A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

Regularly cleaning the air conditioners’ filters plays an important role in lowering energy consumption. From 2019, every department in the university was asked to carry out the energy saving plan and make sure the air conditioners are energy-efficient. In 2020, the university started to check if the AC filter was cleaned regularly. The department which doesn’t follow the energy saving plan will be fined.


A brief description of energy use standards and controls employed by the institution:

Our campus has constructed digital electricity meters in every department in recent years. Gradually, setting up surveillance in the campus' electricity and control system is eco-friendly to provide each unit or department with the electricity control. Every year, each educational department has undertaken management on monitoring the allocation of electricity and the allocation of targeted electricity, and then sent the date and manifestation of the electricity usage to each management unit for corresponding buildings by the Office of General Affairs. By doing this, we are able to fortify management of usage and improve energy efficiency.


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

The university replaced the old lighting lamps with energy-efficient lighting from 2016 via the ESCO project. There are about 36,000 old lamps and lanterns being replaced. The annual energy saving benefit can reach more than 3 million degrees.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

Continuously, our campus has been conducting the setups of solar photovoltaic energy systems and mass sale operations. Before 2020, we have finished this in Motorcycle Parking Tower(83.2 kWp), Swimming pool(263.52kWp)、Alumni Gymnasium(175.68kWp), University Administration(98.82kWp)、Macronix Building(29.28kWp)、Shui Mu Student Center(43.92kWp) and Feng Yun Building(29.28kWp) and so on. Awarded with “Honorable Mention” of a national university in “the total capacity of the setup of roof-shape solar photovoltaic energy system” by the Ministry of Education.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

From 2019, we actively seeked the “supplement project in replacement of eco-friendly apparatus” from the Department of Housing of Hsinchu City Government, and the “application to refunding cargo tax from the Ministry of Finance” to set up the electricity meter in Tsing Hua lab, the non-windpipe ventilator system, and air-conditioner equipment. In 2019 and 2020, respectively, we had taken at least 1.5 million NTD financial infusions. In 2021, projecting to undertake relevant application work in addition, we expect within 5 years the 5000 old non-conversion air conditioner in campus would be replaced.
