Energy Wastage Identification
SDG 7.2.5
At Sunway University, annual Internal Energy Audits are undertaken across campus buildings to systematically review energy performance, identify areas where energy waste is highest, and prioritise corrective actions. These audits form a central component of the University’s energy management approach, ensuring that inefficiencies are identified and addressed in a timely manner.
Key findings from past and ongoing reviews, together with the actions taken, are summarised below:
Year/ Commenced | Audit Findings | Action taken |
2016 | Lights and air conditioners left running in unoccupied classrooms after the last use of the day | Red indicator lights installed outside classrooms/rooms for clear identification of electricity usage. Security patrols instructed to manually switch off units when not in use (2018). |
2017 | Printers left running continuously during non-operating hours | Printers progressively replaced with multi-function models equipped with automatic energy-saving mode when idle (2018–2019). |
2018 | Corridor and toilet lights left switched on from 7.00 a.m. to 10.00 p.m., even when unoccupied | Cleaning and security staff instructed to switch off non-essential lights; lights only switched on when areas are occupied (2018). |
2018 | Water boilers in pantries operating continuously, including non-operating hours | Timers were installed to automatically switch off hot water boilers after office hours (2019). |
Annual Review | Non-essential lights in low-use areas (toilets, corridors, pantries, unoccupied offices) |
|
Annual Review | Non-efficient light fittings in common areas | Retrofitting of LED lighting across corridors, rooms, and offices to improve efficiency (2022–2024). |
The University has also addressed energy wastage from information and communication technology (ICT) equipment. By 2023, all staff and laboratory computers, which are energy-efficient machines, were configured to automatically enter sleep or hibernation mode after periods of inactivity. Printers were likewise set to enter energy-saving mode during idle periods to further minimise unnecessary electricity consumption.
Beyond ICT, significant progress has been achieved in upgrading to energy-efficient fittings, equipment, and appliances across campus. As of 2024, approximately 95% of all appliances in use are energy-efficient models. In particular, all staff computers and computer laboratories have reached 100% energy efficiency, while air conditioners have achieved 77% energy efficiency through systematic retrofitting and phased replacement. The University continues to seek continuous improvement in energy management practices to further strengthen operational sustainability.
