Key driving forces of energy consumption in a higher education institution using the LMDI approach: The case of the Universidad Autónoma de Chile.
Energy consumption in universities is a crucial issue as they aim to balance growing operational demands with environmental sustainability. This study employs the Logarithmic Mean Divisia Index method to assess energy consumption variations at Universidad Autónoma de Chile from 2017 to 2022, demonstrating the method's efficacy and simplicity in decomposing energy use into its determinants. The analysis reveals a 19% increase in energy consumption, primarily fueled by heightened energy intensity from increased research activities and rising enrollment. However, weather conditions and infrastructural efficiencies have mitigated this increase. Notably, the 2020 remote learning period saw a 45% decrease in energy consumption, largely due to reduced energy intensity. This study validates the LMDI method for individual institutions and provides a clear, interpretable framework for understanding energy variations. It highlights the impact of the Chilean accreditation system, which indirectly induces energy consumption expansions in universities by requiring enlargements in gross floor area. The findings also emphasize the significant effect of weather on energy usage in extreme climates. Recommendations for Universidad Autónoma de Chile include implementing behavioral change programs, enhancing climate control, and lighting systems, conducting energy audits, pursuing building retrofitting, and considering a partial shift to remote learning to further reduce energy consumption.
期刊介绍:
Applied Energy serves as a platform for sharing innovations, research, development, and demonstrations in energy conversion, conservation, and sustainable energy systems. The journal covers topics such as optimal energy resource use, environmental pollutant mitigation, and energy process analysis. It welcomes original papers, review articles, technical notes, and letters to the editor. Authors are encouraged to submit manuscripts that bridge the gap between research, development, and implementation. The journal addresses a wide spectrum of topics, including fossil and renewable energy technologies, energy economics, and environmental impacts. Applied Energy also explores modeling and forecasting, conservation strategies, and the social and economic implications of energy policies, including climate change mitigation. It is complemented by the open-access journal Advances in Applied Energy.
