Public Programs on Energy Conservation Auditing Performed by ECCJ

1 day-Energy Audit for Factories and Buildings

one-day on-site examination by thermal and electric experts
free of charge ----- subsidized by Japanese Government

Details of investigation/audit conducted
(Examples of general management matters and steam system)

Energy management system: Management organization, human resource development, energy-saving target, investment budget, medium- to long-term planning, implementation status of energy conservation, utilization of public subsidization, etc.
Measuring and recording: Measuring instruments installed, how the instruments are being used, maintenance of the instruments, periodical measurements and records.
Maintenance management of equipment: Periodical and daily inspections, record of repair work for leakage of water, steam and others, heat insulation, cleaning of filters, strainers and others.
Management of energy consumption: Recording in the daily report (daily consumption, monthly consumption), a graph showing year-on-year rate.
Management of unit consumption rate for main products: Energy consumption rate compared to shipment value; energy consumption rate compared to production quantity
Management of environment-related matters: Wastewater treatment, waste disposal, waste reduction, separation of waste, recycling effort, etc.
Improvement of process: Improvement of operation, review of line layout, process made for continuous and highly efficient operation

Operation management of steam: Aridity, carry-over, preset setting pressure and temperature of steam, flow volume of steam
Management of steam leakage and heat insulation: Piping system, tank, loaded equipment
Proper fitting of the steam piping system: Route, pipe size, disposal of unnecessary piping, integration of plural piping systems
Leveling of Steam loading condition: Installation of accumulators, use of vacuum pump for the ejector, other measures for loaded conditions
Recycling of steam drain: Recovery of steam pressure (back pressure turbine), management of steam trap, place where recovered drain is sent, recovery system, use of flush steam. (The rest is omitted.)
