Chung Yuan Christian University has established and continues to implement an energy efficiency plan to reduce total energy consumption.<\/p>\n\n\n\n

    \n
  1. Policy and governance:<\/strong>\n
      \n
    1. ISO 50001 Energy Management System (EnMS) adopted in September 2022, together with an Energy Policy Declaration.<\/li>\n\n\n\n
    2. Energy Saving and Carbon Reduction Committee chaired by a Vice President; the Environmental Safety Center leads implementation and auditing.<\/li>\n\n\n\n
    3. Each unit appoints an energy management officer, and an internal audit system is in place.<\/li>\n<\/ol>\n<\/li>\n\n\n\n
    4. Annual energy-saving action plans:<\/strong>\n
        \n
      1. Prepared each year under ISO 50001, with 3, 3 and 4 approved actions in 2023, 2024 and 2025 respectively.<\/li>\n\n\n\n
      2. Electricity saved: approx. 113,400 kWh (2023), 243,702 kWh (2024) and 246,942 kWh (2025).<\/li>\n<\/ol>\n<\/li>\n\n\n\n
      3. Air-conditioning efficiency:<\/strong>\n
          \n
        1. Old chillers and chiller systems replaced: 3 units (2023), 7 (2024), 4 (2025); air-handling units replaced: 108, 125 and 184 units.<\/li>\n\n\n\n
        2. Air-cooled chillers upgraded to water-cooled systems, with efficiency gains of 30% or more.<\/li>\n\n\n\n
        3. Variable-frequency drives and cooling-tower descaling devices added, bringing a further efficiency gain of 10% or more.<\/li>\n\n\n\n
        4. Cooling towers (100 RT and above) with descaling devices increased from 8 (2023) to 12 (2025), targeting 18 by 2028 and 20 by 2029.<\/li>\n<\/ol>\n<\/li>\n\n\n\n
        5. Lighting efficiency:<\/strong>\n
            \n
          1. LED replacement building by building since 2019, with 26,289 luminaires replaced to date.<\/li>\n\n\n\n
          2. Indoor LED share rose from 86% (2023) to 94% (2025), targeting 99% by 2027 and 100% by 2028.<\/li>\n\n\n\n
          3. Outdoor walkway lighting fully converted to LED in 2024; stairwell lighting is being converted to motion sensors or automatic blinking devices.<\/li>\n<\/ol>\n<\/li>\n\n\n\n
          4. Smart metering and monitoring:<\/strong>\n
              \n
            1. Smart electricity meters increased from 805 (2023) to 1,058 (2025\u20132026), targeting 1,196 by 2027.<\/li>\n\n\n\n
            2. Common classroom air-conditioning and teaching-building lighting are connected to the energy management system with automatic scheduling.<\/li>\n\n\n\n
            3. 149 laboratories and research spaces will be added to electricity monitoring and air-conditioning management by 2027.<\/li>\n<\/ol>\n<\/li>\n\n\n\n
            4. Renewable energy:<\/strong>\n
                \n
              1. Solar PV installed: 10.08 kWp (self-use), 180.46 kWp (self-generated, sold to the grid) and 1,510 kWp (leased-roof installation), with a further 350 kWp under construction.<\/li>\n\n\n\n
              2. Expansion targets: 701.5 kWp by 2028, 807 kWp by 2030 and 1,838 kWp by 2049.<\/li>\n<\/ol>\n<\/li>\n\n\n\n
              3. Results:<\/strong>\n
                  \n
                1. Energy Use Intensity (EUI) fell from 104.2 to 82.79 kWh\/m\u00b2\/yr, a 20.5% reduction over ten years.<\/li>\n\n\n\n
                2. Average annual electricity saving rate of 2.22% over 2015\u20132024, exceeding the government standard of 1%.<\/li>\n\n\n\n
                3. Total energy consumption decreased from 21,171,736 million calories (2023) to 21,049,316 million calories (2025).<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
