Here's the problem statement we chose: How might we increase the use of renewable energy of either residential communities or industrial facilities? We specifically targeted to implement renewable energy in our air-conditioners. This is so as it forms the majority of an average household’s energy consumption and Singapore’s tropical climate, making the use of this energy draining appliance a necessity.

The design thinking process encompassed the 4Ds, discover, define, develop, deliver. In the discovering and defining phase, we dissected our problem statement and refined it thoroughly. Deep analysis of our various stakeholders, especially the residents who are our main target audience. We analysed their behaviour and varying thoughts to eventually identify similarities, specifically their concerns on the cost and convenience in implementing renewable energy. Next, in the develop phase, we further broken it down into 4 key components, first, broadening through listing potential ideas, second, narrowing as we down select the ideas, third, contextualising as we align the ideas towards our main goal and finally looking back as we recap past ideas that can play a small role in our end product. Finally, delivering as we present our proposed prototype together with our marketing strategy for it.

After this vigorous design thinking process, we came up with a moss powered air-con through harnessing biomass energy from it. It involves using moss as a source of energy to power the air-conditioners. But this will also be a hybrid system where some energy will be from the moss and some from the traditional energy source we rely on due to the relatively low energy harnessed from moss. However, having said so, we believe that further research can be carried out to harness a greater proportion of the moss’ energy.

If we had more time and resources, we would like to improve on implementing the actual prototype. As with a very low proportion of energy harnessed, it will not be able to fully power an air-conditioner as one will require a lot of moss in that case which is not feasible in the context of HDB flats. But instead, we might have considered implementing it to the industrial sector instead where with bigger factories there can also be more room to implement this moss energy for example on the walls of the factories that are left untouched by the big equipment. Or even in malls actually. But in essence, we hope that we could have looked more thoroughly into implementing this idea in industrial areas like malls and factories as it may be easier to implement it there instead due to the relatively greater wealth of space on the walls.

We would also like to mention that while this is a novel idea, there is still ample room for improvement on the technology itself. And while it may seem far-fetched in implementing this technology in large appliances like air-conditioners, we can always start small like implementing them in smaller devices like a handphone charging port. Regardless of scale of implementation, as long as we can implement renewable energy somewhere, it is still a step towards a greater tomorrow.
