Value Engineering(VE) is an organized effort to create the most value through a functional analysis and creation of alternatives. Depending on the VE job plan, a VE Workshop must be performed in a certain place within a certain period of time. A VE Workshop, which is an organized activity that aims to create the best value through functional analysis and creation of alternatives, should be held in a certain place and at a scheduled time according to the VE job plan. In the Pre-Study, VE Study and Post-Study phases of VE, functional assessments, performance evaluations and idea evaluations are driven by variable management techniques and analysis methods, respectively. Generally, VE is executed for about 3 to 5 days in a particular place to create value. However, there are many problems associated with limiting all VE processes to a specific place and schedule. Moreover, in Korea, VE teams are required to finish all VE processes in a limited time because of the short duration of VE workshops, the necessity of which has been overlooked. Therefore, an efficient VE support system is required to resolve the problem of time and space limitations. In this study, a VE support system based on the Mobile environment was developed to support the VE Workshop process. This VE support system enables participants to review design documents, drawing sheets and all VE-related documents using mobile devices. After the Workshop, participants can conveniently rearrange the result(evaluation of function and ideas) at the workshop. Not only can the members of VE team can review the design documents, drawing sheet and all VE-related documents in the step before the workshop, but also the result(evaluation of function and ideas) of the workshop can be easily rearranged in the phase after the workshop under the developed supporting system using mobile devices.

Construction and urban development projects that drove urbanization were perceived as a main culprit that disturbs environment and ecosystems, including urban heat island, air pollution and a decrease in species diversity in urban area, as they do not consider natural environment and adopt consistent development behaviors and rapidly degrade the ecology of development sites. In order to build a sustainable green wall system, design process is configured as follows based on basic technology development direction, climate environment elements, climate design technology elements suggested earlier. Each part of required technology element is codified systematically and a sound Korean-style green wall system design direction will be suggested.

Recently, BIM is used at several areas actively because of introduction of BIM in the construction industry. In particular, the recent many studies on activation of BIM information sharing is underway and it is the future direction of BIM. Moreover, it should be clearly realized. In the BIM levels of domestic construction phase, Interference Review, calculating volume estimates in part based on the active research is underway. However, still interested in reviewing building codes have relatively little interest. As BIM enabled, The methods of reviewing building codes should be transformed into a automated system by using information of BIM. In overseas, they are already using diverse softwares for reviewing modeling. Thus, For an automatic review of building regulations research is needed. this study is research on the development Domestic building codes as an automatic review process by using BIM. In order to Automatic review of the current building regulations by using BIM, this study analyzes the characteristics of each piece of information.

About 30% of the total annual energy consumption on the earth is used in the architectural activities, including construction, maintenance management, and demonstration of a building. Also, 40% of the natural resource consumption, 50% of $CO_2$ emissions, and 20%~50% of industrial waste emissions are produced from a building. Unfortunately, the percentage of its energy consumption is staidly increasing year by year, about 8% every year, and it recently causes a sustainable architectural concept to come to the fore globally. Indeed, the importance of the sustainable architecture is increasingly becoming a worldwide trend. BIM(Building Information Modeling) is considered a new paradigm and a powerful method in building design, construction and maintenance. BIM has characteristics similar to a building's systems. All of the components in a model have a parametric relationship to each other. Understanding and capitalizing on these interrelationships typically takes numerous iterations that span multiple projects. Optimizing the integrated strategies and technologies for a high-performance, sustainable design requires a continual look at understanding how they work together to deliver the best potential. Throughout all of these concepts, we are going to be using a variety of tools that revolve around a BIM model. Some of the tools will require a heavier use of BIM than others, but all of them will utilize the model geometry you've created as part of your design. This study presents importance and validity of energy performance analyzation in the pre-design phase for the sustainable architecture with the support of Building Information Modeling (BIM) technology.

본 논문에서는 KBC(Korean Building Code)와 IBC(International Building Code)의 풍하중 기준의 비교 분석을 통하여, BIM 프로세스 기반의 구조해석 및 설계 프로그램에서 풍하중 산정 시 국내 건축구조설계기준(KBC)을 적용하기 위한 방안을 제시하는 것을 목적으로 한다. 현재 BIM 기반 구조해석 및 설계 프로그램 중에는 한국구조설계기준(KBC)에 부합하는 풍하중 산정이 가능한 프로그램이 존재하지 않는다. 구조설계 기준에서 특히 풍하중 산정 방법은 기준 및 지역에 따른 산정 방법에 차이가 있기 때문에, 구조설계의 안전성을 높이고 한국 실정에 맞는 건축물의 설계를 위해서 KBC 기준의 적용이 필요하다. 본 연구에서는 IBC와 KBC 내의 풍하중 산정 방법의 차이점을 비교 분석하고, 실제 사례연구를 통하여 풍하중 산정의 차이를 확인한다. KBC 기준 풍하중 산정 결과를 구조해석 및 설계 프로그램에 적용하기 위한 방법으로써 외부 프로그램을 활용하며 외부 프로그램에서 산정한 풍하중을 다시 구조해석 및 설계 프로그램 상에 입력하여 구조해석을 수행함으로써 KBC 기준 풍하중의 적용을 통한 한국형 BIM 구조해석 및 설계의 방안을 제시한다.

This study is a practical research for setting a process of making references of design decision and guidlines of limitation in the movement from the design development to the construction design by StrAuto. StrAuto, as a parametric modeling and optimization tool for building structure, enables a quantity of design cases to be analyzed automatically by changing parameters of sturctural properties. So the designer using StrAuto can check a lot of analysis data crossing thousands of cases, see which case is out of acceptable range, and make a decision for design and optimization. In this thesis, the application of StrAuto optimization process to the residence tower UIC project shows the practical applicability in the construction design and value engineering. StrAuto optimized ideally volume of core walls by 31.3% and lead the final revised model applied to the construction design to reduce volume by 18.1%. The significance of this research is the implementation of process that the designer can quickly review a number of cases and get a direction for construction design and optimization after design development.
