Technical Report: Individual Presentation Oral Pitch

-

With the idea that there was no cooling system in Clarke quay, our goal, as solar impact , to make an impact,  was to propose to the management team of CapitaLand to  implement a solar panel rainwater cooling system, which allows for light to be reflected and absorbed into the solar panels. The rainwater harvesting system will be used to cool the panels down in the event of overheating. The purpose of this cooling system on the rooftops of Clarke Quay shophouses, is to help in reducing the effects of UHI through achieving our goal of being more energy efficient and sustainable. With the mitigation of the effects of UHI in Clark quay  & through using this improved and efficient integration system proposed, we strongly believe that  it will allow Clark quay of being able to be awarded the green mark gold plus accreditation. ( A green mark score of between 90 - 100, “which indicates how sustainable and energy efficient a building is operating in the environment)

With the solution in mind to tackle overheating in Singapore, our group did a through research through the market and found that this idea was not entire entirely new. The successful implementation of the solar panel and rainwater harvesting system had been done before, one being in USA and one done locally in Singapore.

Modelling of this system has been proposed in America. Students from the University of Massachusetts (meh - suh - choo - sits) proposed a solar panel rainwater harvesting system on the parking canopies of the University of Massachusetts to promote campus sustainability. 

After their calculations and research done, this integration of solar panels and rainwater harvesting would allow the university to save around 5,300 dollars a year on electricity bills, and even increase the solar panel’s energy output by up to 20 percent.

Another successful implementation is done locally here in Singapore. Sembcorp opened the nation’s first solar farm with an integrated rainwater harvesting system to achieve its long term net zero aspirations.

This farm has a modular and flexible design and uses mobile solar panels that can be readily redeployed in 6 months if the land used is needed for other purposes.

The collected rainwater will be used for non-potable purposes, like cleaning and cooling the solar panels on site. This system produces over 22,025 megawatt hours of power annually, which can power about 4681 four room HDB flats. Using solar energy will also result in a reduction of 8,900 tonnes in carbon dioxide emissions.

This solar farm proves that the integration of solar panels and a rainwater harvesting system is can be a sustainable, viable and feasible idea in Singapore given the proper support by the companies and government.

With the introduction to our proposed solution, Timothy will now be proceeding to share about this integrated system and the benefits of it.

WEEK 2: FORMAL INTRODUCTORY LETTER

Dear Professor Brad, My name is Moong Yen Jee and I am writing to introduce myself to you. I am currently pursuing a degree in civil engineering at the Singapore Institute of Technology (SIT). I earned a diploma in civil engineering with business from Singapore Polytechnic (SP). The fact that I can speak Cantonese well is an intriguing truth about me. Since young, mathematics has been my favourite subject as I have always found the calculation of numbers, logical equations, and solving mathematical problems to be fascinating. My interest in finding creative answers to issues stems from the idea of merging math and logic, is what inspired me to pursue engineering. I made the decision to continue my engineering studies because I was interested in the structural side of engineering and was motivated by my father, who has been employed in the field for a long time, after observing the positive effects he had on those around him. One of my communication strengths is the ability to rea

TASK 3: THE IMPORTANCE OF COMMUNICATION SKILLS FOR ENGINEERS

“I contend that we (engineers) are undervalued because of our widespread inability to explain what we do to the general public (and why it is so important). It is one of the hardest goals to accomplish, to be able to boil down difficult concepts into a short and easily understood presentation or elevator pitch.” Marybeth Miceli, President, Miceli Infrastructure Consulting, USA (2011) According to Marybeth Miceli, the work of engineers is often unappreciated, and deemed insignificant, as engineers themselves struggles to bring across their scope of work and ideas clearly to the general masses. This is compounded when such condense, complex descriptions are not properly translated into simple, brief and understandable presentation or persuasive speeches that can spark the interest of listeners. In my opinion, I agree with Marybeth Miceli to a major extent that the engineers' work is often unrecognized among the general masses. This is exacerbated with the lack of understanding, discu

Summary Reader Response Draft #4

Tunnels in the past were utilized for purposes such as irrigation, drainage, and water transportation system as well as communication routes to improve the underground habitats to improve the standards of living. The Leonard (2022) webpage titled, “Innovation at the end of the tunnel”, informs readers about the rising need for underground infrastructures brought on by population pressure and urbanization. This underground infrastructure includes functions such as sanitation, logistics, and transportation. To meet these demands, modern tunnel-boring machines were introduced to meet these needs. As mentioned in another webpage by Trenchlesspedia, (2020, para. 2), tunnel-boring machines are referred to as “mole(s)” and are designed to bore circular tunnels through all types of earth, from sandy soil to hard rocks. The recently completed construction of the Thomson - East Coast Line (TEL) in Singapore is an excellent example of how this technology is being extensively utilized (Wong, 2019)
