2 Possible Use of FSE Possible use of FSE in the in the Context of French context of French Regulation Regulation Armelle MULLER Armelle MULLER, Director of Director Fire department of Fire Department, CNPP FRANCE CNPP France President of SFPE French Chapter President of SFPE French Chapter

3 Overview of French Fire Regulations CODES Building Codes Labour Codes Environmental Codes DECREES Dwellings Public Buildings High Rise Buildings Workplaces Classified Facilities Nuclear Facilities OVER- ARCHING TEXTS Reaction to Fire Fire resistance Smoke Control in Public Buildings Smoke Control in Atriums Façades

4 Where Can FSE Be Used in France? Performance based regulation : the use of FSE is implicit Descriptive regulation including for some specific applications the explicit use of FSE Explicit request from administrative authorities under Derogation

5 Fields Where FSE Can Be Used CODES Building Codes Labour Codes Environmental Codes DECREES CROSS- OVER TEXTS Dwellings Public Buildings High Rise Buildings Armelle MULLER Workplaces Director of Fire department CNPP FRANCE Reaction to Fire Fire resistance Smoke Control in Public Buildings Smoke Control in Atriums Façades President of SFPE French Chapter Classified Facilities Nuclear Facilities Explicit request under Derogation by Administrative Authorities

6 Main Uses of FSE in France Nuclear Facilities Industrial Classified Facilities Public Buildings (Fire Resistance and Smoke Control)

7 How Does French Administration Achieve Confidence in FSE Projects? Public Buildings Nuclear Facilities and Industrial classified Plant Approved Consultancies National and Local Permanent Technical Authorities Local Safety Commissions Third-Party Expertise

8 Use of FSE in France Example 1: Kinetic of Collapse in Warehouses H>12,5 m Example 2: Fire Resistance of the Building Structure in relation to Evacuation from a warehouse Example 3: Evaluation of mechanical air inlet in a closed compartment in a warehouse Example 4: Smoke evacuation in a historical building Example 5: Smoke evacuation in a reconstructed prehistoric cave

9 Use of FSE in France Example 1: Kinetic of Collapse in a Warehouse - H>12,5m FSE is used to demonstrate: that walls (H>12,5m) would collapse towards the inside of the building and that no chain collapse would occur Dangerous Collapse for Rescue Services

10 Use of FSE in France Example 2: Fire Resistance of the Building Structure in Relation to Evacuation from a Warehouse FSE is used to evaluate the time available to egress before the structure collapse Concrete Températures dans les structures Température ( C) Temps (s) Risque d'effondrement inéluctable Poutre - peau Poutre - coeur Panne - peau Panne - coeur Steel

11 Use of FSE in France Example 3: Evaluation of Mechanical Air Inlet in a Closed Compartment in a Warehouse

12 Example 3: Evaluation of Mechanical Air Inlet in a Closed Compartment in a Warehouse Cas concret d application sur de l existant (bâtiment industriel) Ingénierie du désenfumage, cas d application: Use of FSE in France

13 Use of FSE in France Example 4 : Smoke Evacuation in an Historic Building Smoke evacuation cannot be designed according to prescriptive regulation. FSE is used to evaluate existing configuration (no ventilation) and alternative design Courtyard Façade City Hall in Tourcoing FR

14 Example 4: Smoke Evacuation in an Historic Building Use of FSE in France In-situ testing to evaluate existing situation Modelling of tests to calibrate the model

15 Example 4: Smoke Evacuation in an Historic Building Use of FSE in France Implementation of façade openings under the skylight, which exit the roof through ducts Openings and ducts

16 Example 4: Smoke Evacuation in a Historical Building Use of FSE in France Without ventilation Natural ventilation Mechanical ventilation 2min 5min 10min

17 Use of FSE in France Example 4: Smoke Evacuation in a Reconstructed Prehistoric Cave Grotte Chauvet

18 Use of FSE in France Example 4: Smoke Evacuation in a Reconstructed Prehistoric Cave Grotte Chauvet

19 Perspectives in French Fire Regulations Simplification Decrease building cost Impact assessment Soft Regulation Guides to propose solutions deemed satisfactory Risk assessment Many possible pathways but nobody really knows what will happen??? Possible authorization for use of CFD Egress models
