본 연구는 야간조명 하에서 수목이 효율적으로 생장하는 방법을 모색하고자 LED 색온도에 따른 광합성 전자전달 효 율을 검증하였다. 가로수와 조경수로 도시환경에 많이 식생하는 겹벚나무를 대상으로 White 색온도를 비춘 수목과 Warmwhite 색온도를 비춘 수목, 그리고 무처리 수목을 대상으로 건전도를 비교하였으며, 연구방법으로는 엽록소 형광 반응 (OJIP)을 활용해 LED광원 색온도 조건에 따른 광 스트레스 광생리지표 분석을 통해 광화학반응 해석과 건전성 평가를 하였다. 엽록소 형광반응 (OJIP)을 분석한 결과는 모든 처리구에서 처리 후 115일인 생육후기로 갈수록 낮아졌으며, White 광처 리구와 Warmwhite 광처리구에서 J-I구간의 전이 과정 중 생육후기의 형광량이 증가하여 광계I전자전달효율은 감소된 것을 알 수 있었다. 따라서 전자전달효율인 RE1O/CS 및 RE1o/ RC 모두 감소되었다. 이 중 White 광처리구는 Warmwhite 대비 형광량의 증가폭이 컸으며, PITOTALABS는 처리 전 무처리에 비해 가장 높은 수치였지만, 115 DAT에는 가장 낮은 수치로 감소된 것을 알 수 있었다. 본 연구를 통해 White 광을 비춘 수목은 전자전달효율 및 건전도가 낮은 것으로 판단되었으며 상대적으로 Warmwhite 광처리구의 스트레스가 더 낮은 것으로 나타났다.

As the balcony expansion of residential building was legalized, the expansion generation is tend to increased continuously of existing residential building or condominium complex. But balcony is the service area. So, it is worried about defect occurrence of extension construction because thermal insulation effect is insufficient to balcony installed an aluminum sash. Therefore, it is desired the method to minimize the damage of performance improvement of the windows which has an influence directly on the performance defect. See-through a-si is effective to reduce the cooling loads and sunlight, to produce the electricity by installing a-si at the wall and windows of residential building. This paper has predicted producing electricity and have analyzed heating/cooling load based on balcony expansion and building-integrated PV installation in residential building.

I selected a hypermarket as a research target by investigating energy consumption and total area of each 11 hypermarkets and suggested energy saving key elements by analyzing the cooling and heating loads. I completed a calibrated simulation model by searching literature, site survey and dynamic simulation tool. I separated the energy-saving elements into architectural and facility sections by searching domestic standards as well as theses, and applied those elements to the calibrated simulation to calculate the energy consumption. Then I suggested energy saving elements that suitable for the hypermarkets by comparing each energy consumption of architectural and facility sections.

With the development of artificial lighting technology, human can breakout the limitation of the natural light and make it possible to create a brilliant civilization. However, the wide used outdoor artificial lighting caused severe environmental problem called "Light Pollution" due to human's less cognition of using light and excessive light. Obtrusive light at nighttime can do harm to the human health and observation activity. In this paper, the upward light control process of general lighting fixtures was suggested for reducing the adverse effects such as sky glow in the central city and light trespass in the residential areas.

Environmental lighting zone-setting has suggested regulatory standards according to the influence of artificial illumination on natural environment and human life. Then, it is necessary to check out the viability of environmental lighting zone division as it is limited to use-zone division. This study aims to suggest some problems, which occur when environmental lighting zone is set by use-zone only, by comparing and analyzing the artificial illumination luminance. In addition, this study aims to suggest basis for the environmental lighting zone-setting and eventually, more effective environmental lighting zone division.

This study fouces on the electricity generation of B1PV system in the super-tall buildings. To improve the efficiency of the B1PV system, solar irradiance and air temperature should be taken into consideration. This study does research on, one of two main parameters, the solar irracliance in the super high-rise buildings. According to the measurement of solar irracliance, it increased with altitude. It is, particularly, more obviously in the super-tall buildings than others. Subsequently, to make an accurate B1PV elecrticity generation prediction，it is necessary to anaiyze the solar irracliance distribution on the super-taII building's facade which is a prerequisite for optimal B1PV system design.

The paper mainly discusses on the method how to save energy so as to follow the "Low Carbon and Green Growth" by the govemment and the Building Energy Efficiency Rating System. For the purpose of interior comfort as well as effective operation and management of buildings, this paper does basic research on development of elementary technology for saving the energy used in building. In this paper, the interior lighting control zone is selected to make a lighting control algorithm which takes the reduction of building energy into consideration for saving building energy when the building envelopes are replaced by the BIPV system.

Light pollution is a side effect of industrial civilization. It obscures the stars in the night sky for city dwellers, interferes with astronomical observatories, and, like any other form of pollution, disrupts ecosystems and has adverse health effects. It is most severe in highly industrialized, densely populated areas of North Arnerica, Europe, and Japan. Nowadays, light pollution has become a global problem and the public concerns on disputes of light pollution have been on the rise. Unfortunately, we haven't had any comprehensive and systematic regulation of lighting pollution yet. Therefore, we need to make our own regulation of lighting pollution to deal with it. The purpose of this study is making a research on the standards and countermeasures of light pollution at home and abroad before establishing our own regulation based on which we can resolve and reduce the light pollution.

This study was carried out to evaluate the Life Cycle Cost(LCC) of four types of BIPV(Building Integrated Photovoltaic) systems -Glass plus Granite, Crystalline BIPV, Crystalline BIPV + Glass plus Granite and See through Amorphous BIPV -which were vertically installed to generate the same capacity(2kW) and the same area. Initial investment costs, cost savings and maintenance costs had been predicted during the period of analysing the LCC of four types of BIPV(Building Integrated Photovoltaic) systems installed for the purpose of evaluating the LCC. In case of cost savings, it had been analyzed by measuring the amount of electric power generated, reduction in lighting load and heat & cooling loads through simulation. From this analysis, it was predicted that the See-through amorphous BIPV offering cost saving advantages demonstrated the economical efficiency similar to the Glass plus Granite when it is backed by more than 20 years of durability.
