Anlagd brand –Analys av kostnader och nyttor med tekniska system

The project “Arson - a societal problem” has been running with funding from a number of players since 2008. The project consists of a number of sub-projects and the work presented in this report was conducted within the sub-project: "Technical- and risk-based methods to prevent and mitigate the consequences of arson". In this report a cost-benefit analysis of several different technical systems are performed on two reference buildings. The analysis shows that the technical systems are beneficial in areas where there is high risk of arson. However, none of the studied systems can be justified on a national level, because there are big differences between different schools and cities. For example there are differences in fire frequency and potential damage on a specific school.
