The COMBI online tool: evaluating the impacts of the energy efficiency policies

The COMBI project aimed at quantifying the multiple non-energy benefits of energy efficiency in the EU-28 area. It gathered existing approaches and evidence from the EU area and developed modelling approaches for impacts on emissions, resources, social welfare, macro economy and the energy system.

The COMBI project aimed at quantifying the multiple non-energy benefits of energy efficiency in the EU-28 area. It gathered existing approaches and evidence from the EU area and developed modelling approaches. All data is analysable via a graphic online-visualisation tool with data export function: https://combi-project.eu/tool/

 

To this end, an aggregation methodology has been developed to avoid double-counting, deal with other aggregation issues and for presenting the various impacts on their various dimensions. Finally, insights for policy relevance were derived and policy recommendations elaborated to facilitate the communication of the non-energy benefits in the relevant policy areas.

 

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).

 

The difference between the baseline and efficiency scenario is used as input data (i.e. incremental energy savings and investment costs) for quantifying multiple impacts. Also, only incremental multiple impacts are quantified. This means, COMBI quantifies the additional multiple impacts of more ambitious policy action. One goal of COMBI scenarios and impact quantification was to provide a bottom-up funding of the scenarios modelled for the EU-Commission’s EED Impact Assessment and its annexes (based on PRIMES et al.).

 

The COMBI tool allows to visualize:

  • multiple impact quantifications;
  • additional impacts resulting from additional EE improvement actions in the year 2030;
  • standard values are annual/annualised (can be recalculated to action-specific life-time values) visualisations customisable by impacts/actions/countries;
  • data export function below graph.

Results are presented in 3 steps: physical values, monetary values and Cost-Benefit Analysis (if impacts not double-counted).

 

The expert mode (available after free registration) allows further features.
