With all due respect, having worked on a large conversion, the elevators is the least of the problems. The real challenges are rezoning, different safety requirements, all new plumbing, electrical, ventilation, fire systems, loads, parkings….

[@TD32333]

Thanks for this comment. I was surprised when elevators were the subject of a video about the secret to skyscraper conversion.

[@juanmadrona7199]

I was thinking the same thing, in fact in the building they are talking about, you can see that the residential floors has a completely different design to the rest of the building. How is that an example of the conversion from offices to residential?

[@TrogdorBurnin8or]

I would imagine the utilities (supply and drain plumbing in particular) need to go in a lifted floor or a lowered ceiling? The offices depicted have plenty of headroom to accommodate that I suppose.

[@luigifranceschi2350]

@@TrogdorBurnin8or yes, for a conversion you need to have all the new plumbing redirected in the dripped ceilings. The issue is how to deal with the noise of such plumbing, and also how to deal with the space taken by the ventilation. The requirements of water, ac and electricity are completely different. As well as noise control. Unless you have already designed the building to be sectioned in residential units from ten beginning, it might actually be cheaper to demolish everything and rebuild from scratch. And by doing that you know pretty much well in advance how much you are spending, when instead you do a renovation/conversion of an exsisting office building into residential everything is a surprise. And the cost cannot be budgeted.

[@jj6282]

I was wondering. It must be a nightmare to convert offices to apts and probably cost prohibitive. There was a beautiful conversion in my neighborhood recently of a midrise, but it was stripped down to the elevator core, support beams, and floorplates before being completely rebuilt

[@andrethib]

as others have pointed out, there are a lot of issues with converting commercial space to residential space, it looks like this innovation addresses one of those issues. as I understand it, the reason tall, multi-use buildings require separate elevator systems is because of the varying levels of security/access required by commercial, residential and hospitality tenants. it looks like this system is really a "smart" access system that uses the same elevators to let people go where they need to go and restrict them from places they shouldn't go...a little more exposition on how the system does this would have been interesting

[@RandomUser2401]

if you know anything about elevators, you know that relying on them for safety and access control is a very very bad idea.

[@Klyis]

The issue here is that a smart access system only works if there is a single person using the elevator. As soon as you have multiple people with different access codes using the elevator at the same time everyone will have the ability to go anywhere.

[@szurketaltos2693]

@klyis -- there are a few ways to solve this. One is, just have additional badge access after you exit the elevator. Another is to disallow mixed security passengers on the same trip. I suspect some combination of both is the way to go.

[@AlphaGeekgirl]

[@jhoserovi29]

Because it didn't, elevators with dual openings are common, I don't understand why they had to make a video about it and try to make it look as if this was a revolutionary element in a dual-purpose building.

[@jerryklosek5589]

I think the idea is that if you enter from one side, ie the residential side, you know you won't have to make stops on the office floors and vice versa. Instead of the separate elevator concept of traditional mixed use building.

[@briankuhl9314]

That's because it is so simple it's stupid. If you open the door to the elevator from the residential lobby and go inside, the elevator will only go to the residential floors. If you open the ground floor door from the commercial lobby the elevator will only go to the commercial floors. Coming down it's the same concept, you get in on a residential floor, when you get to the ground, it only opens the door to the residential lobby. And visa versa for commercial space. So one set of elevators behave as if they were two sets. You go up and down and the elevator opens the right door for you, as opposed to traditional two door elevators where you could chose to open either door and go to any floor, or at least stick in a special access card to identify where you can go.

[@russellmoir2776]

[@Volkbrecht]

@@miroslavmilan It's actually a non-issue. Why would I care if there are office workers that enter the building through the same lobby and use the same elevators? As a resident I'd know that I'm in a multi-purpose building, and what to expect from that. The only real issue is unauthorized access, but that can be minimized by access-controlled doors at the residential floors.

[@geroutathat]

​@@Volkbrechtit's the other way around. Visited a friend in an apartment. It's shared. I was blocked from the bank and companies using the building. In office buildings that allow people off the street to just enter, you usually have to pass a security desk at the bottom, then each floor has a lobby. If you get off at the wrong floor you usually get flagged by security. Lots of the floors will be totally closed to the public so stepping off in them without a bade causes a security response. Sure you could just open the whole building up totally to the public, but then no companies will rent there.

I would have thought the biggest challenge skyscrapers face when turning them into residential would be the lack of sunlight by the cores and therefor apartments would almost have to be entirely open plan with the kitchen and toilets close to the core and then just one huge open space for the rest of the flat?

[@TheLiamster]

That’s true in some buildings. Also utilities and insulation for office buildings is different than residential buildings

[@jpdemer5]

That's the primary problem in NYC, where there are laws mandating the presence of windows in all rooms. Most office buildings have windowless rooms in their cores. As pressure to convert buildings increases - the real estate industry is nearly omnipotent - I expect that these laws will be modified.

[@lwilton]

Interesting. When you mentioned 'the biggest problem with converting offices to residential' my first thought wasn't elevators. It was plumbing. Most people renting a high-rise apartment probably aren't going to be happy with a shared bathroom at the end of the hall. They probably also want at least a minimalist kitchen with a sink containing a garbage disposal. This is A LOT of plumbing, and it is now distributed all over the floor. How is this going to be handled? You are likely to have to increase the size of the water supply, the size of central water heating (perhaps per floor), and greatly increase the number of and capacity of sanitary drains to deal with the multitudes of showers, toilets, and kitchen sinks. I think an article on how this can be done would be interesting and useful.

[@Khotetsu]

As others have pointed out, sunlight would also be a huge issue, as offices have large amounts of windowless space while there are building codes that require a window in every room in housing.

[@pali2944]

or you could just say the biggest problem of turning offices to residential flats is the cost of turning them into residential flats. this whole elevator topic was a clickbait

[@s._3560]

Or balconies, gardens or parks and supermarkets, places of worship, childcare and other family amenities, children playground, schools and nature etc. Not everyone wants to live in the city centre of skyscrapers. It is more soulless, cold, corporate, transient and stressful. Maybe single people or childless couples who work most of the time and have no life. Families actually prefer suburbs, leafy green spaces to relax in, individual houses and gardens. It is a more cosy and family oriented place.

[@adriandunne4382]

It can be done with modern vacuum sanitary plumbing originally developed for cruise ships but now commonly used on land in prisons, hospitals, stadiums, and high rise buildings. Plumbing can be in the ceiling and toilet fittings use a fraction of the amount of water that standard fittings do. They can also be moved about easily if needed.

[@cod-the-creator]

So I'm confused, the reason you can't take a normal building with normal elevators and turn it into a residential tower is because people would "feel like they're in an office" - whatever that means... ?

[@rennycepeda6576]

[@captainteamcarry3]

There are different codes and requirements for residential and commercial construction projects because both spaces are used in vastly different ways by vastly different people.

[@doyourbest7655]

Kitchens need exhaust, bathrooms need separate exhaust, plumbing vent and drain, lots of them. windows for each room. The overall footprint is more suited for large openness so light can get to each desk. Residential is small rooms unless it’s a youth hostel or military dormitory. Some buildings could work others too awkward.

[@bitslayer42]

In New York there are additional challenges in converting office buildings to residential, because of the differences in building codes. The residential codes require a window in every room, while office workers were never afforded that. Many modern office buildings have huge floors, that used to be filled with little cubes. That doesn't work as bedrooms.

[@MaxMatti]

In Germany natural light is required for workplaces, so the us-typical cubicle system would not be legal. But other than that I agree. You would need permits and put up (or tear down) walls and reroute plumbing, depending on the exact floor plans.

[@MuslimComputerTuts]

I have a friend of mine who used to be a property developer (now retired). I asked him about commercial real estate investment over 15 years ago and he said "I never invest in commercial real estate, only residential" I asked him why? He promptly said "because people will always need a place to live". Those words are even truer today.

[@maxmeier532]

that's nonsense pretty much. It's like telling you the lottery numbers from last week. it's all cycles. Commercial real estate was making good money, people built a lot of it, so the market offer increased, demand naturally and by chance (pandemic) decreased. Living spaces was making okay money, it wasnt built as much. Inflation was low, interest was low, also if you went in debt, so more and more people were able to finance their own home. Which increased both sales prices and rent prices, first one because demand increased and the second because sales price informs the rent, as every investor has a ROI he wants. Additionally, many people moved to the jobs which are mostly in already dense regions obviously. Immigration mostly from south to north (globally) put more pressure on the market. Now more and more living space is being built, interest is high again and prices for buying and renting real estate are already stagnating and partially decreasing. Not only did businesses move out of cities, so did people. And because of all that, a lot of people who financed real estate with only short term guaranteed interest rates at super high sales prices will be effed. Not as bad as during the last crash some 15 years ago, but still.

While going over various elevator setups is interesting, this seems like a minor/tertiary issue when you are supposedly asserting to have 'solved the empty skyscraper problem'. There are just so many more significant barriers to changing a commercial tower into a mixed use/residential tower than getting a more efficient elevator service design.

[@holger_p]

No, there are just more equally ranked problem. Lot's of details, but nothing really complicated. Modern Underfloor-shower might be the only thing, that goes into the floor itself. And that's the only thing you have to keep. Floors and outside Windows.

[@BurningTrapezoid]

So just that I get this correctly: The actual issue here is that you want seperate lobbies for some reason, right? Because if you had a mixed lobby, there would be no issue with the elevator. In the video it is presented like an obvious fact, that work and residential people have to be completely separated but to me that really isn't obvious. Maybe I am missing something here. I think as a visitor I would find it quite confusing, if I had to use different entries for different floors. Also, do Visitors also need to install an App to use an Elevator of a Building they are just visiting?

[@robertopontone]

Sorry, but actually although potential interesting, this video did not explain anything on how this new concept works. A lot of big words with a little meaning.

[@tristan7216]

I love that they think the big reason we can't use empty offices to solve the housing crisis is that executives don't want to ride with the poors in elevators. If only it were that easy, i suspect it has much more to do with the plumbing (one bathroom per floor in an office building vs 1-2 per apartment and a kitchen too) and the large amount of windowless interior space of large-volume office buildings. If you didn't build for dual use, retrofitting is expensive and may just not work at all.

This solution has actually been around for a while, although this may be the first new construction to use this technique. I remember presenting smart elevators in one of my presentations back in undergrad and that was lets say a few years ago. But I know some buildings in Japan are using a similar system to some success. But here in the US, the problem is more so the plumbing issue rather than the elevators (I am not sure what they are doing about that, but the number of office tower conversions is going up, especially in NYC). Nice tech all the same although I am not sure how much I would want to rely on my cellphone for building access.

[@szurketaltos2693]

Plumbing and floor plate size. Some of the larger floor plates require some way to get more light to the core, either by adding a courtyard ($$$) or changing the rules to allow artificial lighting in bedrooms. I suspect the other utilities (including elevators) are also tricky, but probably not nearly as bad as those.

[@DeanStephen]

Fred, I read an article a couple decades ago about challenges to office building conversion. At the time the thinking was that the biggest challenge was insufficient floor height to allow for retrofitting the plumbing required for residences. Has this been solved?

[@danjelowitsch]

The challenge is actually the other way around. Office floor-to-floor is typcially higher than residential due to taller ceilings. When building for dual purpose on day 1, the residential floors would come in more expensive as they would be built with a higher floor to floor than typically required. Advantage is to be able to run plumbing and services in the resulting ceiling void, but comes at a cost due to added structure and facade that a purely apartment or hotel building wouldn't need.

[@jv-lk7bc]

@@danjelowitsch thats true but with the rediculous mismatch of vacancy rates to need, the improved revenue from making it mixed use would almost certainly dwarf any extra cost - and in the case of all the existing commercial structures, the cost was already built in. Plus a lot of extra uses for taller spaces in residential are possible.

[@adriandunne4382]

Yes, the solution is vacuum plumbing which is used on ships and aircraft and in many large buildings such as hospitals stadiums and hotels. The manufacturers of these systems have websites. Another advantage is that vacuum toilets use much less water than normal fixtures.

The new Ritz Carlton tower in Mexico City works similar to this. The hotel has apartments, offices, hotels, commercial space and restaurants. The elevators have multiple doors depending on where you want to go. The car garage is also pretty impressive as it stores the vehicles via a lift system.

[@danielschein6845]

In most office to commercial conversions, the elevators are the least of the problem. Think about the last big office you worked in. Picture where the bathrooms were. That’s the only place on that floor with plumbing. Once you break up that floor into apartments, every one of those apartments needs running water, separate heating/AC and other utilities. That office building you are imagining probably doesn’t have space for this. In many cases it’s cheaper to tear it down and rebuild than to convert… unless it was designed from the beginning to be modular. Most skyscrapers aren’t designed that way.

[@s._3560]

And people moving into those apartments might be making a lot of noise. Are they going to be just serviced apartments for short term rent? Because they can't be long termed since if individually owned, people might want to do some renovations to it, then what about the noise?

[@adrago17]

I would have thought there were more significant issues with residential/commercial flexibility being the building services requirements...

There are. Office buildings in DC are being converted to residential use, and they have to strip everything down to reconfigure the plumbing, the electrical wiring, the layout, etc.

[@robinholmes785]

Plumbing (drainage & water lines) would also be a huge challenge , particularly if you’re looking at an existing building. Elevators are used like a bus not a car, multiple floor stops. You are back to needing large numbers if they don’t stop on every floor?

[@kaitlyn__L]

It seems they do serve every floor, unlike the example with adding extra shafts. If no one is using the residential lobbies all of the lifts can serve the office lobbies, and vice versa. It’s just that, on a per lift car basis, if they’re currently serving a residential floor in that moment they don’t seem to take on anyone from the office lobbies. (It’s unclear if that even includes people who live in the same building going home from work, or if an exception is made based on the destination.)

[@Khotetsu]

Each elevator seems to be designated to a specific use based on demand by some sort of computer system linked up to an app on your phone. Its not really explained in the video, but I saw other people saying that you walk into the building, and the app tells you which elevator to go to. If you're going to a floor of offices, then that elevator won't stop at any residential floors on its way up, even if people on the apartment floors call an elevator, and vice versa. It's essentially just a keycard system hooked up to a computer that computes demand and assigns elevators accordingly, but uses an app on your phone to tell you which elevators to use. Since the apartments in this building divide the office spaces into 2 sections, it would be interesting if the system could further designate between the 2 sets of offices to essentially act as "express" elevators to the upper offices, but there's no mention of that in the video. I still feel like the elevators are one of the lesser issues in converting skyscrapers though.

Our group does a lot of work on high rise apts and offices in Houston. Most towers are single purpose, or converted from office to residential. Mixed use is extremely rare. Doesnt seem like there is enough demand.

Seems to be a really new thing to the new world. It's the default in Europe. Ground floor is shops, first floor is doctors, lawers, small offices, and above is residential.

You are increasing the building costs for both to handle both. 2) Commercial prefers new build since they are taking out a loan anyway 3) Commercial likes to build to their own specs, so another reason for new build 4) We need so much new housing, there is a housing shortage, so why would we ever then switch from residential to commercial? 5) And in most US cities they'd need to come up with a new building regulations to make this legal

I’m not sure if these are lobbies or communal office space he is filming in, with the 3m high ceilings and windows, but in modestly sized apartments, the big issue in office conversions is always having just one wall with windows, meaning your bedrooms and office are in the central part of the building with no view to the outside. After that, the problems are plumbing, hvac, electric etc.

Why is it the issue if lifts are used for both residential and office spaces? I assume there may be privacy/safety concerns.

Wouldn't this be enough to start using empty office space as residential?

Canary Wharf is emptying out, but I've noticed that the City of London is more bustling than ever, with firms like HSBC even relocating their HQ from Canary Wharf to the City.

Elevators with 2 doors have been around for a while. Keycard access for different levels has been around for a while, too. With 2 or 3 different levels of keycard security, the elevators could be programmed like this without need for an app. When I played Sim Tower as a kid, I assumed a lot of tall buildings had a mix of office and/or residential and/or hotel. When the Book Cadillac hotel in Detroit was re-opened in 2008, it had condos on some of the upper floors.

[@yay-cat]

Wait how are residential lifts different from commercial ones? Just a back door opening and you don’t want strangers to have access to your house?

[@profwaldone]

If I understand it correctly. Every shaft has 2 entrances a front and a back. If you press the call elevator on the front the elevator will only accept inputs that bring you to front access floors (in this case commercial) And if you press the call button on the backside the elevator will only accept inputs for floors where the backside is available. This also prevents unwanted ride alongs as the elevator won't allow the frontside to be called or opened while it's in backside use. It's pretty clever and could easily be expanded by having a second lobby floor only accessable via escalator or something which allows access to another 2 subsections or the building. Or you can split/combine the shafts as you see fit. (though it requires some rebuilding of the ground floor)

[@danmcnamara3287]

The biggest challenge in converting to residential is the plumbing risers for kitchens and bathrooms, and the ventilation shafts or risers required by code. These are traditionally close to the core as well and not located near the curtain wall. Bizarre that this video gets so excited about elevator operational controls as a sweeping remedy.

[@kameljoe21]

So many problems with this, yet many can be addressed. Most of the problems are going to be how residential and commercial can seamlessly work when each require a lot of changes. Residential requires several things to work. Bedrooms, living rooms, bathrooms/laundry rooms and kitchens. If you were to build the offices in such a way that you could change a floor in to a set of an apartments in no time flat. Most skyscrapers are around 200x100 feet or 20k square feet. If you were to ideally say that each apartment was 1500 square feet and the last 5000 was elevators and hallways. You could set up a 10 apartment/office floor that would have 3 bedrooms 3 baths. If done correctly you could ideally still have 30 offices and large open areas. Think of the bedrooms/bathrooms as being window rooms while the living/kitchen areas are the middle with window ends and the center the elevator/stairs and hallways. This would create a square type area when it was opened up. The plumbing could be sealed off at floor level and the vent sealed in the ceiling. With in the ceiling would be the firewall sections where the apartment walls would be and they could be slipped back in. It would only take a small amount of work to remove the ceiling panels and the the cross members for those panels where the walls are then they connect back in and new shorter panels and shorter cross members are installed back in. The only problem with this is the amount of waste one is going to involve in fixing up these floors and then ripping them out at some point. Office space is going to become obsolete over the next decade when more and more companies are going to down size their staff or grow their remote staff. AI has and is taking over more and more office jobs and people are finding ways to move to new sectors. The push back for working in offices is really getting hammered down to employers as people are no longer wanting that 9 to 5 crap. The internet and their speeds offer 4k video calling that is far better and gets even better by the day. People are no longer wanting to spend the hours driving to work when they do not need too. Countries should be pushing their companies to offer more remote work. Even if you have to live stream 4k during working hours. Its not that hard to have a computer with a screen streaming a group of workers working.

[@Brendissimo1]

I was figuratively scratching my head for this entire video until you revealed the sponsorship at the end. As others have said, the elevators are only a minor part of converting from office to residential use, or mixed use design. Far more important are things like the shape of the building to allow natural light, redundant utilities for easier future conversion between uses, etc. I assume this tower in Frankfurt has these elements as well, or else converting office floors to residential use in the future would be just as difficult as converting any old office tower currently is. Also, I don't believe this elevator technology is particularly new. Frankly, this video is below your usual standards. I don't feel I learned anything from it. If you wanted to do this sponsorship you should have integrated it into a larger piece about future planning for easier conversion between uses.

[@alfieakaronaldog]

I did not understand that at all! I get the two lobbies and two doors, but what if the building has three uses? Does the lift have no buttons? How does it stop people from the different uses being in the lift at the same time? What happens if residents want to go in and out at 9am or 5pm when everyone in the office is using them?

This reminds me of the old classic, Simtower. You could change the floors that elevators stopped on based on the time of day and which area, condos, hotels, or office and fast food was most busy at a given time, but it seems that you had to change the elevators when you needed and couldn’t enter a weekly schedule of changes before hand. It got tedious.

[@michaelpjeffries1521]

First the elevator shaft was built in anticipation of elevators being designed. It was expecting round cars with multiple doors controlling traffic from centre outward in whatever works for application of buildings intended use.

[@DanFrederiksen]

Also I think many office scrapers should make for quite decent residences. Tall ceilings, big windows. Seems rather compatible. Just needs a bit different plumbing but should be quite solvable. Maybe some kind of semi advanced walls so building weight limits aren't exceeded by putting in cinderblocks.

[@publicacct5626]

Plumbing somehow needs to be routed to every unit instead of a just a handful of restrooms. Same for electrical, and HVAC. Along with finding the space for that infrastructure. Then you have to consider emergency egress routes, access to natural light, soundproofing between units, parking, etc. These are the challenges facing office-to-residential conversions, not elevators lacking an app...

[@kaitlyn__L]

@@publicacct5626plumbing yes, but is there really that much electrical rework? For a 110V system I can see routing higher voltage lines for the oven and dryer and that, but in 240V country that should be fine right? (Maybe having a couple of high current ring mains has spoiled me, pretty much anything can be plugged in anywhere. The oven could go in the socket for the lights next to it and be fine.)

[@DanFrederiksen]

@@publicacct5626 both access to natural light and emergency exist are not issues in a glass high rise. And office buildings typically have quite a deck height for utilities. I don't see the problem, it could actually be quite good. If the building has zero parking that might be an issue but do they... whether office cars or personal cars that might be even as well.

[@publicacct5626]

@@kaitlyn__L Yes Kaitlyn it all really is that much work. Looking at your example of electrical: voltage isn't the issue (the US has 240v, just split-phase), this issue is current draw. All those stoves and dryers need to be on a circuit that can support that much current passing through it without overheating, and be wired to have a breaker if it does. You definitely cannot plug an oven into the same outlet as a lamp - one is a 15AMP circuit, the other is 50AMPs. Never mind the differences in outlet design. While you're at it you'll need to ensure every unit is wired separately with their own meter unless you want everyone sharing one electricity bill. I'm not an electrician so I cannot comment further here. Point being there are ton of things the average person hasn't considered when the "ooh make offices buildings into apartments" idea crosses their mind. Any research I've done on the topic suggests its often extremely difficult and expensive. I suggest you look into it. There's a reason you only see these conversions in very rare instances while property owners take huge losses letting their downtown towers sit empty for nearly 4 years.

[@publicacct5626]

​@@DanFrederiksen It's very dependent on the building. But access to natural light is absolutely not a given. Of the highrises I've worked in, you would be lucky to have a desk where you can see a window. The simple reality is office towers are often built with a larger floorplate than apartment buildings.

[@flipadavis]

I don't get it. How is this any different than just any old building having one bank of elevators serving multiple uses? Just because your smartphone tells you which elevator to take doesn't make this fundamentally different than if one were to just walk in and take the first available elevator to whatever floor by pushing the button to the floor they want, whether residential or office.

Neat idea. I never considered how important an elevator is or how much space they take up. Vertically stacked elevators that have a defined non-overlapping floor range might be a good idea in some cases. I don't even know if they already do that!

[@JasonJrake]

Yes, really tall buildings usually do that. For safety and redundancy. That way if an elevator is out for maintenance in a 30 story building, you only lose fifteen floors of mobility at a time. It’s also easier to inspect, maintain, and build something that travels 10-20 stories than something that must be reliable to travel 50 at a time. Dividing the trip over multiple cars can also save energy depending on traffic flows. It’s also done for high privacy/security suites. Most elevators go 60-90% to the top, and then there’s a separate elevator(s) to go to higher floors because a defense contractor or a rich guy rents everything from there up. Or the CEO wants his privacy. That kind of thing. There are other reasons to divide them up, but these are the basic ones.

[@simontist]

@@JasonJrake They don't even need to be strictly limited to certain floors, just to have limits that keep them a safe distance apart. Depends on how sophisticated the (safety-rated) control system is.

[@capitalinventor4823]

I worked in a building with vertically stacked (double decker) elevators and I hated them. In this building there were two lobbies on the ground "floor". The lower one for odd number floors and the upper one if you were going to an even numbered floor. People came in from the outside from the street at the upper ground level so if you worked on an odd numbered floor you always had to go down a floor to go to work. If you came in from the parking you were on the lower ground level. Starting from the first level of offices and up when you called an elevator you could get either the top or bottom of an elevator carriage. However, if you wanted to go to the top floor, which I did often as I had to catch the separate elevator to the data centre on the roof there, from any other floor it meant you had to be on the top compartment. Sometimes this required calling an elevator multiple times as the system chose the bottom compartment to stop, inconveniencing any people already on it for a potentially wasted stop (there may have been people upstairs wanting to get on the elevator). Then when leaving the building you were brought to either the upper or lower ground floors, depending on whether you got on the upper or lower compartment. Taking the stairs would have been wonderful but because of security they weren't an option from the ground floor. Stairs are only thought of as a means of escape in emergencies so they are placed on the outside, at least here. If they placed stairwells on either side of the elevator banks then stairs would become an option for people in secure buildings. People would pass security and then have the option to take the elevator or stairs. While not great for people on top floors, those on the lower floors might appreciate the option. I would have.

[@TheBigStick76]

You missed the fact that residential units need operable windows (at least in the US), office buildings do not. If the building is planned with operable windows to begin with it would work, but usually that is cost prohibitive.

Downtown St. Louis has at least two high rise buildings that’ve been completely vacant in recent years… the former AT&T building which is almost as tall as the Arch & One Metropolitan Square, and the century old Railway Exchange Building; better known for decades as the old “Famous” store building (was Macy’s for more than a few years but they completely closed 10 years ago). The latter has not only been completely vacant for 10 years, but currently has immediately noticeable exterior vandalism on the roof. There have been plans for increasingly awhile to convert said buildings to residential & maybe hotels, but obviously it’s all about price & willpower to basically rebuild the entire insides of said 275-587 foot (1.2-1.4 million square feet) buildings.

Of all the problems that have to be solved with flexible usage, then the addition of programmable elevators seems to me to be one of the simpler ones. The most difficult is surely going to be about the other infrastructure services that need to be sorted out. Of those, I would pick out something as basic as plumbing as the most challenging. Any office is going to have a need for perhaps 2-4 locations on each floor where toilets are required. Perhaps some kitchenette type facilities. For this, then all the plumbing can be concentrated, vertically, in just a very few locations. However, when it comes to apartments, then they are each going to require a bathroom or two, as well as a kitchen. Maybe a dozen apartments a floor, and then the plumbing infrastructure is going to be well dispersed, and you can't easily have vertical runs as there may be an office beneath. Waste tends to have minimum fall requirements. Even more demanding will be catering for hotel type accommodation, when each room will required its own plumbing infrastructure, and again traditional, vertically aligned services are going to be problematic. There are other services which have to be dealt with, like electricity, telecoms, security and ventilation, some rather simpler than others. Maybe the most intractable will be the lack of access to natural light at the core. Many countries have rules about what sort of habitable rooms must have access to natural light. That will limit the way in which buildings with large areas per floor can be used. It may be that kitchens and bathrooms without natural light are not a problem, but it will be for bedrooms and other living space in apartments. I'm not sure what the rules are for hotel rooms; there are cruise ships without natural light for inner cabins, but is that allowed for hotel rooms? Now a lot of this could be designed in, on a new building, although it will involve compromises. For an older building, much more problematical. Not to say that something can't be done, but it is not going to be easy.

[@patricklewis7636]

This is an awesome example of thoughtful design from its inception. I’d be interested to see if this elevator solution can be retrofitted to revitalize an existing tower though.

They need to program it so that at certain times of day, when people are going to and coming from work, the elevators switch to serve only certain floors. If you have 40 stories, and 4 elevators, there should be a display screen that shows each elevator is now servicing only 10 floors. This way you aren't going all over the tower for all floors on each elevator, possibly stopping at 20+ floors as it goes up and down. You could even adjust it so that floors with more people that are busy at certain times get more elevators and floors that have fewer people with less traffic at that time get assigned less priority.
