COMBI input data
COMBI provides estimates of the major multiple impacts of the energy efficiency potential that goes beyond an existing policies scenario in the year 2030. Impacts are quantified by EU member state and by single energy efficiency improvement (EEI) action. Therefore, detailed input data on energy savings and investment costs are necessary: COMBI uses detailed stock models to this end. The COMBI input data modelling exercise produced a baseline scenario (based on existing EU legislation) and an efficiency scenario (based on ambitious assumptions on technology implementation following more ambitious policies), resembling the EUCO+33 scenario of the EU EED impact assessment.
