Light environment in the school building is one of the most important elements of the plan in order to improve student's ability to learn and the healthy growth. Thus, the window plan of the school building is a great addition to improve environmental-friendly performance through the daylight control. Daylight is highly beneficial for improving the indoor environmental quality and reducing building energy consumption, daylighting applications are scarcely considered, especially during the school building design process, because of lack of previous studies on the light environment of student and complex simulation process. Therefore, daylighting process were performed using ECOTECT, which has various advantage such as easy user interface and simple simulation processes. ECOTECT simulation were performed using weather data. As a result, ECOTECT simulation are performed for daylight autonomy and useful daylight illuminance. Using this data, Window planing is to propose and effective method in the early stages of design.

Building hardware joints are welded in most cases, which have risks of fire and explosion. Besides, the secondary damage of the destruction of the welded parts can be caused by the horizontal displacement of the structure due to earthquake or wind load. This paper compared the horizontal displacement following abilities of welded building hardware and non-welded building hardware. To do this, We conducted actual formation shake table test, and checked on the horizontal displacement following ability of structure by comparing their responses to earthquake load. We made the 2m-high framework to examine the responses of the actually constructed building hardwares, and analyzed the displacement responses of the welded-typed, non-welded-typed, and cruciform bracket building hardwares. We conducted the test by increasing acceleration rate until displacement reached 40mm corresponding to allowable relative story displacement II. The result of the test showed that the building hardware using welding work made cracking and breakage on welded connections of welded building hardware, but non-welded building hardware with no use of welding work and cruciform bracket building hardware make no problem, and that non-welded building hardware is superior to that of the welded building hardware in the horizontal displacement following ability due to earthquake or wind load.

With the increase in the demand for sustainable and environmentally-friendly development, Green Building Certification System came into force in 2002, Evaluation parts of Green Building Certification System are divided into land use and transportation, energy, ecological environment, and indoor environment. Alloted point for the part of energy is larger than other part, thus we can say that this part is very important to increase the green building performance. This study aims to analyze the present condition of design and construction for the part of energy in the certificated green school building. Total 40 certificated school buildings were selected and average scoring rate of each item was evaluated. Key particular to be considered were suggested to improve the item of energy consumption.

House supplying rate of building facilities is over 100% in 2008. In modern society, many people are thus interested in maintenance phase of building facilities by environment improvement budget because 20 years or more of building facilities are increasing rapidly. Maintenance of building facilities is depending on various factors that impact on the environment improvement budget of building facilities. However, Various methods and factors are made up complex relationships. I will analyze that environment improvement budget associated with floor, gross area, local, school type, service life and other elements.

Building-Integrated Photovoltaics (BIPV) is a photovoltaic (PV) technology which can be incorporated into the roofs walls of both commercial and domestic buildings to provide a source of electricity. BIPV systems can operate as a multi-functional building components, which generates electricity and serves as part of building envelope. It can be regarded as a new architectural elements, adding to the building's aesthetics. Applying PV modules on roof has an advantage over wall applications as they seem to receive more solar radiation on PV modules. There are various types of PV applications on building roofs: attached, on-top and integrated. This paper describes the classification and characteristics of PV applications on roofs.

In the construction industry, there has been a surge in the implementation of high-tech equipment in recent years. Various technologies are being considered as potential solutions for future construction projects. Building information modeling (BIM), which utilizes advanced equipment, is a promising solution among these technologies. The need for safety inspection has also increased with the aging structures. Nevertheless, traditional safety inspection technology falls short of meeting this demand as it heavily relies on the subjective opinions of workers. This inadequacy highlights the need for advancements in existing maintenance technology. Research on building safety inspection using 3D laser scanners has notably increased. Laser scanners that use light detection and ranging (LiDAR) can quickly and accurately acquire producing information, which can be realized through reverse engineering by modeling point cloud data. This study introduces an innovative evaluation system for building safety using a 3D laser scanner. The system was used to assess the safety of an existing three-story building by implementing a reverse engineering technique. The 3D digital data are obtained from the scanner to detect defects and deflections in and outside the building and to create an as-built BIM. Subsequently, the as-built structural model of the building was generated using the reverse engineering approach and used for structural analysis. The acquired information, including deformations and dimensions, is compared with the expected values to evaluate the effectiveness of the proposed technique.

Problems like poor security, transfer delay or packet loss occur while building network systems that are applied with TCP/TP integrate with data network systems. To solve this problem, this paper proposes the Separated Ethernet, which can give priority to the system, and by using the OPNET Modeler simulator, we will verify its performances.

The aim of this study is to develop a strategy for building healthy schools. For this, the concept of a healthy school was defined and the need for healthy schools was identified and reviewed. This included comparative studies of foreign countries as well. This study found that the elements of a healthy school were physical, psychological, environmental, nutritional, educational, serviceable, and practical. The strategy of building this model was to connect students and teachers, school and administration, and parents and community within one circle on the basis of these elements.

The paper is to evaluate existing school building system with respect to students' comforts in the class room in Korea. This paper compared three styles of different school building system builted during last 20 years. Using statistical analysis, at first, the paper found that box-style structure is efficient for sustaining heat in the class room because it is compactly constructed. Secondly, air conditioning in the class room is important factor affected students' comforts in the summer time and for the smog occurring in the heating class room. Thirdly, we should compactly construct school building because the compactiveness of building components is important factor for student comforts. Fouthly, heating system in the class room should be changed. The system using gas or electricity insteded of coals should be introduced in the class room for the smog of the stove in winter time and for freshness in summer time.
