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.
COMBI EEI actions
As input data for the quantification of impacts, COMBI quantifies incremental energy savings and investment costs for a list of 21 EEI actions (together with a large set of additional data and assumptions).

List of COMBI EEI actions
More information on what each EEI action covers is included directly in the “select action” menu of the online tool. And full information on actions is included in D2.2, information relevant to scenario-building in D2.2 annex.
