Meidensha Corporation (Meiden) and one of its subsidiaries, MEIDEN KOHSAN
CO.LTD., have received the 2022 Environment Minister’s Commendation for GlobalWarming Prevention Activity. The minister’s recognition was for introducing activitybased working*1 (ABW) and Meiden’s multi-functional power conditioning system*2(PCS) at MEIDEN KOHSAN’s new head office building in Tokyo’s Shinagawa Ward.
Meiden has also received the same commendation for developing and commercializing
an Ecotank Type Vacuum Circuit Breaker (VCB) that does not use sulfur hexafluoride(SF6), a greenhouse gas – the first time in the world for this type of product.
The commendation given to Meiden and the subsidiary is in the category of “pioneeringintroduction and proactive implementation.” The commendation given to Meiden alone
is in the category of “product development and commercialization.” Sponsored by theEnvironment Ministry, this commendation gives public recognition to individuals andentities that have made outstanding achievements in alleviating climate change andadapting to climate change.
The Meiden Group is the only corporate group to have received the 2022
commendation in these two categories.

Optimal allocation of windows to allow natural light into the office and use ofLED light bulbs to drastically save energyIntroduction of multi-functional PCS developed by Meiden, which is used as astorage battery for power generated with solar panels; for charging anddischarging power by EVs; and as a power source used at the new headoffice.

Certified as being the highest rank in the Building-Housing Energy-efficiency
Labeling System (BELS), as well as ZEB Ready*3 as defined by the Ministry ofEconomy, Trade and Industry.

Use of carbon dioxide-free electricity generated by M Winds Co., Ltd., aMeiden group company, thereby emitting no CO2 in Scope 1 and 2 andreducing annual CO2 emissions by about 49 tons.

Outlines of activities

No use of SF6 gas in order to make it smaller, lighter and economical. In 2020,Meiden says it developed and marketed 145kV Ecotype VCB for the first timein the world.

Reduction of greenhouse gas emissions by about 82 percent in the entire
lifecycle of the product compared with those by gas circuit breakers, byreplacing SF6 gas with compressed dry air and using non-magnetic aluminumfor the tank to drastically reduce conduction loss.
