https://zenodo.org/communities/enefirst/?page=1&size=20(öffnet in neuem Fenster)A review of the background of the energy efficiency first (EE1st) principle made possible to set a practical definition, discussed the application of EE1st in key policy areas, and methodological issues for comparing demand-side resources with supply investments:

https://enefirst.eu/implementation-maps/(öffnet in neuem Fenster) This was completed with guidelines going further, from sectoral to integrated approaches, with a focus on energy planning and investment schemes. This also included an analysis of the new fit-for-55 package, focusing on provisions relevant to EE1st:

https://enefirst.eu/wp-content/uploads/Enefirst_Policy-briefing_RAP_Final.pdf(öffnet in neuem Fenster) ENEFIRST developed as well model-based assessments of the impacts of implementing EE1st, starting with reviewing the possible approaches for quantitative joint assessments of demand and supply side resources:
https://enefirst.eu/wp-content/uploads/D3.1_QuantitativeApproaches.pdf(öffnet in neuem Fenster) The ENEFIRST model-based assessment aimed at comparing three EU scenarios meeting carbon neutrality in buildings in 2050 with different levels of ambition for energy efficiency in buildings and the related impacts on the whole EU energy system (assessing total energy system costs):
https://enefirst.eu/wp-content/uploads/D3.2_ModelConceptDevelopment-1.pdf(öffnet in neuem Fenster) The results from these 3 EU scenarios provide quantitative evidence that at least moderate levels of energy efficiency in buildings are needed to cost-efficiently achieve carbon neutrality by 2050, which means going much beyond business-as-usual trends:

https://enefirst.eu/wp-content/uploads/D3.5_CaseStudies_Report_compressed.pdf(öffnet in neuem Fenster) The potential for implementing EE1st in three countries with very different contexts (Germany, Hungary and Spain) was explored
