Sustainable Features of the Campus

To understand how much electricity and water is used on campus Island School’s environmental group, Wanbo, has implemented a monitoring system, Entrak. The team also worked with the ESF engineers including Head Engineer, Mr. Michael Lee, to monitor the air quality around the building. This report summaries their findings.

Lighting and Energy

The classrooms are fitted with sensors so lights come on and off when a student enters or exits a classroom. Another feature of our classrooms is the temperature system which is controlled by a refrigerant volume system. A monitor sensors when someone is in a room and the temperature is lower to 24C (on warm days). The temperature increases to 27C when no one is in the room. We also have other features such as solar panels & a wind turbine which saves the school $8per day per classroom.

Air Quality

The quality of air that students breathe was a top priority for the building’s engineers. For classrooms and general areas, Nitrogen-Carbon Dioxide (CO2) sensors kick in once it reaches a certain level. This initiates an extraction fan system, extracting stagnant air and bringing in new air.

Water Management

The lower floors of the school house machinery which holds the water filters & rainwater management system as well as a water cleaning system for the swimming pool. The water filters in our school are specifically designed for the toilet flushing system. A complex network of drainage collects rainwater and stores it in large tanks beneath the building. This water is then directed to the toilet flushing system.

The swimming pool has a system that will adjust the temperature of the pool on a seasonal basis, cooling the water in the summer while maintaining the temperature during the winter months.


We hope this report gave you a rough idea of how our school is currently tackling the biggest environmental issues. The Wanbo team will continue to share examples of how we can become a more eco-friendly school. We are .looking to recruit new members. If you would like to volunteer, please contact Mr Burrough (ross.burrough@online.island.edu.hk). Spaces on the team are limited, so early sign-up is advised.
