SDG7.2.2 Upgrade buildings to higher energy efficiency
1. NCUE holds an annual energy-saving and carbon-reduction meeting to evaluate plans for the replacement of existing equipment with energy-saving equivalents the following year. At least NT$5 million is invested annually to replace energy-consuming equipment, which is forecasted to achieve the goal of increasing total energy efficiency by at least 1% per year (the goal is to save 150,000 kWh or more annually).
1.1 NCUE has implemented a range of major energy conservation and carbon reduction measures from 2019 to 2022.
1.2 In response to the national policy of promoting renewable energy, NCUE installed solar power cells on the roof of the Jinde campus gymnasium in 2017. The capacity of the generator is 467.28 kWp and it is expected to generate 625,945 kWh of power annually. The event was highlighted in the regional Changhua news (for details of the news report, please refer to http://epage.ncue.edu.tw/files/14-1000-13227,r9-1.php)
The above picture shows the gymnasium’s roof with installed solar cells.
2. In response to the national policy, NCUE plans to complete the second installation of photovoltaic solar cells on the roofs of other school buildings by the end of 2022. The total capacity of the solar power system on the Jinde campus is expected to be 2,085.75 Kw, and that on the Baoshan campus is expected to be 571.5 kW. In addition to reducing the net energy load of the buildings, in certain scenarios (such as off-peak months), the buildings’ energy needs can be entirely met by the solar power system. By reducing the amount of energy drawn from the main grid, local line loss can be reduced by approximately 3%, improving energy efficiency. Moreover, solar panels block direct sunlight that would otherwise be absorbed by the roof. According to research, direct sunlight on the roof can be reduced by 38% with the use of solar panels and roof temperature, consequently, can be reduced by 2.8 °C. Thus, the temperature inside the buildings can be lowered, use of air conditioners can be reduced, and energy efficiency can be improved.
3. The (partial) design and layout of the rooftop photovoltaic solar cells on each building in the Jinde and Baoshan campuses from 2021 to 2022 are as follows:
