Reduction of Greenhouse Gasses

Example Initiative CITIZEN YUBARI

“Kitaguni Energy Saving and New Energy Grand Prize” Awarded

In November 2014, CITIZEN YUBARI was awarded the “Kitaguni Energy Saving and New Energy Grand Prize”, run by the Hokkaido Bureau of Economy, Trade, and Industry.
The “Displacement Ventilation System with Outdoor Air Cooling” introduced with the cooperationof local Hokkaido University efficiently discharges heat exhaust and pollutants created by indoor manufacturing equipment, ensuring a good work environment while also making possible high-level energy-saving conversions through features such as reduction of air movement power, usage of heat exhaust, and an outdoor air cooling system that uses cold air outside. Annual energy consumption was reduced by about 64% at the new factory that introduced this system.

Conversion of Lighting to LED

At CITIZEN Group, the entire group hasactively moved forward with conversion of interior office lighting to LED both in Japan and overseas as part of our energy-saving activities.
For example, at leisure service provider CITIZEN PLAZA, we exchanged the ice rink’s roof lighting with lights mounting CITIZEN ELECTRONIC’sLED package. LED lighting reducednot only energy consumption by half compared tothe previous mercury lamps, but also energy amounts consumedby freezing equipment used to cool the ice because it does not produce heat. With the brighter rink, we have received very positive feedbackfrom customers.

Initiatives toward Environmentally friendly Services withSolution Businesses

At CITIZEN MACHINERY, to improve services for customers, we have set up four solution centers in Japan. Previously, to observe receiving inspections of NC automatic lathes or to check test cuts, customers needed to come to our headquarters in Karuizawa or the Kitakami works, costing time and money for the customer and increasing CO2 emissions in proportion to the distance. In order to solve these issues, we have established remote observation system by using a high-definition videoconferencing deviceat the nearest solution center. Also, by deploying a variety of services withthese high-definition videoconferencing device, such as specification and technology discussions as well as satellite training sessions held simultaneously at multiple sites. We continue towork to simultaneously realize service improvements as well as CO2 emissions reductions.
A service we have beenworking to realize in recent years is named “alkartoperation,” which conducts maintenance at distant locations by remotely controlling customers’ machines. Utilizing the internet to gather a variety of information from the machines, the service quickly restores customers’ machines after failures and improves their productivity throughprecise remote operation handled by engineers.
Also, a teleconferencing system called “alkartjoint” can be simultaneously used to communicate with customers during the mentioned operations. With these services, we can support our customers’ innovative monozukuri efforts while also contributing to customers’ environmentally friendly activities withfewer business trips ofservice personnel, conservation of electricity through work improvements, and more.


Energy-saving Activities

Electricity usage control panel (installed October 2016)

(Every day, the amount of electricity used at the time of the check, the previous day, and each month areshown to each division.)
Note: currently, the biggest consumptionof electricityare made by the heat processingat the press factory, followed by compressors, then by air conditioners.
In 2017, wework to make improvements in these three categories.
