Reducing Electricity Usage

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
