Summary of the PM Working Group Discussion on Submicron and Ultrafine Particles Two sessions within the Particulate Matter (PM) Working Group have highlighted a critical shift in air quality monitoring: the move away from traditional mass-based measurements toward tracking the number and surface area of the smallest particles. While PM2.5 is currently well-regulated, the scientific community is increasingly concerned about submicron and ultrafine particles (UFP), which pose unique health hazards that mass-based metrics fail to capture.

Why the GO IAQS Score Replaced Conventional “Green” The shift from the conventional "Green" to the specific "Blue" hue in the GO IAQS Score represents a significant evolution in how we communicate environmental health. While green has been the conventional way for "Good" for decades, GO AQS has prioritized accessibility and psychological resonance over tradition. Here is why the transition to #658eff is more than just a stylistic choice.

A Synthesis of Expert Views on Submicron and Ultrafine Particles For decades, the global standard for measuring indoor air quality (IAQ) has focused on PM2.5, particulate matter with an aerodynamic diameter of 2.5 micrometers or less. However, recent findings from the Particulate Matter Working Group suggest that this mass-based metric may be overlooking the most significant health risks. By synthesizing expert survey data and recent literature, we can now map the critical landscape of submicron and ultrafine particles.

The EU’s New EPBD: Why Indoor Air Quality Needs a Unified Standard The recently updated Energy Performance of Buildings Directive (EPBD) is a pivotal legislative framework aimed at improving the energy efficiency of buildings across the European Union. While its primary focus remains on energy savings and decarbonization, the revised EPBD now formally recognizes the crucial link between energy performance and Indoor Environmental Quality (IEQ). This update requires member states to address IEQ in their national legislation, ensuring that energy-efficient buildings also support the health, comfort, and well-being of their occupants.
