2 emissions per total floor area in FY 2023 (37,821 t-CO2) in-ased by 25.3% from the previous year. This was due, in part, to approximately 1.4 times in the CO2 emission coeffi cient (a value icating CO2 emissions per kWh of electricity supply) of the main ctricity supplier (from 0.000311 to 0.000434 t-CO2/kWh) for elec-ity consumption, which accounts for approximately 78.9% of the iversity’s energy consumption.00000000（1,000 kWh)(1,000m3)FY 2019FY 2020FY 2021Total (1,000 kWh)Consumption rate (kWh/m2)（kWh/ｍ2）Total (1,000 mm3）（m３/ｍ2）Consumption rate （m3/m2 ）Total（kL ）Consumption rate（Ｌ/ｍ2 ）0.0050.0040.0030.0020.0010.000FY 2022FY 202375,00071,673 70,230 67,716 65,000132.3 129.6 55,000123.1 45,000FY 2019FY 2020FY 20214,3007.65 7.24 4,1004,146 7.11 3,9003,909 3,920 3,7003,500FY 2019FY 2020FY 2021（kL）1.51.20.90.810 0.60.638 0.00150 0.385 0.30.00070 0.00118 0.014570,313 69,841 135128.2 128.2 125115FY 2022FY 20238.07.06.71 6.56 6.03,681 5.03,573 4.0FY 2022FY 2023（Ｌ/ｍ2）1.294 0.00238 0.600 0.00109 The basic unit of electricity consumption in FY 2023 remained unchanged compared to the previous fi scal year but decreased by 3.0% compared to FY 2019, prior to the COVID-19 pandemic.The basic unit of city gas consumption in FY2023 decreased by 2.3% compared to the previous fiscal year and decreased by 14.3% compared to FY 2019, prior to the COVID-19 pandemic.The basic unit of fuel oil consumption in FY 2023 increased by 118.2% per unit compared to the previous year and increased by 58.6% compared to FY 2019, prior to the COVID-19 pandemic.FY 2023, energy consumption from electricity, gas, and heavy oil aled approximately 765,000 gigajoules (*1). Energy consump-n decreased by 10.1% compared to FY 2022, and the energy nsumption per unit area (calculated by dividing the energy con-mption by the total fl oor area of all buildings) also decreased by % compared to FY 2022 and by 14.1% per unit area compared the pre-pandemic level in FY 2019. believe one of the factors was changing the air conditioning stem from gas to electric. We will continue to promote energy nservation.
