Reduction in Energy Usage
Basic Approach
With the aim of "reducing the basic unit of energy consumption by an annual average of 1% based on FY2013, and achieving at least 7.73% reduction in FY2021, compared with FY2013", we have created various measures for energy conservation at all plants and business sites in Japan.
Promotion of Energy Conservation
Energy Conservation Target and Progress
Energy conservation target: To reduce the basic unit of energy consumption by an annual average of 1%, from FY2013 to FY2021.
• Changes in the basic unit of energy consumption
In FY2018, energy conservation measures lead to the significant improvement of energy consumption per unit. These measures include the installation of LED lighting, the review of the equipment control value, and the operation of production equipment, according to increased production of toner.
Energy Conservation Efforts
Energy Conservation Efforts
At each plant and business site in Japan, we have improved the efficiency of air-conditioning equipment by taking measures, such as switching to high-efficiency air conditioners and cleaning the fins of its outdoor units. In addition, we implemented various measures for saving electricity consumption, such as efficient operation of production facilities by reviewing their operating conditions and the reduction of their operation time by improving production yield. As for lighting equipment, we introduced approximately 10,000 LED lights through March 2018.
LED lightning will be gradually introduced in the future.
Efforts to Reduce Peak Electricity
Since 2011, at each plant and business site in Japan, we have worked to reduce peak electricity during the summer. In FY2018, we conducted various measures for saving electricity consumption, such as reducing unnecessary lighting and eliminating the operation of certain elevators.
Main measures for electricity consumption in Japan
- Implement "Cool Biz" and "Warm Biz" *
*"Cool Biz" and "Warm Biz" are Japanese campaigns initiated by the Japanese Ministry of the Environment as a means to help reduce electricity consumption in the office by limiting the use of air conditioning. By changing the standard office air conditioner temperature to 28℃ in summer and to 19℃ in winter and by introducing a liberal summer or winter dress code, staff can work in the warmer or cooler temperature. - Upgrade from desktop PCs to laptop PCs
- Temporary shutdown of air conditioning and total heat exchangers
- Installation of heat shielding film and blinds on skylights and veranda glass
- Reduction of unnecessary lighting and review of the amount of office equipment in operation
- Reduction of electricity consumption for air conditioning by using electric fans
- Shut down certain elevators, except when employees enter or leave the office
- Sharing of cooler spaces by changing the floor layout
- Implementation of operating equipment by using demand monitoring system*
*Demand monitoring system : System measuring maximum demand electrical power continuously 24 hours a day and alerting when it nearly exceeds the set target value
