There were increasing concerns on the possibility and suitability of using elevators for high-rise building evacuation because, through the improvement of the elevator system, the self-evacuation ability of age people is promoted as much as possible in the process of an emergency evacuation. The combined evacuation using both elevators and stairs was put into discussion. However, there was no empirical evidence and numerical simulation on emergency evacuation using both elevators and staircases for aging people in high-rise nursing homes. Therefore, using one case study, this paper simulated the emergency evacuation in a high-rise nursing home using variables such as the distribution of the elderly with different physical conditions, the proportion of the elderly in different physical conditions, the number of the elderly, the number of floors, the number of elevators used, and the priority of the elevator floor. By simulating the evacuation process in various scenarios, the general distribution strategy of high-rise nursing home and the optimal use of the elevator-stair combination during the emergency evacuation were developed. Results show that the elevator-stair combination of evacuation is more effective than using elevators or stairs alone. Increasing the number and speed of elevators can reduce evacuation time. Categorizing elderly people on each floor according to their physical conditions could reduce the evacuation time than randomly distributing them.

Emergency evacuation is an important issue in public security. To make a considerate plan, various situations are presented including blocking the accident area and letting the emergency access path available. In order to offer dynamic evacuation routes due to different circumstances, a multistory building evacuation model is proposed. Firstly, to analyse the patency of the building, an evacuation formula is applied after binary processing. The function of evacuation time and some other parameters is given by means of regression analysis. Secondly, the cellular automata (CA) algorithm was applied to illustrate the effect of the bottleneck. The response of evacuation time could be approximately optimized through calculating time step of the CA simulation. Finally, the value of maximum evacuation population density could be determined according to the analysis of CA simulation results, which was related to the switch state of the emergency channel. The emergency evacuation model was simulated by using the Louvre museum as an example. The results of the simulation presented some feasible evacuation routes in all kinds of situations. Furthermore, the functional relationship would also be given among evacuation time with the diversity of tourists, pedestrian density, and width of exits. It can give a different perspective that the multistory building evacuation model shows excellent adaptability to different circumstances.

Title: Living Arrangement Pattern Nursing Home Occupants Based Activities and BehaviorPhysical comfort in a building can give an effect to the psychological inhabitans. In the design of nursing homes, where the residents are elderly, certainly they have a different physical comfort with a younger people. The degenerative disease on elderly cause the need for special attention in architecture, especially on safety and comfort. Currently the nursing homes, mostly do not noticed it well, so still discovered lots of the elderlies got an accident and depressed in a nursing home. This research purpose to know the relationship between the aspects of both comfort and safety for elderly in nursing home that can make the elderly feel comfortable and happy living in their residence. The methods of this research is as follows: first, understand the criteria of elderly in related literatures and observations regarding to the elderly and other related literatures that subscribe with safety and comfort. Second, the literatures study were used to analyze the case study such as Nursing Home Wisma Mulia (Jakarta), Nursing Home Senjarawi (Bandung), and Nursing Home Muara Kasih (Bogor). The results of analysis from the case studies based on the literature, produce an architectural design criteria for the review occupancy elderly. The results of this research concluded that the design of the comfortable and safe against risk of any accident that may occur to the elderly, provided a circulation which can be passes by two wheelchairs at once and freeway, provided handrail in the circulation, provided ramp in any difference level of floor, and using a contrast color but dominant in light and warm color. The other considerations are the availability nostalgic room, playroom for children and the other facility that make the frequency of their families, visiting more often.Keywords: Elderly , safety , comfort , nursing homes.

Physical comfort in a building can give an effect to the psychological inhabitans. In the design of nursing homes, where the residents are elderly, certainly they have a different physical comfort with a younger people. The degenerative disease on elderly cause the need for special attention in architecture, especially on safety and comfort.

The special act for the management of disasters in super high-rise buildings and complex buildings with underground connections included the installation of a certain area of evacuation safety layer within 30 floors for high-rise buildings. However, for high-rise buildings with 30 stories or less, there is no separate regulation for evacuation safety floors. For high-rise apartments with less than 30 stories that do not have regulations for evacuation safety floors, an underground parking lot can be designated as a refuge shelter-in-place (SIP). This study aims to provide an optimal evacuation plan for evacuation simulations in high-rise apartments. This plan will ensure that the occupants are safely evacuated to the refuge SIP within a minimum timeframe. Evacuation simulations are conducted to establish an optimum evacuation plan. This is because there could be delays in the evacuation time as well as human casualties when evacuating to a SIP using stairs for the elderly and the disabled. Therefore, the elderly and the disabled use elevators to evacuate. The scenarios in this study were simulated on the basis of the number of occupants, the speed of the elevator, the number of evacuation stairs as SIP escape routes, and whether the elevator was used.

AbstractIntroductionEvacuation of the World Trade Center (WTC) twin towers and surrounding buildings damaged in the September 11, 2001 attacks provides a unique opportunity to study factors that affect emergency evacuation of high rise buildings.ProblemThe goal of this study is to understand the extent to which structural and behavioral barriers and limitations of personal mobility affected evacuation by occupants of affected buildings on September 11, 2001.MethodsThis analysis included 5,023 civilian, adult enrollees within the World Trade Center Health Registry who evacuated the two World Trade Center towers and over 30 other Lower Manhattan buildings that were damaged or destroyed on September 11, 2001. Multinomial logistic regression was used to predict total evacuation time (<30 to ≤60 minutes, >1 hour to <2 hours relative to ≤30 minutes) in relation to number of infrastructure barriers and number of behavioral barriers, adjusted for demographic and other factors.ResultsA higher percentage of evacuees reported encountering at least one behavioral barrier (84.9%) than reported at least one infrastructure barrier (51.9%). This pattern was consistent in all buildings except WTC 1, the first building attacked, where >90% of evacuees reported encountering both types of barriers. Smoke and poor lighting were the most frequently-reported structural barriers. Extreme crowding, lack of communication with officials, and being surrounded by panicked crowds were the most frequently-reported behavioral barriers. Multivariate analyses showed evacuation time to be independently associated with the number of each type of barrier as well as gender (longer times for women), but not with the floor from which evacuation began. After adjustment, personal mobility impairment was not associated with increased evacuation time.ConclusionBecause most high-rise buildings have unique designs, infrastructure factors tend to be less predictable than behavioral factors, but both need to be considered in developing emergency evacuation plans in order to decrease evacuation time and, consequently, risk of injury and death during an emergency evacuation.GroegerJL, StellmanSD, KravittA, BrackbillRM.

PurposeIn 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/approachThis 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.FindingsFindings 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/valueThis 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.

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.
