Energy resource management

YunTech has constructed a sustainable green campus, actively improved energy-saving facilities and equipment, and built a comprehensive campus power monitoring and energy-saving management system in response to the government’s renewable energy plan to create a green, energy-saving, and low-carbon environment. The school has also used the idle roof space of the school buildings to promote energy conservation, effectively activate the school assets, provide heat insulation and cooling effect on the top floor, and rent out the roof platform of the school’s North Campus to manufacturers to build solar photovoltaic power generation systems. The installation capacity of the first phase was 495.88 kWp, the installation capacity of the second phase was 698.27kWp, and the total installation capacity reached 1,194.15kWp. Installing photovoltaics on the school building’s roof can effectively utilize the roof’s idle space, provide fixed income, and provide heat insulation and cooling to the top floor. The system can assist in reducing the power consumed by air conditioners in the building and achieving the vision of energy security, a green economy, and environmental sustainability.

In 2021, the school’s total electricity consumption was 16,559,024 kWh (including solar power generation for self-use). The smart cloud management system monitored the school’s electricity consumption status in real-time. It decreased by 910,468 kWh compared to 2020, and the power saving rate was 5.21%.

Smart Campus

The smart campus plan was proposed to improve the daily safety of teachers and students in the school, build a high-quality learning/research environment, and achieve a sustainable and innovative smart campus. The goal was to construct the “Energy Resource Management System,” “Safety Monitoring System,” “Health and Comfort Management System,” and “Smart Traffic Management System” to construct energy conservation, carbon reduction, comfort and convenience, and sustainable campuses. This plan was gradually implemented over 4 years (from 2016 to 2019). In 2021, it was modified according to needs and functions to better serve the school’s needs.

Classroom Courses & Smart Energy Conservation

Automatic classroom power supply smart power-saving system (general classroom): The project was completed in 2019. The smart energy-saving system for the general classroom automatically controls air-conditioning and provides power according to the current power-saving status and power distribution of each building. It is also integrated with the classroom power management system to control the power supply. The system is used for air conditioning in 167 classrooms, and lighting and fan power supply in 28 classrooms are also connected to this system. In 2021, the system software stability was maintained and improved.

Smart Control of Small Air Conditioners

Energy-saving management and control for small air conditioners (non-classroom areas): the plan was completed in 2019: The daily operation schedule, external air temperature, and contract capacity unloading requirements are used to schedule and unload 1,534 smallscale air conditioners to perform energy-saving management and monitoring. We also maintained and improved the system software’s stability in terms of time scheduling and round-robin unloading in 2021.
