Clean Factories - Factory Energy Conservation

Panasonic Shikoku Electronics Co., Ltd., which produces switching power supplies and non-shrinking high density package substrates in the Ozu district, established a three-year energy conservation plan. The company also reviews its energy map (a record of the amount of electricity used by equipment and the time of usage) and formulates a new equipment plan on an annual basis.
   As a result of reducing the number of clean rooms and thereby the number of air conditioners used, and by reducing the amount of air used for ventilation by lessening the load for rooms kept at a constant temperature, it became possible for the company to manage its facilities in response to changes in operational status. In this way it was able to reduce its energy use per basic unit by 15% over three years. In recognition of these practical energy conservation efforts, the company received a prize from the Director-General of the Agency for Natural Resources and Energy as one of the factories commended for their excellent energy use in fiscal 2007.
