SDG 7.4.4
SDG 7.4.4 Policy development for clean energy technology
1. In line with government regulations and standards on environmental protection, energy conservation, and water conservation, NCUE uses clean energy and improves the efficiency of its existing energy use through the following measures:
(1) All new buildings obtain Green Building Label certification as required by law.
(2) In line with the latest environmental regulations, NCUE purchases only Tier 1 inverter air conditioners with CSPF (efficiency > 5.1 kWh/kWh) and implements automated shutdown timers.
(3) LED energy-saving lamps (efficiency > 100 lm/W) are to be installed when constructing new buildings and during the refurbishment of old buildings.
(4) NCUE installs only energy-saving amorphous-core power transformers, whose core loss is 80% lower than that of conventional iron-core transformers.
(5) NCUE selects IE3 or higher high-efficiency motors and equips high-power or frequently used motors with soft starters or variable-frequency drives.
(6) Lighting in public areas has been upgraded with motion-sensor controls or timers.
(7) Alongside the construction of a megawatt-scale energy storage system, NCUE performs peak-shaving and valley-filling power dispatch, which helps stabilize the national power grid and improves the efficiency and stability of the campus power supply.
(8) The heating systems, such as boilers or heat pumps, have their water temperature reduced from 50°C to 45°C during summer to avoid unnecessary energy waste.
(9) To reduce electricity consumption by water dispensers, only the ground floor water dispensers in each building (excluding dormitory areas) are set to provide cold water.
(10) Accessible elevators are equipped with power regenerative devices to optimize energy efficiency.
(11) To implement an effective energy management system, improve energy savings, and reduce energy costs, NCUE has fitted all air conditioners in the Baisha Building with temperature monitoring, load-shedding, and shutdown control functions (as shown in Figure 1). The system integrates demand control to regulate peak electricity use and keep peak loads within the contracted capacity. NCUE plans to extend the system to all campus buildings.

(12) NCUE installed smart meters throughout the campus and added an energy management system (EMS), completing campus-wide deployment by the end of 2025 to strengthen energy management. The system tracks the power supply zones and high-consumption loads of each building, visualizes electricity use, and issues alerts when demand exceeds the contracted capacity. NCUE expects the system to raise energy efficiency by more than 10%.
(13) In April 2026, NCUE replaced the 100RT chiller and the air handling units on B1 to 4F of the Main Library, which will improve equipment performance and electricity use every year.
(14) By September 2026, NCUE will downsize the transformers at the Main Library, the outdoor courts, Student Dorm 3, and Student Dorm 7 and replace them with amorphous-core transformers to save energy, cut carbon emissions, and lower electricity costs.
(15) In 2026, Taiwan Power Company (Taipower) and NCUE signed the "University Energy Conservation and Power Resilience Project," under which Taipower is subsidizing NT$100 million in construction funding for NCUE. The funding is primarily allocated to building a smart microgrid at the Shida Campus, which includes the addition of a 1.8MWh energy storage battery, 378.25kWp of solar power, six vehicle slow-charging stations and one fast-charging station, as well as the replacement of aging transformers, the installation of soundproof diesel generators, and the implementation of a hierarchical energy management system — the "Campus Microgrid Smart Energy Management System (NCUE MG EMS)" (as shown in Figure 4). This will strengthen the campus's islanding power resilience to at least four hours during power outages, and achieve energy conservation, carbon reduction, and electricity cost optimization goals through peak shaving and valley filling.
NCUE is also one of the key demonstration sites of Taipower's University Microgrid Demonstration Project. To advance energy technology innovation, the practical application of microgrids, and talent development, Taipower selected demonstration schools from universities with electrical engineering departments nationwide. Only six universities have been selected in this initial phase to serve as test sites for verifying and developing energy technologies. Figures 5–6 show the related news coverage.

3. By building a megawatt-scale energy storage system and installing rooftop PV systems on every building, NCUE advances the development of energy-saving technologies and the use of clean energy. These facilities also enable NCUE to serve as a green energy demonstration school for the national government and to share its experience, helping the government formulate clean energy and energy-saving technology policies.
(1) NCUE's existing 1 MW/1.26 MWh energy storage system, 100 kW/50 kWh energy storage systems, 30 kW/78 kWh electric bus V2G/G2V charging station, and a combined 2,688.75 kW of PV capacity on Shida and Jinde Campuses serve as a real-world site and demonstration system for smart green energy microgrids.
(2) NCUE conducted the National Science and Technology Council (NSTC) project "Research and Demonstration of Multiple Microgrids in a High-Proportion Photovoltaic Solar Environment," establishing a microgrid demonstration system integrating renewable energy, energy storage systems, V2G/G2V, and demand response. This practical demonstration system serves as a valuable reference and support for the development of related technical policies.
4. NCUE has also actively supported the government's energy policy initiatives. In 2025, NCUE carried out multiple energy-related research projects for the National Atomic Research Institute, the National Science and Technology Council (NSTC), and other agencies, as shown in Table 2. In addition, NCUE professors have served as committee members, such as on the "MOEA's Electric Reliability Review Committee" (Figure 14) and the "Green Factory Label Clean Production Technology Review Committee" (Figure 15).
