METI / ECCJ / ACE Training Program MTPEC05 (2006.08)

6-2. For industrial sector

Public Programs on Energy Conservation Auditing Performed by ECCJ

We have made public the proposed measures & expected effects for other factories' reference.

1-day Energy audit (Factory/Building) for energy conservation

Type of audit: Management audit and Utility audit (mainly)

Management (organization, target, standard, operation-manual, maintenance, measurement, record, etc.)
loss (heat, steam, electricity—compressed air etc., idling time, shut-down time, etc.)
Efficiency (energy unit consumption, 1-loss/input, etc.) --- by equipment, line, factory

<Auditor> 1 thermal expert and 1 electric expert
< How to audit> Preliminary survey (document review) and on-site survey: Document review, walk-through check, basic inspection (with thermometer and illuminometer) and discussion,
--------------------------------------------------------------------------------------------
<Proposal for improvement> Advice/recommendation of counter measures, estimation of E-C effect: potential/cost saving,

After follow questionnaire survey for top management --- implementation of the recommendation, energy/cost saving %,
