University is full of possibilities. It is the place and time for young adults to challenge themselves to learn and to make a positive difference in community. That's why Blue Sky does more than energy monitoring and real-time display in the four Colleges of HKU JCSVIII.

We harness the power of granular data to empower residents to adopt lasting behavioral change. With mentorship support, students go on a journey to gain insights into their College's energy data and implications. Discovery of the existing energy usage pattern is key to identify energy saving and improvement opportunities. Students gain a broad spectrum of skills including data analysis, data visualization and user-centric design thinking throughout the program. Every student participant takes part in the research, design and pitching of initiatives that benefit the whole College.


Blue Sky implemented a pilot in 4 floors of HKU New College in 2016. In 2018, we expanded services to all 4 residential halls in the Jockey Club Student Village III of the University of Hong Kong, which covers a total of 1,800 students.

  • 1276 rooms and 90 student lounges

  • 100+ Multi-circuit breakers

  • Real-time energy display in concourse, visible to 1800 residents

  • Personal log-in account for residents for web dashboard & smart phone app

  • Data granularity of individual room and pantry, separated into air conditioning, light and socket load

  • Notification and Alert which prompt energy investigation

  • Weekly consumption report for energy review

PILOT Result

New College residents become more aware of their energy use throughout the program. Resident awareness increases by 44%. Meanwhile, energy consumption in Room and Pantry AC, Room light and socket has reduced by more than 20%.


College residents gained insights into their energy use through the semester-long engagement program. This includes an in-depth analysis of the College's energy data. A series of workshops are deployed to equip the residents with ability to use data analytical tools and adopt user-centric design thinking.

Past workshop topics include:

  • Data Analysis tools and case studies

  • User-centric Design Workshop

  • Pitching 101

  • Making Infographics

  • Data Visualization with Open Source Software

We also invited a broad group of seasoned professionals to serve as mentors and speakers to inspire and share their experiences with the residents. Our past workshops featured sustainability consultant, venture capitalist, foundation head, green advocacy group program manager, architect and industrial designer.



Residents also showcased the analytical results of the energy data, carry out research, design and pitch a series of college-wide sustainability initiatives. New College Master Dr. Sarah Liao and guests review the teams’ pitches and provide feedback. Fellow college residents are also present to evaluate the results, and to jointly decide on the initiatives to implement in the following semester.
