On 30 July, our YEA attendees had a site visit to the Hong Kong University of Science and Technology, guided by Professor Arthur Lau, the Associate Professor of the Division of Environment and Sustainability at HKUST.
During the visit to HKUST’s central cooling system, our attendees learned about the use of heat pumps to generate electricity, which is several times more efficient than conventional methods. The system repurposes the heat generated to boil hot water for showers within the university, demonstrating over 20 years of sustainable operation with 9 chillers. This advanced system uses eco-friendly refrigerants that are safe, non-flammable, and have a low global warming potential, making them third-generation refrigerants.
Following this, our YEAs participated in the Personal Footprint Workshop, where they explored both water and personal carbon footprints. The median carbon footprint per person in Hong Kong is 3.9 tonnes, highlighting the need for individual action towards sustainability.
We were then introduced to the Smart Sustainable Campus at HKUST, featuring cutting-edge technologies such as an AI tray detection system to monitor food waste, a WELL water spring, and an aquaponics system at the university. The campus also boasts EV charging stations, smart parking system and a significant solar panel installation, second only to Hong Kong Disneyland.
This field trip provided our YEAs with invaluable insights into sustainable practices that drive HKUST’s commitment to environmental stewardship. A big thank you to HKUST for hosting us and sharing their inspiring initiatives!
