a new age
because the solar age is an age without
chimney and without exhaust and yesterday
that makes you courage
47 states in Morocco at the
Climate Conference decided to 100
percent on renewable energy
put
I only see one problem that’s it
problem the time so it’s a fight
with time we will be there on time
get to a world without
Chimney and exhaust there I am
not so sure because there are many
slow down
the brakes include the
bundesrepublik
they have certainly heard that
Climate concept from the Minister of the Environment
and there are a lot of things again
deleted because you just the old one
industry wants to protect and you
see here that we are actually 100%
sun wind biomass water power life
but we can have 70 percent
energy imports we import coal
import gas we import
of course, atomic energy and you too
see here in this cake where the
main area is therefore building area
is involved with 40 percent
Energy consumption of traffic at 31
percent the industry at 28 and us
see that we turn in all areas
The hardest thing we can do here
with the traffic but also with the
building was
It’s going very slowly
they also see most of them
space heat via heat actually
It hardly gets talked about over the stream
spoken and in the stream we are
actually we are progressing very well
have over 30 percent now
renewable electricity in the network, however
in Baden Württemberg seat window
exception mainly still nuclear power
and kohlestrom and I do not know how
the country the way brings the bathing
Of course, Württemberg imported a lot
much more energy especially if the
nuclear power plants are shut down
yes, I’ll tell you a little one now
personal story about
Sustainability social architecture, then
When I started in 1969 I had many
It is not a social architect
solar architect but social
architects we have many
projects made kindergarten
handicapped youth center
school here in villingen or here in
Freiburg von Halle or in Emmendingen
old residence this was actually
the topic we mainly
have worked and so it always went
therefore actually in the
contribute society and where can
we help problems for the
to solve society
So in the 70s have anja
fought against the nuclear power plant in
Vienna was successful that was the first
nuclear power plant what to prevent what
could by the population here and
So there was a lot of it
develops energy saving models
solar houses etc
and 19 1986 was here in freiburg the
horticultural show as a big one
event
and there I urged that
you
the new energies also of the population
near and brings the city and the
Landesgartenschau has it back then
rejected exactly but we do not do it
if you want to do it we will give you
a lot like that and then I have
three such pavilions created on
own bill with sponsors together
that they see here even then the
integrated solar cells and these cells
hand our batteries charged here
for normal electric vehicles i have
25 vehicles purchased from england and
but a lot of muscle power came as well
I had solar mobile and myself
built even on the
Landesgartenschau we had one here
gazebo we had a workshop and
a service station the service station
was there because we had a course
created and there you could the vehicles
also try muscle strength
So not only the normal vehicles
bike but many other ways and
Even electromobiles could one at that time
I also succeeded in trying it out
because I was at the
was tour de sol should have made with
there were six days running in switzerland
actually with his mobile and mine
is it then this succeeded the start of
first world championship in solar car
drive to freiburg to pick up and on
this area here was the time
Country
Of course I had the illusion
adding much with much joy fun that
but can bring the population close
It took a very long time
Actually, today continues today
that by light vehicles
bicycles technique the plane
Electric is best
of course with
regenerative energies 987 I am then
with the slightly modified vehicle
become world champion
that was around in arosa last so the
last stage la rosa pretty steep
but he has a bit of luck too
same year I have a vehicle
built and drove through australia
also on your own account with few
I have to say that sponsors have money
not quite enough but I have
I had reinsurance here
a flat was used to the table
At that time I sold politics around the
to finance if not enough
money comes in but I have in purchase
and I have that too
I do not want it
do without
It has always been a challenge
you still see
this challenge makes courage for
a new project that is the vehicle
in the wind tunnel so I’m already
sponsored so with advice and did
and the wind tunnel of in wolfsburg the
is on the judgment
So that was the reopening of the
for the first time continuously
asphalted from darwin to adelaide
So over 3000 kilometers but around there
to come one must only times to
I need only 4000 kilometers
by land and of course with the 747
then bring this vehicle over it
which was also a crazy experience
problems then you actually
had to solve at short notice and spontaneously
really incredible stories though
because the time was not enough
the first plus energy houses and me
has to say so that’s it now
is my house and experiment house what
I have put into operation in 1994
complete wooden house so we have
just trying to do everything
you can look into the future
what can you do about it?
very ecological and future-oriented
to be
So you see a very small plot
nine square feet on it
This is the house that stands
others is nature again
returned and alois ockl that is
the foundation and from there is actually
everything made of wood and it was one that has it
never been given it has not
the technology was given for that
then I just developed so much
Trust the specialists that we
the trick you see is that
Roose the wooden tube the whole
house trek 11 10 minute wood for
Wood
there was no glue yet there was none
lay connections all had to
to be developed solar energy
above a biaxially tracked
solar generator down the house gets up
a pivot bearing that can be
turn the sun and bring naturally
then because the house is open on one side
It is seen here panorama glazing
It can be quite closed in the back
optimally catch the sun and wear it
also the solar panels as
parapets at the heat of the sun
generate and put into memory
above
that makes
yes, I would not have been after
i would have driven that australia
house of the heliotrope not trusted that
is also a brand new one
challenge and also afterwards
not the solar settlement so that was
actually a very important experience
because it was always the money was not
So there was no money for that
there and we had the property
finally buy solar settlement then
Incidentally, everyone here too is realizing this
Houses prefabricated as wood in one
day to set up a house
the houses are all different
are different size
have modular principle and back then it was
of course, also a lot of prejudices
everything is too expensive so was also
in the Baden newspaper was whole
difficult then afterwards the houses
to sell because just said it was
is too expensive and many things go too
not so we have that was before the
renewable energy law we had to
the costs include in the house the
solar technology that was still at that time
five times as expensive as today is one
the house did not count until 2000 as the
Renewable Energy Law came and she
I have expected and have
seen that actually turns
itself now so the technique can be
buy and you can even a bit
So you can earn money with it
so I was able to the houses too
sell without the solar system and the
solar system helped that yet
finance house in the background
put the wooden ship and are on it
again plus energy homes are like that
all plus energy houses 59 plus energy
houses and food ship as a brake here
it is again from the merzhauser
street side from mainzer street brings
a lot of noise and that was the sound
usually so that you live behind it
can and all I saw here
the gray areas
was also an experiment that’s all
Vacuum vacuum insulation or else said
far too expensive forget it is not me
but I expected and saw here
we save space and win
Office space and have seen that worthwhile
So everything works together
I can not do it either
even closer to it
new examples for plus energy
Houses
that is about to be realized
smooth 21 apartments in a wooden house
Unfortunately, six-storey wooden house looks
the wood here from the outside not because
it has to be protected wood it is
a group of generations made up of small ones
Apartment and which are also enlarged
So in Berlin-Kreuzberg one can
young cooperative that dare so
to realize a huge project with
the highest social and highest
ecological claims
the project almost went awry
Although they had a commitment from the bank
but now has the
chairman of the bank that now
the lead has with the
Finance told me that
Banks have speculated that it
goes wrong that they are the property
be able to exploit otherwise
So it is now realized that was
one and a half years of construction stop but it is running
Now this is the project Kids started in
Kreuzberg a new project in
schallstadt what we realize now
also a generation house we have that
now are called green
fantasy name but may arrive
Bit too as a plus energy house
Also above you will see the solar panels
the shadows here from the cells and
also in buses cells and us
also want to build it from wood and also
new living models here realize so
also with class of the flat so come
for me old wg or one
handicapped bg or whatever
everybody has their little one together
Apartment but in a larger apartment
where you can do more
Community spaces here a project something
in on the haid should be realized
This is actually a landmark sign
for solar energy
since you have long months the problem that
one was afraid that it blinds that
Drivers are blinded by the
solar cells here but we have
proved that we can do it
do not want that something there
reflected but we want the yes
Field energy also
a project probably not
is built
It was a competition for Phoenix Solar
all companies all solar companies in
Germany is doing pretty badly
and maybe even the last one goes
big company still in bankruptcy we
in europe because politics just
another is a short-sighted one and
Solar energy has slowed down you have it
underrated
we are glad that one counts
now over 30 percent solar and
Windstrom has and that makes the big
energy providers problems and wants
Protect and protect the coal
and just has the whole thing pretty
I still have the brakes
hope it forward again give it
there is always a manufacturer here
home is his solar his
gaining energy over solar that is
by the way, in the wood construction because we build
very much like wood because wood is one
renewable raw material is here
grows here in Germany or in
europe and it is important that wood
is used because that almost the
only possibility is to store co2
what we get out of the atmosphere
the trees have to grow
and gets out co2 from the
atmosphere and in the wood it can be
Solar initiatives are saved
We have realized the experiment here
just used space in addition to
use project study freeway has then
but also led to several
Projects have also realized here
the sc stadium was the first
football stadium something with solar cells
was occupied
[Music]
the idea was just solar initiative too
be and just on all appropriate
roofs to bring solar systems and that
was a big challenge
actually the hardest roof in
freiburg because it is here the south south
roof there is still roof and then this
half cone and then we have
here proposed golden solar modules
to do that would also be to that
theaters fit very well and were too
very confident that we will
Realized but it must be there too
say the time was not possible
was earlier cheaper then in between
now braked slowed down by
politics but i’m all over here
it goes on again
So because you prefer the cell up
the roof as shares in the cellar
yes that was a vision too
So the wooden supports are a big one
solar roof carry here at the same time
protect bridges that he otherwise rehabilitated
Must be for expensive money that is
in our opinion, we are also ahead
a cultural change
we have to change our lifestyle
reconsider and sufficiency is one
keyword what do we actually need
for real
So and grad bands and affordable
That’s what living is all about today
is discussed
it is not discussed that
we smaller dwellings need that
Cluster flats need to be here
thought about it that we less
energy efficiency because that’s money
But it costs us just here
Do not save for climate protection reasons
but also because then we run the
save energy costs
mobility concept here you can do that
save most
You have to be serious about that
I think and build with wood
already mentioned
I think I’m doing a bit now
short sufficiency living on the example
for refugees so we have for
Refugees wood modules developed a lot
small but then just with gallery
attractive very high spaces
can be prefabricated and completely
then be put in place
and then again
be taken away elsewhere
be set up yes you can then
connect
to larger units that’s mine
favorite subject actually free space for
encounters cars out of the city
It is much easier to change surfaces
use
how do you get that how do you get it?
the cars from the areas always where us
that was successful was confirmed to me
we live in paradise
the show the children say that since the
then adults in Grenzach
Settlement planned there is the route the
that’s the noise track we have then
along the highway one
soundproof wall made the but
at the same time a large solar area there
created and underneath can be parked
Be used for cars and bicycles etc and
All houses, of course, plus
energy homes directly at the swiss
limit here measures move
promote walking bikes e bikes
let lorry with bicycles
Pedelecs also the old handcart then
carsharing pitch sharing what we did
also practiced in the solar settlement
you can then objections pitches
or multi-use pool
electric vehicles and so on that is
it’s down there this is my vehicle car
I have not had one for years
this is my vehicle and im
connection with the train and
public transport is it
actually the new ones
Transportation is the belly
possibilities to have fun
to have a healthy movement
with loads pedelecs or just now
These vehicles are no longer a vision
but the first ones are already driving
strasbourg / kehl karlsruhe in switzerland
Here is this vehicle
Self-driving vehicles are needed
no steering wheel anymore
as twelve people can have a rising
get in quite comfortably
you can take many people with you
driveway so completely new
I can still finish plus
energy homes plus energy settlements
plus energy cities countries new
So intelligent mobility is not
just the car the car engine
replace with an electric motor
if at least then must be at least
renewable energies
but it is actually better
intelligent mobility a mobility
not the city clogged and broken
makes but just again free space
offers and affordable housing yes my
favorite book will contribute to the solution
is no longer part of the problem
thank you very much
[Applause]
