Within the COMBI modelling/quantification work, more than 35 individual impacts are quantified, following individual cause-effect chains from energy efficiency improvement (EEI) actions to the impacts. They cover the categories outdoor air pollution/health, building conditions/health and productivity, resource impacts, macroeconomic impacts and energy system/security. Some of the 35+ individual impacts are quantified in the same physical units (e.g. health impacts, resources) and can thus be pre-aggregated to give a simplified overview.
Pre-aggregated COMBI impacts
|#||Impact (pre-aggr.)||Unit (physical)||No. of sub-impacts|
|2||eco-systems: acidification, eutrophication, ozone exposure||% change in area affected||3|
|3||eco-systems: crop loss||% change in area affected, t of crop loss||1|
|4||air pollution emissions (mid-points)||t||nr. of pollutants|
|5||avoided GHG emissions||t CO2eq||2|
|6||material footprint/resource impacts||t||4|
|7||energy cost savings/available income effect||€||1|
|8||productivity||work days lost||3|
|9||gross employment/GDP (temporary)||job years||1|
|10||public budget (temporary)||% of budget or GDP||1|
|11||energy security||import expenses as share of GDP||1|
|12||energy system: Value of lost load||% €||1|
