Most of solar panel support structures have made as flat-type. But, these structures can not be harmonized with the variable shape of existing buildings. Therefore, this study presents the curved support structures. Also, the evaluation of the structural safety of curved support structures is performed through modelling and analysis of structure.

Korea proceeded rapidly since the 1960s, economic development, urbanization, most of the people living in the city. Rapid urbanization and enrich the life of our country to the fact that, arising out of the use of fossil fuels, which made possible the industrialization and urbanization of air pollution and climate change, the depletion of energy sources, such as the negative effect resulted.The purpose of this study, according to the urban spatial structure plan for a regional energy plan to investigate the energy efficiency and sustainability in terms of the nation's urban planning.

Aerogel has largely been used as insulation for the spacecraft and industrial facilities. As the building energy saving is more and more important, high-performing insulation like Aerogel will be required in buildings to improve their thermal environment and to save building energy. In case of reinforced super-insulation, the existing resistive insulation should be used as thick as 250mm, but Aerogel could meet the same performance with half thickness of 120mm. Thanks to the reduced thickness of insulation, Aerogel has the advantage in applying to high-rise buildings and it is believed to gather the interests of construction companies which have difficulty in solving the strick insulating problem.

The energy saving of HVAC that is the occupiest on office building is being more important. In office building, CAV and VAV are adopted very much. Therefore, on this paper, we compared with VAV and CAV focused on energy consumption by using dynamic energy simulation. For objective comparison, after we chose standard building, found building that is closed to our standard building, we simulated. During seasonal cooling period June, July, August, September, the result of CAV and VAV energy uses were 34969.44kwh/m² and 27212.77kwh/m². Baesd on this result, we could find VAV is more energy effective as much as 7756.68kwh/m² than CAV.

In these days, industrialization-house of interest also was increased. However, an industrialization house, using the steel-stud in structure, causes the problem which is a heat-bridge that was decreased an insulation performance on entire buildings. So, recently, a regulation regarding an industrialization method house was coded a court, and an insulation performance examination of the existing industrialization house became necessary according to laws. In this study, we used Physibel Bisco by parts to present at regulations, in order to review insulation performance of the existing industrialization house, and we act up to simulation. And derive from the results, a basis of insulation performance to have tried simulation that was suitable.

Urbanization in Korea has been on the rapid progress, and reached almost 80% in 2000. The phenomenon has caused a reduction in greens and environmental issues. This researcher analyzed land cover maps of the entire region located at Seo-gu, Busan, with the lapse of 10 years in 2002 and 2012 and land cover changes of the two years to look into quantitative and qualitative changes. Therefore, this researcher tries to make a basic investigation on time-series data update of E-GIS DB that will be able to be used as a fundamental material in estaliblishing urban planning.

The advent of IT and display technology provides new possibility that we can use the digital images with pixel values of brightness to figure out the exact value of luminance in the visual environment. For this purpose, a certain DSLR camera has been calibrated to take a photolux image with real value of luminance. To verify the practical usefulness of the image processing technology with the specific digital camera, a comparative study with physical measurement values of brightness on a window of an apartment house has been performed. Not surprisingly the image processing approach delivers a set of accurate luminance values on a certain area of the window.

Jeju island is an area where strong winds blowing throughout the year, so they tried to stable airflow environment both inside and outside buildings by stone walls as components for windproof. However, today stone walls does not perform a role occur frequently why people are lack of understanding and misconceptions about function of the stone walls. Therefore, in this paper, we studied the impact of Jeju stonewalls on outside air environment through functional analysis such as the simulation and suggested plan for placement of the stone walls.

This research has developed a GWHP system that employs a hybrid heat pump system with groundwater wells using multi heat source, groundwater and air source. This paper describes about real-scale experiments using a standing column well (SCW). The heating and cooling experiments have been conducted at at Nagoya site where the groundwater level is 4 m depth and the quality of groundwater is not good. The SCW has two screens which divided by a packer and the system can automatically switch the positions of pumping and returning. The coefficient of performance (COP) of heat pump and system was calculated by the temperature of groundwater and the pumping rate. In the results, system COP of cooling was 6.5 and it of heating was 3.6.

The purpose of this study is to enhance sound insulation of a window by discovering its exact location where sound is leaked out. Referring to KS F 2808 Korean Industrial Standard, the experiment was run by reinforcing either the gap between windows or the interior of a window frame in order to produce the optimal efficiency. It turned out that the higher sound insulation was resulted from the enhancement of the material on the gaps between windows.

In this study, through surveys to identify and evaluate the optimal building layout about tower-type apartment complex that people prefer to prospect right. The result of study can be summarized as follows- 1) Survey results, considering the prospect right that choosing the residential selection rate was at a low level, but 90% answered that people needs for the necessity of prospect right to verify the necessity of considering the prospect right. On average of apartment view that can satisfy the minimum is about 40.7%. 2) The simulation results, square layout>oblique line layout>right angle layout appear of the order. So square layout showed to be the most favorable at average view rate.

Today, as our industries and businesses is almost dependent on electric apparatus or on-line system, management system of electric facilities is necessary to be considered as the part of the maintenance of the building. Also, facilities of power supplies can't always provide stable power service because of various situations of blackout caused by natural disaster, construction of extension building or remodeling building. So a study of emergency power system is required. Therefore, we will research the communication facility so that we are going to study the emergency power equipment of Buildings, and analyze the importance of emergency power equipment depends.

In this paper, the phase change material (PCM) to increase the heat capacity of buildings is applied to building materials. The building materials use not only sensible heat but also latent heat so that the building materials are useful to maintain the pleasant indoor environment and to save the building energy. The model experimental research results are as follows. (1) The test shows that the sheet or pipe type heat storage materials are effective to reduce the daily temperature range, rather than the standard type. (2) The sheet type material has better capacity than the pipe type material to delay the increase in indoor temperature. (3) The building material mixing the phase change material can be useful to maintain indoor comfortably.
