As residents and building owners demand maintenance that is required to achieve sustainable building performance, efficient building management methods are required. Even though the demand for maintenance systems is increasing, current maintenance work for high-rise buildings mostly uses conventional ropes and gondolas that pose a high risk of accidents and exhibit poor performance and efficiency. Thus, there is an urgent need to develop an automation robot system that can reduce accidents and improve the maintenance efficiency of the conventional high-rise building façade maintenance system. As a preceding work for the development of an automation robot system, this study classified and analyzed the work processes of actual construction sites and proposed basic techniques for the work mechanisms of the robot system by investigating the motions of cleaning workers.

Due to the recent depletion of natural resources and global warming, a passive house type building exterior system has been developed and applied. For this purpose, we developed a building exterior thermal resistance performance evaluation system and verify the feasibility of this system for evaluation of passive house building system.

This study aims for improvement and rebuilding of the 'Green Building Certification Criteria Information System;GBCCIS'. To achieve this, improved information system has developed self-assessment program available on the web and to provide data about the target of Green Building Certification based on the 2010 revised criteria. The target building of Green Building Certification is Apartment, Office, Mixed-Use Building, School, property for sale, accommodation, and other facilities. Also, the information system about the Green building related technologies and techniques to take advantage of offer a variety of information was built. Green Building Certification Criteria web-site Established in this study has information and each menu and contents are linked to organic and high-utilization. Each menu is organized according to the used frequency and the group. Also this web-site is composed of information guide field, core service field, and other field. These improvement of Green Building Certification Criteria Information System can be a positive incentive measures for the activation of Green Building Certification Criteria easily by taking advantage of relevant information by users. And these will be possible to planning development of Green building technologies by introducing the latest Green building construction techniques applicable building. Also, to assess in advance by using self-assessment program in the design phase of building will lead to Green building design and provide the convenience of the application process and through database construction and share information of building assessment resources certified Green Building Certification Criteria will lead to the containment and fair assessment between cation authorities.

Elevator stops emergently when power failures happen during operation. In that case, the passenger should wait with frightened in the car untill they are rescued by repair man or power resumes. This paper describes an automatic landing device for power-failure(ALP) that consists of UPS and battery charge control system. The excellence of the ALP operation is verified by experiments in elevator test tower.

This study aims to analysis domestic energy consumption in Korea and reduction greenhouse gas by building mechanical system. At this point be tormented the energy depletion and climate change of earth are big problems on the eatrh. In this paper we will find out best methods to reduction greenhouse gas and energy consumption by practical building mechanical system. Enlargement of greenhome and building adopt, greenhouse gas exhaust reduction in building, publication of energy consumption rate, publish building energy management manual, etc.

This study aims to choose installation location of wind power system and analyze influence factors of wind power system by shape of super high-raise building by using CFD simulation. As a result of this study, wind power system is more applicable to streamlined building than normal building. Round openings are seemed to be the most efficient shape for building integrated wind power system in types applying venturi effect. Safety and vibration should be considered in the case of application of wind power system between the buildings.

The purpose of Green Building Certification System is to promote the environment-friendly building construction as the life-cycle environmental performance of a certain building is assessed and certified nationally(domestically). By the way, a building can get the green building certificate just with the minimum standard in prerequisite assessment criteria and with the designated scores in totals. GBCS consists of 9 assessment issues and it has 4 grades. Nevertheless the 1st. grade green building has uneven scores in each issue. In other words, it has even 0 point in a special issue. Due to the above problem, the discrimination and reliability in the GBCS grading and scoring has to be secured. This study aims at a new grading and scoring system equipped with the discrimination and reliability through analysing the scores of prerequisite assessment criteria and the scores by issues in the actually certified green office buildings.

The purpose of this study is to identify the characteristics of the use of the western building system with the change of the architectural design in the Japanese colonial period focused on the facility built by Joseon Government-General in 1910s. Through the 131 cases of governmental building, the tendency of the use of western building system. After 1910, Japanese Imperialism adopted the western wooden building system which main structure was made with combination of small pieces of timber for building the modern governmental facility because of the political and financial intention. So, all facilities were designed similarly by the structural module and the facade was finished by the feather boarding in the same with the 'sitamitakei-giyohu' in Japan. the functional requirements of each facility was not revealed. Such an western wooden building system was used until 1920s with the change of the facade by the mortar coating. But, in 1920s-1930s, the building system have begun to change. The use of the brick system caused some changes although the planing concept was still lasted. On the other hand, the use of the reinforced concrete led to more changes on the overall scheme.

In this study, the evaluation of environmental performance of the building energy system of domestic commercial sector was carried out. Based on the theory of linear programming model, we established an evaluation model satisfying object functions and constraint conditions. Employing the model, the evaluation of building energy system was performed under the consideration of cost and environmental constraint conditions. As an evaluation tool, MARKAL (MARKet Allocation) known as a market distribution model was employed. We analyzed scenarios of Case I (Base Scenarios) through Case IX established by the combination of the components of building energy system such as glazing, building skin, core, and heat source system. According to the results of the evaluation, highest contribution on the useful energy demand was obtained from the building energy system combined with solar heat source system, when the total amounts of $CO_2$ exhaust as an environmental constraint condition is assumed to be the level of 1995.

System Integration is significant role in building, because it is that the more building system is integrated, the more they can save management costs and energy costs. Nowadays system protocols in building use BACnet, LonWorks, etc. to integrate effectively, but their interoperability is not perfect. Therefore, we propose system integration using Ethernet and TCP/IP for perfect harmony. When data network protocol, Ethernet and TCP/IP is used for control network, there are several problems. But there have been solved by many researches. therefore it is possible that building system integrate to use Ethernet and TCP/IP. Finally, we show that Ethernet and TCP/IP can be used for building automation system integration.
