Tekniska system för uppskattning av personantal och personers placering i byggnader

Sammanfattning: The aim was to identify technical systems potentially useful for estimating number of people and their location in buildings. Another aim was to investigate whether the information generated by the technical systems can have a positive effect on risk management. A number of technical systems were identified and evaluated. A more detailed evaluation of demand-controlled ventilation system with carbon dioxide measurement was performed. Through the detailed evaluation a method for estimating people with demand-controlled ventilation system was derived since this technical system was not originally intended for estimating the number of people. The evaluation showed that demand-controlled ventilation system have potential to be used for estimating number of people in buildings. The evaluation also showed that the ventilation conditions and generated carbon dioxide per person had the largest influence on the derived method and therefore needs further investigation. The evaluation of all identified technical systems showed that because of their different qualities there are systems that are better than others at estimating number of people in buildings. The evaluation also indicated that a combination of systems could improve the results of estimating number of people in buildings.
