Energy Saving and Carbon Reduction


Due to the extended operating hours from 10 to 11 hours for FEDS’s various branches, energy management has become a crucial management issue. To achieve maximum energy saving and carbon reduction, FEDS adopts a “manufacturing mindset for managing energy efficiency in the service industry”. Since 2015, the Engineering Department has been at the core of this approach, setting energy key performance indicators (KPIs) and conducting monthly reviews and analysis of various energy consumption data. At the same time, they enhance the maintenance and repair of equipment. By employing a dual approach of “software management and hardware maintenance”, the Company continuously improves energy efficiency and enhances energy management performance.

Establishment of KPIs for regular monitoring

In 2022, the Engineering Department established a total of 12 KPIs in areas such as energy efficiency and equipment maintenance. Dedicated personnel track and analyze these indicators’ data on a monthly basis. They assist branches with poor KPI performance in identifying the reasons and developing improvement plans. For branches with excellent performance, they are invited to share their practices during management meetings. Through mutual exchange, discussion, and learning, we will inspire more solutions to optimize electricity measures, establish a better energy management model, enhance energy efficiency and enable continuous improvement.

Introducing ISO standards to improve management

FEDS took the lead in the industry in introducing the “ISO 50001 Energy Management System” in the corporate headquarters building and Mega City Banqiao Store in 2017. In 2018, it further established the “Real-time Energy Performance Indicator Platform” in Mega City Banqiao Store, becoming the first department store in Taiwan to introduce this system. In 2021, the Tainan Store was selected to introduce the “ISO 50001 Energy Management System”. In the future, it is planned to introduce the “ISO 50001 Energy Management System” in the three flagship stores, including Top City Taichung Store, the Zhubei Store, and FEDS XinYi A13. In 2022, each introduced site continued to pass various renewal evaluations and verifications.

Promoting energy-saving projects

FEDS carried out 24 energy-saving projects in 2022, with a total investment of NT$24,418 thousand and a total energy-saving benefit of 1,638,001 kWh. Among them, 6 energy-saving projects are multi-year implementation plans, and the rest are plans that can be completed in the current year. In terms of energy-saving measures, there are 7 energy-saving improvement plans related to the water chiller units, and the energy-saving benefits can reach 789,118 kWh; there are 12 energy-saving improvement plans related to lighting, and the power-saving benefits can reach 569,245 kWh. Through the improvement of the water chiller units and lighting equipment, the energy-saving benefits generated by both accounted for 83% of the total energy-saving benefits.

Excellent performance in energy efficiency

The annual energy usage intensity per unit area (EUI) is one of the important energy management indicators for FEDS. Our management target refers to the average EUI of the department store industry, and the EUI is tracked and managed by the engineering department on a weekly basis. Looking at the actual EUI figures, we can see that FEDS’s dependence on energy has decreased year by year, and the EUI decreased from 333 in 2017 to 314 in 2022, showing a decrease of 6%. From the perspective of the relationship between turnover and electricity consumption, the electricity consumption per NT$1 of turnover of FEDS has dropped from 0.00441 kWh in 2017 to 0.00397 kWh in 2022, a decline of 12%, which indicates that the energy-saving management measures promoted by FEDS are taking effects, evidenced by the significant improvement in energy efficiency. In the next five years, FEDS aims to reduce electricity consumption by 15% for every NT$1 of turnover.

  • Note 1: FEDS XinYi A13 and the Zhubei Store were included in the electricity statistics starting 2021 and 2022, respectively.
  • Note 2: Affected by the epidemic, each branch has shorten its business hours from May to July 2021, resulting in a significant reduction in electricity consumption.
FEDS aims to save 1% of electricity per year. In 2022, the total electricity consumption of the 12 stores in Taiwan was 226.19 million kWh, an increase of 23% compared with 2021. The increase in electricity consumption was mainly due to the expansion of operating locations with the addition of the Zhubei Store. In addition, due to the influence of the epidemic from May to July 2021, the department store industry has shortened business hours, resulting in a reduction in electricity consumption. Therefore, after removing the factors such as the epidemic, business hours, and new store openings, the electricity consumption of 11 stores (excluding the Zhubei store) was 192.49 million kWh, a decrease of 11.38 million kWh or 6% compared with 203.87 million kWh in 2020, and the energy efficiency was continuously optimized.
In line with the government’s energy transition policy, FEDS has launched its green energy layout in advance, and the two branches, namely Top City Taichung Store opened in 2011, and FEDS XinYi A13 opened in 2019, have installed solar power generation systems with a total capacity of power generation of 96 kW. In order to increase the use of green energy and reduce greenhouse gas emissions, FEDS launched the “Green Power Plan” in 2022. In cooperation with Prime EcoPower Co., Ltd., FEDS Group’s affiliated company, it is planned to add two new solar power generation facilities in the Hualien Store and FEDS’s own land in Taitung, with a power generation capacity of nearly 1,600 kW. It is estimated that after completion in 2024, they will be able to produce 1.14 million kWh of green power per year for self-use.
  • Note: The statistics of solar power generation were from Top City Taichung Store, and FEDS XinYi A13 was added starting 2021.

Greenhouse gas inventory

In 2019, FEDS took the Hualien Store as a model store to introduce ISO 14064-1: 2018 carbon emission inventory, and identify the Company’s internal energy consumption and carbon emissions through a standardized process in order to further control the bulk energy consumption and carbon emission items. In 2022, the scope of greenhouse gas inventory was fully expanded to the head office and 12 operating sites in Taiwan, and the operation control method was adopted to recognize 100% of the greenhouse gas emissions caused by the facilities under the management or operation control of the Company.

Carbon dioxide emission intensity

  • Note 1: The carbon emissions are calculated based on the electricity carbon emission coefficient announced by the Bureau of Energy. The 2022 coefficient has not been released, and hence the calculation was based on the 2021 coefficient of 0.509 kg CO2e/kWh.
  • Note 2: Emission intensity = Total carbon emissions (ton) ÷ revenue (NT$100 million)
