An architectural pre-design, which is conducted prior to the architecture design, supports fundamental configuration during the entire AEC project by predicting the cost, demand, etc., of the building, and is therefore gaining importance. In particular, the massing calculation of the pre-design phase should be prioritized, as it is fundamental to architectural outline. However, most architects depend on only their experience and intuition while conceptualizing an integrated framework of design conditions, including the building code and requirements for the massing calculation of the object. Therefore, many difficulties arise in terms of performing appropriate tasks. Thus, the purpose of this study is to implement a knowledge-based BIM for explicitly representing the design knowledge, which is the basis of decision making for an architect while performing the massing calculation. In particular, the 3D knowledge relevant to a project can be provided and accumulated in the massing calculation by the BIM system; this facilitates an integral understanding. Consequently, the approximate result of massing calculation in 3D BIM environment, through both the knowledge-based BIM template and plug-in, can be swiftly provided to the architect. In addition, the architect can invent various alternatives, estimate resulting costs, and reuse the accumulated knowledge in future BIM design processes.

To apply an analysis method of life cycle cost when assessing economics of equipment system, we should basically set up preconditions such as useful life, price escalation rate, interest rate, etc. as well as consider a calculation algorism of source energy and heat source system, which is a complex process for life cycle costing. For this reason, equipment designers tend to plan heat source systems, without a thorough investigation on economics of alternative systems at the pre-design phase. In this process, architectural designers should adopt a proper heat source system, which is one of the most important factors for planning an appropriate architectural design, through a discussion with equipment designers in a short time. In order to offer an evaluation method for equipment designers to analyze economics of an alternative heat source system easily at the pre-design phase, this research would define the simplified economics, evaluation method through analysis of existing papers for economics evaluation, and examine validity through comparison of simplified method values ($LCC_{EC}$) and life cycle costing values ($LCC_{15}$) for six alternative heat source systems.

합리성과 효율성을 끊임없이 요구받고 있는 현대사회의 시대적 흐름은 사회 전체의 패러다임이 되었다. 이 패러다임은 건축설계와 건설업계에도 큰 영향을 미치고 있다. 디지털 도구의 발전과 인터넷을 통한 정보기술(Information Technology)로 대변되는 현대 기술은 건축설계와 건설업계에서 파라메트릭 디자인(Parametric Design)과 BIM(Building information Modeling)이라는 두 개의 큰 흐름을 생성하고 발전하고 있다. 비록 각기 다른 이유로 탄생했으나 효율성과 합리성이라는 공통의 목적으로 서로의 경계를 넘나들면서 건축설계와 건설업계에 큰 영향력을 보이고 있다. 이러한 맥락에서 본 연구는 BIM 설계에 적용을 초기 기획설계단계에서의 파라메트릭 디자인이 어떻게 이루어져야 하는지에 대한 내용을 예시를 통해 구현해 보고자 했다. 해체주의(Deconstructivism) 건축가 "프랭크 게리"(Frank O. Ghery)의 작품인 월트디즈니 홀(Walt Diseny Consert Hall) 설계의 프로세스에 대한 고찰과 체코프라하의 네덜란덴 빌딩(National Nederlanden Building)의 형태를 파라메트릭 설계 툴(Tool)을 사용하여 기획설계단계에서의 형태를 구현하고자 했다. 향후 이 연구는 기획설계단계에서의 파라메트릭 디자인의 범위를 넘어서 궁극적인 BIM의 적용 즉 계획 및 실시설계 그리고 시공에 이르는 건설산업 전반에 적용 가능한 기초 자료로서의 목적에 사용되고자 한다. 향후 파라메트릭 디자인 알고리즘을 활용한 계획 및 실시설계단계에서의 BIM의 적용을 진행하고자 한다.

With recent attempts to improve quality and productivity, the prefabrication manufacturing system has been occupying an increasing share of the construction area. To minimize site work, material is more frequently being produced and partially assembled at a plant, and then installed at a site. For this reason, the production process is being divided and the materials are being delivered to the site after passing through multiple plants. With these changes in the production process, the materials delivery plan is becoming an important management point. In particular, as road transportation using trucks has a 71 percent share of the domestic transportation market, selecting the proper transportation path is important when delivering materials and equipment to a site. But the management system at the project design phase to calculate the delivery cost by considering the production process of the pre-fab material and the $CO_2$ emission at the material delivery phase is currently lacking. This study suggests a process design model for assembly production of the pre-fab material and transportation logistics based on carbon emission. The suggested model can be helpful to optimize the location of the intermediate plant. It is expected to be utilized as a basic model at the project plan and design phase when subcontractors make decisions on items such as materials procurement, selecting the production method, and choosing the location of the assembly plant.

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.

This study analyzes critical factors that affect issues of resolving time in BIM-based coordination using a case study. According to recent buildings that are meant to be more complex, BIM-based design coordination is regarded as an essential stage of the project delivery process. In the design coordination phase, a relocation of architectural, structural, mechanical, and electrical elements is conducted to avoid interference. In addition, the procedure of the development of each element in detail for the actual construction is carried out. Delays in coordination can affect delays in the entire delivery schedule of the project, and therefore many researches have focused on efficient coordination methods and how to shorten the period. In this study, we conducted a detailed analysis of the issue-resolving process using a case study, and found out that the participation of decision-makers for issue-resolving and the physical combination of trades affect delays in coordination time. In particular, we proposed the concept of organizational relation, indicating the level of decision-makers for issue-resolving, and the concept of physical relation, indicating the physical complexity of the issue, and we analyzed the effects of coordination delays.

This is part of a study on the origin of modernist forms and settings. Forms in Modern Architecture are totally new as though they seemed to be originated from some remote culture. Archaeological studies and Laugier's primitivist attitude to the classical architecture provided a way leading, in the end, to pure structures and abstract forms. An application of the classical elements was combined with the ultimate image of nobility, simplicity and rationality. What the seventeenth and eighteenth century theorists realized in the ruines of the classical structures were not the ones with their original organic vitality but the deteriorated, naked and abstracted ones. The essence of the classical structures has been the one of the main references of the modern white architecture. Ration and Nature were the quintessential terms in the design process of the Enlightenment architects of the late eighteenth and nineteenth centuries as they were in the twentieth century architecture. Pure geometric and symbolic forms were new inventions for the new revolutionary age after the development of architectural Styles, successive until Baroque and Roccoco, ceased to go on to the next phase. Many of their buildings appeared so modem in character, for they were omitted all but the essential structure and decoration. Other sides of rationality in the pre-modern age were evolved in terms of the paradigmatic research and the logic in structure. Durand developed a systematic typological approach to the forms. Geometry was the basis of his designs and his illustrations resembled endless simple geometrical problems. One of the other rational approaches was mainly developed by Viollet-le-Duc. To him, Gothic architecture was the model in which each members functioned actively and exerted counterpressure and the Middle Ages invented new fantastic forms. The several ways of rational approaches in architecture were led to the 'tabula rasa' planning in modern architecture. Nature was remained untouched and not deformed as Ledoux's houses in the $H{\hat{o}}tel$ de $Th{\acute{e}}lusson$ were setted on informal gardens. It is part of the modem image that Nature flows or interpenetrates through the white prisms of the strictest classical purity and machines.
