1. Sweden - “map of fire research”
SP Fire Research• Full equipped, accredited fire lab• Fire resistance• Reaction to fire• Fire dynamics• Tunnels, vehicles, teaching,
standardization, simulation
SP Project leader Sustainable Built Environment• Unit: Wood building technology• Fire resistance• Modelling of timber• Reaction to fire• Ecobuild: Material science
Lund University• Fire Safety Engineering• IMFSE (Gent, Edinburgh, Lund)• Active fire safety
Luleå technical University• Fire Safety Engineering• Steel structures• Construction techniques
2. Sweden – Building regulations for fire safetyRegulatory hierarchy
4
Example, hierarchy
5
Fire safety engineering – analytical design procedures
6
Example, combustible/timberStructures can be in timber, no limit on height or number of storeys, if fire resistance requirements are fullfilled (R 60- R 120)
Load-bearing resistance (general)• R30 for single houses• R60 up to 8 story
Reaction to fire• Limitations of the linings in escape routes• Compensation of combustible insulation by means of linings
Facades• Façade test available• Combustible façade, more than 2 story: fire retardant
treatment or sprinkler

3. Projects - finalized• Fire In Timber European Guideline
• Reliability (nat. project)
• I-joists in wall elements
• Durability of fire retardant treatments
• Nordic-Baltic guideline INT 1 INT 2 EXT
3. Projects - ongoing• Cellulosic fibre insulation (nat. project)
• Fire Safety and Execution (scand. project)
• Parametric fire design (nat. project)
• Fire Safety Engineering (scand. project)
• Fire stops (nat. project)
• Revision of Eurocode 5
4. MarketMarket of timber buildings between 10 and 15% (multi story timber buildings)
Trends
•More architectural design
•More visible wood
•Wooden buildings in larger cities, e g Stockholm
•Higher buildings
but also
•Accident
•Insurance concerns
5. Challenges• Insurance of timber buildings
• Fire stops (in the construction, between parts, in
ventilated façades…)
• Tall timber buildings
• Education
