This report aims to study cost-effective strategies to combine energy efficiency measures and renewable energy use in building renovation at the district level and to investigate factors influencing the choice of a cost-effective strategy. This is done through generic district assessments, where hypothetical, “generic” districts are generated to model typical conditions in various European countries.
For the generic districts, relevant variables were defined to carry out parametric assessments, applying and testing the methodology developed in IEA EBC Annex 75. The generic districts were generated and selected based on the typical conditions in each country, and the hypothetical nature of the assessment allowed for studying different starting conditions and renovation measures. It is, in particular, investigated to what extent there are synergies and trade-offs for combining energy efficiency measures and renewable energy measures
