Activities to Reduce Environmental Impacts

Energy consumption reduction

To prevent resource depletion and global warming, it is essential to reduce consumption of electricity, gas and petroleum, which contributes to carbon dioxide emissions. Fujitsu Laboratories carries out distinct energy-saving activities at each of the three Areas.

The chart shown below gives the annual changes in energy consumption (CO₂-t) at Fujitsu Laboratories since 2000.

• Activities in 2006
  
  • Infrastructure plant and equipment investment
    In the Atsugi Area, We updated the kerosene use absorption refrigerator in a high efficiency turbo refrigerator
• Main efforts to save energy
  
  • Room lightings are turned off during lunchtime and in areas where illumination is unnecessary, Personal computers are set to energy-saving mode. Use of elevators is discouraged.(three areas)
  • A card reader system was installed for each air-conditioner so that the air-conditioner can be started and stopped only when a card is inserted and removed. As a result, users can turn on air-conditioners only when needed, and this can prevent air-conditioners from running unnecessarily.(Atsugi Area)
  • A system was installed for precise control of the numbers of running turbo coolers and water cooler/heater units, all of which are electrical equipment in heating, ventilation, and air-conditioning systems, based on current loads. This system helps save the energy required for air-conditioning.(Atsugi Area)
  • Each department sets themes for energy-saving campaigns. All staff participate in these campaigns.(Atsugi Area)
  • Introduction of inverter air-conditioning of a building(Kawasaki Area)
  • As an energy saving tool, We installed an electricity monitor in every main breaker of the power pro-experiment and was able to grasp use electric energy every room, a history every time of the electricity. （Kawasaki Area）
