Responsive Indoor Air Quality
June 2015 – June 2018 | Brapa Consultancy
RIAQ was a research project within the European Defence Agency’s Joint Investment Programme on CBRN Protection. The project addressed indoor air quality and collective protection against chemical, biological, radiological and nuclear (CBRN) hazards.
Brapa Consultancy’s contribution
Dr. Ir. Paul Brasser was responsible for Brapa Consultancy’s work on vulnerability modelling and assessment for buildings and collective protection facilities. The role combined physics-based modelling, scientific software development and CBRN risk assessment across two work packages.
WP2: Vulnerability Assessment Tool
The work covered indoor airflow and contaminant transport modelling, the effects of ventilation and filtration, and integration of sensor information with predictive models. The modelling scope included changes in contaminant concentration over time, filter service-life assessment and support for interpreting exposure.
WP3: Vulnerability Assessment Study
The study scope involved applying simulation to building scenarios to assess exposure, compare conditions with and without protective measures, and inform the placement of sensors and filtration systems.
Connecting models with protection decisions
Brapa’s contribution connected building characteristics, ventilation, filtration and detector information to support assessment of airborne hazards and collective protection. The work brought together expertise in dispersion modelling, physical transport phenomena, toxicology and scientific software development.
