3 Energy Union Prioritises Energy Efficiency Protecting vulnerable consumers Energy poverty can only be tackled by a combination of measures, mainly in the social field and within the competence of authorities on the national, regional or local levels. Providing Finance (European Fund for Structural Investment (leverage of funds for renovation) EIB Funds ERDF Funds Promoting smart technologies Putting the citizen at the centre of the energy system

8 EPBD (recast) NZEB/Cost Optimal Existing Dwellings Renewables Fabric Upgrades Cost Optimal Fabric 125 to 150kWh/m2/yr B3

9 NZEB Definition-Existing Dwellings By 2020 the target energy load for space heating, water heating, fixed lighting and ventilation in existing dwellings will be of the order of 125 to 150 kwh/m2/yr with a reasonable proportion of the remaining energy use of the dwelling coming from renewable energy sources onsite or nearby. In terms of Building Energy Rating (BER) Certificates this nearly zero energy target for existing buildings equates to a BER rating of B3 or better for fabric improvements. To bring the performance of buildings below 125kWh/m2/yr will require the addition of renewables, active ventilation systems. Decarbonisation of the grid will also help reduce the carbon impact of existing dwellings and increase the feasibility of electrical energy efficient technologies.
