Energy Management
Chang Gung University continues to improve energy efficiency and develop a low-carbon campus through energy-efficient equipment upgrades, optimized energy use, and renewable energy installations. These efforts progressively reduce the University's dependence on purchased energy and support its transition toward sustainability.
Key Achievements
Our Approach
Energy-Efficient Equipment Upgrades
Upgrading LED lighting, air-conditioning systems, and elevator equipment to reduce campus energy consumption.
Systematic Energy Management
Establishing electricity monitoring and energy-saving target management mechanisms to continuously improve energy efficiency.
Renewable Energy Development
Developing solar photovoltaic systems in phases to reduce the University's dependence on purchased electricity.
Renewable Energy Development
Chang Gung University is developing its solar photovoltaic systems in phases. In 2025, Phase I generated 602,304 kWh of electricity. Phase II was completed on March 31, 2025, and generated 347,585 kWh, operating under a self-generation and self-consumption model to effectively reduce dependence on purchased electricity.
Annual solar electricity generation in 2025, contributing to the University's renewable energy development.
Operating under a self-generation and self-consumption model to reduce dependence on purchased electricity.
CGU will continue to expand renewable energy development and plan energy storage systems to enhance campus energy self-sufficiency.
Energy Management Mechanism
Continuous Energy Performance Improvement
CGU uses annual total electricity consumption and Energy Use Intensity (EUI) as its primary monitoring indicators. Through equipment improvements and management mechanisms, the University continuously optimizes energy efficiency and maintains a dynamic energy-saving improvement process.
Campus Energy Use Intensity
Energy Use Intensity (EUI) reflects electricity efficiency per unit of campus floor area. EUI continued to decline in 2025 compared with the previous year, indicating that the University's energy-saving measures are gradually producing results.
