Specific prescriptions : -Office buildings, -Assembly rooms -Underground Parkings -Hotels -Restaurants -Shopping centers -Hospitals and homes for elder people -Residential buidings -Building sites Fire prevention in Luxembourg slide 3

Qualitative Analysis (in project) : -Fire load, -Fire risk, -Occupation (quality of persons) (conform to British Standard) Fire prevention in Luxembourg slide 4

Quantitative Analysis (in project) : performance-based fire prevention by fire engineer methods Design fire Definition of scenarios Fire prevention in Luxembourg 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 National annexes -Stability even while cooling down and after cooling down Fire prevention in Luxembourg slide 7

Guideline : Evacuation of heat and smoke -Prescriptive methods conform to EN norms -General statements -Performance-based calculating (quantitative) Fire prevention in Luxembourg slide 7

Evacuation of heat and smoke : 4 types -single storey > 3 m -single storey < 3 m (small height) -small spaces > 300 m 2 < x < 600 m 2 in underground) -atrium Fire prevention in Luxembourg slide 7

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 Fire prevention in Luxembourg slide 8

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 Fire prevention in Luxembourg slide 9
