Airborne Hazard Transport in Buildings (312)

Problem: Need to understand how airborne hazards would be dispersed inside buildings in case of an emergency event

Graphic of hazards from internal releases or external air entering building

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.
