The 2026 Buildings Performance Institute Europe (BPIE) Energy Performance of Buildings Directive (EPBD) Library brings together publications that support EU Member States in implementing the EPBD. Each entry includes a short description, a link to the source, and indications of whether the publication covers practices from specific Member States or contains concrete examples of good practice. The collection is designed to assist national authorities ahead of the transposition deadline of 29 May 2026.

A significant part of the library addresses how Member States can plan and structure the improvement of energy performance in their building stock. The publications examine national renovation planning, the development of renovation trajectories, and the integration of sufficiency measures into long‑term strategies. These analyses outline how building stock data, segmentation, and performance indicators can support targeted energy‑efficiency policies.

The library also covers instruments that facilitate energy‑efficient renovation. This includes material on renovation passports, one‑stop shops for building performance, and databases for energy performance information. Additional reports explore methodologies for assessing energy efficiency, such as climate‑corrected energy consumption, energy intensity, and per‑capita energy use. Several documents provide examples from Member States that illustrate how these approaches can be applied in practice.
