The global financial crisis resulting from sub-prime mortgage crisis in the United States, beginning in 2007, has had dealt a blow to domestic economy. The economic downturn, coupled with a large number of apartments remaining unsold has resulted in contracted investment sentiment of the builders. Thus it's difficult to even implement the business, unless the investment project is thoroughly verified as well as the accurate profitability is granted. Viewing the current situation, forecasting and evaluating the business profitability is more than important today. The study was planned to identify the factors influencing the business success and to evaluate the sensitivity, relative risk of each factor was measured, and the scope of the study was limited to the commercial buildings among other buildings except apartment buildings. Hence, the study was aimed to analyze the factors affecting the business and the sensitivity so as to be able to systematically materialize the risk management of the commercial buildings. The outcome of the study is expected to serve the useful data in analyzing the business profitability and implementing the investment projects as well.

In commercial areas, outdoor units are typically installed close to one another in the narrow space between buildings due to insufficient regulations. This makes it difficult to ventilate the discharge airflow, which may lead to deterioration of the performance of outdoor units. This study conducted CFD simulation to analyze the thermal environment according to the installation distance of the outdoor unit. The outdoor unit was installed in the space between buildings, and the thermal environment was analyzed by changing installation distance and wind speed. The performance of the outdoor unit was evaluated by measuring the on-coil temperature. The results show that the closer the distance between outdoor units, the higher the condenser on-coil temperature. Also, the on-coil temperature appeared to rise dramatically at lower wind speed.

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.

The purpose of this study is to present the problems of urban ecosystem imbalance in Seoul and the need to restore housing functions through comparison with Manhattan, New York, which grew earlier than Seoul and has been striving to solve urban problems and restore urban ecosystems. The residential status in urban commercial use areas was investigated through analysis of the total amount of residential space, characteristics of each type of residential building, and distribution of residential buildings. Through this, it can be seen that most of the space in Seoul's historic city center is biased toward commercial roads, and there are significantly insufficient high- and high-density mixed-use buildings suitable for urban dwellings compared to Manhattan's. In addition, it can be seen that the complex building in the historical city center of Seoul is located adjacent to the outskirts of the target site. In conclusion, Seoul's historical city center does not provide an appropriate residential space for creating an urban ecosystem, and it is necessary to come up with measures to restore housing functions.

The propose of this study analyze an expression method of a surface in commercial buildings, and it is to show an example of a surface design in Manhattan. In particular, I focus on the following three categories : representation element of surface image : materials and structure method, the property of transparency, and an electronic surface and media screen. Unlike the past era in which surface design in commercial buildings was viewed just as a mean ornament, it has become more important in the presently era because diverse expression technologies in surface design makes architects express there creative ideas. Besides, the diversity of surface design expands the concept of cultural space as it provides various graphic element that human desire for multi-cultures. So diversity of surface will accelerate.

건축법이 올 정기국회에서 개정될 예정이다. 이를 위해 건설교통부는 지난 7월 10일 입법예고 하고 법제처 및 관계부처 협의를 진행중인 것으로 알려졌다. 입법예고 내용중 상업지역 공동주택에 대한 일조기준 폐지 및 건축물의 일조기준을 남쪽기준으로 변경, 허가기준 고시, 피난 및 내화 등의 건축기준을 설계기준으로 고시, 사전승인대상(21층이상 10㎡이상)을 시도에서 직접 허가가능토록 하는 등 절차와 기준에 대한 대폭적인 변경이 예상되고 있다. 그러나 무엇보다도 일반인의 관심을 끌었던 것은 일간신문에서 중점보도한 "용도변경이 자유로워져 건축물을 마음대로 사용할 수 있다"와 "건축인허가시 건축사확인으로 허가 가능한 대상이 확대된다"는 것이었다. 따라서 용도변경제도와 허가제도의 개정 내용과 이를 시행시 발생하는 문제점과 함께 개선방안, 선결되어야 할 문제와 관련, 병행해서 개정되어야 할 과제 등을 살펴보고 바람직한 제도개선 방향에 대해서도 제안해 본다.

In the past, the rooftop was a place where a water tank was to be installed, and a space of secretion and concealment such as a warehouse exposed in the air. It was because it was judged to hinder the beauty of a city as a whole without having any functional value per se. However, the roof portion is increasingly being utilized for a space such as a cafe, a pub, and a lounge as the rooftop is highly recognized as a place for leisure activities other than an idle space in modern times. Nonetheless, there are no detailed ordinances and criteria corresponding to such circumstances. For example, in case of the rooftop space, the building code applied to the rooftop space is a legal system when the rooftop was an idle space in the past though people have now accessed more increasingly to the rooftop than in the past. This study investigated the definition on the rooftop space evolved in accordance with the change of the rooftop space and the related legal system in Korea, and conducted a survey for the purpose of performing the field investigation for the analysis of physical status in 117 spaces that form the rooftop space in the rooftop of small-scale commercial facilities with 2 stories through 4 stories in Korea and analyze the recognition of users and analyzing the recognition of users. We analyzed the problems in the rooftop space through analysis of derived data, and suggested improvement plans.

1. 2/4분기중 전국의 건축허가면적은 전년동기에 비하여 6.4$\%$가 감소하여, 1/4분기에 전년동기대비 12.3$\%$증가한 것에 비해 현저한 감소현상을 나타낸 바, 이는 건축허가제한 강화조치에 기인하는 것으로 보인다. 건축허가면적은 1월과 2월에 전년동기대비 각각 28.9$\%$, 18.4$\%$의 증가를 나타내었으나, 3월들어 1.1$\%$가 감소하면서 감소세로 돌아선 이후, 4월, 5월, 6월에 각각 0.2$\%$, 16.4$\%$, 0.6$\%$의 감소를 나타내면서 지속적 감소추세를 보이고 있다. 특히 6월의 경우 감소추세가 둔화된 사유는 ''90.5.15 건축허가제한조치에 따라 ''90년의 허가면적 자체가 대폭 감소한 데 기인한다. 2. 2/4분기중 허가면적을 용도별로 보면 주거용 건축이 5.6$\%$ 감소하였으며, 상업용은 17.1$\%$의 감소를 보였으나, 공업용은 제조업 분야의 시설투자활성화 영향으로 13.6$\%$의 증가율을 나타내고 있다. 3. 이와 같은 허가면적의 감소추세는 허가제한 강화조치에 따라 하반기에도 지속될 것으로 보인다.

종래 건축공조시스템의 에너지절감에 관한 연구는 대체로 사무시설이나 상업시설에 관한 것이었고, 산업 시설을 대상으로 진행된 케이스는 극히 적었다고 할 수 있다. 그러나 이번에 귀중한 실측자료를 입수할 수 있는 기회를 가지게 되었고, 이에 본고에서는 산업 시설의 열원 시스템에 도입된 고효율화 기술의 에너지 절감 성능에 대해 실측과 시뮬레이션을 통한 결과를 소개하고자 한다. (중략)
