MEASUREMENT & ASSESSMENT
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.
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)
NTU had set up more than 600 smart meters to upload its electricity consumption every hour. These data helped the school manage NTU's electricity consumption and also identify energy waste.
NTU has 12 buildings certified by
EEWH, with 4 EEWH Silver buildings. There are nine indicators in EEWH with "Energy Saving" having the highest weighting of 32%. Energy Saving includes energy-efficient building envelope (EEV), energy-efficient air conditioning (EAC), and energy-efficient lighting (EL).
