5.2.9

(3) Measure
- The batteries of concerned 144 units were replaced, and a test was done on shutting of the power source.
  The test confirmed that both “startup time” and “startup quality” were good.
- It was standardized that the backup batteries should be replaced periodically.
  Thereafter, the operation system was established and “shutting off of the power source supplying power to unused manufacturing facilities” was implemented, and thereby the standby electric power was reduced.

6. Effects of energy conservation efforts
Total: 1,583 thousand kWh (annual electric power saving)
[1] Compressor system: 616 thousand kWh
(1) Reduction in no-load operation: 155 thousand kWh (requiring set point adjustment only without capital investment)
(2) Installation of a high-efficiency compressor: 461 thousand kWh (payout period of the investment, 2.5 years)

[2] Core facility system: 676 thousand kWh
(1) Energy conservation of vacuum pumps: 219 thousand kWh (use of stocked items, without capital investment)
(2) Energy conservation concerning the cooling and heating water pumps: 298 thousand kWh (payout period of the investment, 0.7 years)
(3) Energy conservation for air conditioning: 159 thousand kWh (payout period of the investment, 0.2 years)

[3] Manufacturing machine system: 291 thousand kWh
(1) 291 thousand kWh (investment: cost of batteries only amounting only to several tens of thousand yen)

[3] Visualization
Briefing sessions were held on developments and achievements of measures on a case-by-case basis. In addition, information was “visualized” by publishing on LAN and posting on the bulletin board on corridor walls, so that anyone can understand the progress.

[4] On-site investigation, management manual, and standards of judgment
When improving/reviewing management manual based on on-site investigations, it is necessary to deeply understand and enforce of “Standards of Judgment”. Collection and analysis of data by “measurement and record” and “stopping when unnecessary”, etc. were extremely useful. In addition, by taking an on-site investigation, awareness of “Energy Conservation Act” was even raised and deployment of activities of this case was enabled.
