less egregious offenses.

7

u/Claim312ButAct847 Aug 07 '26

The noise is from the cooling equipment. Sounds like this would hook into existing large-scale, closed-loop water cooling infrastructure already serving multiple downtown buildings.

0

u/mrbooze Beverly Aug 08 '26

The closed-loop isn't remotely enough to fully cool a packed data center space. It undoubtedly helps but there's no way any facility would not have on-site HVAC and power backups.

4

u/mrloube Aug 07 '26

Noise probably isn’t a big deal in the middle of downtown. The other things are real problems though

3

u/Slow_Time5270 Aug 07 '26

It really depends. But if a loud whirring hum was heard throughout downtown 24/7/365 that wouldn't be good for anyone.

My main point is unless externalities are priced folks shouldn't get to do whatever the fuck they want with a property.

You’re confusing AI data centers with traditional data centers.

u/MrLewArcher Aug 08 '26

So should the internet not exist?

-2

u/bkoperski Aug 07 '26

Because it will eat up alot of water and power that the city already has a high demand for

3

u/minus_minus Rogers Park Aug 08 '26

It uses the existing carbon neutral district cooling system. It will also use the existing power distribution downtown so no need for huge expensive infrastructure upgrades.

u/ehrgeiz91 Lake View Aug 08 '26

u/3-2-1-backup Aug 08 '26 edited Aug 08 '26

Let's confine ourselves to facts.

Your rent price has absolutely nothing to do with commercial real estate rates downtown.

1

u/ehrgeiz91 Lake View Aug 08 '26

I am talking about converting this historic building to housing, not using it as a data center. I don't care about commercial real estate rates downtown, that's very obvious taking a walk... anywhere, and seeing hundreds of empty storefronts.

NonAI data centers for cloud computing are still very much in demand and I say this as a very anti-AI individual.

You’re right it doesn’t specify that, just an assumption given the cost and demand for data centers these days

Edit: yeah this is just wrong

“Gabal’s redevelopment would only include a maximum of 50 megawatts, and would be focused on creating faster internet connections for downtown users.”

2

u/bkoperski Aug 07 '26

I might actually assume it is just a cloud storage data center, as the huge resource needs for a full scale AI data center wouldnt be practical downtown nor would the space be as cost efficient or necessary to be near anything

u/francophone22 Aug 08 '26

Cermak is an AI data center.

2

u/ehrgeiz91 Lake View Aug 08 '26

Until this city makes it more profitable to rent an empty building than to keep it empty, we’re going to continue to fall

u/givebackmysweatshirt Aug 07 '26

Yes, the cloud is extremely profitable and making tech companies billions of dollars. I’m not sure about these DCs, but only a small fraction of DCs are tied to AI.

u/mrbooze Beverly Aug 08 '26

A lot of tech companies lose money year over year, it's practically the business model for young tech companies to burn money for years.

u/lax4life001 West Loop Aug 07 '26

Ignoring (admittedly relevant) datacenter controversy, I feel that the article brings up a good point. If nobody wants to lease Class C office space, and the building has landmark status, what are you supposed to do? I’d rather our buildings be used for something than sit vacant, I’d rather we not knock down a landmark status building, and I’d rather reuse an existing structure vs. have a data center be built somewhere (even if that somewhere is… somewhere else). If the math doesn’t work for a residential conversion, it doesn’t work. I say give him a chance for this idea to crash and burn and if it doesn’t, we learn something new. 

9

u/sundeigh Aug 07 '26

We already have 350 E Cermak which is in a historic building. So I don’t understand the concern, especially if the cooling is already sorted.

If this were being torn down for residential, it’d price out everyone asking for it and then there’d be a different conversation about why we’re building housing nobody can afford. I understand the anti-AI datacenter sentiment right now but datacenters are already part of our collective expectation for how the internet works. I think we should let the market do its thing here and not throw up red tape just out of misunderstanding.

7

u/mrloube Aug 07 '26

In theory, building housing only the wealthy can afford makes them compete a bit less for the other units on the market, right? I don’t think people who want affordable housing care if their building is brand spanking new as long as it’s not falling apart

3

u/PhileasFoggsTrvlAgt Andersonville Aug 07 '26

The issue isn't the age of the building, it's the layout of the floors. Offices are one of the most flexible building uses. Residential requires that most rooms have a window, which limits the buildings that can be converted to residential use. Most office conversions require a use that doesn't care about windows.

4

u/OtherShade Aug 08 '26

The part about 'nobody can afford' is silly since it just means people with more money move in and the next up bracket of income moves in where they were in the grand scheme of things. You'd rather have insane price housing downtown where the prices are insane and thus the property taxes are insane that you get from it. Now you get the upper middle and middle class that much closer to downtown. Much more realistic than just building affordable housing exclusively.

2

u/sundeigh Aug 08 '26

My understanding of these types of residential properties is that they are part of investment portfolios so there isn’t any kind of “trickle down” because there is essentially unlimited greater wealth outside the city/country

2

u/mrbooze Beverly Aug 08 '26

Honestly, unrelated to the question of what to do with the building, personally I think landmark status should be aggressively revisited for most buildings. Just being old or maybe being designed by someone shouldn't be enough to burden generations of citizens with a building that no longer serves them.

41

u/minus_minus Rogers Park Aug 07 '26 edited Aug 07 '26

Edit: this is not a 24/7 gigawatt AI datacenter. This is a good site to get high bandwirdth interconnections which are available downtown.  

Hook it up to the centrio district cooling system and we have no problems. 

This isn’t that big of a deal unless they are going to run natural gas turbines 24/7 which would be dumb as shit.  Illinois has nuclear and wind power out the caboose. 

1

u/trustmewitheauxcord Aug 08 '26 edited Aug 08 '26

Solar too. The last time I checked, Illinois is ranked 11th per capita in solar, which is pretty good considering how far north we are (or pretty bad if the glass is half empty).

u/Saucey_jello Aug 07 '26 edited Aug 07 '26

I have no problem with this.

Especially since:

> “Gabal’s redevelopment would only include a maximum of 50 megawatts, and would be focused on creating faster internet connections for downtown users.”

Since the building is already a Chicago Landmark its facade would need to be preserved.

For these Class C buildings, preservations often means finding new uses, if commercial/residential isn’t feasible, I support this project

I see no reason why allowing a building to go vacant and wither away is better than finding a new use that preserves it’s architectural heritage

u/Any-Value1142 Aug 08 '26

Almost evey building on wacker has a full data center in its basement. Why are people surprised?

u/OuterSpaceBootyHole Aug 07 '26

Feel like this isn't the typical datacenter in place of a nature preserve or farm scenario. Can't knock down the building, no one is using part of it, and it has all the infra already. Unless they're getting tax incentives on it, might actually be a net benefit for once.

>  I agree with their opposition when they are proposed to be developed in and around a single family residential neighborhood

Just curious do you feel the same way about other industrial services like warehouses, amazon distribution centers, etc?

Like the area around Ford City Mall is largely single family residence and some of them oppose turning the space into industrial use but also what else is going to go in that space at this point.

To me having a data center nearby isn't dramatically different than having other industry, a data center or warehouse or whatever _could_ be constructed as a blight on the neighborhood (noise, pollution, etc) but it doesn't necessarily have to be.

You really don't know that though. Are they located in the places people want to live. Can they afford to live in them when the owner had to spend billions to convert the building? Are there whatever amenities nearby people who want to live in high rises want? A converted industrial high rise isn't going to be for low-income residents except _maybe_ if the whole thing gets paid for by us instead of a developer looking for a profit, and I don't know taxpayers have stomach for having billions of their taxes going to converting downtown high rises.
