Electricity Consumption in Higher Education Buildings in Thailand during the COVID-19 Pandemic

The COVID-19 pandemic forced higher education institutions to switch to online learning for most of 2020 and 2021 for the safety of their students and staff, which significantly impacted campus resource consumption. This study aims to analyze the changes in electricity consumption in higher education buildings based on comparisons of three academic years to understand more about the energy implications of the post-COVID-19 era. The electricity data were collected from 181 samples of the electricity meter records at Chulalongkorn University, Thailand. When compared to the typical academic year in 2018, the results indicate that electricity consumption in 2019 and 2020 decreased by 20.92% and 35.50%, respectively. The academic and the library-type buildings marked the biggest change in electricity reduction. The smallest change was found in the research type as its essential work remained on campus. Only electricity consumption in the residence type increased due to the long periods of online learning policies. Finally, the findings suggest that teaching and learning activities have a strong influence on electricity consumption in higher education buildings. The facilities and learning methods related to these activities should be carefully discussed as elements of an effective strategy to manage electricity demands at the university level.
