TKU introduced ISO50001 in 2015, enabling organizations to establish systems and processes to improve energy performance, including energy efficiency, use, and consumption. It is suitable for different organizational forms and energy use requirements, including performance supervision and measurement, documentation of important management processes and performance reports, equipment design and procurement processes, etc., to demonstrate compliance with regulations and stakeholder requirements. The university conducts energy review operations on each campus every year following the requirements of the ISO50001 energy management system, to spot energy-intensive units and equipment, and further implement energy consumption management. In the past five years of operation, we have spotted and improved the main causes of electricity consumption on the campus (for example, the top 20 electricity-consuming units). Through the 80/20 rule, we have implemented and internalized the energy baseline, energy performance indicators, and other inspection tools to the general affairs units of each campus for continuous processing.
