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.
