Energy Management Strategy and Governance 

The Office of General Affairs leads CSU’s low-carbon campus initiatives, creating energy-efficient, resource-conscious, healthy, and eco-friendly facilities. From 2023 to 2025, CSU invested NT$51 million in government-supported energy-efficiency projects.

Under the University’s Energy Conservation Management Guidelines, CSU sets short-, medium-, and long-term targets and promotes energy-labeled procurement, energy efficiency, and environmental education.

Using 2018 as the baseline year, CSU targets a 1% annual reduction in energy use intensity (EUI). in 2025, electricity consumption decreased by 5.96%, demonstrating continued progress in energy conservation and carbon reduction.

Energy Management 

◎ Energy Consumption Profile and Challenges 

Average campus floor area per student is 26.41 m² for daytime programs and 33.23 m² for continuing education programs. Given the intensive use of campus space and concentrated energy demand from teaching, research, air-conditioning, and lighting, CSU monitors its electricity profile and energy-intensive equipment while adopting efficient technologies and smart management to reduce energy use and emissions.

◎ Energy-Saving Strategies and Targets 

Guided by equipment efficiency, smart management, and behavioral change, CSU implements its Energy Conservation Management Guidelines and integrates smart monitoring, data analysis, and energy management to improve campus energy efficiency and advance toward a smart, net-zero campus.

As air-conditioning and elevator systems are the University’s major electricity consumers, CSU prioritizes high-energy equipment upgrades, optimized energy management, and behavioral change through short-, medium-, and long-term initiatives.

Energy-Saving Strategies 

Short-, Medium-, and Long-Term Energy-Saving Targets 

◎ Smart Energy Governance and Digital Transformation 

In 2025, CSU upgraded its Energy Management System (EMS), integrating campus electricity data with real-time monitoring, analytics, and anomaly alerts. Future AI-enabled monitoring will optimize energy-intensive equipment, reduce energy use and emissions, and advance a smart, net-zero campus.

Energy-Saving Measures and Results 

CSU combines hardware upgrades with smart management to improve energy efficiency and build a low-carbon campus.

1. Green Infrastructure: in 2025, CSU installed 10 smart meters, integrated five chiller units into the EMS, equipped 137 classrooms with smart air-conditioning controls, and installed 24 smart streetlight control units.

2. Digital and Behavioral Management: Lighting controls, card-activated air-conditioning, submeters, and electricity monitoring support demand control and energy conservation.

◎ Energy-Saving Measures Implemented in 2025 

Energy Performance

In 2025, CSU consumed 56,875.4190 GJ of energy and purchased 14.440841 million kWh of electricity, down 0.98% year-on-year. Adjusted electricity consumption indicates stable energy efficiency.

Note: (1) Purchased electricity: 1 kWh = 0.0036 GJ. Heating values: gasoline 7,520 kcal/L, diesel 8,629 kcal/L, natural gas 5,925 kcal/m³, and LPG 5,958 kcal/L, based on the Bureau of Energy’s Heating Values of Energy Products; 1 kcal = 0.000004184 GJ. (2) Energy Use Intensity (EUI) = annual electricity consumption ÷ gross floor area (kWh/m²·year). (3) Cumulative electricity savings = (2018 baseline consumption − current-year consumption) ÷ 2018 baseline consumption × 100%. 

Trend of Purchased Electricity (Unit: mWh) 

Renewable Energy Installations 

Supporting Taiwan’s renewable energy policy, CSU leases rooftop space to a professional solar provider. Solar PV systems have been installed on eight buildings, including the Library and Technology Building, College of Management Building, and Student Activity Center, reaching 761.46 kW of installed capacity in 2025.

The electricity generated is sold to Taiwan Power Company, expanding renewable energy supply. CSU’s renewable energy share reached 7.48% in 2025 and is targeted to reach 10% by 2033 through further solar installations, supporting the energy transition and low-carbon campus development.

Renewable Energy Utilization Rate

Water Resource Management 

◎ Water Risk and Use Profile 

CSU primarily uses freshwater for daily activities, landscape irrigation, and laboratories. the WRI Aqueduct Water Risk Atlas classifies the campus as a low-to-medium water-risk area.

Since completing campus-wide sewer connection works in 2016, all building wastewater has been discharged through the public sewer system in compliance with water quality standards.

CSU adopts a dual approach of source reduction and end-of-pipe treatment, supported by water recycling and reuse. in 2025, water consumption decreased by 9.82% from 2024.

◎ Water Management Challenges 

Water demand has increased following the opening of the international dormitory, new teaching facilities, and professional training spaces. CSU continues to install water-saving equipment, optimize water management, and promote conservation, focusing on reducing per-capita consumption and improving water-use efficiency.

▲ Student Visit to the Chengcing Lake High-Quality Water Environmental Education Park

◎ Water-Saving Performance 

In 2025, CSU withdrew 131,352 tonnes of water, down 10,548 tonnes (7.43%) from the 2020 baseline of 141,900 tonnes and 9.82% from 2024. Despite increased demand following the conversion of the Hsing-Hsueh and Yu-Tsai Buildings into international dormitories, total water withdrawal continued to decline, demonstrating the effectiveness of water-saving measures. Per-capita water use was 22.44 L/day, below the 70 L/day average for national universities and colleges of science and technology.

Per-Capita Water Use and Water-Saving Rate 

Note: (1) Per-capita water use = total water consumption × 1,000 liters ÷ 365 days ÷ total number of students, faculty, and staff. (2) Water-saving rate = (previous-year consumption − current-year consumption) ÷ previous-year consumption.

Annual Water Consumption Trends

Green Building Materials 

CSU follows Taiwan’s Green Building Label standards, covering biodiversity, greenery, site water retention, energy and water conservation, carbon and waste reduction, environmental quality, wastewater treatment, and waste management.

Green-certified materials and design elements are incorporated into all new construction and building renovations.

Green Transportation and Low-Carbon Commuting 

CSU promotes public transit, shared bicycles, and ride-sharing to reduce commuting emissions. the University operates electric scooters and reserves EV charging facilities in new construction projects.

As a high-density urban campus with limited space for large-scale cycling, CSU improves green mobility through integrated transport and circulation planning.

CSU joined the YouBike Low-Carbon Cycling Initiative in May 2025, encouraging cycling for short commutes and campus travel. by year-end, participants had reduced emissions by 318.7 kg CO₂e, demonstrating collective action toward sustainable mobility.
