The purpose of the study is to plan efficient evacuation route for evacuating persons safely in emergency situations by analysing pedestrian flow in mixed-use buildings. The study has performed by the following approaches: initially, main circulation system and evacuation routes are investigated through four case studies. Second, pedestrian volumes are analyzed based on the outcome of the case study. Finally, the study develops evacuation route planning which is suitable for emergency situations by reviewing the connection between main circulation and evacuation routes. According to the study, the following conclusions were made: evacuation route planning is required to consider pedestrian density, building scale, and space characteristics. Also, the core plan should include evacuation staircases and E/V and the evacuation route need to be easily recognized.

The purpose of this study was to deduce implications for the improvement in subway station for crime prevention based on the comprehensive analysis of the results of crime data analysis, expert interview, and computer simulation. To deduce characteristics of architectural design affecting the risk of sex offenses, passenger data, architectural documents, and crime data of seventeen non-transfer stations which have similar circumstance characteristics were investigated. And for simulating how passengers move from platform to ticket gate in stations, the Simulex was used. The results showed that the higher sexual crime rate of the station is correlated with the place where the congestion and crowding occurs. In conclusion, the architectural design elements of subway station which cause the passenger congestion were summarized and measures of architectural design for crime prevention in subway station were suggested.

DOI : 10.5659/JAIK_PD.2015.31.11.23
This study is to analyse planning condition quantitatively by statistical method to improve the number of users, the rate of general users and user's satisfaction in open space of building site, and make it predictable these indicators of use evaluation and environmental mentality evaluation at the planning and designing stage. Also, it is to suggest design guidelines applicable to the planning of open space or the improvement of institutions by considering the planning conditions comprehensively for improving the indicators discussed separately. Comprehensive overview of the planning conditions to improve plural indicators shows that the important planning conditions are scale, relationship with the surroundings such as station or street, the shape of open space with a good accessibility from road, attached facility to provide the purpose of use or a comfortable seating area. In particular, as a representative planning condition to improve three indicators at the same time, relationships with the surroundings and shape of open space can be cited. The relationships with the surroundings is the evaluation index for convenience such as distance from subway stations or possibility of shortcuts. The shape of open space is the index explaining the relationship with pedestrian pathway, and it can be considered as evaluation index for urban public space on the extension of street.
A Study on Change of Residential Space Based on Maslow's Theory of Human Motivation - Focused on Korean Public Apartment from 1955 to 1990 -
Lee, Yoonseo ; You, Aram ; Kim, Kwang-Hyun ;
Journal of the architectural institute of Korea planning & design, volume 31, issue 11, 2015, Pages 31~38
DOI : 10.5659/JAIK_PD.2015.31.11.31
The purpose of this study is to draw residential space elements based on hierarchy of needs from Maslow's motivation theory, and to analyze residential space changes of Korean public apartment. This research selected 25 public apartment housings by data(Plan, Area and Price) availability and PIR value(3~6). PIR value is used to select similar level of housings. This research used literature review to draw residential space elements and used descriptive analysis to analyze residential space changes. Residential space elements based on hierarchy of needs are as follows. At least 1 room, form of kitchen and relationship between kitchen & bath room are related with physiological needs. Second, structural safety, heating system, material and fire extinguishing facilities are related with needs of safety. Third, proportion & independency of living room, relationship between kitchen & living room and total area of house are related with needs of belongings. Fourth, number of rooms & bays, hierarchy of main room and openness of rooms are related with needs of self-esteem. Fifth, connectivity of private space with other spaces is related with needs of self-actualization. The results of analysis of residential space changes can be summarized as follows. First, Until '60s, needs of safety came before physiological needs in residential space. Second, rain-proof roof for needs of safety was introduced in 1955. Third, role of living room was uncertain in the early stage of introducing apartment in Korea. After then, proportion of living room increased till '90s, and decreased after '90s. Fourth, room to living room ratio steadily increased till '90s. Fifth, individual storage and balcony for self-actualization were planned only '50s.
A Direction of Urban Planning on the Waterfront for Public through Corresponding with Climate Change - A Case Study on the Design Competition in New York and Boston -
Jeon, Hee-Sung ; Lee, Kum-jin ;
Journal of the architectural institute of Korea planning & design, volume 31, issue 11, 2015, Pages 39~50
DOI : 10.5659/JAIK_PD.2015.31.11.39
This study was started to propose the direction of a waterfront city's continuous utilization based on safety and public good while being focused on the reaction to climate changes. While researches and facilities related to climate changes are increasing and many problems are occurring from natural disasters worldwide, the directly affected waterfront areas are only interpreted from the meaning of urban development. Thus, starting from the fact that a uniform waterfront development method is being repeated with a passive attitude, a direction of waterfront development to adapt and react to climate changes will be presented from an architectural viewpoint. Based on the awarded proposals of the waterfront city design for New York and Boston that suffered massive damage from Hurricane Sandy, public service equality and activation of local community were pursued and a waterfront planning method capable of maintaining the functionality and characteristics of a waterfront area while providing safety was reviewed through a waterfront space plan including living, commercial and public space addressing the climate changes. In addition, the flexible actions of waterfront areas upon disaster were discussed from the viewpoint of architecture and space. The analysis was performed by focusing on the infrastructure such as wetland and green zones, water space and waterfront space as the their symbolic meaning and history, institutional proposals etc. while taking the public space and buildings as the main factors. Then, the factors that can be applied on future waterfront areas were derived to explore the utility of waterfront cities upon abnormal climate.
An Analysis on the Implementation System and the Role of Participants in Demonstration Projects of Community-Design

'Community-Design' is the movement and the project which enhances residence area, mainly led by residents themselves. The project improves the feature of life by upgrading the living environment, not only physically reformed, but also continuously cared by residents, administration and experts. However, in the process of the project which accompanies a number of residents and groups, some problems are exposed; conflicts of opinions and confusion between each part of roles are caused, so sometimes the plan goes off on a tangent or communities are broken up. Thus, this study draw the exemplary promotion system and the roles of participants from some cases in the demonstration projects. The goal of this study is to suggest a standard model for applying to the future business of 'Community-Design' by verifying the suggested system. The scope of this study covers 'DaeHak-Dong in Ansan' case and urban residence and commerce area case among 'Making the Livable City'; a representative sample of the domestic business of 'Community Design'. The standard promotion system is divided into 'led by administration' and 'led by residents'. This study tests propriety from the cases of 'led by residents' based on the aim of 'Community Design'. In the process of the project, residents should try to play a leading role, and administration and expert should play a directly supporting role. Participants should maintain governance through lateral relationship with mutual intelligibility, and aim to have a complementary role with the proper participate time on each phase.

Environmental contamination has been a global issued problem and each country tries to make a solution for it. In South Korea, institutional solutions like Energy Consumption Certification has been issued and proposed to solve the environmental problem. However, it has been lack of solutions which consider architectural design method itself. After industrial revolution in 20th century, the façade design of contemporary architecture has been developed based on 'envelope' concept which is so different from the methods of design before. And achieving environment friendly is a global wide issue in these days. Accordingly, the substantive development for environmental problems in architectural design method, which is extension of present architectural theories are required. For this reason, this study focused on energy performance based façade design method for renovation projects which must be considered existing building situation and context. First of all, building facades of South Korean national universities which constructed through 1960's and 1970's are analyzed with the compositional design method. Second, the certain elements of façade's design properties are simulated to find differences of energy performance. Through this process we can see the correlation between façade element's design and energy performance. And not only the definite design method of energy performance based façade design but also design process that architects approach can be suggested.

It is difficult to select suitable residence for single household consumers in the existing housing market. Because the existing housing market is formed by housing providers and it does not reflect the characteristics and needs of the consumers. So, consumer-centered housing market need to be formed to reflecting the characteristics and requirements of the single household. This enables consumers to choose from a variety of suitable alternative housing. The purpose of this study is to support appropriate decision-making for single household consumers by representing the housing and residential environment in the prediction model. In this study, the main factors of change in the housing market and complex factors(independent variables) that affect the choice of the consumer's housing selection were analyzed. In addition, housing types and housing tenures(dependent variables) were selected to build a prediction model for single households.

Since aging is associated with physical, cognitive, and social limitations that affect functional capacity of individual, alternative housing options were sought by many researchers as well as housing industry. Barrier Free housing features can help older adults to cope with consequences of aging and to live more independently in their housing. The purpose of this study is to evaluate the preference of young adults and the elderly for accessible housing attributes in their housing choice by using conjoint method, whereby respondents ranked a specific combination of particular accessible features. Based on literature reviews, accessible attributes were identified and used for analysis. The accessible attributes are clear width, removal of level difference, vertical accessibility, grab bars, non-slippery floor materials, alarm device, controller for service, and cost. The result indicated how important each accessible attribute is according to individual differences including age, income, housing type, and ownership. The most apparent difference in preference between the younger and the elderly was cost aspects in associated with accessible features. Regardless of age, income, and housing type, the respondents rated cost more important in their housing choice decision compared to the other accessible features. The conjoint analysis revealed that accessible housing attributes were related to the socio-economic variables of residents and housing type. For a single house type, vertical accessibility (e.g. elevator installation) is important. The combination of accessible attributes of housing ranked by residents was suggested.
A Study on the Contemporary Architecture through M. Merleau-Ponty's Phenomenological 'Chiasme' - Focusing on the Architectural Revival Space -
Kim, Nam-Hyeon ; Chang, Yong-Soon ;
Journal of the architectural institute of Korea planning & design, volume 31, issue 11, 2015, Pages 103~110
DOI : 10.5659/JAIK_PD.2015.31.11.103
The approach of this study was to move away thinking and reasoning and visual-centered approach as the idea of contemporary architecture and to approach the person to experience the space and the construction of the relationship in terms of a variety of physical perception, through the analysis of Merleau Ponty's phenomenological chiasme, Away from the dichotomous framing, past and present, subject and object, entirety and part depending on the person to experience the space to find a possibility be interpreted in view of the experience. Therefore, base on the literature in the philosophy of Merleau Ponty's phenomenological ground. This is reflected in the architectural practice uses a revival space of contemporary architecture divided into ruins, mirrors, fragments by a framework of analysis and investigation of their properties and how to use that analysis and investigation of their properties and how to use that analysis.
A Study on the Location and Natural Environment of Eup-Settlements in Late Joseon Dynasty as Reflected in Mountain Range and Watershed - Focused on Suwon Hwaseong -
Kim, Byeong-Ju ;
Journal of the architectural institute of Korea planning & design, volume 31, issue 11, 2015, Pages 111~121
DOI : 10.5659/JAIK_PD.2015.31.11.111
This study, based on the Fengshui theory, explains the location and natural environment of Suwon Hwaseong in Joseon dynasty as reflected in mountain range and watershed. Feng-shui theory had been acted longtime as the location selection guide for traditional settlements and dwelling in East Asia. In the location of pre-modern city, Mountain range Yongmaek should be connected long. The way out of Water stream Sugu should be closed topography. But, Mountain range is not connected in Hwaseong, and the way out of Water stream is opened to outside. This is an important location and natural environment characteristic as 18th century's new city of Hwaseong.
A Study on Characteristics of the Airport Architecture from the viewpoint of 'Non-Place'
Jung, Hye-Jin ;
Journal of the architectural institute of Korea planning & design, volume 31, issue 11, 2015, Pages 123~132
DOI : 10.5659/JAIK_PD.2015.31.11.123
The aim of this study is to analyse spatial characteristics of the airport architecture focused on Marc
notion called 'Non-Place'. The airport architecture started as a place of the event in the suburbs as opposed to the residential place of the city from the beginning, and then it came to have a characteristic as a marginal place which connects local places as a node of the global network and exits between them at the same time, not belonging to a particular local place. In addition, the modern international hub airport architecture developed into the terminal complex that features a unique architectural typology as a architectural facility that spatializes the continuous flow of mobility, a combination of infrastructurization with flow-meditated parameter machine, and a traffic flow distribution device as well as a boarding connection medium. The airport architectural space is basically for handling and performing the procedures of 'flight'. In this sense, the airport architecture was established as a space for the purpose of passing movement and circulation, which means that the architectural spatialization process of airport architecture regards how to deal with the mobility and flow as key design elements. In addition, spatial system according to the change of flow in the linked identity are intermediated by various symbols and technologies that mediate space, users and communication between individuals and others. The airport architectural space directs the flow into a space of disorientation resulting from a huge scale and complex traffic flow system and consists of various media that provide information about the space and overall spatial environment, and users come to experience the spatial environment as a landscape image of the flow through visual communication with signs, which indicates the nature of non-place in that the experiential form of airport space is characterized by the abstraction through visualization.
A Study on the Ramp in Richard Meier's Architecture - on the basis of Flora Samuel's 'narrative path' -
Jeong, Jae-Hoon ; Kim, Hyon-Sob ;
Journal of the architectural institute of Korea planning & design, volume 31, issue 11, 2015, Pages 133~142
DOI : 10.5659/JAIK_PD.2015.31.11.133
Aiming at an investigation into ramps in Richard Meier's architecture, this paper analyzed five design examples - including the Frankfurt Museum for the Decorative Arts (1979-85) - on the basis of the 'narrative path' that Flora Samuel (2010) extracted from Le Corbusier's 'promenade architecturale'. As a result, this research clarified that the ramp as a key element to Meier's circulation system dramatizes our spatial experience within his buildings, and that it has two unique aspects of 'an elevation ramp' and 'a ramp hall'. These characteristics are meaningful since they show that Meier creatively developed the Corbusian precedent of ramp to match the contemporary context.

This study aims to identify problems which can be encountered in international urban development projects, especially in urban design process, and to propose the solutions to the problems. For this, surveys and interviews of experts who have performed international urban design projects were conducted. According to the surveys and interviews, the main problems in international urban design projects are the lack of basic information about the foreign country and the shortage of capital. To solve these problems, first, all the basic information which is essential for the projects has to be collected and managed by public sector, and provided to those who try to work on the projects at a proper time. Second, the public sector has to support the projects in terms of diplomacy, policy, and finance. Especially, it is very important for the public sector to fund the projects in order to make the projects successful.

Despite of the implementation of the various system, the number of sexual assault cases is increasing. These system are measure to control the sex offenders and it is difficult to control the sex offenders or the sexual assault victims. However, It is necessary to be factor derivation, for the environmental control is relatively easy. the sexual assault ratio, meanwhile, happen a lot in metropolitan cities. The purpose of this study was to analyze the factors on sex offense. sociodemographic and physical characteristics related sexual assault in previous researches was drawn and correlation and regression analysis was performed. The results show that the percentage of women vulnerable to sexual assault and the density of security lights had influence on the number of sexual assault cases per urbanization area. However, As the percentage of young adult population increase the number of sexual assault cases per urbanization area.

Lee, Myoung-Ju ; Lim, In-Hyok ; Hur, Da-Woon ;
Journal of the architectural institute of Korea planning & design, volume 31, issue 11, 2015, Pages 187~197
DOI : 10.5659/JAIK_PD.2015.31.11.187
We analyzed and compared the cooling/heating energy demand and cost of nine households of different positions in a passive house Apartment. To do this, the Passive House Planning Package(PHPP) was used on Building 102 of the Net Zero Energy Housing Complex located in Hagye-dong, Nowon-gu, Seoul, Korea. For the heating energy demand, it was analyzed that the middle floor and the first floor have the lowest and highest demands, respectively, and the highest demand was about twice as the lowest. On the same floor, the units in the middle had the lowest demand, while the units on the right and left of the building had little difference. For the cooling energy demand, the higher floors had higher demand, and the highest cooling energy demand was about 40% higher than the lowest. There was not much difference between the units on the same floor when it comes to cooling energy. By analyzing the cooling and heating costs of each household, we concluded that the household with the highest electricity bills payed about 50% higher cost than the one with the lowest bills.
Objective Energy Performance Assessment Using Data Envelopment Analysis (DEA)
Yoon, Seong-Hwan ; Park, Cheol-Soo ;
Journal of the architectural institute of Korea planning & design, volume 31, issue 11, 2015, Pages 199~209

Objective energy performance assessment of buildings is crucial for building stakeholders' rational decision making. One of the most popular building energy performance measures is Energy Use Intensity (EUI, kwh/m2.yr). This has been widely used since it is straightforward, simple and easy to understand. However, it has a severe drawback that it only shows the number of consumed energy per unit floor area and can't represent objective energy performance of a building. In other words, EUI does not deliver how well a building serves occupants and provides satisfactory services (e.g. thermal comfort). It is often misinterpreted in a way that the less EUI, the better building energy performance is. In this paper, a Data Envelopment Analysis (DEA) was applied to assess objective building energy performance. The DEA quantifies performance of a given system when multiple inputs and outputs are given. The DEA is a data-oriented and non-parametric method. Thus, it does not require any energy model and can consider multivariate inputs/outputs simultaneously. For the study, a number of virtual buildings were generated out of Monte-Carlo sampling and then simulated using EnergyPlus to derive a data set. Energy consumption was used as an input and building service levels (e.g. occupancy density [people/m2], operation time [hrs/yr], thermal comfort [PPD]) were used as outputs. It is shown that the DEA is a more objective and rational performance assessment method than the EUI, and can be a good alternative for building energy performance evaluation.

Weather data are indispensable for building energy simulation. Most weather stations measure only global solar radiation and thus, the global radiation is usually divided into direct and diffuse radiation based on solar models. The solar models being currently used are expressed in regression equations. Several studies have reported that the difference between measured direct/diffuse solar radiation and calculated direct/diffuse solar radiation out of the solar models is not negligible. This study aims to quantify the impact of the direct and diffuse split solar models on energy performance simulation. For this study, three popular solar models were chosen based on the literature review. And, a number of office buildings were simulated while changing several inputs relevant to solar load (e.g. SHGC, window-to-wall ratio, etc.). The sampling cases were made using LHS (Latin Hypercube Sampling), one of Monte Carlo techniques, and an energy simulation tool, EnergyPlus, was used. There is a significant difference between the measured weather data and the values of calculated direct and diffuse solar radiation. However, the difference between energy prediction by the measured weather data and energy prediction by solar models is not significant for large buildings. For small buildings, the difference in energy prediction is not negligible.
