Recently, energy saving in building sector is of great important to meet national $CO_2$ reduction goals in Korea. In this sense, it is crucial to improve the energy performance for existing building. The energy efficiency investments, ESCO business, can be beneficial to expand the chance of energy retrofit for existing building. However, ESCO business hardly expand in Korea because it has many limitations in guarantee for energy saving. Also, it is more difficult to apply the energy retrofit measures in existing building than new building. Therefore, the retrofitting methods for existing small-and medium-sized buildings should be improved to initiate ESCO business and expand it in Korea. In this study, the energy retrofit methods for small sized office building were suggested and the case study for a small sized office building located in Suwon was accomplished.

Each country has implemented various environmental policies to prevent natural disasters and destruction of ecosystem caused by global wanning. The republic of Korea also was performed building energy efficiency rating certification system as part of paradigm of 'Low carbon green growth' since 2010. However, the status on the building energy efficiency rating certification system has not been analyzed. In this study, We analyzed the elements affecting the energy efficiency of small office buildings focusing the status and certification cases of the building energy efficiency rating system. As a result, it is judged that thermal performance contribution of the building envelope is not high in the buildings certificated the first grade of the building energy efficiency rating system.

The performance of the daylighting in buildings depends on building site and shape. As an energy saving design strategy, daylighting is a key issue in green building design. In this paper, the influence of the adjacent or obstructed building on daylighting performance of the office building in urban area was analyzed. A typical office building about 20 storeys with obstructed buildings has been modeled and simulated using Radiance. The parametric simulations have been performed to analyze the influence of the daylighting performance (illuminance, luminance) of the analyzed office. The results show that the possibility of the glare was decreased when the obstructed building is located in south, also the illuminance level was significantly decreased. When the obstructed building is located in north, the changes of the illuminance level and luminance possibility were somewhat small compared to the unobstructed condition. The daylighting performance of the analyzed building was most affected by the obstructed building in winter season.

Generally LED lamp has many advantages to compare with a general lamp, long life and no pollution matter like the mercury. Also it is excellence for color rendering and need to small consumption electric rower. However LED lamp has some disadvantages to compare to general fluorescent lamp and That is small light flux about 50% and narrow light distribution than fluorescent lamp. Therefore, to apply LED lamp in an office building, after analyze a illuminance distribution with an environment analysis and cooling, heating and light energy. The purpose of this study is to analyze light environment. light, cooling and heating energy simulation in Office building.

The former administration office building of Kyeong-seong-bu(京城府) was a building converted from the Japanese residency-general's of Kyeong-seong(京城理事廳) which was originally built as the Japanese consulate in Joseon(日本領事館). It was too worn and too small as a Kyeong-seong-bu administration office even with several annexes. Kyeong-seong-bu tried to build a new big administration office building at the vacant north side of the same site, which was closely faced to the rotary in front of the Bank of Joseon(朝鮮銀行前廣場). But this trial was ended in vain due to insufficient budget. Therefore Kyeong-seong-bu built a new administration office building in another site and moved to it in 1926 with debts. For paying for the debts Kyeong-seong-bu sold the former site after partitioning with new roads through it. As a result the nature of the former site and its surroundings was changed. This study traces the changes and inquires how the authorities in the colonial Joseon and various commercial powers of Kyeong-seong-bu behaved for their own interests in the meantime. It makes use of the historical records and documentary literatures between early 1910s and early 1930s.

본 논문은 LED 램프를 사무소 건물에 효과적으로 사용하기 위하여 새로운 통합적 에너지 시뮬레이션을 수행한 연구 결과이다. 일반적으로 LED 램프는 다른 램프에 비하여 에너지 절감효과가 매우 우수하지만 현재 형광램프보다 낮은 광속과 좁은 광분포 등 아직 사무소 건물에 적용하기는 다각적인 검토가 필요하다. 연구결과 냉난방에너지가 20[%] 증가하고 현재 형광등을 대체하기 위해서는 90[lm/$m^2$] 이상으로 설계해야 한다. 따라서 LED램프를 사무소 건물에 적용하기 위해서 광에너지, 냉난방에 미치는 영향 및 사무실환경에 미치는 광분포를 통합적으로 해석하였으며 앞으로 이 결과는 LED 램프를 통한 효과적인 에너지절약 환경을 구축하는 데 중요한 자료를 제공할 것으로 확신한다.

This study is to inspect and analyse the historical background, spacial organization and architectural features about the traditional government office building of Gangwon Gamyoung(the supreme local government office of Gangwondo in Chosun dynasty). The results are as follows. - Gangwon Gamyoung was located at the center of Gangwondo in consideration of distance to each small local office. And also it was located in consideration of geographical connection between Hanseong(today's Seoul). - The spatial organization of Gamyoung was divided into the three parts of entrance space, government office building space and backyard space. The entrance space was composed of three gates(Pojungru-Jungsammun-Naesammun). The government office building Space was consisted of business and living building as center of Sunhwadang(the main office building). And the backyard space was composed of Yonji(pond), Jungja(bower), and so on - The way to enter the space of Gamyoung follows the order from Pojungru(the first & outer main gate with a bower), Jungsammun(the second & intermediate gate), Naesammun(the third & inner gate) to Sunhwadang at last. - There were a beautiful Yonji(pond) which to be rectangular type and to have a round island with Bongraegak(bower) at Gamyoung backyard, the drain conduit and pedestrian road covered with pebble in the ground.

The daylighting control system has to be applied to prevent the excessive incident daylight and reduce energy use. As the one of the most useful daylighting control systems, the blind system is simple and easy to install on the window for small office buildings. This study aims to evaluate the summer energy performance of small office buildings by venetian blinds and energy saving strategy of ministry of knowledge economy in korea. For the study, the simulations have been executed on blind installation conditions and lighting control methods. As results, the energy loads cut down 22 to 25(%) by using blind energy. Also, the efficient shows high on EMS system and low on $45^{\circ}$ slat angles. Also, using energy saving strategy can reduce about 13(%) energy load.

우리나라에 공공도서관이 많이 없다. 그 이유는 국민들의 공공도서관에 대한 중요성 및 필요성에 대한 인식 부족과 중앙 및 지방정부의 도서관건립에 대한 인색한 투자와 함께 효과적인 공공도서관 건립정책이 없었기 때문이다. 이제 선진국과 같은 작은 도서관 건립 및 운영 정책을 펴야 한다. 지역 재개발 및 아파트 재건축 추진은 이들 지역에 작은 규모의 마을도서관을 건립할 수 있는 좋은 기회이다. 서울에 있는 J아파트는 재건축을 추진하고 있는데, 이 시점에서 새로운 위치로 옮겨가는 동사무소와 우체국을 하나의 건물로 신축하고, 이 건물 내에 공공도서관을 설치할 수 있을 것이다. 도서관을 이들 시설들과 함께 1층에 배치한다면 시너지 효과를 발생시켜 세 기관 모두에게 도움이 될 것이다. 이처럼 재개발 및 재건축 지역에 공공기관 혹은 상엽시설과 함께 복합건물 형태로 작은 도서관을 건립하는 것은 우리나라 공공도서관의 부족 문제를 해결 할 수 있는 좋은 방법이다.

The purpose of this study is to calculate the energy consumption rate based on data regarding energy use in office buildings, and to confirm the general characteristics of energy consumption. The energy consumption rate of the building is calculated by dividing the energy consumption by the floor area. The energy consumption rate of small-sized office buildings was calculated as $101.48{\sim}201.55kWh/m^2{\cdot}year$ and in the case of medium-sized buildings, the range was $92.77{\sim}177.89kWh/m^2{\cdot}year$. In the case of small buildings, it was found that the energy consumption was $73.24kWh/m^2{\cdot}year$ in electronic device, $34.31kWh/m^2{\cdot}year$ in hot water supply, and $18.37kWh/m^2{\cdot}year$ in heating. In the case of medium-sized buildings, electronic devices was $73.08kWh/m^2{\cdot}year$, lighting was $18.35kWh/m^2{\cdot}year$ and heating, $15.37kWh/m^2{\cdot}year$. In all of the study buildings, the peak heating energy use was observed from 8:00 a.m. to 10:00 a.m during the winter, and the peak power management was required. Energy use at and around the midnight hour is confirmed to be 40~60% of weekly working hours, so it is necessary to manage power use at night time as well as during the day. In order to improve the accuracy of future studies, it is necessary to make efforts to secure the data with standardized energy measuring units for the various type of buildings.
