Airborne Hazard Transport in Buildings (312)
Problem: Need to understand how airborne hazards would be dispersed inside buildings in case of an emergency event
Project Activity Scope (from Technical Overview Chart): Mechanisms through Instruments
PNNL Solution:
- Evaluate building air handling system designs and control options
- Use multizone air flow and dispersion models to evaluate possible events for target buildings and release scenarios
- Identify key vulnerabilities and options for improved sensing and control to reduce occupant risks
- Evaluate these against requirements for efficient routine HVAC operations
Capabilities Employed to Meet Client Needs: Building dispersion modeling, HVAC system design and operation, building infiltration and ventilation mechanisms, tracer gas measurement techniques, building pressurization and blower door techniques.
