It was an eye opening trip, the sofa was VERY comfortable and the talk is very interesting, They taught us about how the power and electricity has come about since the past and how modern technology can help to improve our efficiency with powers. Learning on how to read electrical/water and gas meters will be helpful to check if they are billing you correctly and to prevent overbilling. They have taught us on how to save electricity such as turning off electrical appliances when not in use and get the 4 ticks to have optimal efficiency saving 😁 learning about eco cars and how 100% electric cars can help to save the environment together with smartplugs where you can control your appliances remotely which can help to save unnecessary electric being wasted, e.g phantom. It was a fun and meaninful trip that teaches us how to save electric and use energy wisely. Most importantly the service that SP EEC provides are, financial help to those needy families and providing the “Pay as you use” feature that tops up money into a chip where you insert into the meter outside your house . ]]> 2018-07-27 11:21:20 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271281141 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271519109 It was an eye opening trip, the sofa was comfortable and the talk was rather interesting.

From the talk I have learned a few points on energy conservation and the history and milestones of Singapore Power and how the energy industry is moving to in Singapore. 

There are more companies coming up to provide energy to suits the needs of different consumers with different rates. 

Some may have a fixed wd tariffs like SP power while other have a peak tariffs and off peak tariffs which can help consumer decide when to use more energy or what not. 

But still, SP power is still the sole ooerator if the electrical grid in Singapore and they help to bill and transfer electrical energy from various plants into the grid fow consumer to use directly. 

So in short, SP power is a business that help other companies collect charges and bill then to consumers. 

So yeap, it was rather interesting I think, and they also try help people save energy and entertain some funny customers that complain about their bills🤔 ]]> 2018-07-31 04:08:37 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271519109 sohjinwen_sjw https://padlet.com/ykgatnp/CEM18_OCL2/wish/271522036 The learning journey to ITE college centre was an enjoyable and an information one. At there we went to a class to have a PowerPoint presentation by mr tan. He went through on the initiatives the school has carried out as well as how the building was build. 

It was really interesting how the green walls was place on the west side as it receives the most sunlight. And how the toilets and lifts are position there so that they'll require less energy as if class rooms we're positioned there more electricity would be need to cool it down. It was really interesting how the planning of the building made it windy and allow more airflow. It was also really informational how there was natural lighting inside the office which allows sunlight to go into the office so that less electricity is used to light up the office. 

And how they had a bbq pit which has solar panels on top which is able to generate electricity for the bbq pit. And how there was evaporation pools that cools down the campus. As well as how the solar panel is place at a tilted angle so the rain will wash the dust off. Most of the building design I haven't seen in other buildings so it was really interesting. I learnt a lot on how careful planning on the infrastructure of the building can save energy. I hope to be able to embark on more learning journey like this. ]]> 2018-07-31 04:42:13 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271522036 ykgatnp https://padlet.com/ykgatnp/CEM18_OCL2/wish/271527698 ^{I went to ITE college central on 28th July. We went to ITE College central to learn about the different methods that they used in order to be sustainable. ITE College Central have numerous sustainable designs and have help saved a lot of electricity and water in the school.
 One such feature was the Tilting Facade design that the school have.
 The tilting Facade design, is a feature that help saves energy as the school was designed so that the service things, such as the lift and the stairs, are facing west so that they absorb the sun heat. This is essential as the areas which does not need cooling is facing the sun, so the classroom and offices which have air-con, do not face the sun, which means that the air-con do not have to use so much energy in order to cool the building down.}]]> 2018-07-31 06:12:21 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271527698 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271528729 We went to ITE College Central to learn about the architecture design and the benefits of it. The buildings design from arrangement to the orientation of the buildings were constructed with saving energy in mind. These could from the direction the building is facing.The sun rises from the east and thus the west side has the most direct sunlight therefore toilets and lifts are located at the west side of the building.  By doing so, Offices and classroom does not need to spend more energy keeping the room cool. 
The Green wall also face the east  and roofs are covered with grass which allows it to block more sunlight from heating up the building. Plants are efficient in keeping buildings cool.
There are also solar panels in ITE Central which can generate enough power in a day to power a house for a month. 
These green features in ITE Central constantly reminds us that energy is finite and that constant efforts are directed towards going green

As a company orking together for decades to provide the citizens of Singapore with energy to power the lights at home, the tv for us to enjoy and also our phones for us to communicate, it fills me up with joy knowing that they too seek to cut down energy and wastage and to educate the public on how to do so as well. Providing us useful information such as how to read the tick rating system on electronic appliances as well as the average power usage of our appliances at home. This allows me to moderate my usage and help my family cut down costs. Also, having been told that the energy market will open up im the coming months only goes to show the eagerness for the industry and the ministry to increase competition and promote innovation and growth in the industry, leading to a brighter and greener future.]]> 2018-07-31 06:28:17 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271528751 s10186792 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271551020 We went to ITE college central  for our off-campus learning.  We went to ITE central to learn about their different sustainable features. I was quite excited as I had never been in an ITE before. 

Our guide brought us to a classroom and gave a presentation on all the sustainable initiatives the school has. It was very interesting to see how the school could incorporate so many different features around the campus. We were then brought around the school to take a look at their rooftop shelter, green wall and more. 

This learning journey has opened my eyes on how schools can be built. As of now not many schools have the same green initiatives that the ITE college central has and they have to start to make the world a better place.

It allowed me to discover the importance of energy conservation and there was a guided tour which covers topics like, reading your bills, water meters and energy saving tips for household electrical appliances.
Learning about the possible consequences of electrical appliances will deter us from misusing it and teaches us to be extra careful whenever we use them.
Features that assists us when we use our electrical appliances is the tick rating system that is incorporated whenever users wish to purchase their electrical appliances. The more ticks that the appliance has, the more efficient the product is.
Singapore’s effort to create solutions across industries to ultimately create green and efficient urban spaces. Singapore has successfully exported urban solutions in areas like built environment and city management, energy, safety and water.

When i was told that we were going to ITE college central i was quite excited as i have never been to college central.

During our visit, we learn about how the design of the school helped the school get the BCA platinum award. The school design was so well planned that they put all the green walls, toilets,lifts and stairs  on the west facing side of the school. Since the west side of the school get the most direct sunlight.

They grow grass on the rooftop in order to reduce noise during rain and help cool down the rooftop. To add on to that, they have made evaporation pools which helps reduce the surrounding temperature of the rooftop and the campus itself.

They placed 740 solar panel on the roof of the building which can generate 90kWh of energy which is enough to power one HDB household for 1 full month. 
 
My take away point from this off campus learning is that having a superb plan to everything will help get the final achievement a lot faster and easier. 
I have also learnt the importance of recycling, reducing and saving electricity from this trip. After this trip i will try my best to recycle every recyclable items that i have and switch off all the appliance that are not in use to save electricity

Examples of such things are  how building infrastructure can  impact on the environment and ways to harvest clean energy so as to not harm the environment.  I learnt that the building is carefully planned as the toilets and lifts are located at the west side of the building.  This is because the sun rises from the east and thus the west side has the most direct sunlight. There are also solar panels in ITE which on average generates 90 KW of energy per day. Although it might not be able to generate enough power for the whole ITE, the energy is enough for some blocks. The power generated in a day in ITE can be used for an average household for a whole month. How crazy is that?! Not bad for some solar panels eh? The trip sparks my passion in energy saving and i have now learnt to keep my lights/fans off at home if not in use and reduce the using of air con. I am also aware of how the way a building is built can affect the temperature of the surroundings and long term efficiency of the management. like water being evaporated can cool down the surrounding.]]> 2018-07-31 16:06:24 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271569352 s10186947 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271573349 I’ve learnt alot in this trip to ITE college central. The host is able to present all the green features in the school and able to interact with us. From this trip, I learnt that the building designs, structure will also make an impact on saving energy. For example the solar panels facing south at 10 degrees. This maximises the heat energy reflected on the Panals and able to maximise the use of it. The plants on each buildings in the school is also built to face the West side so as to take in as much heat from the morning and afternoon sun to cool the place. The shelter, etfe, is also a good way to cool the building. Overall this trip is very fulfilling and breathtaking. It’s my first visit around the campus too so it’s really something  new to me. ]]> 2018-07-31 16:59:53 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271573349 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271652753 This trip to ITE College Central was really a very fun and interactive, with the guide explaining to us about the school's endless green features. At first, the guide discussed with us about how the school had a very open area concept, kind of al fresco. ]]> 2018-08-01 09:26:33 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271652753 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271669935 The trip to the Energy Efficiency Centre taught me lots of valuable things regarding energy conservation and management. I learned about the cost split between electrical appliances at home and how the air-con, water heater and refrigerator contributes to the bills the most. Problems such as a damaged refrigerator seal or leaving the heater on without the need to, causes unnecessary extra costs. All this helped me assess any problems I had at home with the electrical appliances and encouraged me to share this info with my friends and family who may face issues with electrical bills.]]> 2018-08-01 13:51:33 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271669935 s10186824 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271676279 After visiting ITE college central, i have learnt that building orientation can help in energy saving. The building is oriented in a way where east-west facade is being kept to the minimal. That way, it would reduce the amount of heat entering the building. By building non-air conditioned areas in the west facade, it can also help them reduce the amount of energy consumption. Plants have then been planted at the west facing facade turning it into a Green Wall which can help in cooling of the area and to reduce the energy cost. They also have building designs which complements the prevailing wind flow. There is also interlaced design which provides shade for the lower floors of the building. I have also learnt that by planting grass on the roof, it can reduce the heat absorbed by the ceiling which can lead to the floor below feeling warmer. The grass can also help reduce the noise level on rainy days. Overall, i really enjoyed this visit to the ITE as i have learnt something which i did not know about previously.]]> 2018-08-01 14:53:47 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271676279 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271735976 This learning trip to ITE has helped me in noticing the limitations of renewable generator, solar panels as the 740 panels can only provide a small sector of the power usage. The winning solution is probably the design and orientation of the building, they play a significant role in conserving the energy.]]> 2018-08-02 03:01:36 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271735976 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271736735 During the trip, I have learned the importance of building orientation.  ITE College Central built its building around Singapore's geographical situation. My biggest take away from this trip is how wisely they utilized the  North-South and Westside orientation. Since wind blows from the North to the South, they made a lot of naturally ventilated corridors which created a cooling effect throughout the school. Direct sunlight shines on the Westside. Hence, they placed toilets, wiring, lifts, and staircases as those places do not need to be air-conditioned. There is a green wall facing the West on every building which will help to cool down the building as well as the shallow ponds when water evaporates. Surprisingly,  the school has a community garden that is taken care of by the students and has won a platinum award by Nparks. There are a lot of small green initiatives done at ITE College Central such as recycling of electronic waste. Henceforth, new factories, residential, medical, educational, industrial, religious and military buildings must aim to go green. In order, to slow down climate change.]]> 2018-08-02 03:11:47 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271736735 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271747893 I am very interested upon hearing the announcement that we would have an off-campus learning at SP - Energy Efficiency Centre. Little do I know that the centre would be located within an office building. Despite its small area, it is a place full of knowledge waiting for us to explore and take in. During the presentation, I learned a lot about the electrical appliances that we use everyday in our homes. I was particularly shocked at the fact that an hour of air conditioning consumes electricity equivalent to having 20 powered fans.  After the presentation, we went around the centre to view various technological advancements made to reduce energy usage. I was particularly interested in the advancements of electric-powered cars. I expected the electric-powered cars to not be as efficient as conventional cars. However, electric cars can travel 90km to 150km for $6 of 'charging'. The distance is significantly higher than paying the same amount of money for petrol on conventional cars. Considering that 2018 is the 10th year of EMA, the test is close to a conclusion. I really hope that our conventional means of travel would be electric-powered as I believe that it will benefit both the population and particularly the environment. However, the question that just came to me ask I type this reflection is "How can the carbon emission produced by the production of electricity be reduced?". Since electric-powered cars requires a lot more electrical usage to charge the car, I'm assuming that more electricity would need to be produced. The current methods of producing electricity arguably produces a lot of carbon emission. Since more electricity would be needed, wouldn't there be more carbon emissions produced by the production of more electricity? Overall, the trip fascinates my interests as I've seen many forms of improvements on saving electricity and the many technological and architectural advancements made to contribute to reducing energy usage.

It also broke the common thinking of the modem router taking most of the household electricity usage, in reality, the air conditioner and refrigerator is the one taking the most and second most electricity respectively.
One interesting fact i learnt was that 80% of the electricity that we use comes from natural gas.
The Singapore Power employees also have to go to each individual HDB blocks to check and jot down the water,gas and electricity usage, it is quite troublesome but there's no other option , hopefully there's new technology soon that allows this process to be quicker and more convenient.
There's also electric car test-bedding in Singapore to see if there's any environmental and psychological effects. This is to test if replacing conventional cars with electric car will really help reduce carbon emissions and if the general public can accept the usage of electric cars.
There's also a model of a smart home in the SP EEC. It's basically a normal home but the big difference is that the user can control the electrical appliances at home when they are outside. 
Overall, all these technologies and applications help to reduce  net the electrical usage but there's room for more improvement. I hope the research on these clean technologies will proceed smoothly and even accelerate so these can be implemented into public places and even our homes as soon as possible.

We also learned about how to save energy and the different methods and systems that has been invented to help save electricity. I also learned about how much energy each appliance uses even when turned off. And most things still use energy when not even turned on. We also learned about the history of Singapore power and how it has evolved to provide power to Singapore. The electric grid has been controlled y the government for most of its history however now it has open to the open market to allow private companies to provide service to Singaporean residents.We also learned about the amount of energy that we use are non renewable, the most being natural gas which are imported from Malaysia and Indonesia. We also saw why Singapore hasn't fully adopted electric cars as a new initiative and are still taxing it higher than petrol cars, and its because the testing was until 202 so they do not know what the impact on the environment in Singapore electric cars have.Overall it was a good learning trip which i have gained insight into.]]> 2018-08-02 05:27:28 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271748349 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271757288 I have been to ITE College Central before but I did not know about their eco tour. Amazingly, there is a system to monitor power used in the whole college and able to display on a screen about the power of each building that is being used. The power provided from the solar panels are so less compared to the usage of power from the whole college. Even though there are 740 panels but it cannot provide more than 10% of the power that the school use. The way the buildings are designed are very effective and smart in a very 'green' way. The west walls of the college all have plants which makes use of the sunlight to the fullest. The plants are also organized well with those that are easy to maintain and look after at the lowest floor and those that can survive on their own without taking care of at the top. And then there is of course the rooftop with grass patch and more to use the sunlight to the max and reduce heat for the lower floors. The college also have a small garden with different plants and herbs grown like mango tree and mints and more.]]> 2018-08-02 07:32:53 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271757288 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271791932 The trip to ITE Central was an eye opener, i went there without expectations but what i took away with me were valuable knowledge. I went to the location by myself, the walk from the bus stop made myself drench in sweat as it was a very hot day. But when i reached ITE, i could feel cool breeze brushing over my body and i cooled down very quickly even though i wasn't near any aircon or fan. The buildings were built in staggered formation so that shadows of some building can provide shade of other buildings an the buildings were constructed in a way so that the air can be easily ventilated. As we walked along the school, i discovered a green wall thats similar to the one we saw at Changi Airport while doing the video assignment with my groupmates. The greenwall was west facing to reduce heat gain through the wall. The modular system also allows easy installation and maintenance. Mr Tan, our tour guide, also told us about the 740 solar panels installed in the school that collects enough energy to power a HDB household for more than a month, the solar panels were installed with  slight tilt so that there'll be selfcleaning system so dust and rain water will not be collected on the surface. He also mentioned that the greenroof reduces not only reduce heat to cool the building so that less energy is used to do that, but also reduces noise, which was something that i never thought of.(Grass absorbs the impact of the rain)
The glass roof of the campus were double glazed so that only light will be shone into the building to reduce the usage of electricity spend on light. Another cool feature i found in the campus was the tiny pool int the middle of the campus to cool the environment of the campus]]> 2018-08-02 15:21:53 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271791932 s10186382 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271797458 Min Rui
The trip to ITE Central was very fun and educational. I learn alot of things and more ways to be sustainable. Before the trip, i didnt think that i would learn anything meaningful or interesting but they proved me wrong. I learnt that the building orientation actually affects sustainability in a way.
Their building was planned before the construction and it has minimum direct west facing facade and it utilizes prevailing wind directions to achieve  adequate cross ventilation.
This allows the school to install lesser fans as the area in the middle of the school is cooler because of the wind. The buildings were also built close to each other so it will shade the sun.
They lcated their toilets, stairs and lifts at the end of the building which faces the sun so it uses natural lighting instead of using light bulbs which saves energy.  They have approximately 740 solar panels on the roof which are capable of powering 1 HDB flat for more than a month. They generate 550 kwh per day and are east west facing tilted 10 degrees, this allows self- cleaning to improve conversion efficiency.

They also have a green roof on top which is self watering using sprinkler system which is done every morning and evening as it is cooler and less water will evaporate.This green roof enhances storm water management, reduces noise transfer from the rain and cools down the ceiling.

They also have Daylight reflectors in School blocks which reflects sunlight throughout the room and minimizes the need of electrical lights.The staff centre on level 6 and 7 uses zoning,photosensors, motion sensors in offices.They also have Environmental Canopies which consists of the perforated aluminium panel & ETFE. They provide shelter to spaces below and they are 50% aluminium which provides shade. The ETFE has a leaf pattern which allows diffused natural daylight while still providing shelter from rain and has a double layer pillow system heat insulation.
After the journey, i learn that the ITE class rooms are better than the ones at NP and they use fans which are very quiet which saves energy.They also put their aircon on room temperature always and they always off their aircon after using the room.They have recycle bins everywhere and they try their best to promote recycling to their students.
All these efforts led them to win Platinum for the BCA Green mark Award. This trip really taught me alot of things and it is very meaningful and interesting. I didnt have any regrets attending this trip. ^_^

We went to ITE College central to learn about the different methods that they used in order to be sustainable. ITE College Central have numerous sustainable designs and have help saved a lot of electricity and water in the school.

This is essential as the areas which does not need cooling is facing the sun, so the classroom and offices which have air-con, do not face the sun, which means that the air-con do not have to use so much energy in order to cool the building down.
 I have also learnt that ITE College Central also have many green walls, which have plants hanging out and facing the direction of the sunlight.This help lower the building's temperature as it absorb the heat from the sun. In between the buildings are also many evaporation ponds, which are shallow ponds that help keep the building cool, which in turn reduces the energy needed to cool the building down. Their offices also allows for natural sunlight to enter from the roof, allowing them to save eletricity as they do not need to turn on their lights during the daytime. They have also implemented grass patches on the roof of some building as it helps absorb the heat from the sun and reduces the heat which the concerte takes, allowing the building to be cooler. The grass patch plants are durable plants as they have to be able to withstand heat and the soil is a type of lightweight soil, allowing for free draining and water to retain. They also water it only in the morning or evening if it is cooling to reduce the water wastage as the water may evaporate.
 ITE College Central also have a small garden which the gardening cca is in charge of, the garden is well maintained and is used as a way to educate students and guests about the enviroment. The garden have been awarded a platinum award. Beside the garden there is a barbecue pit which is a zero-energy building as it has solar pannels on its roof, which supply the energy needed to turn on the fans and the surrounding eletrical appliances. They also have many solar pannels placed on the school roof, around 740 of them, to collect energy and reduce their total energy consumption. They also have many glass roof which are Solar Control glass, which allows sunlight to pass through and reflects away a large amount of the heat.
 ITE College Central also has a huge moniter system which displays the energy usage of each block and the total usage of the whole school.This is a live system and shows the energy generated from their solar pannels as well. The energy generated from the solar pannels are so little compared to the total energy usage of the whole school. They also have many recycling bins placed all around the school to encourage students to recyle. They also have an eletronic bin, which allows students to throw their unwanted eletronic devices such as handphones and laptops, into the bin instead of throwing it into a normal rubbish bin, which would have waste the metal components inside the devices.
 I learnt that ITE College Central had planned extremely extensively on how and what they wanted the campus to be, and the many unquie types of green features and methods they used to help reduce their energy usage.

However, when I stepped into the vicinity of the ITE college central, I immediately realized that the students there does not look as menacing as I thought, some are even quite friendly! The environment in the ITE college central is also very pleasant as there are plants everywhere and although it is open aired, it is not as warm as it looks as there are energy saving technologies in place all over the campus to reduce the need of air conditioning by keeping the campus cool. There is also a stream flowing through the middle of the campus to promote evaporation which draws heat away from the campus, there are also green walls planted all along the west-ward facing walls in the campus to reduce the heat absorbed by the building during sunset. In conclusion, I am very impressed by the technologies that are in place there just to do a part to save the envir]]> 2018-08-03 02:39:45 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271849010 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271850521 This learning trip to ITE central has helped me in noticing the limitations to renewable generator,the 740 solar panels within the campus , could only provide a very small percentage of the total power usage.The winning solution is probably the design efficiency & orientation of the building which play significant roles in conserving the energy.The Eco-tour has taught me a few new things like fly-roof which 50% covered EFTE shelter (ethyl tetra-fluro ethyl) which is high heat resistant and provide right amount of sunlight and PV panels( photo-voltaic panels) which can produce 550 kwh/day and provide sufficient energy for 1 HDB building for a month. The various amenities are interesting as well, like green roofs,rain water harvesting, solar powered pavilion and green spine ,circular open window in the staffroom which these thoughtful designs indeed proven that the campus deserve to win the greenmark platinum award.]]> 2018-08-03 02:53:19 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271850521 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271861831 The trip to Singapore Power help me to better understand what do they really do behind the scene to help maintain and control Singapore Electricity. They also taught us how did Singapore electric changes from  past to present time and how they improve it to increase the efficiency of it to increase the standard of living in Singapore. They also showed how do would likely to go towards to increase the efficiency and at the same time to keep the environment clean to ensure that they do not destroy the environment. They showed as samples of solar panel to tell us how they would function and how it would prevent destroying the environment.

This helped me understand that we need to find new ways to ensure that even in the far future we would still have backup plans for our electricity even if our relationship with Malaysia or Indonesia turns sour.I also learned about how much energy each appliance uses even when turned off. Like how the fridge uses a high amount  of energy even if nothing is done to it. I learnt that some people turn off that fridge at night and store their food in the bottom section of the fridge and keep it cool by putting ice packs in there. I also learnt how air conditional uses up the same amount of electricity as 25 fans.Overall this trip made me become more aware of how we can save more electricity in Singapore.]]> 2018-08-03 05:07:30 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271862604 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271863094 So before going on this trip, I was thinking, the things that could be shown to us in ITE College Central would be very commonly seen/thought of when people talk about green buildings and anything related to it, hence I felt that I would enjoy the trip more if I was assigned to attend the Singapore Power trip. However, despite that, I still kept an open mind, secretly hoping that ITE College Central would have something up its sleeves to surprise me.

The bus trip itself to ITE College Central was nice in my opinion. The length of the journey added with the relative peace and quietness of my music and surroundings aided in calming and soothing my mind, preparing and conditioning me to absorb new information as soon as we landed at our destination.

Once we arrived at our destination, a playground immediately caught the eye of one of my classmates. It definitely is intriguing and amusing to see such a sight at an institute of higher learning. A short moment later, I felt a cool breeze graze past me – that’s when I realised, the structure of the bus bay was constructed to be wide and have a high ceiling, which I subsequently learned that it was constructed in such a way to channel the wind so as to keep the compound cool.

Next, we walked inwards, towards the heart of the institute, only to stumble upon a train stop that is seemingly integrated into the facility's compound. I suspect that this is done on purpose, so as to cut down on the carbon footprint of those commuters whose destination is the school itself. My explanation would be the fact that those people would not have the need to travel a further distance, either by foot or vehicle to reach the school as those activities not only consume time, but also adds to the commuters' carbon emissions, either through the direct emission of gases produced by vehicles, or the usage of energy by those people which results in them requiring to consume more food that upon production, emits greenhouse gases.

After a short bout of seemingly clueless wandering, we happened upon our guide as if by complete chance. After exchanging quick greetings, the guide revealed that he was assigned by the school to the department that manages energy (my memory is rather bad, I might have recalled this incorrectly, so take this piece of information with a pinch of salt.). His tone of voice made me feel as if, although definitely enthusiastic, he was slightly unwilling to be put in charge of this. In this day and age, its getting harder and harder to tell if he was serious about it or was merely jesting, and if he was sarcastic, it was completely lost upon me. Once the brief introduction, coupled with the showcase of the facility's energy production and consumption was done, he then brought us up to one of the many classrooms in this massive complex, to give us a summary on the many structures installed in the compound that helps green and enhance the facility.

During the walk up to the prepicked classroom, we walked on a "skybridge" of sorts, where I got to have a bird's eye view of some of the green features installed. I saw two things of note: The "garden on the wall" and the shallow but wide/vast man-made pools of water (it was actually three, but I didnt know of the importance of the third one until later during the lesson and walking up towards it closer).

The garden on the wall helps regulate the oxygen levels in the the complex that is covered by a very special roof that I will talk about later. As carbon dioxide is a greenhouse gas, it "traps" heat within it and therefore makes the air feel warmer. However with the "garden on the wall", carbon dioxide is absorbed by the plants to be converted into oxygen which subsequently cools the air as oxygen "traps" much lesser heat than carbon dioxide does.

The shallow man-made pools helps cool the air as it constantly evaporates to form a convection current, whereby air moves in a cycle. When air moves, it encourages heat exchange, whereby more heat gets "moved" from higher heat objects to lower heat objects. This would help cool the air and the buildings as heat gets removed from them with this current.

During the psuedo-lesson, the guide did bring up several interesting installations within the complex that were unfortunately off-limits to us. One such example is the green roof that simultaneously keeps the building cool and collects rainwater. The plants keep the building cool as dissipates heat much better than concrete through biological processes. The collected rainwater is purified via processes such as sedimentation and filtration, afterwhich said purified water is used for day to day use in the compound, such as watering plants and flushing the toilets.
Another example is the photovoltaic-cell panels installed on the roofs of some buildings. It helps to provide for some electricity that is consumed in the buildings, hence, reducing electricity waste as they can provide for themselves.

I personally felt that it would be nice if we could have obtained a copy of the slides presented as the presenter seemed to be rushing through some slides whilst merely glancing through some others. I know my opinion would vastly differ from others as I am the type of person that love to read a wall of text, rather than be presented with summarised points, however, it would still be nice to have such an option on the table. Simply put, I would've loved to be able to get in-depth details of everything that was shown to us.

After the "lesson" the guide then brough us up to the top floor (barring actually going to the roof) to have a look at the peforated aluminium panel and Ethylene tetrafluoroethylene installation in place of actual concrete roofing. Ethylene tetrafluoroethylene is a fluorine-based plastic. It was designed to have high corrosion resistance and strength over a wide temperature range. They school also used two layers of it with air in between the two so as to minimise heat transfer from within and outside if the school, keeping the interior cool. After that, he brought us to have a closer look at the "wall garden" and the community garden. The community garden is for educational purposes, with no pesticides being used. It also naturally provides food, shelter and safety to wildlife. It is built to have to have low maintenance, and the pool located within the garden uses sedimentation and filtration to keep the water aerated.

All in all, I went to ITE College Central with low expectations (not to be high and haughty, buts aying that I have completely no expectations at all would be a lie, we are always looking out or craving for something. Well at least I am.), and somehow came out dissapointed. Slightly saddened even, feeling that my time could be better spent elsewhere.

I am saying all these negative things, not because I am ungrateful for this opportunity to go on this amazing trip, but I am just speaking my mind, perhaps some things could be improved? Like going to places that have at least one unique feature (preferably multiple, if that can be helped). For example, Siloso Beach Resort has a swimming pool that uses natural salt instead of chlorine to keep it clean (maybe saline would be a better word?). They also have a built-in waterfall in their complex, which hydrates and cools the air. On top of that, they even have specialised support holes built around trees to integrate trees into their resort as it allows trees to sway in the wind without harming them.]]> 2018-08-03 05:15:43 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271863094 takeshinishiwaki333 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271863534 The Learning journey to Singapore Power was extremely interesting there were many things that I learnt about such as the importance of saving electricity. I also learnt about how air conditioning was one of the most energy consuming electric appliances and how it takes almost 30 to 40 percent of the average households electricity consumption. I also learnt that by saving energy we are also helping to save the environment due to the fact that energy is produced by power-plants that use coal as fuel which releases green house gases and other poisonous chemicals into our atmosphere. So by saving electricity we are doing our part to save the world and make our country and Earth cleaner and greener. I personally feel that what Singapore Power is doing is really commendable as they are trying to raise awareness among the youths about energy consumption and provide ways to reduce personal energy consumption.]]> 2018-08-03 05:26:23 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271863534 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271863676 Lim Zu Liang (S10177362B)

The learning journey to SP was very intriguing there were many things that you don't see everyday.
Additional, they conducted a electricity saving segment which was  very informative. One take away would be that,  WiFi routers, gaming consoles and TVs actually uses only 5% of the electricity expenditure in households, Air conditioning consumes the most electricity (30% - 40%). They thought us that by saving electricity, we are saving the environment as well. as the proccess to generate energy releases green house gases and other environmentally harmful gases. in conclusion, I think SP should conduct talks about saving electricity with the general public.]]> 2018-08-03 05:29:06 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271863676 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271894566 I didn't know what to expect when I first knew that we were going to ITE College Central for our off Campus Learning and I was excited as I had heard many stories about ITE in general, both good and bad, and wanted to know if any of those stories even could hold any water, especially since the recent murder case occurring there, I was eager to know how the school would react to this turn of events. Honestly I was pleasantly surprised when I went there as as soon as I got there, all those rumors and felt more and more like fairy tales than actual fact, the atmosphere of the school felt very welcoming as some kind of school event was happening near us with the cheers of the students echoing through the campus, and I immediately felt the 'humanity' of the place, not through the eyes of newspapers, or tabloids, and I could feel a sort of connection, that the people there are not much different than you or me, that their just people trying to enjoy their time here and get through the bad, just like you and me.

I just realized that I rambled on about the feelings the trip gave me but not about the trip itself, we learned more about the importance of building orientation when designing a building and how you can use the environment to ease the use of resources on the building for example, the building's orientation allows it to block out the sun at certain parts of the building to make those parts cooler and spend less energy on fans and air cons, likewise the grass on the roof of the building is to absorb the heat coming onto the building and make the upper floors easier to cool. The orientation also helps to position their greenery and solar panels, the greenery can face the sun to get light more efficiently as well as the solar panels which tilt to aid in maintenance of the solar panels so puddles won't form and block the sunlight. We learned all this from the main reason we were there which was the eco tour that brought us around the campus to show us the different ways the the campus conserves energy such as efficient lightning that dims when it senses there is enough natural light to light up the room, saving energy. ETFE(Ethylene Tetrafluoroethylene) which is basically for heat insulation as well as trying to educate students on saving energy like electronic recycling bins and 'green' posters.

All in all, I thought the trip was interesting and would like there again but under different circumstances.]]> 2018-08-03 15:02:29 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271894566 shengwei29 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271899065 The trip to ITE was meaningful and surely an interesting one for me. The most interesting point i found out was that the ITE college central has 720 solar panels that tilts 10 degrees to absorb maximum amount of sunlight and to self clean itself as the water would just slide of the solar panel. Moreover, although they have 720 solar panels in the school that can provide the amount of electricity that can power a HDB flat for a month in a day, it only provides about 5% of the whole campus total energy usage daily. I was also  of their roof and living green wall. I find that the roof design of making 
use of natural light to reduce energy usage on lighting and also to have plants and grass on the roof to reduce heat emission is being very energy efficient as this reduces energy usage for air-con and lights. After the visit to ITE central, i became more interesting in learning about more ways of innovative and effective ways to be more energy efficient.

The trip to EEP was really interesting since I had started off without even knowing what EEP was, what it stood for or what they did. In a lot of ways, though we all know that electricity is supplied to our houses and all we have to do is pay the electric bill, there's very few people who even know how exactly energy is generated or even how Singapore is able to provide its citizens with electricity with already being a small country.  There we learnt how electricity is generated in a power plant, is transported to a power grid and is then ready to be supplied to the public. We also learnt how to read electricity meters, water meters and gas meters. However, I think the part of the tour that I personally found most interesting was when we were introduced to the concept of electric cars in Singapore. Even though its such such an environmentally beneficiary movement, we were told of the many limitations that acted as barriers from preventing the electric cars industry to grow in Singapore, the incredibly high taxes for electric car companies being one of the major reasons. Also, knowing that Singapore intends to build and sell homegrown electric cars is exciting for my generation since by the time that the cars are released, in 8 years or so,  we will be the ones who are the target demographic. In conclusion, the trip to EEP was eye-opening and I would actually look forward to work for an internship with them.

Later then i realized that the ITE CC is east-west orientated and there are many greenery in the building to cool it down and reduce heat gain. Eco features such as naturally ventilated corridor and green spine to reduce heat gain and keep the building cool. They design the building such as locating the toilets, staircase and lift at the west side which has the most heat and the classroom on the other. Photo-voltaic (pv) panels are installed at the rooftop, it has up to 740 solar panels. they are all 10 percent tilted to the sun to gain maximum energy. It is also requires low-maintenance as when it rains, the rain water will slide down the pv panles and clean them. Even though many pvs are installed, however, the amount of power generated could not even cover a quarter of the total usage by the whole campus. Thus, they are planning to install more pvs in the future. This trip really make me gain lots of experience, at first i thought that the 740 pvs could cover at least half the total usage but i was totally wrong. This also made me wonder how can the pv panels be more efficient in generating power per day. Challenges such as space and cost could also affect the installation of pv panels. In conclusion, it was an enjoyable trip and i took away lots of learning objectives.]]> 2018-08-04 16:03:45 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271952827 https://padlet.com/ykgatnp/CEM18_OCL2/wish/271989250 The trip to SP was a meaningful and enjoyable one. I got to know what SP EEC is all about. Before going to the place I knew that aircon was the one of the appliances which takes up most of the energy but I learned that it takes up to 40% of the average household energy consumption which shocked me. The guy who was showing us around the room gave us energy saving tips and taught us how to read bills ( electricity, water & gas) which was beneficial. We learnt how electricity is generated via powerplant and is transported to a power grid and finally supplied to the public. The part that most interest me was the smartplugs at home which you can control your appliances when you are outside. For example you can choose to on your washing machine from 2pm to 6pm (less energy is being used at this timing) while you are still at work. This helps to save energy as well as money. Electric cars are being tested to see if it will help reduce the carbon emissions and whether it will result in positive impact on the environment. Moreover, electric cars can travel much more distance than a normal conventional car. Furthermore I learnt that energy market will expand in the upcoming months which I believe that it will increase awareness in people on the importance of energy consumption. Overall I gained knowledge from the trip and hope that SP power will conduct talks to every neighbourhood so that people can know the importance of energy and will start to consume it probably. ]]> 2018-08-05 14:29:50 UTC https://padlet.com/ykgatnp/CEM18_OCL2/wish/271989250
