Executive Officer
In Charge of Living Environment & Digital Media Equipment Group

The Living Environment & Digital Media Equipment Group focuses on the air conditioning and refrigeration systems business, one of Mitsubishi Electric's growth drivers. In addition to expanding operations in the room and package air conditioner segment, we are pressing forward with the creation of new businesses and strengthening existing ones.

As we expand our businesses, it is important for us to contribute to our customers' initiatives to reduce negative environmental impact through energy conservation, recycling and the utilization of renewable energy. As part of this, we are supplying a broad range of environmentally-friendly products and services for the home, office, and industry. These include air conditioners that reduce CO2 from product use and our energy-saving EcoCute product lineup. We also offer photovoltaic systems that generate renewable energy and do not produce CO2 during power generation. Additionally, Mitsubishi Electric proposes solutions that aim to achieve energy savings by systems as a whole, in support of programs such as ZEH and ZEB promoted by the Japanese government.

Meanwhile, as activities to reduce CO2 from production, the Living Environment & Digital Media Equipment Group is proactively introducing its core energy-saving products—namely, high-efficiency air conditioners, heat-pump hot-water supply systems, LED lighting fixtures, and photovoltaic systems—at production sites. We are also promoting energy-saving activities by improving productivity linked to just-in-time improvement activities based on e-F@ctory concepts.
