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.

Extreme heat is an urgent and growing public health threat, driven by climate change and exacerbated by urbanization and population ageing. It increases morbidity and mortality, strains health and social care systems, and disproportionately affects populations at increased risk. Heat–health action plans (HHAPs) are a core public health response, enabling countries to anticipate and prepare for extreme heat, protect populations at increased risk, strengthen health system resilience, and reduce avoidable illness and deaths. This second, updated edition of WHO guidance on HHAPs supports countries in developing, strengthening and implementing such plans at national, regional and local levels. It offers an implementation-oriented framework, structured around eight core elements: governance; heat–health warning system; populations at increased risk; communication; health system resilience; reducing heat exposure; heat–health surveillance; and monitoring, evaluation and learning. The guidance also includes user action briefs for key sectors and a public health message bank to support effective risk communication with the public. It translates accumulated evidence and implementation experience into practical actions, tools and decision points for coordinated heat–health risk prevention and response. While tailored to the WHO European Region, it is adaptable to other contexts.

For the 11th time, DYNASTEE will organise a Summer School on the application of analysis techniques towards whole building energy performance assessment from in-situ measurements and metering data. The Summer School (SS26) is organised in the framework of the IEA-EBC … Continue reading →

The qualification of airtightness testers plays a key role in ensuring the reliability, consistency, and credibility of building airtightness measurements, which are essential for energy performance assessment, indoor environmental quality, and compliance with building regulations. Over the past decades, several countries and professional organizations have developed qualification and certification schemes for airtightness testers in order to improve measurement quality and increase confidence in reported results.
