identifies factors affecting the energy consumption
brings up cost-effective energy saving opportunities
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

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
