7.2.5 Energy wastage identification

Excessive energy consumption represents significant operational inefficiency and environmental impact. By systematically identifying points of energy wastage through an energy review, we can develop targeted strategies to optimize resource use. This effort is central to achieving our sustainability goals and reducing unnecessary expenditure.

Based on the graph showing electricity consumption at Srinakharinwirot University by area, it's evident that Ongkharak campus consumes significantly more electricity than Prasanmitr campus, roughly 29.3 million units compared to 20.4 million units.

This clearly indicates potential energy wastage or significantly higher electricity demand at Ongkharak. Therefore, the university should prioritize investigating the causes and finding ways to reduce energy consumption at the Ongkharak campus to address this energy wastage.

The graph illustrates Srinakharinwirot University's electricity consumption throughout 2024 by month. Peak consumption is observed in March, April, May, and August-November, likely correlating with academic periods or high-activity phases. December shows the lowest usage. Identifying these high-consumption periods is crucial for pinpointing potential energy wastage and implementing targeted management strategies or technological improvements to reduce it.

The graph presents electricity consumption by area (Prasanmitr and Ongkharak) and month at Srinakharinwirot University. Ongkharak campus consistently shows higher electricity usage throughout most of the year, especially from February to November, aligning with academic terms and higher demand than Prasanmitr. This significant disparity highlights a substantial opportunity for energy reduction at Ongkharak, potentially through system audits, equipment upgrades, or promoting better energy-saving habits to address "Energy wastage."

This graph shows electricity consumption by building at Srinakharinwirot University (Prasanmitr Campus). The "Central Buildings and Areas, SWU Prasanmitr" exhibit the highest electricity usage, nearly 8 million units, significantly more than other faculty buildings. Followed by the Faculty of Science and the Faculty of Dentistry, the central area's dominant consumption suggests substantial potential for identifying and reducing energy wastage there. Efforts to improve cooling systems, lighting, or shared equipment could lead to significant energy efficiency gains.

According to the graph, the "Waste Treatment Plant" at Ongkharak has the highest electricity consumption, nearly 10 million units, followed by the "Welfare Office behind Building 9" and the "HRH Princess Maha Chakri Sirindhorn Medical Center." The waste treatment plant's exceptionally high usage suggests potentially inefficient processes or highly energy-intensive equipment in waste management. This points to a critical area for immediate investigation to identify and reduce energy wastage, particularly by assessing the efficiency of the machinery and systems involved.
