Persontäthet vid utrymningsberäkningar

Sammanfattning

The aim of this study is to evaluate whether the value of occupant load is over or under estimated when the Swedish general value for department stores, 0,5 person/m2, is used for dimensioning shopping centers. The data that was analyzed derives from seven shopping centers and one department store. A conservative method was used to calculate the occupant load factor. The analysis shows that two groups can be discerned: one group that is characterized by a lower occupant load factor that does not exceed 0,3 person/m2, and one group with a higher occupant load factor. Shopping centers with a higher occupant load factor are located centrally in large urban areas. The remaining shopping centers are found outside of urban areas or in the outskirts of cities. The recommended value 0,5 person/m2 is exceeded in only 0,3 % of 41 322 registered values. The geographic location should be taken into consideration when dimensioning and evaluating the occupant load of shopping centers. The occupant load factor increases during holidays.
