This study aims to identify the effect of the occupant density, application of the evacuation delay time, and the degree of opening of the fire doors in the household, parameters that are used in the performance-based design of the officetels of a residential structure, on the evaluation of evacuation safety and to suggest realistic alternatives. To this end, a preliminary survey was conducted on the number and ratio of residential officetels among the performance-based design targets in Gwangju Metropolitan City, which were implemented up to December 2020. Following this, two representative examples were selected, and for each type, an occupant density of 9.3 m2/person and 18.6 m2/person and an evacuation delay time of W1 and W2 were applied. In addition, for the degree of opening of the fire doors, full opening, 1/4 opening, and leakage gap were applied. With these conditions, the evaluation of evacuation safety was performed for 32 cases. Results of the evaluation showed that evacuation safety was secured in all cases for an occupant density of 18.6 m2/person, an evacuation delay time of W2, and the application of a leakage gap to the opening of the fire door. Therefore, using the above mentioned three parameters for the performance-based design of officetels of residential structures, we have proposed a more realistic design method in this study.

In this paper, the application of evacuation delay time (Cognition time + initiation time) and examine the degree of opening of fire doors in households for evaluating evacuation safety and suggest a realistic alternative. In order to proceed with this study, first of all, the preliminary investigation on evacuation safety evacuation of residential-type buildings (Apartment, urban living houses, etc.) among the performance-oriented design targets of Gwangju Metropolitan City, which was implemented until June 2018. Then, for the two representative types that are commonly used among the previously surveyed buildings, evacuation delay time is applied to W1, W2, and respectively simulating the opening of the doors is applied to th full open, 1/4 open, the leakage gap and evacuation safety evaluation was performed. As a result of evaluating evacuation safety was found that it is difficult to secure evacuation safety regardless of evacuation delay time W1 and W2 when the fire door is fully open and 1/4 open, Only when the leakage gap is applied evacuation safety was ensured even if evacuation delay time W2 was applied. Therefore, when a residential building is subject to performance-oriented design, evaluating the application of W2 rather than W1 is considered for evacuation delay time to reflect concern about privacy infringement due to CCTV installation, etc. In order to secure the Smoke blocking performance of the fire door and to improve the performance-oriented design, I would like to propose to consider the method of applying a leak gap to the degree of opening of the fire door. Through this, it is expected that the performance-oriented design will be a step further by performing evacuation safety evaluation with more realistic data.

Evacuation System

Recently, a performance-based design of a fire protection facility has been proposed that significantly contributes to the construction of safe and reliable buildings. Improving the performance of the fire protection facility will enable protection of the public along with the infrastructure. Designs focusing on the fire protection performance generally add or modify architectural aspects through fire and evacuation simulations. However, a secure evacuation system aided with CCTVs has rarely been considered as an active system. Particularly for apartments, it is very difficult to assure evacuation safety without using an active system in fire and evacuation simulations with the front door of the burning room open. Safety can be achieved by combining a passive system with an active system, on the basis that the building premises has the foundation of a passive system. The regulation on the evacuation delay time in the nation was brought in effect through the SFPE paper but was deleted since the data reliability was insufficient. Therefore, the aim of the present study is to analyze the operation of a fire protection facility required to ensure safety by planning multiple simulations of a fire and evacuation system. An apartment has been considered as an example to design the foundation for a standard evacuation safety system. An active system is applied to execute fire and evacuation simulations, with focus on the fire protection performance.

Performance Based Design (PBD) is being developed as a more reasonable and flexible design method for a next generation of design method. To implement PBD, this paper presents a systematic approach (Bayesian method) for developing concrete material mixture design to satisfaction criterion level relationship. Satisfaction curves describe the probability of concrete reaching or exceeding different criterion level at specified levels of concrete material.

As a result of the impact of energy consumption, research on ultra-low energy, nearly zero-energy, and zero energy buildings has been conducted in China. However, the design of the nearly zero-energy building is flexible; the traditional architectural design method is not fully applicable to nearly zero-energy buildings. The paper proposed a performance-based design method based on overall energy consumption and progress for the nearly zero-energy building. The design process of the relevant cases was also analyzed. The factors of cold and heat sources, environment, and renewable energy were combined to make a comprehensive analysis to get the optimal scheme of the nearly zero-energy building in the case. In general, the performance-based design method has a certain guiding significance for the design of nearly zero-energy buildings and certainly promotes the expansion of the nearly zero-energy building industry in China.
