Innovating for Sustainable Cities

Projects in this theme delve into the challenges of urbanization and sustainability. It focuses on two broad themes: (a) improving livability in the urban environment, and (b) management of limited resources such as water, energy, and land in an efficient and sustainable manner. This theme explores how engineering innovations and solutions can be shaped to address these complex and grand challenges in a holistic manner so as to improve the way we live, work, travel and play while protecting natural environments.


Autonomous Robot for Nursery Plant Maintenance

Horticulture is a labour-intensive industry as it requires careful and rigorous maintenance of plants that are grown for various purposes. We were approached by a client to create a robotic solution to the plant maintenance work in their nursery. The client desires to increase their operational efficiency by reducing man-hours spend on simpler tasks such as watering by 30 % so that the horticulture team has more time to focus on specialized tasks such as pruning.

Verdana: Solar-Powered Cooling Device for Homes

Most Singaporeans leave their homes shut for most of the day while they are at work/school. Over the day, the air inside the home heats up but remains trapped. As a result, occupants return home to a hot, stuffy, and uncomfortable environment at the end of the day. We aim to build a device that can remove the hot air trapped inside a home and replace it with cool air, fully powered using renewable energy, so that occupants can return to a well-ventilated and comfortable home instead.

Solar Cooler

Lack of access to affordable refrigerators and electricity especially in the less-developed countries is contributing to the increasing global food wastage. This project aims to provide a low-cost, compact solution for cooling food items. The designed prototype uses urea as the coolant due to easy availability. The design of the device allows operation without any electricity operation.

Water Contaminant Detection System using UAV as a platform

It is crucial for PUB to monitor raw water quality in the reservoir to ensure safe water from source to tap for the public. However, there is no current solution that can provide real-time, location-specific water quality monitoring with contaminants characterization.

Generating Power through Heat

Lack of access to electricity is a problem in a lot of rural regions. As an alternative to solar panels, harnessing waste heat, especially cooking waste heat due to its wide availability, is a viable solution to this problem. A Stirling engine was developed, which is able to generate a useful amount of electrical power from cooking waste heat. A complementary real-time testing system was also developed to display the temperatures, flywheel rotating speed, output voltage and power of the Stirling engine.

Future Mobility Solutions for Transit Integrated Development

With the government’s recent push towards a Car-Lite society, the onus is on engineers and designer to come up with a transportation system that supports this goal and yet attractive enough for commuters to use. Our design solution is a transport system which encourages active mobility within the “Gateway” district of JID.

Energy Innovation Challenge

This theme rides on the Energy Innovation Challenge organized annually by the Institution of Engineers and Science Centre Singapore, and other similar competitions. Students are expected to design and invent a product to demonstrate the use of alternative sources of energy.

"Smart" Cool Ideas for Better HDB Living

This theme rides on the "Smart" Cool Ideas for Better HDB Living contest organized annually by HDB, and other similar competitions that are driven by Singapore's Smart Nation initiative. Students are expected to identify problems with day-to-day living in HDB estates, come up with innovative and “smart” ideas to tackle these problems, and prototype their solutions. Projects may be aimed at the household or estate level.

Smart Structures

This theme looks into new structural designs and construction technologies that can improve the quality, productivity, operation and safety of civil engineering works. Examples of possible projects include structural systems that enable rapid and modular construction, and sensors for monitoring and improving structural performance.

Smart Solar Sunshades for HDB Households

This project aims to reduce the thermal load caused by solar radiation in Singapore HDB households. The team is developing a solution that can be deployed in urban households to absorb the abundance of solar radiation, convert the radiation into usable forms of energy and store the converted energy for later use. A servo motor is used to rotate the solar panels according to Sun’s trajectory.
