The University students learn their major or a general education in lecture rooms. In these days, lecturer use frequently various multimedia in lecture room. Appropriate control lighting environment in lecture room should be essential and related in efficient studying. Daylighting on front-side of lecture room will cause glare and students are hard to read contents on white-board at their seat. Therefore, in order to preventing glare we simulated daylighting of lecture room with using computer software in this study. Results from simulation and analysis as follows: The first, if students' left-side is east-oriented in lecture room, best daylighting condition about glare in lecture room. The second, architectural designers can use simulation data of daylighting or simulate data in designing university buildings with lecture rooms. Finally, if reducing size of windows (narrow and deep daylight: more closing vertically, from up to down daylighting: more closing horizontally) we will be able to reduce energy from lecture room.

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.

In this article, we look at the application of BIM (Building Information Modeling) in sustainable infrastructures. In response to global warming, energy shortages, and environmental degradation, people are trying to build eco-friendly, low-carbon cities and promote eco-friendly homes. A "green" building is the entire life cycle of a building that includes maximizing the conservation of resources (energy, water, land, and materials), protecting the environment, reducing pollution, providing people with healthy, comfortable, and efficient use of space, and establishing harmony between nature and architecture. In the field of ecological and sustainable buildings, BIM modeling can be integrated into buildings with analog energy, air flow analysis, and solar building ecosystems. Using BIM technologies, you can reduce the amount of waste and improve the quality of construction. These technologies create "visualization" of digital building models through multidimensional digital design solutions that provide" modeling and analysis "of Scientific Collaboration Platforms for designers, architects, utility engineers, developers, and even end users. Moreover, BIM helps them use three-dimensional digital models in project design and construction and operational management.

New technologies using a CNC machine are being developed to reduce the production cost of free-form buildings. For production of free-form members using such technologies, vast free-form buildings should be first split into multiple panels that are productible. Taking into consideration of the curved surface of free-form members, the segmented free-form panels may vary in shape and size, which may cause a lot of errors. In addition, it is time-consuming for the work. However, the current panelizing work is completed with the trials and errors of engineers and architectural designers even in large-scale projects, which results in increased construction duration and cost. Thus, it is necessary to develop a technology for panelizing free-form panels so as to maximize the economic feasibility of production technologies for free-form concrete members. The study intends to develeop automatic panelizing algorithms of free-form buildings considering the curved surface and size of free-form panels and the production conditions. The developed algorithms will be useful in applying the production technologies of free-form buildings using CNC machine and reducing the cost.

The energy demand in the world is expected to exceed 740 million TJ by 2040 and our dependence on fossil fuels needs to be switched to sustainable and renewable energy sources like solar energy. Building Integrated Photovoltaic (BIPV) is one of the best approaches to extracting solar energy. There are more than 200 BIPV products in the market currently but when it comes to integrating these products into the technical aspects such as buildings' structural integrity, thermal, daylight retainment and aesthetic prospects to be considered. The share of BIPV integration potential of different building types in the world of residential, agricultural, industrial, commercial and other buildings account for 66%, 4.8%, 8.1%, 19.9%, and 1.2% accordingly. Many solar technologies developed to achieve architectural requirements, but the main problem is the trade-off between efficiency and aesthetic appeal, which is less than 10% in coloured and transparent solar modules. This paper discusses the different applications of solar photovoltaics (PV) in building architecture, technical requirements, and different module technologies. The article provides a comprehensive guide for researchers and designers working on the development of BIPV integrations.

In the study, the effects of damping devices on damping ratio increase and wind-load reduction were investigated based on the computational platform, which is one of the parametric modeling methods. The computational platform helps the designers or engineers to evaluate the efficacy of the numerous alternative structural systems for irregular Super-Tall building, which is crucial in determining the capacity and the number of the supplemental damping devices for adding the required damping ratios to the building. The inherent damping ratio was estimated based on the related domestic and foreign researches conducted by using real wind-load records. Two types of damping devices were considered: One is inter-story installation type passive control devices and the other is mass type active control devices. The supplemental damping ratio due to the damping devices was calculated by means of equivalent static analysis using an equation suggested by FEMA. The optimal design of the damping devices was conducted by using the computational platform. The structural element quantity reduction effect resulting from the installation of the damping devices could be simply assessed by proposing a wind-load reduction factor, and the effectiveness of the proposed method was verified by a numerical example of a 455m high-rise building. The comparison between roof displacement and the story shear forces by the nonlinear time history analysis and the proposed method indicated that the proposed method could simply but approximately estimate the effects of the supplemental damping devices on the roof displacement and the member force reduction.

The purpose of this study was to analyze the monumental expression of Korean War Memorials(KWM) in Korea(KWMK). Through site survey and internet searching, the researcher selected 17 KWMK and analyzed four analysis categories: contents, spatial form, landscape elements, sculptures and architectural elements. The results are as follows: 1. The analysis revealed that main contents of KWMK were to cherish victims of the Korean War, honor military merit, and explain Korean War. 2. Most KWMK built battlefield had the form of symmetry and spatial axis arranged monuments and sculptures for solemnity and heroism. Though the sites were terraced by traditional spatial order, spatial sequence wasn't seen except Yang-gu KWMK and Chumomyeongbi in United Nations Memorial Cemetery in Korea. 3. Stone monument-like towers, tablets, podium, monoliths, cenotaphs, and exhibit halls to explain Korean War and combat history were used as main elements of KWMK and also, war weapons were often displayed the flags of countries taking part in Korean War were raised with Taegeukgi and the United Nations flag. 4. Most sculptures were used as important media to represent the Korean War and assumed realistically the form of heroic combat. But a few architectural memorial built in recent were designed in contemporary style to have spatial sequence and represent Korean War symbolically and narratively. 5. In memorial culture, KWMK were strongly influenced by ideology and patriotism, impacted by conventional value, and designed by some sculptors and designers in a certain circle. Further study will be required to analyze the characteristics of KWMK in the point of design style and diachronic.

Recently, as smart construction has become more active, construction companys are evaluating their smart construction capabilities in order to transform into smart construction companies. However, the revitalization of smart construction doesn't only apply to construction companies, the level of utilization of all participants, including owners, designers, construction project managers, and construction company, must be improved. Therefore, this study aims to present a model that evaluate the building information modeling (BIM) utilization level for measuring the BIM utilization level of construction management companies in executing construction project management. In this study, an AHP questionnaire survey targeting BIM practitioners to calculate the weight of each BIM utilization item and score it to construct evaluation model and evaluate it by applying it to construction management companies are conducted. As a result of the evaluation using model, there were differences between companies in the number of BIM users, and in the qualitative evaluation, it is mainly used for interference review, constructability review, and design change management. Therefore, in order to revitalize BIM, it is believed that it is necessary to strengthen BIM utilization ability through separate training for construction manager (CMr) and to present clear utilization standards and scope of work for BIM utilization in performing construction management tasks. Consequently, evaluating more construction management companies using the model presented in this study will result in the transition of CM companies to smart construction and revitalization of BIM adoption.

A museum architecture has been developed as important representation of a specific period in architectural history. Modern concept of museum architecture has started by Karl Fredrich van Schinkel(1781-1841) through das Altes Museum(1823-1830) back in early 20th century and it continues to be the model for museum architecture for over 30 years. By middle of the 20th century, the movement of redefining new model for the new era on the subject of museum architecture was developed. This development was lead by the three masters of the modern architecture at the time. F.L. Wright, Corbusier, Mies and they were responsible and very active in creating new concepts. Their works in museum design became the prototype and they tried hard to make sure their new concepts to be the stepping stone for further development. This study is to compare the three different museums designed by those masters of the modern architecture, particularly on the issue of the exhibition spaces. The purpose of the study will be focused on the point of interior architecture such as the matters of layout and design characteristics of the exhibition spaces. And it will reveal the impact made by those masters on the advanced development of the current generations of museum designers as well as to describe the prototype of exhibition space. The analyzation was done on FLW's Guggenheim Museum in New York, Corbusier's the National Museum of Western Art in Tokyo, and Mies' Die Neue National Galerie in Berliv. Comparable materials were collected through site visits and reference documents from various publications. It will be ideal if this study can be used for further development in new museum design in this country.
