SDG7.2.4 Plan to reduce energy consumption

NCUE has implemented the regular replacement of old, energy-consuming, and low energy-efficient equipment based on the requirements of each building, to achieve the goal of saving 1% total energy annually. From 2007 to 2020, NCUE has reduced its annual power consumption by more than 15%. The power saving plan for 2019-2022 is presented in the table below.

Year	Measures
2022	Install a peak offloading system for air-conditioning, prioritizing systems based on year and region, until the entire University is covered. It is expected that the system will reduce annual power consumption by 100,000 kWh. Replace the T5 lights of all buildings with LED lights, which involves at least 500 light replacements. This measure is expected to save more than 50,000 kWh of power annually. Implement the routine replacement of all air-conditioning units with more energy-efficient units, which involves more than 70 replacements and is expected to save 100,000 kWh of power annually.
2021	Replace the 300RT water-cooled chiller and ancillary equipment in the gymnasium of Jinde campus, which is expected to save 227,603 kWh of power annually. Replace the T5 lights of all buildings with LED lights, which involves at least 500 replacements and is expected save more than 50,000 kWh of power annually. Implement the routine replacement of air-conditioning units, which involves more than 50 replacements and is expected to save 75,000 kWh of power annually.
2020	Replace the water-cooled chiller and ancillary equipment in the Library and Information Center Building of Jinde campus, which is expected to save 327,603 kWh of power annually. Replace the T5 lights in the classrooms on the first floor of the gymnasium with LED lights, to save 25,028 kWh of power annually. Replace 64 air-conditioning units, saving approximately 1,500 x 64 = 96,000 kWh of power annually.
2019	Replace the T5 lights on the first and second floors of the library with LED lights to save 27,430 kWh of power annually. Replace 64 air-conditioning units to save approximately 97,500 kWh of power annually. Calibrate the equipment in the machine room of the swimming pool to sleep during closed periods to reduce annual power consumption by up to 40,000 kWh.

Timers or sensors are used to manage the automatic activation of electrical equipment, which ensures proper illumination while saving energy.

The picture above shows the trend of power consumption from 2007 to 2021.

The Baoshan campus uses a large-scale energy storage system to shift power consumption from peak hours to off-peak hours. In 2021, the highest peak-hour power consumption reduction reached 43% (because of the COVID-19 pandemic, the power consumption in 2021 was lower than usual; hence, the reduction was higher than that of previous years). The measure helped reduce the loss of high-voltage lines and improve efficiency of energy transmission. In addition to complementing the power supply with a photovoltaic solar system during peak hours, NCUE also uses large-scale energy storage systems to reduce peak demand and improve energy efficiency.
