Total reduction in ten years
|
Amount of money of reduction（D-A+E-B）＝ ９,８５５,０００yen reduction
|
| Amount of CO2 reduction（F-C） ＝ １１７tons reduction |
If it is our company LED lighting, the deletion of 4 million 92.8 thousand yen (E-B)
and amount of of CO2 exhaust about 117 tons can be expected as about
4 million 92.8 thousand yen (D-A) and frozen load 100% in ten years in the electricity bill.
|
※1 It is longevity when lighting for ten hours a day.
※2 The electricity cost unit price is calculated with 1 15 yen/KWh.
※3 The frozen load assumes power consumption to be 100%. The load goes
up by the temperature in the warehouse low.
※4 The carbon dioxide exhaust coefficient is calculated based on exhaust
coefficient (0.357kg/kwh) of NEDO.
※ A basic charge of the electric power can be reduced by the energy-saving effect.
