Project partners will analyse 5 modelling case studies to make the E1st principle operational for selected regions or countries in Europe representing differences in energy market size, structure, and policy experience. These will consider:

The user with different stakeholder perspectives

Individual building owner
Municipal perspective / city planner
Industrial / commercial zones
Overall economic perspectives
Different planning levels

Local conditions

Building stock
Existing infrastructure
Regional energy source potential

The case studies are geared to determine an optimal level of energy efficiency measures compared to alternative supply options, while achieving a certain GHG reduction target and providing the remaining supply efficiently.

Validation of the modelling findings will be carried out during a dedicated conference where weights for multicriteria analysis and results will be presented and verified with experts’ opinions (around March 2021).
