Metrics and System Evaluation

Metrics are measures used to assess and compare the performance outcomes of different systems. The metrics of building protection systems are measured indicators of the impact of a protection system on the occupants and operations of a building in the event of an attack, and most common ones include protection and operational performance metrics. 

In building protection, the primary focus is on protecting building occupants and contents. Protection metrics provide a quantifiable measure of a system s efficacy in protecting building occupants and contents. The degree of protec- 

The Immune Building Program of the Defense Advanced Research Projects Agency (DARPA) used FBE as a primary metric. FBE is defined as the fraction of the building (by volume) in which occupant exposures would exceed a prescribed level or guideline, typically evaluated as a function of the mass of agent released. 

FBE and FOE have several limitations. They do not take into account the
