Offices

All Casio office sites are engaged in efforts to reduce CO2 emissions and cut resource use by upgrading office equipment and improving work processes.

Reducing power consumption through server integration

Casio has vastly reduced its energy consumption by integrating the servers that had once been disparately located across the group.

Server integration results

A total of 1,080 servers had been integrated by March 2016.

Effects of reducing power consumption through server integration

This server integration effort resulted in a total reduction in power consumption of 1,620,000 kWh, yielding a reduction in CO2 emissions of 588 tons.

Initiatives at Casio America

Casio America has been carrying out various environmental initiatives over many years. These include sorted collection of bottles and cans, collecting and taking out used paper and cardboard for recycling, using recycled materials for individual watch packaging and display stands, replacing old energy-inefficient personal computers, and providing employees with reusable drink bottles to reduce the need for paper cups.
These activities have been recognized by the Morris County Municipal Utilities Authority (MCMUA), which promotes environmental protection by presenting awards to companies for their green endeavors.

Casio Europe's energy-efficient building

Casio's office sites have shifted from focusing on reducing CO2 per unit of production to cutting the total volume of CO2 emitted across the entire Casio Group. In January 2009, Casio Europe integrated its offices, distribution center, and service center, which had previously been separately located around Germany, into a new energy-efficient building.

This building has an innovative air conditioning system that uses Geothermal heat collecting equipment 130m below ground to pump water through pipes embedded in the concrete ceiling and floor of the building. The system pumps cool water in the summer and hot water in the winter to either cool or heat the building.
Energy consumption in the building is further reduced by controlling room temperatures using blinds that open and close automatically according to the weather as well as proper ventilation.

Hachioji R&D Center takes on the challenge of climate change and environmental preservation

The Hachioji R&D Center was designed and constructed to reduce CO2 emissions in order to contribute to the fight against climate change. The center continues to take on the challenge of environment protection. Some of its innovations are highlighted below.

Ongoing power-saving activities

The Hachioji R&D Center completed in November 2003 is a research and development facility that incorporated environmentally friendly equipment from the initial design stage. It has been running efficiently for approximately 12 years since it opened, boasting energy-saving features such as high-efficiency vertical thermal storage tanks, a natural ventilation system, automatic blinds, lighting control and equipment control based on weather forecasting. Thus, instead of just relying on its hardware, the center has been enthusiastically pursuing other improvements such as finely tuned temperature control adjustments, and the revision of operation methods based on actual daily data. In fiscal 2013, interior lighting fixtures started being converted from fluorescent to LED, as part of effort to reduce energy consumption.

Natural ventilation system maximizes use of outside weather conditions

No heating equipment is needed at the Hachioji R&D Center. This is because the building has comprehensive thermal insulation, which prevents interior heat from escaping to improve thermal efficiency. Since room temperatures increase even in winter, due to body heat and heat from equipment such as computers, the interior is cooled by letting outside air in as needed through ducts on each floor. This provides ventilation through natural airflow using the chimney effect to lower room temperatures. Thus, the temperature is adjusted using hardly any electric power.

Automatic blinds and a green wall of vegetation

Automatic blinds reduce the air conditioning load by calculating the position of the sun and using sensors to detect its intensity to open and close automatically. The center has been using these blinds, combined with a green wall of vegetation, since 2012 in an initiative to reduce the cooling load in the summer. The center has also reduced unnecessary usage of electricity by regulating air conditioning to match the number of people in the building according to building entry data and by switching interior lighting on and off and adjusting brightness with sensors that detect room brightness and human movement.

The initiatives of the Hachioji R&D Center make a significant contribution to reducing CO2 and energy conservation. They also play a further role in environmental education via descriptions given during facility tours for elementary and junior high school students from the local area and beyond and others who visit the Hachioji R&D Center.

Installation of LED lighting

Through the active adoption of LED technology within the Casio Group, energy consumption for lighting has been greatly reduced. As of March 2016, about 4,200 LED fixtures have been installed, saving about 87 tons of CO2 emissions per year compared to conventional fluorescent lamps.

Participation in Light Down Campaign

Casio supports COOL CHOICE, the Japanese government’s national campaign, and the Fun to Share climate change campaign being implemented by the Ministry of the Environment. Casio once again took part in Light Down campaign in 2015. Three companies, Casio Computer Co., Ltd. (five sites including the company headquarters, Hamura R&D Center, and Hachioji R&D Center), Yamagata Casio, and Casio Electronics Manufacturing, took part in the campaign.
