do we go to the jury we exercise will heat up the screen opens up to start selecting
00:00:12
i you commit this it meeting got the bergen sweet in in december we have minus fifteen
00:00:16
degrees the screen shots down there stands up to keep us warm and safe and and whatever
00:00:21
uh as some of you may be heard this morning that i'd make it human being uh in the last
00:00:26
ten degrees outside will die very quickly we don't survive
00:00:33
so um uh starting with that and then we build buildings
00:00:38
and going around all the whole round the world i see fixed values
00:00:42
for compliance and we build buildings
00:00:45
with um non static or static skins
00:00:51
uh just to comply with building recollection we
00:00:54
we don't get the building enough possibility to brief
00:00:59
and interact um for the well being of the people but
00:01:02
also depending on what's happening on the outside during the year
00:01:06
i mean in singapore in colour or there is more or less thirty five degrees all year
00:01:11
but where i live i have minus twenty two to a a plus thirty five over here
00:01:20
and uh i'm just to give you a bit of a feeling what we talk
00:01:24
about here like love this because i hate channel button megawatts and everything because the
00:01:29
brain cannot manage all that the zeroes in those numbers but i deal a sustainability
00:01:34
consultant that i work with the new delhi he's at anders i make the math
00:01:39
one square meter of the saudi new delhi during one year is exposed to the same amount of energy
00:01:45
that you need a home to make forty thousand cups of coffee or boring thirty thousand x.
00:01:51
so when instead of talking ted uh what's i think you can imagine yourself a whole with thirty thousand eggs for breakfast
00:01:58
and now we allow very often a lot of that energy into the buildings and now we use
00:02:02
mechanical devices to push it back out again so we can survive is kind of backwards isn't it
00:02:10
so what i'm advocating here today ace dynamic automated smart
00:02:16
behaving source eighteen combined weight that's more choice on dos
00:02:23
that's a very important particularly when we are talking interior shading applications particularly get
00:02:31
so it and and this is what we see all around the
00:02:34
well this happened to be victoria station in london in july when i
00:02:37
was there doing seminars for architects during the week in in long that this year i i did two weeks in u. k. every year
00:02:44
and it's like your laundry on a string in a garden or something you know architects
00:02:49
gold it's crazy they hate this but why is this and i will touch on that
00:02:55
but it's a question out should all savings be manual or automated so let's take a lot
00:03:03
get very tense you you guys might address probably means behind a a
00:03:21
oh okay you're you're you're gonna have to pay an example
00:03:32
all right fine i can see what's happening very arid open
00:03:39
so i you're laughing because you recognise something you know that right i say this is the level of intelligence
00:03:45
you get when you put money all shades in in uh i work with commercial buildings but a home as well
00:03:51
so um let's take it also lock it so happened i was in any you
00:03:55
project a couple of years ago when came across a professor but napoleon is what's that
00:04:01
looking at because switzerland is one of the number
00:04:04
one countries that really using it accepting a solar
00:04:08
shading in their buildings you will see that if you walk around we go by train look up
00:04:14
they were studying how do intelligent people in the
00:04:17
university campus utilise their a manual shading during one year
00:04:24
the only study i come across i i've come across so far for the past
00:04:27
six years and i've been looking tells you if you have something to share with me
00:04:32
half a million pictures during one here monday to friday every
00:04:35
hour and the result was less than two movements per week
00:04:41
i dress a tilt or up or down so this means if you think about it that sometimes actually we are
00:04:48
losing benefits it's negative for the building that money was shaking
00:04:53
that's particularly cold winter nights but i come back to that
00:04:57
that we compare it to to to want to george street in in
00:05:00
sydney where we've been involved in in a planning this this goes back a
00:05:05
number of years and you can find it in this city journal for example
00:05:09
from march uh there is a great story on it or or an internet
00:05:14
it's a unique building would bulb lights it's it's they had a massive budgets
00:05:18
but anyway five hundred and fifty two thousand movements in the year
00:05:24
told us that forty to fifty clicks on the slack to cut off the sun
00:05:28
angle during the day to maintain the indoor
00:05:32
livelihood for the people here was was required
00:05:37
and that's all right cool and what we did here was we we help to analysts
00:05:42
the building on a window by window bases during the whole year so we know exactly
00:05:48
we computerised where the sun is positions so when there was a
00:05:51
trigger point we know exactly what windows to move or or not
00:05:55
always to maximise the view to the outside et cetera this facade was
00:06:00
also interesting enough a combined with low wiring draws in the outer skin
00:06:04
which is more clear than than than a visually than than the standard clear glazing
00:06:10
that is like lonely on the inside of the stubble skin just to reach the you value requirements of australia
00:06:17
but it means if there is another building coming up in two years
00:06:20
you can't really run the analysis and you have a different channel patent
00:06:26
uh bowlers here was that arab said they installed fifty percent less
00:06:30
steel beams in that building you so it's not a small house
00:06:34
a massive cost saving there's another challenge that i would claim
00:06:40
that budget to subset dies the investment cost on the shady
00:06:45
but this is rarely done and this is what i hope to inspire somebody to
00:06:49
start thinking about think holistic lee around the
00:06:52
east he functionalities in buildings that's really important
00:07:37
oh yeah particularly note the last part personal
00:07:42
interaction that's extremely important i mean energies all fine
00:07:47
but i mean and and uh and an l. c. a. the analysis on a building let's say seventy five years
00:07:52
that sector et cetera it's it's established that the cost of energy is probably less than half the sense of that
00:07:59
cost generation of that building last cost uh people reaches up to eighty percent
00:08:05
so um that people being happy healthy and productive it's extremely important
00:08:11
but yet again it has been that the parts that the budget for the people that's the tenets
00:08:16
the budget of the building that's the developer and the investor but i see
00:08:21
market forces now joining this because there was the dream on from the tenants alright
00:08:26
putting new the malls on the developers gave me green
00:08:30
buildings give me healthy buildings otherwise i'd move somewhere else
00:08:34
so that's a very positive development but we need to do more
00:08:38
uh according to gas for your up the uh have an estimation
00:08:42
i think two three years ago eighty six percent of all the
00:08:45
windows we got in europe today as single or double cheered like racing
00:08:51
so there is a massive refurbishment neat that they advocate for for better dos where i would advocate
00:08:58
today briefly that you can do a lot in the first measurement with dynamic shady i will show you
00:09:06
so what i've done here is i just take in a single tear casing the blue is the g. total
00:09:11
and and the the like transmit then is that the orange so that's the dos that i
00:09:15
add the well performing fabric on the inside and i bring the values down to this level
00:09:21
you see here zero point one to keep that one in mind when we go here doubles here j. c. we go down now
00:09:28
we look at more modern glass and i take the example my
00:09:31
colleague here from single buying a it's a seventy thirty three gas
00:09:36
uh with shaving i would take it also look at that that story maybe you can't read it
00:09:43
but the beauty of this combination of of modern up to
00:09:46
date combination is that dos would manage in this situation most
00:09:51
of the time during the day in the year but there
00:09:54
will be peaks all problems when the sun is really hitting us
00:09:59
and then we add the solar shading as a function during those two hours
00:10:03
or so and then when the sun is moving around the corner we remove it
00:10:07
so we minimise the solar shaking movements in the window which i know to be
00:10:12
honest could be badly managed a a big
00:10:15
factor of dissatisfaction so i really enjoyed this
00:10:21
it's a perfect want a quick reminder um i've met sustainability consultants in many countries around
00:10:28
the well the past five years so i can tell you there is a total ignorance around
00:10:32
the potential you value improvements used by a bit obtained by by using interior so
00:10:38
much it so i just gave you some numbers to trigger you a little bit
00:10:43
you add zola shading to single tear you add solar shading to
00:10:46
double clear for the seventy thirty three you see significant numbers here
00:10:53
the product is already there it's cold outside we go to bed at eleven o'clock
00:10:58
whatever we leave the office at maybe six in the afternoon it's it's a winter
00:11:03
no light why don't we pulled the blinds down until the next morning and obtain these it's it's free it's
00:11:09
there it's just one more click in the algorithm to make it at the solutions for this are already existing
00:11:19
so out challenges in front of us
00:11:22
i say as a solar shading i would get a a major reese you
00:11:26
process who take specification responsibility through the
00:11:29
process from i. d. design to execution
00:11:34
documentation i'm working a a lot in it we have actually a networking sweden now
00:11:39
we are writing a book on the topic to give some guidelines and ideas in english we hope it will be ready to
00:11:45
to next year or something like that to be a openly shared
00:11:49
uh with uh any audience but it's it's a major s. u.
00:11:54
what happens is that dos is very often because it's part of the first thought it specified very very
00:12:01
shading and we end up here at the very end uh but i
00:12:06
say we should be specified to get their based on very quickly what i
00:12:10
just showed you on the few slides before i we should follow which
00:12:13
are the through the process and be understood why this selection has been made
00:12:20
'cause i've been intel this meeting where the guy starts the meeting is say hey guys
00:12:24
we need to go x. points lead or x. points brie i'm now given the cheapest points
00:12:30
ah solar shading to point x. budget bicycle parking double the
00:12:35
size same points a tenth of the budget we go bicycle parking
00:12:42
and it's a budget i would quickly say now because i do more slides
00:12:47
the best you know whatever it is always the one we don't need and that's where i come from
00:12:53
in terms of production provision et cetera
00:12:56
we work a lot in silos corporation this is the key we
00:13:01
don't need the lawn masks to come up with a new invention
00:13:04
we just need to start talking to each other in early stages key players
00:13:09
and this is why today you see some combine some free and i quote together
00:13:13
on stage because we would like to demonstrate what we do uh to push this as a positive development
00:13:21
thank you
