The June issue of the REHVA Journal is now out!
This issue focuses on "EPBD IV (2024) Implementation on its Way & Shaping the Future of EPB Standards".
The transposition deadline of 29 May 2026 for the recast Energy Performance of Buildings Directive (EU/2024/1275) has now passed, and this issue takes stock of where Europe stands. Contributions from REHVA member associations in Denmark, Finland, France, Latvia, the Netherlands, Spain and Poland offer a firsthand picture of national implementation efforts, a mixed landscape, with some countries notifying complete transposition and many others still working through complex legislative processes. These country reports are complemented by articles on the legal architecture of the EPBD, REHVA's science-based advocacy work through EUPAG, and tools to bridge the gap between regulatory compliance and real energy efficiency performance. The issue also covers the concluded MODERATE project and its open-source infrastructure for building energy data, a study on ceiling fans and office furniture as a low-energy cooling strategy, and a two-part series on ventilation component EPDs and building life cycle assessments. An interview on shifting from prescriptive to performance-based approaches in residential ventilation design rounds out the technical content. REHVA news from the 2026 Annual Meeting in Nice and the Student Competition complete the issue.
