The purpose of this research is to analyze the publicity of the private open space of high-rise office buildings in seoul. The contents of this research consist of two main parts. The first part is to classify the personal behavior's characteristics and to investigate the user's satisfaction of the publicity in the private open space through the case study of samples in seoul. The second part is to analyze the correlations between the personal behavior's characteristics and the user's satisfaction of the publicity in the private open space of high-rise office buildings. In conclusion, this research will contribute to establish the planning methods of the private open space of high-rise office buildings and to promote the quality of urban residential environment in Korea.

This paper proposes a framework for understanding the energy consumption differences between tall and low-rise buildings. Energy usage data from 706 office buildings in New York illustrates expected correlations from the framework. Notable correlations include: taller buildings tend to use more energy until a plateau at 30~39 floors; tall buildings in Manhattan use 20% more energy than low-rise buildings in Manhattan, while tall buildings outside Manhattan use 4% more energy than low-rise buildings outside Manhattan. Additional correlations are discussed, among which is the trend that the Energy Star program in New York City assigns higher ratings to tall buildings with higher EUIs than low-rise buildings with the same EUI. Since Energy Star is based on regressions of existing buildings, the Energy Star ratings suggest taller buildings have higher EUIs than shorter buildings, which is confirmed by the New York City energy benchmarking data.

The greenhouse effect caused by human activities is becoming increasingly serious. The building industry, which is directly related with carbon emissions, has the responsibility and potentiality to reduce carbon emissions. Recently, Chinese and foreign academics have achieved some research results with respect to building carbon emissions. This paper tries to examine these issues in the context of climate conditions in the Shanghai area. Based on the typical floor plans of high-rise office buildings, analysis was performed via software simulation and data analysis; the paper explores the relationship between different design methods of typical floor plans and carbon emissions. The objective is to deliver results beneficial to typical floor-design methods with respect to the reduction of carbon emissions, so as to provide a reference for architects.

The focus of this study is that spacial, material, functional, cubical reasons are visually expressed on high-rise office Architecture in Korea according to the period of their completion. Office buildings are analyzed in three of exterior composition : Lower, Middle, Top part of the Building, Comparing the whole composition of the Building, forty-five types of compositions are extracted ; expression of formal, material, structural, functional Decoration which show the tendencies of Korean office buildings.

Recently, may high-rise buildings have been constructed, and will be constructed so that concerns about high-rise buildings have increased. We need to develop energy saving techniques immediately because the high-rise buildings consume a lot of energy. The most of effective energy saving method is the application of the efficient lighting designs and fixtures. The purpose of this study is to analyze the trend of lighting design, fixture and control system in Korea and it can be used the lighting application guide-line for the high-rise buildings.

The conflict between indoor environmental quality and energy consumption has become an unneglectable problem for highrise office buildings, where occupants' productivity is highly affected by their working environment. An effective Façade, therefore, should play the role of an active building skin by adapting to the ever-changing external environment and internal requirements. This paper explores the energy-saving and indoor environment-improving potential of a phase-change material (PCM) integrated Façade. Building performance simulations, combined with parametric study and sensitivity analysis, are adopted in this research. The result quantifies the potential of a PCM-integrated Façade with different configurations and PCM properties, taking as an example a south-oriented typical office room in Shanghai. It is found that a melting temperature of around $22^{\circ}C$ for the PCM layer is optimal. Compared to a conventional Façade, a PCM-integrated Façade effectively reduces total energy use, peak heating/cooling load, and operative temperature fluctuation during the periods of May-July and November-December.

This paper introduces the current status of high-rise building design in Japan, with reference to some recent projects. Firstly, the design approval system and procedures for high-rise buildings and structures in Japan are introduced. Then, performance-based wind-resistant design of a 300 m-high building, Abeno Harukas, is introduced, where building configuration, superstructure systems and various damping devices are sophisticatedly integrated to ensure a higher level of safety and comfort against wind actions. Next, design of a 213 m-high building is introduced with special attention to habitability against the wind-induced horizontal motion. Finally, performance-based wind-resistant design of a 634 m-high tower, Tokyo Sky Tree, is introduced. For this structure, the core column system was adopted to satisfy the strict design requirements due to the severest level of seismic excitations and wind actions.

The purpose of structural health monitoring is to evaluate structural behavior due to various external loads through installation of appropriate measurement. Accordingly, a guideline for monitoring standards is necessary to evaluate the safety and performance of a structure. This paper introduces preliminary design of SHM for high-rise buildings, which is the stage creating a guideline. As for preliminary design of SHM, first step is to calculate the displacement and member force through structural analysis. After that, limitations or qualifications are proposed for management. Secondly, based on the results from first step, issues related monitoring such as monitoring method, measurement type, or installation location are determined. This method leads building managers to reasonably define the structural safety over the whole life cycle. Furthermore, this experience contributes to development of SHM forward and it is expected to be useful for other types of structures as well such as spatial structures or irregular buildings.

Based on past experiences of natural disasters and fires in Japan, it is stipulated by law that fire-resistant buildings larger than a certain size should be unique in the world. Recent interest in global environmental issues has led to the active introduction of wooden buildings also in Japan, and it is expected that wooden buildings will become larger and higher in size. This paper introduces the background of the development of fire-resistant laminated timber with a "Self-Charring-Stop layer", the contents of this development including other related developments, and the application of these technologies. In addition, towards the realization of much larger and higher buildings in the future, the current problems and issues to be solved are set and the necessity of the future technological development is described. Finally, a conceptual model of wooden high-rise building is proposed, which will be able to be constructed in 2025 by the further technological development.
