Abstract Comparing results obtained in Virtual Reality to those physical experiments is key for validation of as a research method the field Human Behavior Fire. A series based on similar evacuation scenarios high-rise building with elevators was conducted. The consisted experiment building, and two virtual representation same building: one using Cave Automatic Environment (CAVE), head-mounted display (HMD). data HMD compared CAVE experiment. three datasets were terms pre-evacuation time,...
Abstract Past studies suggest that people are often reluctant to use occupant evacuation elevators in case of fire. However, existing research is scarce and current knowledge based on questionnaire laboratory experiments. An unannounced experiment was therefore performed the 16th floor a 35-floor high-rise hotel building. Sixty-seven participants took part eye-tracking glasses were used collect data exit choice eye fixations. Three different scenarios studied, including two room locations...
In order to provide a reliable evacuation design assessment, data showing the variation in pre-movement time is of vital importance. The many cases regarded as main period during an assessment. Therefore, forty unannounced experiments for six different occupancies were analysed quantify building evacuation, i.e., taken between receiving first cue and initiation movement towards exit evacuation. office, cinema theatres, restaurants, department stores night clubs. equipped with types alarm...
Summary The impact of different passive protective measures against external vertical fire spread was investigated using the numerical tool Fire Dynamics Simulator (FDS). study divided into a validation and comparative analysis. performed to evaluate FDS as calculation for modelling conducted experimental results from large‐scale test done on SP FIRE 105 rig at SP, Sweden. It concluded that 6.2.0 could reproduce with reasonable level detail. In analysis, smaller apartment studied in...
Elevator evacuation is associated with several safety benefits and can be a cost-efficient strategy in many buildings or facilities. Despite the advantages, elevator not yet common built environment. In this paper, design that allows designer to consider information needs of evacuees when designing guidance measures for elevators presented. The based on human behaviour theories Theory Affordance. use also illustrated case study, i.e., an underground metro station elevators. This study...
Abstract This short communication presents the findings of work conducted by human behaviour in fire permanent working group International Association for Fire Safety Science. Its aim is to identify determinants research gaps field fire. Two workshops were 2023 which identified and discussed twenty experts. The led experts through a series questions determine reasons (or determinants) these building fires wildfires. Through questions, primary (1) researchers’ literacy variety methods adopted...
This paper investigates evacuation from a specific floor plan to determine if elevators can replace one of the escape routes consisting staircase without lengthening times. study specifically studies single office with 360 and 540 occupants, designed as fire compartment an area 2800 m2. To specify occupants’ willingness use elevator for different floors, three functions are used. These modified include more floors used derive distributions proportion using staircases elevators, by...
The construction sector is of great importance to the Swedish economy, but its impact on climate significant and accounts for about 40% Sweden's total energy consumption. also generates a share material flows waste quantities in society. Thus, due large sector, there are opportunities contribute positively by reducing through change modernization. There many activities focused various ways issue product reuse has received increasing attention recent years. However, very little work products...
