2. Sweden – Building regulations for fire safety
Regulatory hierarchy
Example, hierarchy
4
Fire safety engineering – analytical design procedures

Example, combustible/timber
Structures 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 - 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. Market
Market 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
