The purpose of this study is to provide foundational data for expansion of solar generation in building application, a clean energy, by introducing applicability of solar power generation system on roofs of industrial buildings and computing expected amounts of power and carbon dioxides reduction. As methodologies of this study, after reviewing 120,000 domestic factories to verify the BIPV feasibility for industrial building sthrough theoretical considerations of solar generation system, we calculated BIPV application methods and subsequent expected power generation quantity and carbon dioxide reductions through roof type analysis. we analyzed four cases of expected power generation amounts of solar batteries according to application methods, and when considering that the main type of roofs are slant roofs according to the investigation result about roof forms of domestic industrial complexes, we believe that the module angle of a slant roof around $17^{\circ}$(case3) is most suitable for the application. Finally, we came up with 517,944[TOE] as the corresponding petroleum tonnage based on this computed expected power generation amount and the amount of 1,214,836[$tCO_2$] carbon dioxide reductions by calculating them by energy sources.

Purpose: The purpose of this study is to develop and apply an environmental impact assessment program for apartment building elements, based on the building materials of the LCI DB, which can link the LCA results of building materials and buildings. Method: For this purpose, a framework for building elements was established, and several building material combinations were developed. In addition, the LCA method for quantifying environmental load emissions from the building materials of each site was applied to establish an environmental impact database of the building materials of the LCI DB. Result: An environmental impact assessment program, based on a Microsoft Excel worksheet, was developed for apartment building elements. This program can link the environmental impact assessment of building materials and building units. To validate the program evaluation results that were obtained in this study, a comparative analysis was carried out using the results of existing evaluation methods. The error rate was estimated to be 5% for environmental impact assessment using existing evaluation methods.

건물에너지 자립과 온실가스 배출 저감에 BIPV 역할이 증대되는 가운데 기존 결정계의 한계를 극복할 수 있는 DSC의 적용이 주목받고 있다. 특히 DSC의 다양한 색상과 투명성 그리고 방향에 무관한 작동성은 모듈의 다기능 복합재로서 BIPV폭을 크게 확장시킨다. 이에 사례조사 분석을 통해 DSC BIPV의 가능성을 살펴보고 그 활용성을 조망한다. 국 내외 각 3건씩의 사례 조사 분석을 통해 나타난 대부분의 DSC BIPV는 주로 창호와 차양 장치로 구현되고 있고 이는 DSC의 특성과 무관치 않다. 즉, 다양한 색상과 투명성의 모듈은 건물 외피디자인과 에너지 획득에 커다란 전환점을 마련하고 있는 것으로 파악된다. 한편으로는 적용모듈의 색상으로 인한 눈의 자극성이 존재하여 BIPV 창호적용에는 건물 및 실의 용도에 따른 색감 고려가 필수적이고 건물외피 적용을 위한 유연한 모듈개발의 경우 DSC BIPV는 상당히 기대되는 확산성을 가질 것이다.

This study aims to present the applicability of wind turbine generator system to urban buildings for the utilization of clean renewable energy. The results are as follows; According to the wind resource analysis, it has been found that small sized wind power system can be viable for buildings application due to the amplification of wind velocity around buildings or building clusters, in spite of low mean velocity of 2-3m/s in Seoul and Kyunggi urban areas. But planners must perform micrositing analysis around building so that wind turbine can be located at high velocity zones. The system must be designed to avoid obstacles preventing prevailing wind in buildings. It should be recognized that wind speeds are changing depending on the height and length from buildings. The wind power system can be used as a symbol of landmark which shows a sustainable architecture from the scenary Itself A case study for apartment building in urban showed that wind power systems can be applicable in two kinds of place, rooftops and ground levels. Especially, the wind power systems must be carefully positioned so that wind resources do not decrease when it is installed at ground levels. and according to life cycle cost analysis, adaption of new small win4 power systems to buildings were proved to produce a profit if it is considered the expense of environment improvement and the wind speed increasing according to rise of building height. This research will ultimately achieve green architecture that preserves nature and at the same time provides pleasant environment to humans, and will play a great role in establishing the environment-preserving sustainable architecture of the 21th century.

This study examines the risk of overheating of a school building, under extreme hot weather conditions, in 14 locations in the United Kingdom using the overheating criteria defined in Building Bulletin 101 (BB101). The building was modelled as naturally ventilated, mechanically ventilated and in mixed mode and was simulated both for the current and the projected weather conditions of the 2050s. Under the current weather conditions, results of the simulations show that when naturally ventilated, the school building fulfils the BB101 criteria only in the areas of Edinburgh and Glasgow. In the simulations of the building as mechanically ventilated and in mixed mode, mechanical cooling was provided in order for the building to comply with the overheating criteria. A comparison of the required cooling loads between the two scenarios shows that application of mixed mode ventilation results in less cooling loads.

The application of photovoltaics into building as integrated building components has been paid more attention worldwide. Photovoltaics or solar electric modules are solid state devices, directly converting solar radiation into electricity; the process does not require fuel and any moving parts, and produce no pollutants. And the prefab building method is very effective because the pre- manufactured building components is simply assembled to making up buildings in the construction fields especially the sandwich panel. So, the purpose of this research is to integrated prefab building materials depending on the cooling type of PV modules. It is concluded that the prediction of BIPV system's performance should be based on the more accurate PV module temperature. From the basis of these results on the correlation of temperature and irradiation were obtained.

Vibration issue of a building structure due to a wind turbine should be resolved for the application of building-augmented wind turbine. In this study, a dynamic analysis for an horizontal-axis upwind wind turbine is carried out to calculate vibration excited to an example building structure. Characteristics of vertical vibration transfer of the building structure are analytically studied and compared with a criteria. Then, a method to isolate the vibration is presented by analyzing the vibration characteristics of the wind turbine, and verified by applying to the building structure.

This paper describes probabilistic characteristics of damping in a tall building based on the results of full-scale measurement. It is found, through statistical analysis of the damping data, that the probability density function(PDF) of damping at the high amplitude plateau can be well represented by Normal distribution (Gaussian distribution). A stochastic damping model is proposed to estimate amplitude-dependent damping for practical application.

According to the climate change and the improvement of income level, floating building on water has been emerging as a strong alternative. This study was intended to suggest some reference materials of sustainability for new floating building projects. The concept of sustainability and floating building was investigated, and 3 realized projects and 3 planned projects were reviewed in terms of sustainability. Sustainable features of the sample projects can be summarized as recycled and relocatable usage, adoption of various renewable energy techniques, installation of self-supporting plant, application of modular system and others like new material & open layout. Sustainable features need to be developed more and more in detail and applied to many types of floating buildings.
