Since the implementation of control measures and capability building programme in 2012, the electricity consumption per member of the school was reduced significantly from 1,838 kWh/head in 2012 to 1,577 kWh/head in 2013 and further to 1,116 kWh/head in 2014, representing an average annual reduction of about 20%. The school obtained the BCA Green Mark Gold Plus Award in 2012 and the School Green Awards (Lotus Award) in 2014.

Results

Control Measures

Air-Conditioning System: To reduce electricity consumed by the air-conditioning system, the school limited the operating hours and temperature setting of air-conditioners. The air-conditioners in classrooms were only switched on during the hotter parts of the days, while those in the staff rooms were programmed to progressively shut down from mid-afternoon as teachers left the office. The usage of air-conditioning at the Indoor Sports Hall and Multi- Purpose Hall was limited to key school events.

Lighting: To minimise wastage, lights at common areas were controlled by timers while those in the restrooms were controlled by motion sensors.

Capacity Building

Staff: Staff attended environment-related workshops such as the Environmental Education Advisor Networking Sessions, and worked with partners like A*STAR and Greenpac on energy efficiency projects to build their technical capability in energy efficiency. Regular updates on the school’s progress in meeting the electricity reduction target were also provided to staff to raise their awareness on the school’s EE efforts.

Students: Value-based environmental education was integrated into school programmes and customised to meet the varying interest levels and abilities of the students. Students who have the passion and aptitude, would participate in the school’s Talent Development Programme on Environment Education.

Project Description

SST’s campus is relatively new and is designed with green features that are not typically seen in schools. These include: (1) water-cooled VRVs for the administration block, (2) central controls for air-conditioning, (3) 53kWp solar panels, and (4) lighting and fan electrical circuits grouped in clusters, with prominent layout plans showing the switches that allow users to switch on only what they need. Complementing the energy efficient design of the school campus are strict control measures on electricity usage, along with staff and student capability building programmes.
