Tokyu Construction Co., Ltd. announced on the 11th that it will calculate all carbon dioxide (CO2) emissions related to its own buildings and provide them to the desired customers in a single sheet. For new construction work to be ordered in the future. Annual CO2 emissions generated in a series of processes such as material procurement, building construction, and operation after completion are estimated in a short time by an original method and listed in graphs and numerical values. See the results and review the proposals to help reduce CO2.
CO2 emissions of buildings including the supply chain are related to construction materials such as steel frames and concrete ▽ Fuel for heavy machinery and transportation vehicles, construction related to temporary electricity, etc. ▽ Operation related to buildings such as electricity and fuel used after completion- It is roughly divided into three.
Material-related emissions are calculated based on the "stacked CO2 emission calculation sheet" created by the company through public data and interviews with manufacturers. Emissions during construction are calculated by coefficienting the construction record data owned by the company. Emissions after completion are calculated by assuming general energy consumption for each application and combining with the energy saving performance index (BEI) at the time of design.
In recent years, due to growing interest in climate change, companies are required to understand the total CO2 emissions of buildings, including the supply network. By combining Tokyu Construction into a single sheet, it will be possible to show customers the expected emissions in an easy-to-understand manner. Once the quantity of required materials is decided, the trial calculation results can be obtained in a short time, and it will lead to the proposal of a plan that can further reduce CO2 and construct efficiently.
In the future, we will contribute to the realization of a carbon-free society while making proposals that meet customer needs, such as balancing costs.
