Environmental Preservation

Energy Conservation

 The Alps Group carries out energy conservation activities as a countermeasure to global warming under its 8th Medium-Term Action Plan for Environmental Preservation. Our target is to reduce energy consumption per unit by an average 1% annually up to 2020 from base year fiscal 2012.
 This target applies to the Alps Group as a whole and each of the Alps Electric, Alpine and Alps Logistics Groups plans and implements measures matching their particular business formats in order to attain it.
 In fiscal 2016, Alps Electric achieved energy savings by upgrading to high-efficiency facilities and also sought to conserve energy through operational improvements like improving the energy efficiency of production facilities, optimizing operation of utilities, and remedying air leaks from compressed air systems. A 24.8% reduction in energy consumption per unit (unit of output, compared to the base year) was achieved.
 Further efforts will be made in fiscal 2017 to rationalize energy use centering on introduction of high-efficiency facilities and operational improvements, the two primary approaches to energy conservation.

Energy Consumption (Crude Oil Equivalent)

*1 Energy consumption (crude oil equivalent): Electricity, fuel and other energy consumption
*2 Per unit of output: Energy consumption divided by output value

Energy Consumption (Crude Oil Equivalent)
CO2 Emission

* Per unit of output: CO2 emissions divided by output value

Saving Energy by Changing Vacuum Pump Operation Methods

Saving Energy by Changing Vacuum Pump Operation Methods

 Nagaoka Plant has achieved enormous energy savings after reviewing methods for operating vacuum pumps ancillary to manufacturing equipment. Before, the pumps were left to run continuously, but now they are made to run only when required after confirming the details of manufacturing processes. Energy savings of around 92% were achieved as a result.

 

Saving Energy Through Improvements to Server Room Air Conditioning

Saving Energy Through Improvements to Server Room Air Conditioning

 The Alps Headquarters building has reduced energy consumption (power consumption for air conditioning) of its server room by 15.3% through measures including insulation of the raised floor, installation of wind direction panels, reduction of the amount of circulating air (40% decrease) and a change to the air conditioning temperature setting (24°C → 28°C).
 The measures also helped improve inconsistencies in temperature and air flow volume in cold aisles (aisles with cold flowing air).
