Using insulation to reduce energy use

The company reduced the air-conditioning cooling load by installing insulation around the exhaust ports of the reflow system and dryer to block heat conduction. This reduced energy use by 4,651 Kwh per year.

Surface temperature decreased from 44.2°C to 21.9°C.

Introducing buses to reduce CO2 emissions

The company has 40 buses that it provides for employees to use for their daily commute. Around 2,100 employees use these commuting buses. This measure accounts for an annual reduction of CO2 emissions of 1,600 kg.

Installing a unique solar system

Casio (Thailand) has installed its own photovoltaic system to take advantage of the tropical sunlight. Electric power generated by the solar panels is used to power electric roof fans to draw heat out of buildings, as well as for powering daytime lighting in a warehouse and agitating a reservoir for oxygenation.

Introducing the latest energy-saving air-conditioning systems

A new watch plant that started operations in May 2018 uses the latest energy-saving air-conditioning systems, such as an air-conditioning system with several air-conditioners with FFUs*1 and ceiling cassettes, zoning and separate air-conditioning for clean rooms. These systems enable efficient operation according to the production situation.

*1 FFU: Fan-filter unit. A system that passes air sucked in by the fan through a filter to purify it before sending it out as clean air.

│Initiatives at Casio America

Casio America has been carrying out energy-saving measures for many years. In five years (2011, 2012, 2013, 2017, and 2018) it was recognized under the International ENERGY STAR Program.*1 Casio America has also signed a contract with a retail electric power provider for 100% green electricity.

Going forward, Casio America will continue to carry out environmentally friendly initiatives to help achieve a sustainable society.

*1 The International ENERGY STAR Program is an international energy conservation scheme for office equipment (ENERGY STAR). The U.S. Environmental Protection Agency (EPA) has set product power consumption and other standards, and products that meet these standards are allowed to use the International ENERGY STAR logo.

│Initiatives at Hachioji R&D Center

The Hachioji R&D Center has installed automatic blinds and grows a green wall of vegetation at its facility to reduce CO2 emissions. The automatic blinds calculate the location of the sun, use sensors to detect the strength of the sunlight, and open and close automatically, thereby reducing the cooling and heating load. Since 2012, the Center has also grown a green wall of vegetation as a summertime energy-saving measure in an effort to reduce the cooling load even more. Through a process of trial and error to balance watering, fertilization, and sunlight, currently, the green wall (planted with two kinds of morning glories) grew splendidly to a size of 8.5 meters wide by 10 meters tall. Local residents even stopped by to take photos of it. This initiative to grow a green wall of vegetation has entered Hachioji’s Green Wall of Vegetation Contest in the “organization grouping” since 2017 and won awards two years running, including the first place award in 2017.

│Installation of LED Lighting

Casio is installing LED lighting at its business sites to reduce electricity consumption. Thus far, it has installed LED lighting at many Casio sites, including the Hatsudai Head Office, Hamura R&D Center, Hachioji R&D Center, Yamagata Casio, Casio Electronics (Shenzhen) Co., Ltd., Casio (Thailand) Co., Ltd., Casio America, Inc., and Casio Electronics (Shaoguan) Co., Ltd., and other sites. The installed LED lighting has brought about substantial CO2 emissions reductions.
