Overview
The Ventilation and Filtration category provides engineering and building-physics solutions responding to the core intervention stage: "What now? How do we mitigate poor indoor air quality?" As demonstrated in the EDIAQI Decision Tree, when outdoor pollution is high, filtration is required; when indoor emissions accumulate, adequate ventilation and local extraction are imperative.
Drawing directly from research conducted by Tallinn University of Technology (TalTech) and the EDIAQI Filtration Pilot (P4 led by ASC), this category synthesizes empirical data and scientific testing on air cleaner efficiencies, filter loading dynamics, ventilation rates, and energy-efficient building operations.
Key Engineering Aspects
- Ventilation Dynamics: Air exchange rate estimation using passive tracer gas decay (CO2 decay method), mechanical ventilation strategies, and natural ventilation optimization.
- Air Filtration Principles: Performance of portable air cleaners (PACs), filter media classification (EN 779, ISO 16890, EPA/HEPA/ULPA standards), and real-life CADR determinations in occupied buildings.
- Source Capture & Containment: Local exhaust ventilation, kitchen cooker hoods, and reducing indoor chemical transformations.
- DIY and Novel Solutions: Performance, noise levels, and flow-field characteristics of low-cost do-it-yourself air cleaners (e.g., Corsi-Rosenthal boxes) versus commercial certified units.
