1. Factory facilities
Hitachi Construction Machinery Tierra installed amorphous transformers, which have considerable energy-saving benefits, as energy consumption in standby mode is roughly one-third to one-sixth less in comparison with conventional silicon steel transformers. Hitachi Construction Machinery Tierra also updated its ventilation systems to gas heat pumps, which have little energy waste, and offer higher energy efficiency than electricity.
2. Manufactured products
In accordance with Hitachi’s proprietary Design for Environment (DfE) Assessment standards, Hitachi Construction Machinery Tierra develop and supply energy-efficient products that have a reduced environmental impact throughout the product lifecycle.
3. Employee commuting
Recognized under the Excellent Eco-Commuting Business Site Certification System for its employee eco-commuting activities *2
