Abstract
Dette speciale adresserer et praktisk behov hos bygningsejere og rådgivere for at kunne prioritere store bygningsporteføljer efter brandrelateret risiko og potentiel forretningspåvirkning. Forskningsspørgsmålet er, hvilke målbare indikatorer der kan udvikles, så brandrisiko og forretningskonsekvenser kan vurderes og sammenlignes på tværs af bygninger som grundlag for en tidlig prioritering. Indikatorerne blev identificeret gennem brainstorms, ekspertinterviews og litteraturstudier, videreudviklet ved at opstille hypoteser og risikopåvirkningsfaktorer, og gjort operationelle via risikoscores baseret på sværhedsgrad og vægtning. Fem brandindikatorer (bl.a. beliggenhed, risikofyldte rum, bygningens anvendelse, størrelse og materialer) blev fuldt operationelle, og to (antal etager og gasinstallationer) delvist. Derudover blev fem forretningspåvirkningsindikatorer operationaliseret (fysiske tab, driftsafbrydelse, kritiske forretningsfunktioner, omdømme og compliance). Risikoscorene muliggør sammenligning og prioritering af bygninger og kan danne et foreløbigt risikobillede til at målrette inspektioner og forebyggelse; samtidig peger arbejdet på, at sikkerhedstiltag kan indgå som risikoreducerende indikatorer. Specialet konkluderer, at øget adgang til data vil kunne forbedre indikatorernes præcision og bane vej for udvikling af yderligere indikatorer.
This thesis addresses a practical need for building owners and advisors to prioritize large building portfolios by fire-related risk and potential business impact. The research question asks which measurable indicators can be developed to evaluate and compare fire risk and business consequences across buildings as a basis for early prioritization. Indicators were identified through brainstorming, expert interviews, and literature review, then further developed by formulating hypotheses and risk influence factors, and made operational via risk scores constructed from severity and weighting. Five fire indicators (including location, presence of risky rooms, building use, size, and materials) were made fully operational, and two (number of floors and gas installations) partially. In addition, five business impact indicators were operationalized (physical losses, business interruption, critical business functions, reputation, and compliance). The resulting risk scores enable cross-building comparison and prioritization to guide inspections and mitigation, and the work suggests that safety measures can serve as risk-reduction indicators. The thesis concludes that improved data access would enhance indicator accuracy and support the development of additional indicators.
