BCAR Tornado Methodology Report
The Tornado Safe Room Module provides a methodology for determining life safety benefits (injury and death prevention) from tornado safe rooms within the updated Benefit Cost Analysis (BCA) software. This module is an update to the Benefit Cost Analysis (BCA) software included in the 1st Edition (07/2000) of FEMA 361, Design and Construction Guidance for Community Shelters (FEMA 361). The original software focused on the reduction of injuries and deaths from safe rooms for tornados and hurricanes. Beginning in 2007, in parallel to revisions to FEMA 361, FEMA initiated a redesign of all BCA software associated with their grant programs, including flooding, earthquakes, hurricane winds, and tornadoes. The decision was made by FEMA to develop new BCA software for life safety benefits of safe rooms with separate modules for tornado and hurricane hazards. As the new Tornado Safe Room and Hurricane Safe Room Modules software are finalized, they will be used in place of the original safe room (shelter) BCA software.
