Hello and welcome to the new "WAGO on Tour" video. I'm Mirko, and next to me is Julia, and today we're in front of the centerpiece of our digital everyday life. What we're talking about is a data center, just like the one behind us. We're in front of one of the 45 data centers of this data center operator in Europe and one of two in the German capital. And who would that be Julia? Right, we are here at NTT DATA and NTT DATA operates data centers, among other things. And as you said, data centers are at the heart of our everyday digital life. Why? We need data centers because the entire amount of data we produce every day has to be stored and managed somewhere. And that's what data centers are for. As the amount of data continues to grow, we need more and more of it. The data center has a very high energy requirements and therefore we have a direct high-voltage connection and a substation on site. The IT capacity per building here is twelve megawatts and we have here an area of almost 10,000 square meters, approximately one hectare. And this area is even even being extended. You already said it: The area is being extended. That means we have a construction site here, we'll have a look at that too. But before we do that, let's take a look behind the scenes of exciting Projects such as waste heat utilization and energy optimization through AI. I'd say let's get going, shall we? Yes, let's go. Wow, that looks really big here. Yes, full. I would suggest we split up. You on the left, me on the right? Yes, with pleasure. I am already meeting Steffen, who in this project a plays a central role. Hi Steffen, nice to meet you. Hello Mirko! I would say, introduce yourself and your and your tasks first. With pleasure! My name is Steffen Benson. I am responsible for the measuring, control and regulation systems Building management systems in the EMEA region. We are standing here in such a big, white, empty room. What is this all about? This is a typical data hall that we make available. Later various customers with their racks where, of course, we provide the cooling, the Provide electricity, but also various Carrear. What would you say are the main the main goals from your point of view and Challenges with this project or projects? So I say, of course it is important that you can also use our WAGO controller always has a safe environment, the infrastructure a safe voltage source and of course also protects these controllers from external influences of any can protect species. Okay, very interesting! What other projects are currently on the agenda here? Our current projects include the local heat utilization of our waste heat. This means that the heat we produce here we produce here, we try to Community to provide for houses or other facilities. Of course, we also have the artificial intelligence project. We are always striving to think innovatively think and improve our refrigeration as efficiently as possible. That is why we will use AI for the future. And, of course, we will also be building build a new data center next door. First of all, thanks for the insights! I always find it super interesting, how much planning and above all Technology in such projects work together in the background. The cooperation with WAGO has been running many years and before this Background we now meet Markus. He is WAGO's Senior Sales Project Manager for the Building division. Hello Markus! Hello Mirko! You have been accompanying the collaboration since 2005. What were the reasons that WAGO is used at NTT DATA? At that time, NTT DATA, to have an ETHERNET-based PLC which supports the Modbus® and SNMP bus protocols and additionally HTTP. At that time we could already fulfill all these requirements. Yes, very interesting! I have another question for Steffen. I would suggest we swap places the places, then I am a little closer here. Steffen, what were the two most important most important reasons that WAGO is virtually used? The modular, compact design was very important to us very important, but also the flexibility, that different input and output output cards as required. Yes, I think that sounds super exciting and above all a pretty strong partnership. I would say we should see what Julia is doing. Due to the intensive computing power and energy consumed by the servers and network devices, data centers generate data centers generate a considerable. Waste heat. And this heat is used here even used for other purposes. How exactly does this work? That's what Marvin is telling us now. Marvin is Senior Mechanical Engineer for the EMEA division at NTT DATA. Hi Marvin! Hi Julia! As you have already said we generate a lot of waste heat. We pick up this waste heat at the warmest point in our system. We are talking about 30 degrees, which we we get back from our systems in the IT areas. We take this heat at the minimum of 30 degrees, pass it through a heat exchanger and then set it to about 28 degrees our external partners. They then use this heat to heat office buildings office buildings, for process heat, but also for residential buildings. Typically, you then raise it again with a heat pump. How exactly the communication technical level with our partners there works, explains Steffen at the control cabinet. Great, thank you very much, I'll have a look I'll have a look there now. Steffen, you are going to explain to us how the communication on technical level works. You're very welcome! Here we have two WAGO controllers next to each other, which are connected via a communicate specific protocol. As a critical infrastructure, we must of course take responsibility for have that on both sides the data arrive securely and can also be sent. Therefore there are no problems with this no problems with this solution. This solution between the two controllers we have also regularly tested in penetration tests by independent IT companies. Yes, especially in the critical infrastructure cyber security must be must always be ensured. Yes, thank you for the insight and I would say that I now give out on the roof to Mirko. I am here directly on the roof of the NTT DATA building, right next to the refrigeration systems and meet Marvin, who gave me more will tell you about it. Hi, Marvin! Hi, Mirko! Can you tell me why cooling is is so important for data centers? That is quite simple. All the electrical energy that flows into the into the data center is generated by the IT systems are converted into waste heat and that's what we do up here with our Refrigeration system then switched off again, which is a significant cost factor in the operation of a data center. And how does NTT DATA counteract all this? We have been working for many years with a Swiss product, the Refrigeration manager up here that controls all systems automatically, which then helps with Efficiency in the refrigeration system. Okay, and are there further optimizations planned? We are currently setting up an AI on the refrigeration manager, which will then replace the previous manual optimization of our colleagues on site replaced by an AI and automatically optimized the whole thing. Okay, so when you talk about saving energy you can say how much Potential savings there approximately possible? Depending on the characteristics of the data center, whether large or small, we expect Savings of up to 35% of the electrical energy that we use here above for the refrigeration system. I think that sounds really exciting and I think it always shows, How smart technology can help how resources can be spared. I'd say I'll have another look at the the construction site again, which we have just discussed. Yes, Steffen, as you can hardly recognize us, we are now here on the construction site and a new one is being built here Data center building. Would you like to tell us tell us a bit more about it? With pleasure! We are here on the construction site and you can probably tell by the footprint, that this is about the same as the already existing buildings, except that the Connected load here is considerably higher. We are talking about 36 megawatts for the entire building on an IT area of 11,600 square meters. This building is due to go live in the third quarter 2028 and here, too, we will again use the modular design from WAGO. You have now mentioned the modular construction. Why is it so important for you? The modular design is very important for us important for us, because we have already have learned from the past. The data centers that we have had online since 2005 online since 2005, also have the WAGO controller in itself and we were able to simply replace them, i.e. simply just replace the PLC, nothing else on the change anything else on the cabinet and we could also continue to operate again without major modifications. Yes, mega! Many thanks for the exciting look into the future. I'd say I'll go and see where Mirko is again. Hi Julia, there you are again. Hi Mirko, I've just come directly from the construction site. I've even just been to the construction site. Did you know that the green areas there were taken into account when building the data center to allow native bird species to nest there? I didn't know that, but mega interesting that this is taken into account. What did you watch? I have learned more about an AI project. With the help of automation technology from WAGO and a AI controls the cooling of the server rooms, so that they are virtually days is perfectly adjusted. Did you see anything else anything else interesting? Yes, I actually got the waste heat utilization. A lot of heat is generated here and is also used for other purposes. That was also very exciting. And I generally think that background that there are more and more data centers will exist and efficient efficient use of resources is important, this is really a forward-looking project.
