Past Activities

Headquarters

Goal

Reduce yearly electricity consumption by 1.2% by 2012
(against the year 2008 consumption level)

This target will be achieved by an improved air conditioning controller and the use of energy-saving LED lighting.

Total electricity consumption (2008): 1,727,000kwh

Current reduction ratio [January to September 2011] :
-1.04% (adjusted to per-year basis)

Actual electricity usage reduction:

2010 8,400kwh
2011 (Jan. to Sept.) 13,500kwh

Tochigi Plant

Goal

Reduce yearly electricity consumption by 1.2% by 2012 (against the year 2008 consumption level)

This target will be achieved by an improved air conditioning controller, more power-efficient melting furnace heater and the use of energy-saving LED lighting.

Total electricity consumption (2008): 24,062,000kwh

Result
