Eco-friendly architecture, generally speaking, is considered as the activity of planting more and designing ponds, therefore many clients and constructors prefer to avoid building so due to initial construction costs. This paper aims to examine the cognition of environmental equipment systems and the applicability of echo-friendly building constructions. We examined the designer's demands of building equipment systems and eco-friendly environment and tried to deduce desirable suggestions for the system. We should solve the fundamentals of economical problems in the construction of eco-friendly buildings and we better think that government should make it a policy to advertise it and to reform the taxation system regarding environment friendly buildings.

The aim of this study is to improve quality system through mutual understanding for the opinion gap among interested parties such as owner, designer, constructor and supervisor in construction industry. The survey to the owners, designers, constructors, and supervisors who are in charge of quality of the 183 architectural projects being constructed has been performed for investigating the importance and actual level of quality and quality factors. Questionnaires are based on the quality factors shown in ISO 9001:2000 international quality management system requirements. There are distinct opinion gaps for quality among owner, designer, constructor, and supervisor who working for the same architectural projects.

In the process of designing a building, the process of expressing the designer's ideas through images is essential. However, it is expensive and time consuming for a designer to analyze every individual case image to generate a hypothetical design. This study aims to visualize the basic design draft sketch made by the designer as a real image using the Generative Adversarial Network (GAN) based on the continuously accumulated architectural case images. Through this, we proposed a method to build an automated visualization environment using artificial intelligence and to visualize the architectural idea conceived by the designer in the architectural planning stage faster and cheaper than in the past. This study was conducted using approximately 20,000 images. In our study, the GAN algorithm allowed us to represent primary materials and shades within 2 seconds, but lacked accuracy in material and shading representation. We plan to add image data in the future to address this in a follow-up study.

BIM based design methodology requires more information than traditional design methodology in order to insure efficiency throughout the project. BIM based design not only requires all building data in the form of 3D shapes, but also all other relevant data regarding building components. Information is typically grouped in a standard classification system such as by standardized material names. The development of a domestic BIM based standard classification system is yet to be created and deployed in the industry. Each designer is specifying their own building information classification systems which is causing inconsistency in the industry. Therefore BIM based designs, are causing confusion in the industry as each designer follow no guidelines for material standardization classification. The lack of information regarding this in the BIM template will continue to cause confusion about a projects building information data consistently. This study is that of preliminary research to develop a BIM template. First, overseas BIM templates were analyzed regarding BIM standards and documentation. Examination then followed regarding the element and characteristics needed for the development of a BIM template, a suggested hierarchy of elements required for a BIM template were then made. The result of this research is that it will be used to develop a "BIM template prototype", to support the generation of building information data regarding neighborhood facilities.

In Japan, it has been argued between architects and contractors that which process is desirable, the traditional process or the design-build process. It is called the contractor-designer issue. In 1968, Kajima Corporation chairman Morinosuke Kajima and the Japan Architects Association had a public controversy over it. On the other hand, in practice, architects and contractors have secured quality of buildings thorough a close communication in the design and construction process of building. What are the relationships between architects and contractors? What roles do architects and contractors have in practice? This study has two aims. First one is to analyze the contractor-designer issue based on roles and relationships between architects and contractors, and then to show conflicts between them. Second one is to consider issues which architects face in the relationships with contractors.

In the reinforced concrete structure, as the height of building structure increases, the accurate estimation of differential column shortening is important factor in the structural design. In this study, the analysis of column shortening is applied to 36-story building structure to be built in time. As a result, it may found that, as the difference of compressive stress become larger, differential shortening effect due to creep and shrinkage are more signicant factor to structural designer.

Purpose: The life span of a hospital building is short. This is because the building will have to be built up due to the fact that it can not cope with the new medical environment, it can not be replaced due to low floor height, lack of land. The purpose of the hospital building master plan is to find a way to fulfill its role in the long term. Methods: Comparison the proposals submitted by the master plan and the proposals submitted by the hospitals, the case of three hospitals that have established a master plan for the past three years. In addition, interviews with the designers who participated in the design competition and the administrator of hospital about the variables that occurred during the business process. Results: The result of this study can be summarized into four points. The first one is that master plan is changed by administrator of hospital so that Thy need to understand about the role of master plan. And next is to protect reduction of the project cost. Third, continuous participation of master plan researchers in following projects is good to communicate with administrator and designer. The last one is empathy of master plan by designer and users. Implications: It is necessary to reduce changing of master plan in design process for sustainable managing of hospital.

Generally, H.V.A.C load capacity in early planning phase can presume with maximum thermal load. Basic data can prove by air conditioning equipment system data analysis at existing building. There are poor and not reliable alternative presentation. In this paper, measured data after use H.V.A.C load calculation K-load program reply choosing standard building and variables simulation. And I founded peak load correlation graph and mode for several kinds of variable and contents of size. I wish that equipment designer is beaconed to produce optimum capacity at building as quantitative through this result.

Within residential high-rise market there are many value determining factors. Site condition, view, program, units and structure are important parameters that are directly related to the financial aspect of the project. However, most of the studies of high-rise building design focus on the facade and the shape strategies from an esthetic point of view without considering these factors. The objective of this study is to investigate new design approach that incorporates site, program and structural information at an early stage as a generator of building form and explore a wide range of strategies to negotiate these factors in the process of design/decision making. Not being based on designer's subjective preference or style, architects still can create interesting building design through integration and negotiation of various building information. Since this form is based on real data, not just play of form, we can expect that this form has great potential to be developed into real one at the later design phase.

To express the original texture of the concrete, exposed concrete finishing technique has been applied in many buildings. However, it is likely to cause quality problems after construction is completed. In addition, because of costs and time issues, reconstruction and maintenance works are difficult and ineffective. Therefore, step-by-step proactive quality management based on sufficient consensus among participants(client, designer, contractor) is very importatnt. This study analyzed factors causing low quality exposed concrete and quality contol points applied to 'A' headquarter construction project.
