Guidelines on policy design options for the implementation of E1st in buildings and the related energy systems

The latest report from the ENEFIRST project adds a holistic perspective to the concept of Energy Efficiency First (E1st) and provides guidelines to promote integrated approaches for implementing E1st across different policy areas within the energy system.

This contribution aims to break the silos in policymaking and implementation, with a focus on energy planning and investment schemes in the buildings and related energy sectors, where supply-side and demand-side options can be considered jointly to provide long-term benefits to society and the energy system as a whole.

The report also provides a targeted review of the Fit-for-55 package proposed by the Commission in July 2021, analysing the new or revised provisions that can be connected with the implementation of the E1st principle. It is complementary to the Recommendation and guidelines on Energy Efficiency First published by the European Commission in September 2021.
