Today 55 percent of the population in the world lives in urban areas which is expected to increase to 68 percent by the year 2050. In the cities, high-rise buildings as symbols of the modern cityscape are dominating the skylines, but the data to demonstrate their embodied energy and environmental impacts are scarce, compared to low- or mid-rise buildings. Reducing the embodied energy and environmental impacts of buildings is critical as about 42 percent of primary energy use and 39 percent of the global greenhouse gas (GHG) emissions come from the building sector. However, it is an overlooked area in embodied energy and environmental impacts of high-rise buildings. Life cycle assessment (LCA) is a widely used tool to quantify the embodied energy and environmental impacts of the building sector. LCA combined with Building Information Modeling (BIM) can simplify data acquisition of the building as well as provide both tools with feedback. Several studies recognize that the integration of BIM and LCA can simplify data acquisition of the building as well as provide tools with feedback. This article provides an overview of literature on BIM-based of embodied energy and environmental impacts of high-rise buildings. It also compares with different LCA methodologies. Finally, major strategies to reduce embodied energy and environmental impacts of high-rise buildings, research limitations and trends in the field are covered.

One of the major differences of Korean residential building compared with other countries is a rigid diaphragm of a floor due to the panel heating system. An increment of a gravity floor load might cause vibration problem when the composite floor system is introduced to the panel heating system. Since the noise criteria of a residential building is lower than that of an office building, the development of a noise absorbing system should be preceded. The response evaluation was performed for the finished floor, that is with panel heating and noise absorbing system. The natural frequency was obtained both from an experimental study and an analytical study. An appropriate vibration condition of a floor with panel heating and noise absorbing systems was evaluated from this study.

The present study aimed to find a way to create forms that can simultaneously meet several architectural requirements by applying generative design methods specifically focused on cellular automata. In other words, it is tried to find various forms of architecture that all have common features. Because of the useful features of cellular automata, we decided to use it to generate various forms, but make a relation between the discrete nature of cellular automata and the continuous nature of architecture, was the major problem of our project. To achieve this goal, three consecutive stages were designed. In the first stage, independent variables including the location of the building, the height of the building, and the building area were considered as the inputs of the model. In the second stage, after locating the building, the building's main shell was designed as a hidden geometry for the cellular automata and then the cellular automata were determined based on this shell. The main result of this research is establishing a logical relationship between the discrete geometry of the cellular automata and the continuous search space such that it creates various optimized forms. Although we specify the site plan of this project at Iran-Tehran, this research can be generalized to various design sites as well as different projects, allowing the architectsto alter the cell dimensions, cell density, etc., based on their opinion and project needs.

The unity of korean peninsula have traditionally been established as major policy in korea government. Present government also set Trust Process on the Korean Peninsula as national high-level strategies for unity, and construction field related directly to living of north korean as major industry which would be implemented in early stage. Deterioration level of architectural facilities in north korea is known as very high, so a huge budget would be required to improve aging architectural facilities for stability of social and living of north korean. Therefore the purpose of this study deduct financing plan for improving aging architectural facilities in north korea and selection of optimal alternative securing effectiveness. The results of this study could be utilized as preliminary data for establishment of master plan and policy for improving deteriorated facilities in situation of united korean peninsula.

This study aims to uncover the problems that are embedded on the detailed design processes of the major domestic EPC companies. To set the research frame, previous studies were analyzed and interviews were conducted for the industry experts. To draw fundamental factors that may affect on the effectiveness of detailed design processes, questionnaire surveys were conducted to those who involved in detailed design and who have design experiences. Analysis results indicated that there are rooms for improvement on the detailed design processes. This study will be a guidance for future researches that must be followed.

The major goal of this study is to develop an index that can evaluate the quality of the appropriate network in a series of projections that analyze, design, and then build a network. The existing software engineering and/or the methods of developing a system are limited. The process of defining the requirements in building a network, designing the system, and building the network focuses on arranging the methods of building a network. Based upon this, we tried to develop a necessary index to evaluate the security of a network.

An evaluation and comparison of seven of the world's major building codes and standards is conducted in this study, with specific discussion of their estimations of the alongwind, acrosswind, and torsional response, where applicable, for a given building. The codes and standards highlighted by this study are those of the United States, Japan, Australia, the United Kingdom, Canada, China and Europe. In addition, the responses predicted by using the measured power spectra of the alongwind, acrosswind and torsional responses for several building shapes tested in a wind tunnel are presented and a comparison between the response predicted by wind tunnel data and that estimated by some of the standards is conducted. This study serves not only as a comparison of the response estimates by international codes and standards, but also introduces a new set of wind tunnel data for validation of wind tunnel-based empirical expressions.

Community building in Japan, called Machizukuri, has been in existence since the 1960s, and many successful cases are referred to by researchers and public service officials as benchmarks for creating livable cities and towns in Korea. The purpose of this study is to identify the building factors for a sustainable community and to suggest implications through the cases of machizukuri in Japan. Based on the literature review related to the research topic, on-site visit case study was used as the major research methodology. Four cases -Setagaya, Kawagoe, Motomachi, and Manazuru- were selected as the research subjects and interviews with the representatives of the community(resident) council and public officials were conducted during October 19-22, 2011. The project overview, purpose, and planning characteristics of each case were described for data analysis. The major findings are as follows. Although most of the machizukuri in Japan were administration-dependent at the beginning stage, the case projects in this study showed resident-independence (self-support) from the perspective of sustainability. The results showed that successful community building is an everlasting project that requires cooperation among personnels including residents, civic officials, and related council members.

Academic societies in the field of science and technology are major producers of domestic research information. These information are very important sources to researchers, students and so on. KORDIC built an integrated information system which facilitates the progress of building databases and promotes users easy access to databases. In order to build efficient society research information system, we investigated former cases and analyzed requirement of each society. We identified principal information sources and built an integrated information service system using internet homepage and information retrieval system(KRISTAL-II). In the future we will expand participating societies and focus on text-based information.
