Smart windows are capable of varying their visible light transmittance (VLT) in response to changing environmental conditions. The VLT variability of architectural windows is highly valuable because it enables indoor lighting and energy environments to align with external changes. However, challenges such as high installation costs and assurance of glass visibility have prompted the exploration of alternative solutions, including models incorporating partially applied smart windows., Prior research focused on useful daylight illuminance (UDI) analysis for south-facing office buildings, pointing out suitable areas for smart-window implementation to enhance lighting control. In this study, we broadened this scope by determining optimal smart-window application zones under changing building orientation. Furthermore, we studied the correlation between building orientation and smart-window deployment areas.

Breakdown structure (BS) is a tool used to allocate information packages for various management functions and drive computerized information systems. Although several BS exists, work breakdown structures (WBS) and cost breakdown structures (CBS) are the most widely studied and used in previous literature. Nevertheless, heterogeneity of BS and respective management capabilities in current practices are not adequately addressed. In this context, this paper compared the management capabilities of various BS in both building and plant industries through systematic literature. Management requirements and applications scope, in terms of life cycle and stakeholder, were analyzed, respectively. Finally, finding and lesson-learned are outlined.

In the field of domestic construction, 3D modeling mainly targets outdoor construction sites, and acquires outdoor spatial information by operating UAVs and UGVs equipped with cameras. 3D modeling of construction sites tends to expand its scope to indoors along with the increasing demand for site monitoring and management through indoor spatial information. In the case of indoors, it is impossible to shoot with a drone after the framework and outer walls of the building are completed, so it is necessary to collect indoor spatial information and 3D modeling using a 360 camera. The purpose of this study is limited to basic research to establish a process that can obtain simple and high-quality indoor 3D modeling results using indoor data collected from 360 cameras.

Aging buildings over 15 years reaches about 74% of 177 thousand buildings in Domestic public buildings. Due to the aging building, the energy loss is a serious problem. In order to reduce the energy usage through improving the energy efficiency on the existing buildings, the government & the local autonomous entity conduct the energy efficiency projects through the remodeling, repairing & equipment replacement on the existing buildings. The green remodeling is applied to the existing public buildings in recently revised the act on the creation and support of green building. However, the standard is not obvious that the work scope of green remodeling, financing and project delivery method. This paper propose is to suggest project delivery system for vitalizing the green remodeling. Green remodeling is defined on basis of the occurring work under project life cycle based on the existing building process and the financing method for owners and companies and the project delivery system according to work scope of green remodeling are proposed in this paper

The purpose of this thesis lies on building the foundation for the further activation of trade among the Northeast Asian countries such as South Korea, Japan, China, Russia, and North Korea through an analytical comparison of their arbitration systems. Further activation of trade cannot be reached without previously building safety measures on the negotiation of exports, the control on defective imported merchandise, the returns on investments, and the stable management of businesses. Throughout this thesis an analytical comparison of these five countries' most important areas on arbitration will be carried out. These areas are the arbitration laws and organizations; the structures of the laws; scope of arbitration; form of arbitration agreement, appointment of arbitratiors, place of arbitration, hearing, court assistance in taking evidence, governing law, decision making by panel of arbitrators, form and contents of awards, effective of award, recourse against award, recognition and enforcement of awards. etc. It was found in each of the areas cases to be identical, similar or verydifferent; also, cases unable to arbitrate. This phenomenon was found to occur due to the differences in political and economic systems and perception of arbitration among these countries. Additionally, this thesis points out what should each country do for its integration. It is also suggested the organization of a common arbitration research body to continue the efforts for raising the awareness, building trust, and mutual recognition among the countries to ultimately create a common arbitration system. Lastly, it is a personal will that this thesis will serve as the starting point for in depth researches in each of the presented areas.

In order to overcome the limitations of th 2D method regardless of the client's request, the application of BIM was reviewed to create hight-quality products using 3D models and various BIM information for offshore wind jacket-type structures. First, we defined the input value through analysis of the target structure and wrote an algorithm(script library) and library to complete the BIM model. Design review using geometry information based on th BIM model, usage for visualization drawings and quantity calculation were reviewed. For the purpose of initial review, only libraries with a limited number of subjects limitations on the scope of research were used. However, in the futrue, various libraries will be developed and research will be conducted to expand the scope of subjects.

Geospatial research on emergency response in multi-level micro-spatial environments (e.g., multi-story buildings) that aims at understanding and analyzing human movements at the micro level has increased considerably since 9/11. Past research has shown that reducing the time rescuers needed to reach a disaster site within a building (e.g., a particular room) can have a significant impact on evacuation and rescue outcomes in this kind of disaster situations. With the purpose developing emergency response systems that are capable of using complex real-time geospatial information to generate fast-changing scenarios, this study develops a Spatiotemporal Optimal Route Algorithm (SORA) for guiding rescuers to move quickly from various entrances of a building to the disaster site (room) within the building. It identifies the optimal route and building evacuation bottlenecks within the network in real-time emergency situations. It is integrated with a Ubiquitous Sensor Network (USN) based tracking system in order to monitor dynamic geospatial entities, including the dynamic capacities and flow rates of hallways per time period. Because of the limited scope of this study, the simulated data were used to implement the SORA and evaluate its effectiveness for performing 3D topological analysis. The study shows that capabilities to take into account detailed dynamic geospatial data about emergency situations, including changes in evacuation status over time, are essential for emergency response systems.

The environment is the important resource to use as well as to conserve for the development. Since 1990s, it has accentuated the importance of the environment and tried to conserve the environment in many areas. Among many area, the building industry has played a role to destruct the environment for providing the living decent space and brought the environmental affect. Therefore, the building industry should endeavor to mitigate the environmental affect. In building life cycle, it consumes the energy and natural resources. But it is difficult to evaluate the environmental affect during the whole building life. It is impossible to calculate the environmental affect without the much time and effort. Therefore. it requires the easy and handing program to calculate the affect to environment in each building life cycle. Until now, many program for assessing the affect to the environment have been developed and limitedly used because of the assessment scope and contents. In this paper, it aimed at developing the assessment program of LCA, focused on the energy consumption and carbon-dioxide emission compared with the domestic and foreign concerned programs. The developed program is divided into 3 areas; construction, maintenance, demolition.
