MEASUREMENT & ASSESSMENT
Electricity Dashboard / Equipment Dashboard
The Office of Sustainability has analyzed electricity consumption in buildings and created an electricity dashboard using Tableau. The dashboard aims to identify energy consumption hotspots. NTU has identified where and when electrical devices (like AC and servers) are being used. It will be helpful in reducing energy consumption.
NTU Electricity Assessment Report (2023 , 2025)
In 2023 NTU undergoes and holistic analysis of campus electricity consumption. It documented past efforts on energy wastage identification, including the collaboration with outside consultancy on 34 "Building Energy Efficiency Assessment" Reports. The report identified 53 buildings that have an EUI higher than 100 and do not have a great difference in electricity consumption between daytime and nighttime. These buildings consume 68% of all electricity from NTU and are listed as priorities for improving energy efficiency. (Page 10~11). The biggest contribution of the 2023 report is identifying the electricity-using pattern of each building to design specific energy efficiency improvement actions for different kinds of buildings. (Page 12)In 2025, there was an updated version of the Electricity Assessment Report. The main improvement is creating a Building Electricity Indicator. The basic assessment tool of using Energy Usage Intensity (EUI) is no longer sufficient. The new indicator can better allocate the purpose of the consumption of electricity into four groups: building basic, off-hour equipment, daytime air con, and daytime equipment. (Page 6) Through these four groups, the electricity usage pattern of each building is better understood, and the hotspots will be better spotted.
