Showcase Presentation: Water-cooled Facade Wall

According to National Environment Agency (2015), the ideal indoor temperature is 25 °C. Many Singaporeans, including HDB flat dwellers feel uncomfortably hot as the indoor temperature increases due to the heat being trapped particularly on the east and west facade walls. As a result, people tend to switch on the air conditioner and fan causing an increase of energy consumption.

The team proposes water-cooled facade walls to reduce indoor temperature. A water-cooled facade wall utilises harvested rainwater to flow through PVC pipes which are embedded inside the walls. The rainwater collected and stored in the storage tanks at the rooftop will run through the PVC pipes using gravity feeds and will be pumped back to the storage tank to be reused. The pump is powered by the solar panel that is installed at the rooftop. This cycle will then sustain.

My team was selected to present our proposal to the entire SIE cohort. We were in high spirit to be selected by our Professor as it was an opportunity to showcase our work to the government organisations, SIT course directors, SIT professors and my fellow course-mates. Before the presentation, I was extremely nervous as I would be presenting to a new group of audience. But thanks to my professor and classmates for being there to give us moral supports for my team and I.

I enjoy doing this assignment with Jun Jie and Jason! It is a fun and memorable learning experience with them!
