Gut, After Noon, Ladies and Gentlemen. I'm sorry,
this talk will be in English,
because my German is till not solid enough,
but discussion than can be of course in German language.
Okay, so I'm then your hommada,
I come from Berlin University of the Arts, but also,
I'm also affiliated to einstein center digital future,
I am
Unior professor for digital education,
since last August
The environment of art University, like QDK, it's quite special.
So also, you will see for example,
such playful illustrations, created by students of visual communication,
which formed something good klasse klima.
It's like a student activist, group within the UDK,
and one student decided to support my doll,
quiff such illustrations, for example,
this one, is called to let the
mession sleep
One of the main, most important messages,
I have to transfer you that basically these days to main
dominating paradigm in digital education and you learning especially,
with mooks for example,
is that these services and these messions,
these devices are available practically all the times,
2047. It's basically,
day can as grandtate that to the digital stories is are
all the time available and as a professor at the Art University,
I try to propose,
maybe some other solutions
Okay. So, does it very know, we doesn't.
So let's do a legadias. Pop. I reen.
Or we're refresh, maybe. Ist komplett broken,
oh what, well. Okay. So, basically.
Given did I'm like professor of digital ucation, a question,
can be post, what is digital education?
Everybody speaks about it, public discourse is filled with discussions
about this, but in fact, if
you look into dictionaries, you will find out,
it's not precisely defined
Some people speak more about like computer science education.
Let's deech children how to program. Let's make clittle makers
. Let's deech gets how to make their owner artifacts.
That's one definition of digital ucation, the other is,
we used digital divisors, like beamers, whiteboards and so on.
In generic teaching or learning process. Somehow in what I do,
and the concept I develop, I tried to United this
to currence, education awave digital and education about digital.
And also involve for nature or enevarumental espects into into discussion.
So basically this are do main concepts,
I'm working with, human, computer and nature.
Because you cannot have digitalization, we folds a energy,
you cannot have digitalization and we fold all the supply chain,
which is generating digital devices, CPUs and so on.
So that's, what I'm doing, okay, saw of tricky.
So briefly, human is my plus digitalisation,
plus ecology, it's what I called Bildung or codigitale.
Alright, now let's define What is a digital school? Are ada,
I'm going to give you one concrete example,
of this building here, cold media and house,
UdK Media house, and nice building in Berlin Schöneberg,
what I also used the work before,
I've defined it my PAGDs as an IT-Administrator,
so I basically know all the devices.
And to have nice rufs, hope flyriar going to install some photovoltake panels, there.
And that is basically what you will find in a such a building.
Okay, I mean, you will find desktop computers, notebooks,
tablets, smartphones, you will find to fiber optic adapters,
you will find switches routers, hubs, stuff related to audio,
speakers emblifiers, you really find GPUs, Graphic Processing Units,
now TPUs are coming, so tensore processing Units for mission learning.
There's a planey of planey of devices, of course,
of course, veal and access points, yeah,
laspberry piece, internet of things devices,
different types of printers, freedy cutters, laser cutters,
I mean, freedy princess, CNC cutters and so on,
power supply and power management, applications specific integrated stircuits,
we also have our own service,
Robots will join the club soon that already some automats.
So there's a planet planet planet of digital devices.
Wir finden, such a building. And of course,
they all consume energy and many emang this devices,
there running 24-7. Even if they don't need to.
And there also run you ring some evacation,
when there's nobody in the building can saw on.
So, now, to another definition, carbon nutriality,
infect surprised, not men is students, know what this means.
So I reader bring this definition from Camproduktionary. Ich verpasse so ein Organisation-Event,
ein setaratisches Carbon-Notrial, es does things,
such just planting three is to reduce,
carbon the oxide by the same amount as it producit.
Produce is it. I like this definition,
because it's also speaking about events, so for example,
compos innovation, could maybe I'm to become carbon
no utrale in the future. So, it's not only
about persons or institutions. It's also about events.
And of course, it's not only about regucing the public
consumption in the end. It's more about circuled carbon sequestration,
so basically catching the carbon the oxide, out of the air,
basically only way how we can do wait to these days is fotosyntasis,
with trees and plans.
And fix think it again in wood or something like that.
So yes, that's basically carbonalitrality. You emit. Also
match as you can catch. Okay, operational costs.
I have show not a building and when I ask youdical gebäudereferat,
what is basically the builants,
we consume something like 140 one mega that others,
a year, just for electricity.
So for all those devices. And I proximately
more than one giga that others for heating
So he think is the main colbrate, so to say.
And if you were do the calculation, it's,
ja, sort of 800 602 towns of CEO to eat.
Of course, depends, word energy comes from in Berlin
, we all try now to have sustainable,
nice starts is of energy, but we know how Germany is,
it's a lot based not corble, still these days.
And if you would do like, if you use this nice
system at sonny places.com, to do estimation of how much,
photovoltaik energy, you could so Optane from with this two roofs,
we have, you could good something like 2016-2, negot hours.
So basically, we could put tentially cover,
the electricity need of the building, but we definitely cannot cover the heating related costs.
Yeah, so even with very good will and we've photovoltake energy,
we are still something like, we are still,
we still need something like, 800, 800, 900 to mega wat.
Mega wat hours. Yeah,
so that's just to sort of buddhist into a concrete and since the question of this talk,
bost by the title of this talk,
is CEO to nutriality and digital school, can we aligned?
I have to say, in this very moment is no,
because basically, das System ist aus der Ballance.
That's basically the current result, but now, I hope to make the toll clittle
bit more optimistic. And little bit explain you my concept,
what I'm doing with my students. So,
first as a already mentioned, there are many many devices
running in idel mode for a long time.
So if you Multiply, the amount of devices,
we have the amount of, how much powerdate consume, when there in
Idle mode and the amount of time and the time is
the most important faktor here and it's multiplication,
then basically you already get some amount of energy,
which is basically vasted. It wouldn't be wasted,
if we would use this messions to heats the building core example,
so there are like, yeah, there are like,
hex, how to use these access heat,
but of course,
we are not doing get.
And for the time being,
this is wasted
And my proposal is to reuse this waysted energy this waysted
power with something, which I call a rhythmic devices or services.
There's a short article about this in this synergy,
which you can find at a DN-Prends. And that article,
I still college, stereo contemporal or if it concerns,
just daily rhythms, circudian artifacts. But infact,
it's maybe more easy to just call this services and devices, rhythmic divices.
So basically this devices or services are defined as our devices, respect service,
with pre-build rhythms, idea ally bove software and hard very behind-sed devices,
all services, are designed, designed and optimized,
to be automatically turned on and off on a regular basis.
If you did depart from this paradigm,
that the mession should not drawn 24-7,
which did sleep as this mession should do here, as doing,
then you have to do engineering in a different way basically,
because so iPropose basically to do Engineering in Sucha Way,
which basically takes into account is rhythmic nature of also human existence,
we sleep students, during the year,
they have vacations and so on.
What we are doing, where implementing this in one particular artifact,
which are call digitale fible or digital prima.
And we are developing this with my students, it should
be for elementary school kids. And in this artifact,
it's this cribed, in this article in anfangs auf das Smartphone,
Torwarts and new digitaled ucation artifact. For example,
one property is that it wakes up at help us to after noon,
is there away libble for the child, child can do here or his homeworks.
For one our, and then device goes to sleep again, and wakes again next day. So,
it's started of a completely contradicting, what everybody else is doing,
yeah, because basically the main paradime is a really digitalisation,
yes, it's available all the time,
even it for a toclock in the morning,
let's help down only smartphone and do this,
but in my opinion,
it's maybe more human and also, maybe more helphy.
So, this is basically some something, which is all of the outdoor.
Of course, just as a prototype. This is the main combination of component,
we decided to use rasberry pie zero,
which is the most minimalist universal to link mession,
you can potentially imagine, with with the pie, that's this black component.
And that's very important one, because it's exactly this component,
which allows the artifact or device, to wake to turn off,
that's easy, you can all live start of the mission in sort of moment,
but to wake it up at in sort of time,
that's much more tricky.
And for this, we use this very nice component
And another special feature of this device is electronic in,
I'm going to get to this in few seconds.
Okay. And other property of potential digital education,
devices of the future, is that that should be
outtark or outtark, like energy outtark devices.
So again, it is basically defined here in this article,
we defined and energy outtark or simply outtark device as a
device able to produce,
energy,
necessary for its
own operation
Ja. Eine Frage, off course,
it's not a perpat to mobilit,
it's simply some device with Solarpanel or whatever, you can imagine.
Especially Solarpanels, I think are the way to go.
And another way to go is electronic ink or electronic paper,
it's do technology people or Amazon uses in kindle
or Talia in Tollino and so on.
And what is so magic about this technology,
is that it needs energy only to reflesh and change
the content?
5 minutes,
crite, super
And that's nice, because all the other time,
when you don't need to change the content,
it's just there displaying, what you want to display,
deaching potentially or giving information as a post-poster on the wall
would do or a book in a shelf for do.
And solving the role, displaying the content and doesn't consume any any power.
Which is of course in comparism to screens, which our every everywhere these days.
A cologically speaking comuch more sustainable. So was again,
I think this is something, which could be maybe implemented
in sustainable Universities, or like Campus of the Future,
on in much more bigger scale, dann it is now.
Okay. Now to this final point. You may point
out that is basically lächerlich, what I'm proposing,
like to save, few that's of energy, here,
like using goes very piece euro, instature as very pie,
or using e-in can stead of screen.
But in fact, maybe it is not so,
because we are in the education context.
We are creating happits here, we are teaching children
or students, how they should be have,
maybe during all life long
So, if you basically create medium or media,
which basically invited child to think in an ecological way,
then it can have much bigger consequencies,
it can sort of create and autokatalytical process,
which will allow you to save much much more in the long rand then,
then expected.
So in this sense,
so the medium itself is the message and ecological message and,
yeah, and can be useful.
Good. Since, I have still have maybe free minutes
or two. Now,
little bit something comore,
more radical
You targ buildings and compos. So of course,
threes instead of lawns, plans, plans, plans.
Fotovoltaiks, Panels, on our roofs. Discored bequiet use full,
if we want to have like mission learning centers in sellers and the one,
it's maybe really used full to think about using this heat to heat to the building.
Heat bumps, because he think of the men cold Brett.
This is very important technology,
using fotos intesses to catch in the carbon the oxide,
opt than energy and optane Biomasse, LG-Fotobayer, photobioreactors.
And this is really something maybe, which doesn't exist yet,
so basically Maybe painting buildings in a special way,
so they do the fotos interests.
But that's future. But yes, we can do it
. But how we can do it? I think,
we really need we are really need in my opinion.
And this is from my experience with addministration, but also from student with students.
We really need not only people who who consult,
we are there like in der Haltigkeit Büro,
that's create, there are our such offices in Universities.
But infact, stince to emergency is already here, and it's really emergency,
we need people with executive powers ideally in every University.
So people who can come to this faculit here to this
institute and say, do this or change this.
So I think this is really, very, very, very important,
to have such people and make student involved in this processes,
because they are the ones we live in this world,
which we are creating right now.
Thanks a lot for your attention. And here are few
links. Especially this one is important for those,
where interested in a cost related to production of digital devices.
So how much it basically costs to create a smartphone and and so on.
The others are my publications and my website.
