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.

This paper presents results from analysis of architectural plan drawings of 355 elementary schools recently designed for 4 years. Theses plans are analyzed by factors such as local distribution, number of classes, type of plan, total construction area, area per a class, area per a student, and area status of each space. The purpose of this study is to provide fundamental resources for architectural designing and planning of elementary schools through finding trend and status of elementary school buildings that have no detailed data of area index. The results of this study are as follows: 1. As a result from analyzing number of classes in the surveyed schools, schools having 36 classes are dominant and schools having 72 classes are also shown. Average number of classes is 34.1. This result reflect s that elementary schools have been planned as large-scale schools. 2. In terms of type of plan, we found out that instead of disappearing traditional single corridor type building, the open school building that have multi-purpose spaces are mainly designed. In addition to that, there are few schools with large class rooms. 3. In the status of area of each school, they have much larger areas than areas provided by building guidelines. Secondly, there are some schools with two times area difference even though they have same class number. Therefore, it needs to adjust the school building guidelines to practical needs in the consideration of elementary school building for compulsory education. Though the plans of recently designed school for 4 year s are more differentiated than past, there are few schools planned by appropriate plan design and area distribution scheme. As a consequence, some improvements like improvement of building guidelines are desperate.

New methodology is proposed to predict the hourly cooling load of the next day using maximum/minimum temperature and building area. The maximum and minimum temperature are obtained from forecasted weather data. The cooling load parameters related to building area are set through a database provided from reference buildings. To validate the performance of the proposed method, the predicted cooling loads in hourly bases are calculated and compared with the measured data. The predicted results show fairly good agreement with the measured data for benchmarking building.

Recently, it is becoming increasingly difficult to ignore carbon emission implication of building operations due to the significant rate of energy usage in buildings. In the building sector, our normal expectation implies that large building floor area induces more greenhouse gas (GHG) emission. In this research, the correlation between building total floor areas and GHG emission was explored by simple linear regression and analyzing the yielded residuals for confirming this seemingly obvious conjecture. By looking at the generated regression lines drawn based on the data sets representing public facilities in Ontario, Canada, we were able to confirm that carbon emission rate shows a proportional increase or decrease depending on the total floor area of buildings as has been implied as a conjecture. Some buildings were found to emit significantly large and small amount of GHG, and we addressed potential reasons why those buildings show the deviation from the confirmed proportional interrelation between a building's total floor area and the amount of GHG emission.

This study explores changes of industrial scales and building activities in the semi-industrial area of Seoul's Seong-su, responding to the shifts of industrial structures and policies in the Korean society. The purpose of this study is to investigate patterns of construction activities of factory buildings in the Seong-su semi-industrial area by analyzing changes in industrial facilities. As a result of the analysis, the change of the factory building area come out from the recent survey implies the possibility of entrepreneurial inflow as much and the new constructions and some remodeling cases which are characterized by complexity seem to correspond to the industrial structure. However, it is unreasonable to believe that this phenomenon is a mainstream movement involving small-scale factory buildings and companies. This is because there are aspects that are not included in this movement, such as changing the use of buildings without accompanying physical changes. On the other hand, compared to various movements of individual companies in response to the industrial structure, the physical plan suggests a limited alternative centering on the floor area ratio and the building area ratio. This means that the efforts to attract and grow the power of knowledge based-industry through the designation of the Industrial Development Promotion District in part of the case sites, overlook the natural change through remodeling and reuse of existing buildings. In addition, considering the fact that the production space of industrial use can be greatly influenced by the behavior of users compared to general buildings such as residential and commercial, it is necessary to pay attention to various phenomena occurring in the area more locally than the uniform supply policy. Based on these findings, this study contributes to illuminate the legal system related to building act in the Seong-su semi-industrial area and the potential direction of architectural suggestions in related policies and researches.

농촌의 공동이용건축물은 시대에 따라 그 수요가 변화해왔고, 그에 따라 기능과 규모 등도 바뀌고 있지만, 농촌지역에 반드시 필요한 시설이라는 점에서 중요하다. 하지만, 주로 농업생산기반시설에 초점이 맞춰져 있어, 도시지역에 비해 의료, 보건, 문화, 교육 등의 건축물은 턱없이 부족하다. 이에 본 연구에서는 농촌주거지역 내의 다양한 공동이용건축물을 조사하여 현황을 파악하였으며, 추가 검토를 통해 문제점을 구체화하였다. 그리고 건축물 별 상황에 따라 재생방안을 제시하였다.

3차원 지도(3D Map)를 구축하기 위해서는 지형정보와 지도상에서 건물 영역 및 건물 형상 정보가 필요하다. 이를 위해 본 논문에서는 개선된 스네이크(Snake) 알고리즘으로 건물 영역을 반자동으로 추출하는 방법을 제안한다. 본 방법은 전처리, 제어점의 초기화, 개선된 스네이크 알고리즘 적용 세 단계로 구성한다. 첫 번째 단계에서는 위생영상을 그레이 영상으로 변환 후 근사 에지를 추출하여 그레이 영상과 합성한다. 두 번째 단계에서는 사용자가 건물의 중심점을 설정한 후 원형 또는 사각형 모양의 초기 제어점을 계산하여 설정한다. 세번째 단계에서는 개선된 스네이크 알고리즘을 적용하여 건물영역을 추출한다. 이러한 과정에서 스네이크 에너지 계산식의 한 항을 새로운 방법으로 설정하여 건물영역 추출용으로 특화하였다. 그리고 스카이 뷰의 위성영상을 이용하여 제안된 방법을 건물영역 매칭율을 평가하였는데 75%의 매칭율을 보였다.

본 연구는 해당 지자체의 전체 건축물중 시가화구역 내에 건축물이 얼마나 집중하고 있는지를 조사하였고 이를 '건축물 시가화집중도'라는 용어로 처음 사용하였다. 경북의 각 시군에 대하여 건축물 시가화집중도를 조사한 결과 건축물 시가화집중도가 낮을수록 노인인구 비율이 높으며 지자체의 주민 1인당 일반회계 지출액도 많은 것으로 나타났다. 본 연구를 통해 건축물 시가화집중도가 도시쇠퇴 정도와 도시재정의 효율성을 가늠할 수 있는 하나의 지표가 될 수 있음을 확인하였고 향후 축소도시계획 수립에 필요한 기초자료로 활용될 것으로 사료된다.

Optimized capacity of equipments are essential for energy saving and low cost construction and operation. So we must use proper design data for HVAC system design. We investigated for architectural data, equipment capacity, cooling and heating load design criteria of 52 office buildings. Following research results were obtained by carrying out each task. Office building effective area rate is 63%. The average building cooling load of South Korea is $140W/m^2$ and average heating loads in Seoul and Pusan area are $120{\sim}130W/m^2$ and $70{\sim}80W/m^2$. We also analysised HVAC design criteria. Person ratio in effective building area is $0.2person/m^2$, sensitive and latent heat loads of a person are 60W and 65W, light and equipment loads of office buildings are $25W/m^2$ and $20W/m^2$.

Recently, ecological area rate system become effective due to enlargement of recognition and high intellectual standard and for ecological circulation in urban areas. Ecological area rate system is to control environmental quality of life what has grown worse in urban districts and corresponds to purposes of green building certification criteria for environmentally sound and sustainable development. Therefore, purposes of this study are to present suggestions through research of theory and comparison between ecological area rate system and green building certification criteria.
