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 … Continue reading →

Poor indoor air quality is a common and preventable public health risk that contributes to chronic disease, infectious disease transmission, and economic losses. Europe’s updated Energy Performance of Buildings Directive integrates indoor environmental quality into building policy for the first time, representing a major opportunity for Europe to protect the health of building occupants and set an example for the world. With a May 2026 deadline approaching, EU Member States should adopt a health-based framework for indoor air quality and aim to harmonize standards across Europe.

PROGRESS BUT INSUFFICIENT AND UNEVEN  The EU BCT shows a marked acceleration of building decarbonisation in recent years. After the index fell to –0.5 points in 2021, it increased sharply to 11.9 points in 2022 and further to 19.2 points in 2023, representing the strongest consecutive improvements since the start of the tracker. However, part of this progress […]

What IAQ Pilot Results Could Unlock Across Europe and Beyond

We breathe approximately 10,000 to 12,000 litres of air every day, and for most people in Europe, over 90 percent of that air is inhaled indoors. Yet this air can contain a complex mixture of pollutants, including particulate matter, volatile organic compounds, and biological contaminants, all of which are associated with significant health risks, particularly for children. 

Are you working in indoor air quality, public health, environmental monitoring, or bioaerosol research? The European Commission’s Joint Research Centre (JRC) is conducting a short survey to better understand activities and interest in Indoor Air Surveillance, particularly for detecting biological agents relevant to human health.

IEA EBC Annex 97, Sustainable Cooling in Cities, held a policy seminar in Madrid on 22 April 2026, titled “Policy in Practice: The Spanish Urban Perspective on Sustainable Cooling.” The event brought together international Annex experts, Spanish policymakers, city representatives, … Continue reading →

In this Expert Talk, Professor Olesen reflects on the evolution of thermal comfort, questioning the adequacy of traditional steady-state models in capturing real occupant experiences in today’s dynamic environments. He also addresses the persistent gap between established standards and the actual performance of buildings in practice, highlighting where current approaches may fall short. The discussion further explores the growing importance of integrating indoor environmental quality within the Energy Performance of Buildings Directive (EPBD) framework and what is needed to translate policy into tangible improvements. Finally, he shares his perspective on the priorities that should shape future standards, particularly in balancing energy efficiency, occupant wellbeing, and performance in the face of climate change.

Europe’s overlapping crises — from energy insecurity and climate change to unaffordable housing and eroding democratic trust — share a common thread: the quality of the buildings and neighbourhoods where people live. Drawing on five years of real-world experience across the oPEN Lab Living Labs in Genk (Belgium), Pamplona (Spain) and Tartu (Estonia), the roadmap demonstrates that the neighbourhood scale is uniquely suited to integrate deep renovation, […]

The ASHRAE Global Occupant Behavior Database aims to advance the knowledge and understanding of realistic occupancy patterns and human-building interactions with building systems. This database includes 34 field-measured occupant behavior datasets for both commercial and residential buildings, contributed by researchers from 15 countries and 39 institutions covering 10 different climate zones. It includes occupancy patterns, occupant behaviors, indoor and outdoor environment measurements.
