The objective of optimization is to present a design process that minimizes the total material consumption while satisfying current codes and specifications. In the research an optimization formulation for RC shear wall structures is proposed. And based on conceptual design methodology, an optimization process is investigated. Then optimal design techniques and specific explanations are introduced for residential buildings with shear wall structure, especially for that with a rectangular layout. An example of 30-story building is presented to illustrate the effectiveness of the proposed optimal design process. Furthermore, the influence of aspect ratio on the concrete consumption and the steel consumption of the superstructure are analyzed for this typical RC shear wall structure; and their relations are obtained by regressive analysis. Finally, the optimal material consumption is suggested for the residential building with RC shear wall structure and with rectangular layout. The relation and the data suggested can be used for guiding the design of similar RC shear wall structures.

Purpose: Recently, high-rise buildings are popular in korea due to high rate of land usage and cost performance in urban area. However, high-rise building causes several problems such as safety issues, cooling/heating load, stack effect, disaster prevention etc. The stack effect is one of the representative problems. Even though there are many researches on stack effect, there are few studies on design guideline considering local condition. Method: This study focuses on the change of pressure distribution according to the design factors which affects the airflow in high-rise residential buildings by simulation analysis. In this study, city, building floor, stairwell door leakage area, elevator door leakage area and changes of layout were considered ad the design factor. Result: The simulation results indicate that building height and ambient air temperature are significant design factor for stack effect.

The purpose of this study was to find out awareness of the environment-friendly planning elements for residential unit space among practitioners. The respondents in this questionnaire survey were 140 practitioners in architecture and interior design field. The major findings of this study were as follows; most of the respondents were aware of the impact of indoor built environment on residents' wellness. In addition, the survey respondents viewed that the factors for planning environment-friendly high-rise apartments were represented by gardening and energy-saving while their perception on the concept excluded comprehensive components affecting residents' life quality. Over 50% of respondents had an experience of applying environment-friendly planning elements in their works, and high frequency appeared on the general planning elements which had been applied special awareness as pro-environmental features. The respondents considered environment-friendly planning elements as important. Specially, space planning and system were considered more likely important in interior design field. In application of environment-friendly planning elements, cost, lack of consumers' awareness of and underdevelopment of environment-friendly materials were of concern. Therefore, the consumer's cognition needs to be improved for wide application about environment-friendly planning element, and then consumers are willing to pay additional construction cost of environment-friendly apartments. At the same time, the current practice that housing developers pass the additional cost on to residents needs to be changed. Then, the quality of life in high-rise residential settings can be improved. More importantly, the exchange and development of the reliable information on environment-friendly planning elements need to be made, and technical support and long-term policy for the development are required. This research showed current status of knowledge and practice in sustainable planning of unit apartment and proved basic information for future direction.

This study aims to find the conservation and regeneration plan in terms of preserving and utilizing old wooden houses, regenerating existing buildings, and developing idle land for old dwellings located outside the southern gate of Cheongju, Korea. In the preservation and utilization of old houses, three places in the block where wooden houses clustered are created as conservation houses, and are conversed as cafes, workspaces, and homestays along with the preservation of individual houses. In the regeneration of existing buildings, the street landscape was improved through extension and renovation, new construction after demolition, and exterior renovation for one or two-story buildings facing the roadside. In the development of idle land, it reflects the layout method and open yard space corresponding to the path and orientation of the old house, and the mass was varied and segmented to resolve the medium scale. Accordingly, considering the context, landscape, and environmental aspects of the historical downtown, the development of old dwellings in downtown should shift from a uniform high-rise apartment project-oriented approach to a gradual and continuous regeneration direction.

Landmarks like high-rise building are one of the important elements for the enhancement of city identity and provides the hierarchy of city streets, playing a central and symbolic role in cities. Research on physical attribute of landmarks, such as height, distance, location and shape, which are suitable for a city scale, can help a city create a distinct image and maintain comprehensible structure. To achieve this purpose, it is necessary to understand the spatial and cognitive characteristics of a landmark for the establishment and management of it. The results of this study can be summarized as follows: 1. The level of representativeness of a landmark increases in proportion to the degree of cognitive intensity on it. The relation between representativeness and cognitive intensity can be explained as the log-function as follows: Log(the number of people who respond "It has representativeness")=$-1.2579+1.5908{\times}$(cognitive intensity); 2. There are a few differences based on the attributes of respondents: while gender has no distinct influence, residential period and age show statistically meaningful influence on cognitive intensity of a vertical landmark Cognitive intensity of an individual landmarks especially, differs according to the class of main users. Because of frequent changes in occupation or employment, respondents consider the distance from a residential area more important than the distance from a working area in evaluating cognitive intensity of landmarks; 3. landmark can be classified into two kinds: a district landmark and an urban landmark A district landmark is closely connected with physical attributes of the landmark itself, such as distance, size and height. An urban landmark is mainly related to cognitive attributes such as the image and identity of a city as a whole. As a result, the landmark analysis data in this research provides spatial order and identity in a city. It is difficult to establish and reinforce the image of a city as a single element ike a landmark. However, withy steady follow-up research, this study could be seen as a systematic and logical model to improve urban landscape and image.

This proposed simulation-based design study is based on the design of residential high-rise buildings in South-Korea. the purpose of this study is to evaluate the amount of daylighting performance passing through building glazing according to sky conditions, orientation of windows and each space of Apartment buildings. The clear sky includes sunshine and is intense and brighter at the horizon than at the zenith, except in the area around the sun. Daylight received within a building is directly dependent upon the sun's position and the atmospheric conditions. Orientation of the building generally used to refer to solar orientation which is the siting of building with respect to solar access. Although any building will have different orientations for its different sides, the orientation can refer to a particular room, or to the most important facade of the building. north-facing windows receive twice the winter sun than east and west facing windows, allowing light and warmth into the home. They can be easily shaded from the high summer sun to help keep the house cool. Ideally, the glazing area should be between 10-25% of the floor area of the room. This paper was calculated by a Desktop Radiance program. The space dimensions were based on a unit module of real constructed apartment having divided into five sections such as living room, room1, room2, room3 and kitchen.
