    1. Reporting Policy

    Scope of calculations Calculations cover Tokyu Construction Co., Ltd. and its Seven consolidated subsidiaries inside and outside Japan*1, 2. However, data for which the scope of calculation differs is annotated individually.
    Reporting period Each fiscal year covers the one year period from April 1 to March 31 of the following year.
    Third-Party Assurance The environmental performance data for fiscal year 2023 marked with have received limited assurance from Ernst & Young ShinNihon LLC.
    Notation of figures in tables Figures in tables are rounded to the nearest whole number

    1：(Subsidiaries in Japan) Token Industry Co., Ltd., Tokyu Renewal Co., Ltd., Kawamura Sekisan CO., LTD., (Subsidiaries outside Japan) PT. TOKYU CONSTRUCTION INDONESIA,GOLDEN TOKYU CONSTRUCTION CO., LTD.,TC Pacific Construction, LLC,INDOCHINE ENGINEERING LIMITED

    2：Figures for subsidiaries in FY2018 have been estimated by multiplying Tokyu Construction’s unconsolidated results by the net sales ratio. From FY2019 onwards, with some exceptions, calculations have been based on actual results at subsidiaries.
    FY2022, calculations were based on the actual performance values of all subsidiaries.

    Reduction in Energy Required by Products and Services Sold During the Period

    For fiscal year 2023, the reduction in required energy was calculated as the difference between the designed primary energy consumption (Et) and the standard primary energy consumption (Est) for buildings (17 cases) designed and constructed by our company. The difference (Est − Et) represents the energy reduction.
    For details, please refer to the explanation of “Standards (base year, reference values, etc.) used in calculating energy consumption reductions, and the theoretical basis for the selection of these standards.”

    13：Overall energy consumption is estimated by multiplying the energy consumption per value of finished work at the sampled worksite by the value of finished work for the aggregation period. Energy consumption is estimated by subtracting the reductions brought about by energy-saving operations from this amount.

    14：City gas: calorific conversion factor 44.20 MJ/Nm3, LPG: 50.08 MJ/kg, Oils; Heavy oil A (in Japan): 38.90 MJ/L, light oil (in Japan): 38.04 MJ/L, kerosene (in Japan): 36.49 MJ/L, gasoline (in Japan): 33.36 MJ/L, RD(in Japan): 34.40MJ/L, BDF100: 35.60MJ/L

    15：GTL is calculated using an emissions intensity of 2.396 t-CO2/kl, a figure based on data registered on the CO2 emissions of GTL when used as an alternative fuel to diesel fuel (8.5% less than diesel fuel) in the New Technology Information System (NETIS) database of the Ministry of Land, Infrastructure, Transport and Tourism (reg. No. KT-190065-A).
    - RD (Renewable Diesel): Fuel produced from waste cooking oil, non-edible oil, etc. Calculated using an emission intensity of 0.000 t-CO2/kL
    - BDF100 (Bio Diesel Fuel): Biofuel for diesel engines produced by methyl esterification of rapeseed oil, waste cooking oil, etc. “100” is not blended with petrodiesel and uses 100% BDF. Calculated using an emission intensity of 0.000 t-CO2/kL

    16：Renewable energy includes the purchase of renewable energy, the purchase of renewable energy certificates, and the self-generation and consumption of renewable energy.

    Standards Used for Calculating Energy Consumption Reductions (Base Year, base Values, etc.) and Theoretical Basis for Standard Selection

    Based on the building energy consumption performance standards specified in the "Act on the Improvement of Energy Consumption Performance of Buildings" (standards defined by the Ministry of Economy, Trade and Industry and the Ministry of Land, Infrastructure, Transport and Tourism for the structure and equipment of buildings necessary to ensure energy consumption performance, BEI), the design primary energy consumption (Et) derived from design specifications and the standard primary energy consumption (Est) derived from standard specifications are determined. The difference (Est − Et) is used to calculate the reduction in required energy.
    For the calculation of the Building Energy Index (BEI) under the building energy consumption performance standards, there are two methods: the Standard Input Method and the Model Building Method. In the Standard Input Method, both the design primary energy consumption (Et) and the standard primary energy consumption (Est) are calculated and established, and the BEI (Et/Est) is derived. On the other hand, the Model Building Method only calculates and establishes the BEI using a calculation program (Model Building Method Input Support Tool, developed by the Building Research Institute), and Et and Est are not separately calculated or established.
    Due to differences in the data (BEI, Est, Et) calculated and established by the Standard Input Method and the Model Building Method, the calculation methods for energy reduction have been differentiated as follows:
    Calculation method I The reduction in required energy is calculated based on the design primary energy consumption (Et) and the standard primary energy consumption (Est) obtained from the Standard Input Method.
    Calculation method II Est and Et are calculated from the BEI obtained using the Model Building Method. To calculate the standard primary energy consumption (Est), the total floor area is multiplied by the energy consumption intensity for each building use (source: "Digest of the Report on Building Energy Consumption Survey 43," p. 6, June 2021, published by The Building-Energy Manager's Association of Japan, based on the 2019 energy consumption survey). This value (Est) is then multiplied by the BEI to calculate and establish the design primary energy consumption (Et).
