Qualitative Analysis (in project) :

- Fire load,- Fire risk,- Occupation (quality of persons) (conform to British Standard)

Quantitative Analysis (in project) :

•performance-based fire prevention by fire engineer methods•Design fire•Definition of scenarios

slide 5

Performance-based fire prevention (in project) :

Three guidelines :

-Stability in fire-Smoke exhaust (evacuation of heat and smoke)-Evacuation-simulation of people

 Fire prevention in Luxembourg

slide 6

Guideline : Stability :

-Conform to Eurocodes pt. 1.2.-National annexes-Stability even while cooling down and after cooling down

slide 7

Guideline : Evacuation of heat and smoke

-Prescriptive methods conform to EN norms-General statements-Performance-based calculating (quantitative)

slide 7

Evacuation of heat and smoke :

4 types

-single storey > 3 m-single storey < 3 m (small height)-small spaces > 300 m2 < x < 600 m2 in underground)-atrium

Evacuation of people

-Egress time-Egress time compared to smoke evolution and stability-Optimizing architecture in order to reduce egress time-Optimizing number and width of issues

Procedures for authorization

-Proposal of an authorized expert -Control of scenarios, design fire by authorities and control organisations -Control of different parameters by authorities and control organisations-Calculation and simulation by expert-Control of the result by authorities and control organisations
