- Abstract (Swedish)
- Malmös universitet Niagara började byggas 2009 och invigdes 2015. 2009 avgjordes en arkitekttävling där deltagarna skulle presentera en design på byggnaden. Vinnaren blev designföretaget Lundgaard & Tranberg som skapade en byggnad som består av tre huskroppar med ett stort, öppet atrium i mitten. Niagara har sedan 2015 brukats, till största del för, universitetsundervisning och kontorsarbete. Denna rapport analyserar byggnadens befintliga brandskydd där personskador på individer som vistas i byggnaden står i fokus. Rapporten kommer inte beakta samhällsperspektiv eller ekonomiska perspektiv.

Vinnaren blev designföretaget Lundgaard & Tranberg som skapade en byggnad som består av tre huskroppar med ett stort, öppet atrium i mitten. Niagara har sedan 2015 brukats, till största del för, universitetsundervisning och kontorsarbete. Denna rapport analyserar byggnadens befintliga brandskydd där personskador på individer som vistas i byggnaden står i fokus. Rapporten kommer inte beakta samhällsperspektiv eller ekonomiska perspektiv.
I analysen presenteras skadekriterier i form av maximal temperatur och strålning samt en minimal sikt. De är framtagna för att kunna avgöra huruvida en säker utrymning kan ske. Identifierbara risker representeras med hjälp av tre framtagna brandscenarier. Scenarierna illustreras med hjälp av simuleringar i FDS och Pathfinder där FDS simulerar brandens fysiska egenskaper och Pathfinder personernas utrymning. Resultaten visar att människor kommer att befinna sig i kritiska miljöer i två utav tre antagna brandscenarier. I båda fallen är det enbart sikten som blir kritisk.
En kvalitativ tolkning av resultatet leder till att människor kan utrymma utan skador trots att resultatet i sig tyder på att utrymningen är osäker. Det kritiska värdet på sikten kan antas obetydligt för personer i situationer som exempelvis köer eftersom köande har nära till personen framför sig. Rapporten hävdar att brandcellsgränsernas skydd mot rök och brandmiljöer vid trapphusen är en vital del av byggnadens brandskydd. Således bör de funktioner som upprätthåller denna brandavskiljning underhållas genom kontinuerlig service. (Less) - Abstract

The report will not consider the perspectives of social or economic aspects.
The analysis presents threshold values in terms of maximum temperature and radiation and also minimal vision. If a value exceeds the crucial value, the environment is considered critical. The values are produced to decide whether the evacuation is safe or not. The identifiable risks are represented by three produced scenarios. The scenarios are illustrated by simulations in Pathfinder and FDS were FDS simulates the fire’s physical characteristics and Pathfinder the evacuation of people. The results show that people will happened to be in a critical environment in two of the three scenarios. Only the vision is critical in both cases.
A qualitative interpretation of the results implies that people are able to evacuate safely even though the result itself states that the evacuation is unsafe. The critical value of the vision can be assumed to be meaningless for people in situations like queues because a person in a queue has people a short distance in front itself. The report states that the stairwells protection against fire and smoke is a vital part of the total fire protection of the building. Therefore, the functions that maintain the environmental differences between the stairwell and the outside should go through inspections continuously. (Less)
