Abstract

Purpose

In recent years, the number of high-rise buildings in Malaysia has been increasing. Therefore, it is essential to take evacuation into consideration especially for emergency conditions such as fire, explosion and natural disasters. This research aims to evaluate the effectiveness of the escape time in typical Malaysian high-rise residential buildings.

Design/methodology/approach

This work comprises simulation on three buildings around the Selangor area in Malaysia. Quantitative methodology is adopted using Pathfinder software to simulate the evacuation process and time of the three typical Malaysian high-rise residential buildings. Four parameters were studied namely, the occupant load density, walking speed of first and last occupants, average of evacuation time per floor for the three buildings and effect of placement of emergency staircase on travel time.

Findings

Findings show that 12 m2 which is double the allowable occupants' density in Malaysia increases evacuation time by 67.9% while the placement of the emergency staircase on the left and middle section of a building significantly affects the evacuation time by 21.2%. In conclusion, from the simulation studies, it is recognized that a higher occupant's density affects the evacuation time.

Originality/value

This work could provide information on escape time for future construction of high-rise buildings in Malaysia. Hence, the specification and design of buildings could be reviewed based on the results obtained from this simulation. This information could be beneficial to the building regulators and developers thus enhancing the knowledge of building constructor and possible issues in the design of staircases, corridors and height of buildings.

Abstract

Purpose

The purpose of this study is to develop optimal evacuation plan to provide valuable theoretical and practical insight in the fire evacuation work of similar structures, by proposing a systematic simulation-based guided-evacuation agent-based model (GAM) and a three-stage mathematical evacuation model to investigate how to simulate, assess and improve the performance efficiency of the evacuation plan.

Design/methodology/approach

The authors first present the self-evacuation and guided-evacuation models to determine the optimal evacuation plan in ship chamber. Three key performance indicators are put forward to quantitatively assess the evacuation performance within the two fire scenarios. The evacuation model in tower is built to obtain the dividing points of the three different fire evacuation plans.

Findings

The study shows that the optimal evacuation plan determined by the GAM considering social relationships effectively relieves the congestion or collision of evacuees and improves the evacuation uniformity. The optimal evacuation plan not only solves the crush caused by congestion or collision of evacuees but also can greatly shorten the evacuation time for passenger ship fire.

Originality/value

This study establishes the GAM considering the interactive evacuee characteristics and the proportion of evacuees guided by the crew members to make the optimal evacuation plan more time-efficient. The self-evacuation process is simulated to assess the performance of the guided-evacuation strategies, which are used to verify the effectiveness and feasibility of the optimal evacuation plan in this research.

– The purpose of this paper is to study the behavior of smoke flow in a typical high-rise residential building fire in six common smoke control systems.

Abstract

Purpose

The purpose of this paper is to study the behavior of smoke flow in a typical high-rise residential building fire in six common smoke control systems.

Design/methodology/approach

The pressure, temperature and CO2 concentration were used to trace the motion of turbulent smoke flow through CFD.

Findings

It is found that the hot smoke could rise up and spread into the indoor space on the upper floors through the staircase. When the pressure in the evacuation staircase is higher, it would be more difficult for the smoke to enter the staircase and transport vertically. On the other hand, the smoke would soon transport to the indoor space on the upper floors horizontally. During this process, the smoke shows a more disorder horizontal transport under the sole effect of thermal buoyancy than the co-existence of thermal buoyancy and the air inlet.

Research limitations/implications

Because of the chosen research approach, the research results may need to be tested by further experiments.

Practical implications

The paper includes implications for the design of smoke control systems and evacuation in a building fire.

Originality/value

This paper fulfils an identified need to study the behavior of smoke in a fire and optimize the design of smoke control systems.

Abstract

Purpose

The purpose of this paper is to conduct a comprehensive study on building, fire and evacuation, so as to effectively improve the efficiency of building fire evacuation and the management level of fire evacuation site. Make up for the difficulties of BIM technology in effectively connecting building information and fire data.

Design/methodology/approach

First, this paper establishes a fire model and an evacuation model based on BIM information. Then, the safety index (SI) is introduced as a comprehensive index, and the IRI is established by integrating the SI function to evaluate the safety of evacuation routes. Based on these two indices, the IRI-based fire evacuation model is established.

Findings

This study offers an Improved Risk Index (IRI)-based fire evacuation model, which may achieve effective evacuation in fire scenes. And the model is verified by taking the fire evacuation of a shopping center building as an example.

Originality/value

This paper proposes a fire evacuation principle based on IRI, so that the relevant personnel can comprehensively consider the fire factors and evacuation factors to achieve the optimization of building design, thereby improving the fire safety of buildings.

Abstract

Purpose

The purpose of this paper is to investigate human behaviour under a situation of fire in high-rise residential buildings and identify the factors that motivate people to evacuate.

Design/methodology/approach

A literature review was conducted to identify different factors of human behaviour during a situation of fire and identify challenges during the evacuation. Through a mixed research method approach, the paper identifies human background, experience and knowledge with fire safety. The paper discusses the challenges occupants face during evacuation based on previous evacuation experience and what occupants were doing during the fire alarm.

Findings

The paper has identified the challenges and the factors that affect occupants’ decision during fire emergency in high-rise residential buildings. It is clear from the findings that occupants have limited knowledge and skills on how to deal with fire emergencies. Occupants tend to depend on other evacuation routes. Occupants tend to ignore the fire alarm and usually they investigate if it is true or false.

Originality/value

The paper provides the knowledge and findings of occupants during fire emergency to fire engineers, facility managers, owners, and other professionals to assist during the design phase, and modify designs based on this findings of this research.

Abstract

Purpose

The purpose of this paper is to present the findings of a theoretical calculation for the emergency evacuation of an auditorium facility managed by a university in Saudi Arabia.

Design/methodology/approach

The authors reviewed the published literature to identify the sources of fire incidence, guidelines for means of escape in assembly occupancies and human behavior in fire emergencies. The theoretical method of the SFPE handbook to estimate the required evacuation time was subsequently applied to a case study of an auditorium facility managed by a university located in Saudi Arabia. Finally, the authors developed recommendations for the performance-based fire safety evacuation of the auditorium facility under review.

Findings

The study showed that a total of 6 minutes 39 seconds is needed to evacuate the whole auditorium. However, reviewed literature for assembly occupancies requires between 4 minutes 30 seconds and 6 minutes 24 seconds for total evacuation. Though, the calculated evacuation time is close to generally acceptable limits. It was noted that overcrowding and bottlenecks may be formed in some of the exit routes.

Originality/value

This paper will stimulate and increase research and industry concern for performance-based design of assembly-type facilities. This will be of significant value to designers, engineers, facilities managers, and owners in ensuring the safety of occupants in assembly-type facilities.

Abstract

A review of research, interviews and experiments at an IKEA building are presented with results that could affect the planning and real time management. Subjects had to choose between a normal exit and an emergency exit in different conditions. The results show that the majority of subjects choose the normal exit even if the distance is double compared to the emergency exit. The only exception is when the emergency exit is open and it is possible to see the daylight outside. Findings show that a ring signal is often misunderstood but a spoken message is understandable.

Abstract

Purpose

Following the terrorist attack on the New York World Trade Center in 2001, this paper seeks to investigate the design features that would enhance the safety of tall buildings.

Design/methodology/approach

Using a questionnaire, data have been collected via e‐mails and by post from architects and civil engineers (AEs) in Singapore. Structured interviews were conducted with public authorities.

Findings

The results show that AEs perceive tall buildings to be generally safe in terms of structural design, fire safety features and means of escape. The results also show that AEs confirm the need to improve the safety of tall buildings further, are making an effort to address the heightened safety concern, will give full support to initiatives to address heightened safety concerns, will agree to conduct risk assessment during the design phase and will welcome a performance‐based design code. AEs do not agree that buildings should be designed to withstand hydrocarbon fires or aircraft attacks. The survey results further reveal that the four most effective methods to improve the safety of tall buildings are providing exit signs with lighting at floor levels, a separate design code for super tall buildings, providing fire refuge and rescue floors, and the decentralization of fire systems.

Originality/value

The importance of this paper is that it investigates the safety features and measures that can shed some light on enhancing the safety of tall buildings. The findings may be used by building authorities to formulate future measures and codes to better enhance the safety of tall buildings. Based on the findings, further research on each feasible method of improving the safety of tall buildings may be undertaken.

Abstract

Purpose

This paper aims to assess the level of occupants’ satisfaction, comparing older and newer on-campus accommodation buildings in Sydney, Australia, aiming to identify their comfort factors deficiencies in terms of design and construction solutions/strategies (e.g. spatial arrangements, materials, thermal comfort).

Design/methodology/approach

A post occupancy evaluation survey was used to assess the occupant satisfaction with three on-campus accommodation buildings in The University of New South Wales (UNSW) Sydney. One of the selected buildings is an older building opened for occupation in 1996, and the other two are more recent on campus accommodations buildings. The survey included 11 post occupancy evaluation elements identified through literature review which were categorised into three dimensions: technical, functional and behavioural.

Findings

The results show that the satisfaction levels with thermal and acoustic comfort were below standards for both older and newer buildings. In addition, the older building used in this study was rated low in terms of: indoor air quality, lighting, maintenance and management, vertical transportation facility, room layout and furniture quality, building layout and aesthetics and level of privacy. Such factors related to both functional and behavioural dimensions were of greater satisfaction in newer buildings.

Practical implications

Findings suggest the high priority of strategies that address and improve the thermal and acoustic comfort of older and newer on-campus accommodation buildings if the intention is to enhance students’ satisfaction, especially considering the impact that these facilities have on students’ performance. Thermal performance in different seasons and adaptive thermal comfort activities should be considered in the design of new on-campus accommodation buildings and the retrofit of existing old buildings.

Originality/value

On-campus accommodation is an important facility that supports student learning outcomes and helps students adapt in a new learning environment. A post occupancy evaluation study to assess the adequacy of this facility is still lacking because previous studies have generally focussed on class rooms and work spaces in the education sector. This research compares the user satisfaction of older and newer on-campus accommodation buildings in Australia, to highlight deficiencies and areas for improvement in the design of existing and future buildings.

Abstract

Purpose

The purpose of this paper is to check and fill the gap between the existing fire safety regulations for newly built tall buildings in Bulgaria and those in areas with rapid economic growth in the Asia-Oceania regions like the Hong Kong Special Administrative Region and Mainland China, by making comparative analysis and identifying good practices. The main focus is on the development of fire safety designs, facilities and management, which shall be recognized as essential parts of facility management in tall buildings.

Design/methodology/approach

Bulgarian regulations are analyzed and then compared with those in the Hong Kong Special Administrative Region and Mainland China. In addition, the scientific aspect of fire load density in the fire codes is discussed. The possibility of implementing a fire engineering approach to supplement prescriptive codes is outlined. The essential roles of fire safety management and fire safety culture are presented.

Findings

Key points and recommendations that are worthy for discussion about incorporation in the Bulgarian tall buildings fire safety requirements are upgraded requirements for fire load density, detection and sprinkler systems in tall residential buildings, refuge floors, ventilation/air conditioning control systems, full-scale burning tests and fire engineering approach. The importance of fire safety management is emphasized as a main, key component in facility management.

Originality/value

The research is the first study focusing on implementation of additional and specific fire safety regulations for tall buildings in Bulgaria.
