The traditional lamps are replaced by LED lamps year by year. From 2018 to 2022, a total of 8,807 LED lamps have been replaced, and 80% of the school has been replaced.
-
The campus elevators adopt frequency conversion type energy-saving elevators, all of which are equipped with electric energy recovery devices, and the electricity saving rate is about 22%.
-
The whole school fully (100%) uses high-efficiency (CSPF/EER) or inverter air-conditioning.
-
The new chilled water host will be completed in December 2022 with variable frequency stepless air-conditioning control, and the annual electricity saving benefit is estimated to be about 1.07 million yuan.
-
The student dormitory area will fully (100%) use heat pump devices to provide hot water in 2021, replacing boilers that burn heavy oil.
-
The first phase of the green energy solar photovoltaic power generation equipment project (the roof of the activity center) will be completed in August 2022, with an estimated annual power generation of 614,426 kWh.
-
The addition of electronic water meters in each building will be put into use in September 2022. In the future, water consumption data will be provided for reference in energy-saving analysis.
