Energy Conservation and Environment Protection
The achievements and implementation measures of energy management policies formulated by TBB are outlined in the following chapter:
- The Bank has implemented water-saving and power-saving measures since 2010 in line with the government’s energy conservation and carbon reduction policies with significant energy-saving results. To save more electricity and due to the recent impact of the COVID-19 pandemic on the domestic economy, TBB is actively responding to the government’s policy on economic stimulation, and has expanded capital expenditures to replace energy-consuming equipment at various locations. During 2019 to 2021, more than 100 high-efficiency air conditioners, air-conditioning units, and cooling towers were installed at business units. It is estimated that the around 10% of the power can be saved after the replacement. This has demonstrated that TBB supports domestic enterprises and the green energy industry through actions.
- In 2021, TBB completed the second bank-wide office lighting replacement project, through which LED lamps certified with the latest Energy-saving Mark were adopted. More than 29,000 lamps were replaced, which greatly reduced the power consumption from lighting at business premises. Each year, the entire bank saves around 1.717 million kWh of electricity and reduces carbon dioxide emissions by 862 metric tons, contributing to energy conservation, carbon reduction, and environmental protection. (based on our country’s electricity carbon emission coefficient of 0.502kg CO2e/kWh in 2020)
- TBB promotes the informatization of electricity consumption at energy-consuming locations, and has installed digital meters at 15 business premises, including the head office, Chongnan Building, Linkou Server Room, and Songshan Branch, to control electricity consumption so as to reduce electricity costs.
- The head office building has adopted the iEN energy management system to continue to monitor the air-conditioning, lighting, and power system of the entire building. We learn about the energy usage efficiency of the entire building through data analyses and continue to uncover the potential for energy conservation. The implementation of this project has increased energy conservation rate by more than 37.2%. Compared to the total electricity consumption in kWh in the year which was used as the baseline, we saved approximately 377,000 kWh of electricity (equivalent to 1.357MJ) in 2021. We reduced carbon emissions by 189 tons and saved approximately NT$1.13 million in electricity costs each year.
- In the event of equipment anomaly in the energy management system of the head office, the computer actively sends an SMS and email to notify personnel to take immediate actions and effectively reduce equipment damage and the impact of the disaster. Variable frequency air-conditioning units can save substantial amounts of electricity in summer. Coupled with the use of LED lights, we have reduced the contract capacity of the building for 2 consecutive periods and the head office building is no longer considered a major energy user (lower than 750kW) with significant results in energy conservation. In 2021, the replacement of 8 elevators in the Head Office have been outsourced, which will be upgraded to energy-storage elevators successively to further improve energy saving.
- In recent years, the Bank has been striving for energy conservation. Besides Chu Pei Branch which won the Excellence Award (first prize) in the Commercial Building Group in the “Service Industry Excellent Power Conservation Award Program” organized by Hsinchu County Government, the Head Office building of the Bank also won the recommendation award of Industry and Commerce Group B of the “Leadership Award for Energy Conservation” of Taipei City Government in 2021, reaffirming the Bank’s efforts in continuously implementing energy conservation and carbon reduction and promoting the sustainable environment.
- TBB actively participate in energy conservation promotion and education. We post energy-saving posters and energy-saving slogans in various business places, cooperate with policies to promote energy-saving, promote energy-saving deeds at the branches, and share the energy conservation experience of each unit and a collection of energy-saving promotion activities in our internal quarterly publication. The head office prepared a manual for air-conditioning equipment panels to allow our fellow colleagues to understand how to set the air-conditioning temperature at 26˚C and to adjust outdoor lighting and advertising lights in line with the sunrise, sunset, and each season. During the planning of renovation projects or the procurement of business equipment, we pay attention to energy efficiency and participate in energy-saving seminars and observation activities outside the Bank.
TBB started conducting ISO14064-1 greenhouse gas inventory and obtaining third party certification since 2018. Early inventories from 2018 to 2020 covered the head office building. To monitor carbon emissions across the entire bank, the scope of inventory was extended to cover all domestic locations, and overseas branches and subsidiaries from 2022.
Short - term:1% carbon reducing across the bank in 2023 compared to 2022.
Medium-term:3% carbon reducing across the bank in 2026 compared to the base-year(2020).
Long-term:5% carbon reducing across the bank in 2031 compared to the base-year(2020).

Note:
- The ratio of change in the past year is based on the difference between electricity consumption in kWh in 2021 and 2020 divided by the electricity consumption in kWh in 2020.
- In March 2021, TBB has installed a 120-ton air-conditioning main unit with frequency conversion and double helix at the Chongnan Building, which is expected to reduce electricity consumption by more than 10% every year.

Note:
- The emission factor refers to greenhouse gas equivalent = activity data × emission factor × global warming potential. Purchased electricity: calculated using the 2020 electricity carbon emission factor of 0.502kg CO2e/kWh announced by the Bureau of Energy. Refrigerant (including chillers, refrigerators, drinking fountains, etc.): greenhouse gas equivalent = original volume × dissipation factor × global warming potential. The equipment dissipation factor is derived from the 2006 IPCC Guidelines for National Greenhouse Gas Inventories, volume 3, chapter 7, table 7.9. The median value was adopted as the dissipation factor.
- The greenhouse gas emission factor for gasoline (official vehicles), diesel (emergency generators), and natural gas (employee cafeterias) was calculated based on the Greenhouse Gas Emission Factor Management Table (Version 6.0.4) of the Environmental Protection Administration, Executive Yuan.
- The global warming potential (GWP) was based on the GWP value in the 4th Assessment Report of the IPCC (2007) in which CO2=1, CH4=25, N2O=298, SF6=22,800, and HFCs are determined based on the type.

- TBB formulates budgets each year and prioritizes the purchase of products that meet energy conservation marks or similar levels of efficiency for water and electricity use and other equipment. We shall replace old air-conditioning and water usage equipment with new ones that have higher efficiency. TBB requires all units to record the quantity and cost of electricity and water used in each period, and compare them with the same period of the previous year to immediately respond to anomalies. In the renovation of TBB’s premises, we adopt water-saving products such as water dispenser, water-saving toilets and water-saving gaskets installed on faucets, and in conducting the faucet renewal project of the head office, automatic sensor faucets were adopted instead. After the equipment is improved, the water consumption is reduced by 50%, and the per capita water consumption is reduced from 23.39 (cubic meter/person-year) to 21.92 (cubic meter/person-year). Dedicated personnel and maintenance manufacturers would regularly inspect or maintain water equipment, so as to reduce the cleaning frequency of official vehicles.
