As a tool to analyze the visual characteristics of space, the visibility graph has advantages such as being free from 'arbitrary segmentation' issue and an ability to make a fine analysis on the open plan. Nevertheless, the number of unit spaces of a visibility graph is too many to investigate individual units and division of the subject area is difficult due to continuous change of visual characteristics. In this study, we analyze visual characteristics of a unit space in relations to the other unit spaces by clustering analysis. By clustering of similar unit spaces, we can describe homogeneous groups of unit spaces and analyze the configuration of a space. Finally we examine this analysis method by applying on an architectural space.

현행 철도설계지침은 철도역사 여객시설의 계획 목표로 시설물별 설계 서비스수준을 제시하고, 규모계획 기준의 면적 산정식에 Fruin의 서비스수준(LOS) 이론을 적용하고 있다. 그러나 서비스수준을 근거로 한 여객시설 계획은 보행 및 대기공간에 한정된다.본 논문은 철도역사 여객시설의 서비스수준을 다면적으로 평가하기 위한 정량적 평가지표 항목을 제시한다. 여객 서비스에 필요한 다양한 세부시설을 분류하고, 각 세부시설을 대상으로 이용객이 느끼는 편의성에 영향을 줄 수 있는 요인을 분석하여 평가지표 항목을 도출한다. The current design guideline of railway station proposes LOS of each facility for planning passenger facilities in a railway station. And it is applied Fruin’s LOS theory to area calculation formula in planning capacity and size. But plan a passenger facilities based on LOS limited to pedestrian and waiting space. This study proposes a quantitative evaluation index for evaluating LOS for a railway station passenger facility in a multi-faced way. It classifies various detailed facilities required passenger services, and it derives the evaluation index from analyzing the factors that may affect the passenger’s convenience level in various facilities within a railway station.

The purpose of this study is to develop a methodology to track the behavior of pedestrians in railway station passenger facilities by utilizing video clips. In order to provide comfortable and user-centered passenger facilities, an understanding of the current behavior of passengers should be prioritized through pedestrian tracking surveys. However, because railway stations become congested in a short amount of time, direct observation in situ with a limited number of researchers is difficult. Thus, utilizing video equipments was developed as a methodology for tracking the behavior of pedestrians in railway passenger facilities. This study developed a method for collecting pedestrian behavior data by utilizing video equipments and tracking pedestrian circulation. The pedestrian tracking survey was conducted using this method and applied in an actual railway station. The derived results identify the use patterns and changes in the railway station and reveal the differences with the current standard.

The purpose of this research is to construct a classification system of biological information so that it can be applied to biomimicry architectural research. It is both uneconomical and time consuming for architectural researchers to spend time searching and studying principles of organisms. In this study, we suggested a classification system which includes biological information and can be used as a guide for architectural researchers attempting to research biomimicry architecture. Basic principles were extracted from architectural planning elements and biological information. Architectural experts matched biological principles to relevant architectural principles. Based on the architectural and biological principle correspondence table, group analysis was conducted. Biological principles were classified into 6 parts: air, structure/material, habitat, water/circulation, shape, and energy. This classification of biological principles corresponds to 6 architectural principles: ventilation, natural material, insulation, water resource, awning, and lighting/solar heat. According to the results of this research, specific classification groups may appear as biometric information increase through further research.

The purpose of this study is to develop an algorithm that includes the effect of the physical surroundings in the evaluation of parametric exterior louver designs. The algorithm assesses the yearly thermal performance of an exterior louver design using the weather data from Typical Meteorological Year and the solar position from DIVA for Rhino. As the algorithm calculates direct solar gain of the given surface, it considers the effect of the physical elements around the site. The algorithm compares the hourly solar gain on the given surface under the effect of the louver design with Best Case Scenario. The Best-Case Scenario is a condition that maximizes solar heat gain in the heating season and that minimizes solar heat gain in the cooling season. The louver design gets a score that is the sum of the differences of hourly direct solar radiation with the best-case scenario. The paper presents a case study that uses the algorithm to evaluate the existing louvers of the two curtain wall office buildings in Seoul, Korea. It evaluates the existing louvers in two different settings; with the surrounding buildings and without the surrounding buildings. The result reveals that the inclusion of the physical surroundings create more accurate result and that the physical surroundings create different conditions even within the same surface. Therefore, the louver design should be custom-designed according to the different surrounding conditions.
