In order to carry out continuous improvement in environmental performance, Hitachi Construction Machinery Group constructed its own aggregation system which visualizes our companies’ environmental footprint. Since 2014, four environmental impacts ((1) energy and CO2, (2) waste, (3) water, and (4) volatile organic compounds (VOC)) have been managed monthly, switching from management in three-month cycles. This has made it possible to build a PDCA cycle corresponding to monthly performance variations and has been hugely successful in improving performance.
In the five plants in Ibaraki Prefecture, we have introduced the integrated energy & equipment management service “EMilia*1” utilizing advanced IoT technology from Hitachi, Ltd. to engage in initiatives such as power saving in production facilities and saving electricity in offices to lower peak electricity usage and reduce standby power consumption based on visualized data of power consumption and standby power usage. Such efforts received recognition in the form of the FY2018 “Prize of the Chairman of ECCJ” awarded by The Energy Conservation Center, Japan.
Since April 2021, we have been using “Hitachi Construction Machinery Energy Control System” to continuously reduce energy consumption at production bases.
