The Core Audit

makes an evaluation of the present consumption

identifies and quantifies the feasible energy saving possibilities

produces a report

Targets

Total picture of the use of energy, its distribution and costs

Energy saving potential and the possibilities to use renewable energy sources

Listing of all economically feasible proposals for energy saving measures (single pay-back time < 10 a)

Voluntary energy conservation agreement:

significant carrier for energy audits in all sectors except the transport sector

partners to the agreements are “obliged” to carry out energy audits and to reach a set coverage within a certain time

• The government finances the costs of the operating agent (Motiva) of the Finnish energy audit program and gives 40…50 % support for the energy auditing project expenses

• 15…20 % subsidies for conventional energy saving investments for companies who have joined the voluntary Energy Conservation Agreements with the Government.

• Higher subsidies (20..25 %) has been granted for ESCO

investment projects at least until the end of the year 2004 by the government

Monitoring and Reporting of Energy Audits

All energy audit results are filed

Buildings divided into 31 types and industry in 8 subsectors

About 31700 proposed energy saving measures filed• Division in 29 categories• Data on each measure: Savings (kWh and EUR) and

investments (EUR)

Three phase data collection• After granting the subsidy -> Volume in the pipeline• After submitting of EA reports -> proposed measures and

saving potential• Voluntary Agreement Reporting -> Status of implementation

Motiva Oy reports monthly on volumes and annually on results
