you know that today in the world proof of the population of the world actually live cities so cities are very reporting to us but cities also give us a lot of challenges especially the architect plans because most of them face a growing population not only is the population growing but it's aging and people continue to have aspirations for a better quality of life and as the
city's gruel we would have to develop more infrastructure and services for the and if to make sure that the services work and with climate change we have to encourage people to use less energy so that we reduce carbon emissions so cities six solutions to address these challenges how do we deal with them well many cities are starting to adopt smart technology to improve our environment and
our daily living but what is smart technology everybody talks about being smart well it's a very simple form it is really hard to sing infocomm technology the internet of things and Hama sing the power of deter getting insights into data to actually develop smart applications that make the day to day living for us double it has been projected that by twenty twenty five we will have
at least eighty eight smart cities in the world what about Singapore well the prime minister has said that our vision is for Singapore to be a smart nation a nationwide people leaf meaningful and fulfilling lives and Ablett seamlessly by technology offering exciting opportunities for all no dates really about people and not about just the technology but now we are ready to be smart well I think
we're pretty much on the journey get quite why it up ninety percent of homes have brought bed and we're gonna bring fiber to every hole and simple has one of the highest smartphone penetration rate in the world at about eighty five percent so we're on the journey but what is a smart nation I'd just like to illustrate with an example of a hasty become a public
housing town close to my heart and I quite the hot legs ways of the highlands because the house is eighty three pop percent of the population and many of you and I live it hits the beach towns it about a million flats so what is so smart town this map don't really functions like the human body we have all the buildings in then the activities take
place like the muscles in our body we have greenery and pots like our lungs to help diplomacy a for us give us a box a brief and we have all the votes just like the veins and arteries in our bodies that move to traffic the people of the goods and nobody has the five senses and the census Santa Breeden a it senses what happens in the
environment and tells a breed how to get the body to adapt whether he's hot or at school so if you ever censor Leah onto our town it collects data and insights from this data can help the town to could do you know to learn and to adapt from this we can develop smart applications for D. to D. living as an architect Blaina actually I planned and
built many of the towns that you live it and I would very much like to build a small town this livable efficient sustainable and safe for you we are going to look at smut in four areas smart planning smart environment smart estate services and smile living what is smart planning as an architect planner I love this pop because it helps me to design a better living
environment for you not what a smart planning basically the first thing I do is to collect all the data about how the buildings of role it's pops and I put into the computer and I'll also collect a lot of information about energy use at least example and with this information I can develop a tree died mention the map of Singapore in the computer now what do
I do with this information well I can do a lot I can do a computer model that simulates the wind flow strode town in the tropics we love the bin what are in Chicago not even look at this diagram does the yellow and orange means that the wind throws up pretty good the one's in blue means is a little bit and it doesn't move so much
so what we did the first couple of fungal eco town this was the pattern of the blood flow and then we adjusted the buildings remove the pox around then you find that the wind flows improve you see Malta orange and red colors which means you get a cooler the betta equity through the tunnel computer simulations can do many things you can do it at a top
level all we can do it at the precinct level and we can even do it at building level so well comfortable would not show is a town they beefed up precinct with just designed which I've just launch for sale I don't know how many of you apply a full flat that of but I highly recommend it it's a great place to live alright now it is
I similarly when we first did the design we looked at the windows for the town and like at a top level we also made adjustments to the design I move things around cut holes in the buildings and you can see that Winfield seven prove equally in the neighborhood center alright we want to though a lot of natural ventilation so that we can minimize the use of
air conditioning no computer simulations can also help you in many ways you can't do a shadow analysis of the town here you see the shadows moving from morning till night why is it important well it helps the architect on the planet to decide where to put the puck and outdoor dining areas all the outdoor clauses playgrounds and my child has sent a letter to put them
in the sheet so that the children can be out the whole day the computer can also tell you so let you regions in the town how much sun actually falls on the surfaces the town and on the buildings and why is this useful well it helps me to dislike for example with this moderate sunshine I'm going to put the roof gardens there and when there's a
lot of sunshine that's where I put my solar panels we talked about so the panels and it is very effective all this information helps the architect designed the town not only aesthetically but also to ensure that it is functional so this is a waterfront out quite nice you can stop applying for it now we can Leo senses to the town alright can Emilio census that tells
you about the humidity the heat the wind flows and all this data that could lead can go back into the computer systems to validate the assumptions and make even more accurate but more importantly can be used in many ways for example in my neighborhood said to have these huge fans not hope that these fans can be triggered when I collect data on now a win and
monitor the humidity and heat they would be triggered when he hits a certain threshold level but that is subprefecture up old towns so welcome to you plug to Rome and all the state what we did a couple years ago is to try to introduce a lot of suspicion ability in the fetus into this estate to making greener which means most likely in most solar panels for
clean energy a we put in reports of how the sticks systems Pat might make it even smarter so they do have more effective so for example we have put a lot of solar panels on hundreds of buildings and he should be blocks you may not see because you didn't live up to the roof now we put a census to all the solar panels and we tracked
the energy that's collected and we know immediately when a panel is not working because it would not be collecting energy and we can fix it but do you know that such data collected can do many things it can even tell you the weather conditions for example if many was solar panels on not a collecting a lot of energy it might mean that over that town it
is cloudy all it is actually Rini so is a prop proxy two of the meteorological station and not a service that we see a lot in town or estate service web very familiar with is the lighting a long corridor now how many of you walked into a toilet and it suddenly switches on and you get a shot from not to like it right well slept census
allow a person to walk along the corridor you can't even predict where ya going and then the lighting level picks up and when you have posited the lighting level dims again safe energy and the data collected is useful because eve along that corridor after eleven PM every night very few people actually walk that system is smart enough to lead the patent if you do use of
the brightness of the light and safe energy another app Estes service well all very familiar with is the lift we have twenty four thousand lives in haste be towns and we monitor it everyday but when you're sleeping at night you may not know this but we morph the lives sleeping alright this no ghost remove it the reason being that wet testing it to make sure it
works when you take the lift the next day right now we of course were the live Greeks now we would be %HESITATION we go get a signal and we have to go fix but you know it with the new census maybe you can even monitored the vibration and heat generation of from the lift and you can't even predict a potential felid before it even happens so
that we can go and fix office so that's wonderful right be but pretty now this is a map of Singapore and you look closely you think a lot ends running around now this loop movements actually this is real time shows you where all the taxis are moving around in Singapore but why do we want to collect such data is great data for possible penance because by
looking at this data the tosspot Penna knows the real condition and with the congestion now we can push this data up to you to oil spot films I'm sure all of you has smartphones alright and you know straight away which brought to avoid ugly home from and to you later to wherever you come from you know it you'll have it easy thing cadre of time you
go up the bus you tap the easy leg caught no good data is very useful because when we collect that data we can tell you which bus is crowded so when you're waiting for your bus on a handful you would be able to find out that this bus that's coming is going to crawl that so you might want to take another bus change a route alright
so such information and data is very useful now next I talked about smut living alright closer to home by twenty thirty we will double the people who are over sixty five years old from four hundred fifty thousand to about nine hundred thousand in nineteen seventy about thirteen people support one person was over sixty five years old by twenty thirty their only tool vests supporting a parent
who's over sixty five years old and would do all income families it means that many of us may not be whole and our parents are left alone well need to a my residence this is Doris and a mom is seventy eight years old and Doris has to go to work alright she has to of key to to the family and she takes care for mom but
she is always what it because her mom once had a fall at home so is very worried when she's at work so what we did was we pilot tested a system call seamounts smart elderly monitoring alert system in health home so what we did was we went into a whole minute we fix a little sensor a couple senses throughout the whole and what this since it
does is it monitors the movements of her mom but they don't just monitor it loves her Patton over a few weeks example the kind a few weeks up now if this pattern is broken he becomes very irregular all dust no movement at home what happens is that a signal is automatically sent to dollars's headphones when she's at work and Dorestad quickly call home and check if
a mom is alright or to let the neighbors to knock on the doll and I think this gives stories a lot of peace of mind so with an aging population such smart solutions are actually very useful another application study health when your work and mom has no one to send her to the hospital she may not need to go to the hospital she can be home
and to have physiotherapy within the us watching her and treating her to make sure that doing it correctly can do this in the comfort of the living room and in fact her heart beat can you monitor and a blood pressure can be monitored and so it is very convenient but also because he needs to go to the hospital the nurse would tell her that you need
to come into the hospital so I think another very useful application is the home energy management system like everyone is quite familiar with this it tells you how much energy all applies since I using apple but the smart solutions can even lead to when he'd reach a certain you sick you can even switch off your devices when you're not at home and do you know that
you can't even do this when you go to bed at night and you turn on the air conditioner or not if you like to be very cool I don't know what temperature eighteen twenty twenty one alright but he uses a lot of energy so what happens is after yes very quietly the device is going to raise the temperature of your expedition and you won't even know
it and therefore you save energy so I think all these applications can make a daily living better but of course we'll have to select the right technology we have to make it very friendly and frankly the C. must system my short you actually a Darcis mum I found it very easy to use and of course we have to make sure that we strengthen cybersecurity because by
