Energy Saving and Carbon Reduction

以製造業思維管理能源效率

FEDS has adopted a “manufacturing mindset for service industry energy efficiency” approach since 2015. The energy management team established energy performance indicators (KPIs) and conducts regular monthly reviews and analysis of various energy consumption data. Through a dual approach of “software management and hardware maintenance,” FEDS continues to enhance energy usage efficiency and improve energy management performance.

Establishment of KPIs for Regular Monitoring

In 2024, the Engineering Department established 13 KPIs related to energy efficiency and equipment maintenance management. Compared to the previous year’s indicators, the changes are as follows: 6 indicators have been retained, 5 indicators have been revised, 2 new indicators have been added, and 1 indicator has been removed, all aimed at implementing energy management actions. FEDS holds monthly energy meetings to improve energy efficiency and establish a better energy management model.

Introducing ISO Standards to Improve Management

FEDS has introduced the ISO 50001 Energy Management System at its corporate headquarters, Banqiao Store and Tainan Store. In 2024, the implementation procedures of the “Energy Management Action Plan” were updated at the site, completing the “Energy Risk Opportunity Identification Form.” Currently, changes in external and internal issues, as well as risks and opportunities related to the energy management system, have been included in the assessment. Significant risks identified from the assessment are used to establish and control energy objectives, serving as the basis for the 2024 energy goals and targets.

Promoting Energy-Saving Projects

The Engineering Department continued to promote various energy management and energy-saving improvement projects including off-peak control for elevators, and installing variable frequency automatic deceleration devices on escalators. Additionally, FEDS continued to evaluate the replacement of old chiller units and the implementation of the iAuto Smart Control Platform to manage the air conditioning system. iAuto automatically adjusts the operation frequency of chiller pumps and cooling tower fans to achieve optimal energy-saving control and enhance energy efficiency.

Air Conditioning Energy Conservation

  • Reduced operating hours for high energy-consuming air conditioning units in some retail areas.
  • Controlled cooling tower water outlet temperature during non-summer periods.
  • Installed magnetic levitation centrifugal chilled water host units.
  • Added frequency inverters to air conditioning units.
  • Enhanced air conditioning heat dissipation efficiency.
  • Regularly monitored chilled water host unit operating efficiency.
  • Performed regular cleaning of air conditioning system filters and cooling towers.
  • Modified cooling towers to external air wet bulb control.
  • Added timer control for wastewater aeration systems.

    • Lighting Energy Conservation

  • Continuously replacing with new energy-efficient lighting fixtures.
  • Using motion sensor lighting in parking areas.
  • Dynamically adjusting lighting brightness based on weather conditions.

    • Elevator Energy Conservation

  • Installing variable frequency control for escalators.
  • Switching passenger elevator operating modes during off-peak hours.
  • Installing automatic on/off devices for elevator interior lighting and ventilation fans.
  • Controlling elevator machine room cooling ventilation fans with temperature control switches.

    • Note 1: FEDS XinYi A13 and the Zhubei Store were included in the electricity statistics starting 2021 and 2022, respectively.
    • Note 2: Xinyi A13 was added in 2021,FEDS Zhubei was added in 2022, and Baoqing Store was closed in 2024.
    • Note 3: Due to the pandemic impact, all branches shortened operating hours from May to July 2021, resulting in significantly reduced electricity consumption.

    FEDS consumed 0.0036 kWh for every NT$1 of revenue generated in 2024, a reduction of 18% compared to 2017, indicating a gradual decrease in energy dependency. In 2024, FEDS set a target of reducing electricity consumption by 1%. The total electricity consumption, including self-generated green energy, was 214.958 million kWh, a decrease of 8.021 million kWh compared to 2023, achieving an energy-saving rate of 3.6%, surpassing the established goal. In terms of the relationship between revenue and electricity consumption.

    Towards the target of net zero emissions by 2050 and in line with the government’s energy transition policy, FEDS launched its green energy initiatives early. Two branches – Top City Taichung (opened in 2011) and FEDS Xinyi A13 (opened in 2019) – have installed solar power generation systems with a combined capacity of 96 kW. To expand green energy usage, FEDS launched the ‘Green Power Plan’ in 2022 in cooperation with Farglory Energy Co., Ltd. In 2024, solar power generation equipment was completed at Hualien Store with a generation capacity of 817 kW. The combined capacity of the three solar power generation systems totals 913 kW, representing a 9.5-fold increase from the previous year, with an estimated annual production of 1 million kWh of green electricity.

    • Note: Green electricity data (self-generated and self-consumed) includes statistics from FEDS Xinyi A13 and Top City Taichung Store, with Hualien Store added in December 2024.

    Greenhouse Gas Inventory

    In 2019, FEDS took Hualien Store as a demonstration store and introduced ISO 14064-1:2018 carbon emission inventory. Through the standardization process to identify the Company’s internal energy consumption and carbon emissions, FEDS further control bulk energy consumption and carbon emission projects. In 2022, the coverage rate of greenhouse gas inventory fully expanded to 100%. Using the operation control method, 100% of the greenhouse gas emissions caused by the facilities managed or operated by the company was recognized for inventory. 

    Following an investigation, FEDS’ greenhouse gas emissions in 2024, including Scope 1 and Scope 2, totaled 73,312 metric tons, a decrease of 5.5% compared to the previous year. The carbon intensity was 1.24 metric tons per million New Taiwan Dollars.

    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 0.507 kg CO2e/kWh.
    • Note 2: Emission intensity = Total carbon emissions (ton) ÷ revenue (NT$100 million)
