As the existing school building power consumption is expressed by total power consumption, in the view of energy saving is disadvantage. The the power consumption of school building is divided as cooling, heating, lighting and others. The cooling power consumption, heating power consumption, lighting power consumption can be calculated using real total power consumption that gained from Korea Electric Power Corporation(KEPCO). The power consumption for cooling and heating can be calculated using heat transmittance, wall area and floor area, and for lighting is calculated by artificial lighting calculation. but this calculation methods is difficult for laymen. This study was carried out in order to establish the regression equation for cooling power consumption, heating power consumption, lighting power consumption and other power consumption in school building. In order to verify the validity of the regression equation, it is compared regression equation results and calculation results based on real power consumption. As the results, difference between regression result and calculation results for cooling and heating power consumption showed 0.6% and 3.6%.

The purpose of this study is to present improvement for classification system of current neighborhood living facility to correspond rapid social change and various industries after understanding its status and problem. In current Building Standard Law, various kinds of buildings are classified for their structure, purpose of use, and building types. The Neighborhood Living Facility is divided into First Neighborhood Living Facility and Second Neighborhood Living Facility with applying area standards, according to facilities of convenience degree for neighborhood inhabitants. This classification, however, has problem in an arbitrary decision and applying of buildings without any definition or standards to adopt. And, there are some mixed neighborhood public functional facilities and amusement business affecting public morals among the Neighborhood Living Facility, so hazard environmental problems are also existed. According to the improved program, the study presents a prompt adoption of new facilities according to various industry increase, with minimum public discontent over adopted area standards. This study suggests making a clear scope through reclassification of Neighborhood Living Facility within the scope of the law on current Neighborhood Living Facility and an improvement plan of introducing necessary definitions on purpose of facility.

Recently rapid urbanization facilitates development of high-rise building complex including apartment and office building in urban area. Many problems related with high-rise building are reported. Especially, unpleasant strong winds in pedestrian area are frequently encountered around the high-rise building. CFD simulation methods are used to analyze the wind environment of pedestrian level in high-rise building block. However the results show differences between CFD and measurement. The reason for the difference is that conventional CFD simulation couldn't consider the effect of trees, shrubs and plants which affect the wind environment. Canopy model is a solution to solve the limitation of CFD analysis. In this paper, the canopy model to predict wind environment of pedestrian level by CFD simulation will be proposed and the validity will be analyzed by comparison of measurement and CFD prediction.

The purpose of this study was to evaluate and to analyze the spatial composition by block plan of the free elderly facility and to provide basic information for building up the detail architectural guidelines. The results of the study were as follows: Elderly welfare law needed to control the poor physical environments of the free elderly facility such as the residential space for more than 4 individuals. The facility of single building type should strengthen the informal support networks through the dispersion of public spaces or should encourage moving of the residents through the outdoor space, especially in rural area. On the other hand, the linking type needed to focus on the administrative spaces on the first floor for the managerial convenience, and to group and disperse the public/recreational spaces to decrease the unnecessary moving of the residents and staffs. The passageway linking building to building should directly connect each administrative space or public space so that elderly used them without any inconvenience. In the dispersion type, which is suited to rural area, the lounge, dining hall, and the place for the staff on duty should be located in the same as the residence building for the convenience and the safety of the elderly residents.

Due to the increasing concerns about the buildings which have affected the global environment, most countries have enacted a regulation for the sustainability of domestic buildings. In 2008, the Korean government started to enact a regulation of apartment and office buildings for energy saving. Many research on the sustainable apartment building focuses on $84m^2$ or larger type in response to market demand; therefore, small size type such as $46m^2$ type needs to be researched. In addition, the research on the orientation and window to wall ratio of the building have been separately studied as a means of energy reduction; therefore, the research on correlation of the orientation and window to wall ratio hasn't been fully explored yet. This paper analyzes the energy demand of the apartment building as the change of orientation and window to wall ratio among $46m^2$ and $84m^2$ type. In conclusion, when reducing the window to wall ratio, energy demand was reduced, except when the orientation of the building was between from +10 to -20 from the south.

In this study, specific sections vulnerable to debris flow damage were selected, and a complete enumeration survey was performed for the sections with debris flow hazards. Based on this, the characteristics of the sections with debris flow hazards and the current status of actions against debris flow were examined, and an efficient installation plan for a debris flow damage prevention method that is required in the future was suggested. The results indicated that in the Route 56 section where the residential density is relatively higher between the two model survey sections, facilities for debris flow damage reduction were insufficient compared to those in the Route 6 section which is a mountain area. It is thought that several sites require urgent preparation of a facility for debris flow damage reduction. In addition, a numerical analysis showed that for debris barriers installed as a debris flow damage prevention method, distributed installation of a number of small-scale barriers facilities within a valley part was more effective than single installation of a large-scale debris barrier at the lower part of a valley.

Recently, rapid development of technique and change of lifestyle during nighttime has activated the urban outdoor lighting and renovated consideration of nightscape. As the interest of nightscape increases more widely, outdoor lighting has been installed more and more in the cities. Nightscape comes in diverse forms. So, there is no absolute standard for outdoor lighting. But only bright outdoor lighting is not necessarily a good nightscape. Installation lighting without master plan or excessive outdoor lighting may cause a inharmony. This study aims to analyze the luminous characteristics of facade in shopping complexes. For the purpose, four large-scale shopping complexes located in Dongdaemun area were selected. Building facade composition, outdoor lighting composition, and lighting equipment of each shopping complexes are surveyed, and luminance of building facade were measured with Prometric 1400. The result of the study are as follows; (1) Horizontally large-scale shopping complexes emphasize the building entrance and shape of the building at night by outdoor lighting. (2) Non cut-off luminaries installed in building entrance and shop front caused the potential of light pollution.

The flood damage shows different types in natural river watershed and in urban drainage watershed. In recent, increasing of the impervious area gives rise to short concentration time and high peak discharge comparing with natural watershed and it is a cause of urban flood damage. In this paper, we use a XP-SWMM model developed based on EPA-SWMM version for analyzing the inundation area, inundation depth and inundation area considering building effect. The two events(2005.06, 2005.07) has been used for the validation of model. HEC-RAS model has been applied for simulation of changing water level, and the results has been used for calculating area of the inundation. The observed inundation area(21.41 ha) in August, 1998 was in good agreement with the simulated value(23.45 ha) of XPSWMM model. An influence of inundation area considering building effects has been analized by the DTM of XP-SWMM model.

Among the energy consumption in building, the heating energy takes the largest part. Therefore, it is important to minimize the heat energy loss in building for the reduction of overall energy use in construction. The most important points for the minimization of energy loss in building are insulation and airtightness. Especially, in wood houses, airtightness is very important for energy saving as well as increase of durability. However, the researches on airtightness of wood buildings have been started recently and are very deficient especially in Korea. In this study, air leakage properties and airtightness performance were evaluated for light-frame wood houses built in Daejeon and Chungnam area. Total 7 houses were evaluated, among which four houses (Case 1 to Case 4) were in the construction stage before interior finish and the other three houses (Case 5 to Case 7) were after completion of construction work. The tests for airtightness were conducted by pressurization-depressurization method, and the factors included in the measurements includes air leakage rate at 50 Pa (CMH50), air change rate at 50 Pa (ACH50), equivalent leakage area (EqLA) and EqLA per floor area. As a result of this study, key air leakage points in wood houses were found to be the gaps between floor and wall, the holes for wiring and plumbing, the double glasses windows and the entrance doors. The average value of ACH50 for the houses after completion of construction work was $3.5h^{-1}$ that was similar to Europe standard ($3.0h^{-1}$). ACH50 was proportional to EqLA per floor area but inversely proportional to the internal volume, the net floor area and the area of window.
