1 COST Action FP1404 Fire Safe Use of Bio-based Building Products 1 Sweden Fire safety in regulations, research and future challenges Joachim SCHMID, SP – Wood building technology David LANGE, SP – Fire Research Barcelona, and

2 2 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 leaderSustainable 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

3 2. Sweden – Building regulations for fire safety Regulatory hierarchy

4 4 Example, hierarchy

5 5 Fire safety engineering – analytical design procedures

6 6 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

7 7 Example, combustible/timber 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

8 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

9 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

10 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

11 5. Challenges Insurance of timber buildings Fire stops (in the construction, between parts, in ventilated façades…) Tall timber buildings Education
