지난 20여년간의 비약적 경제 성장을 통하여 우리 사회는 모든 물리적 측면에서 양적인 성장과 질적인 발전을 거듭하여 왔다. 이러한 경제 성장기를 거치면서 우리의 삶은 다각도에서 변화를 겪었으며 건축환경에도 많은 변화가 있었다. 정보화, 세계화라는 시대적 흐름은 우리의 생활자체를 급속도로 변화시키고 있으며 업무용 시설을 포함한 모든 건축물이 대형화, 고층화 뿐 아니라 정보화, 현대화되고 있다. 그러나, 교육의 중요성과 이를 뒷받침해 줄 학교 시설의 중요성에도 불구하고 교육환경의 질적 개선은 상대적으로 낙후되어 있는 상황이라고 할 수 있다. 교육개혁위원회의 교육개혁방안이 계속적으로 나오고 있고 서울의 불암초등학교를 필두로 한 시설 현대화 시범학교가 시도별로 마련되고는 있지만 전반적인 교육 환경은 아직 열악한 상태이다. 특히 구도심부에 위치한 초등학교의 경우, 준공된 후 30년 이상 경과된 학교 건물을 사용하고 있는 경우가 적지 않아 안전상의 문제마저 안고 있는 실정이다. 따라서, 건물의 내구 연한이 그 한계에 달해 가고 유지보수비용이 계속적으로 늘어 경제성을 잃어 가고 있는 학교들을 대상으로 한 재건축과제가 신설 학교의 신축 또는 기존학교의 이전 못지 않은 주요 과제로 대두되고 있다. 더욱이 기존 학교의 재건축사업은 수업을 진행시켜가며 철거 및 신축공사가 단계적으로 수행돼야 한다는 어려움을 갖고 있다. 본 연구는 초등학교의 재건축을 위한 기본적인 자료를 정리하고 배치 및 평면 계획을 중심으로 한 계획 대안을 작성, 검토하여 대안별 장단점을 분석한 후 가장 바람직하다고 평가되는 안을 제시하는 것을 연구의 범위로 하였다. 계획안의 작성에 앞서 실시된 문헌조사 및 실측조사를 통하여, 신축되는 홍파초등학교에 필요한 시설의 내용 및 규모가 산정되었는데 특기할 사항은 좁은 대지임에도 불구하고 가능한 체육관 시설을 포함시키고자 하였다는 것이다. 홍파초등학교 부지는 $8,960m^2$ 정도밖에 안되는 좁은 부지로서 운동장도 제대로 확보할 수 없는 상황이었으나 체육관의 높은 활용도 및 장래의 필요성을 고려하여 소규모라도 계획되는 것이 바람직하다고 판단하였다. 열린교육에의 대응, 제반 특별교실의 확충, 식당 및 지하주차장의 확보 등 모든 시설이 현재 및 장차의 사용에 적합하도록 계획하여 현 시설의 1.5배 정도의 연면적을 갖는 신축 계획안을 작성하였다. 서울대학교와 광운대학교에서 분담하여 실시된 계획안의 작성을 통하여 총 4개의 계획안이 도출되었으며 이 대안들을 채광 및 환기, 학년별 zoning, 기능별 zoning, 열린교실의 정도, 지역사회에의 개방성, 재건축 공사의 용이성, 규모, 옥외공간의 활용성, 동선 계획, 조형성 등 10개 항목을 기준으로 평가하였다. 이러한 비교분석을 통하여 결론적으로 제1안을 최적안으로 제시하게 되었으며, 이를 바탕으로 구체적인 최종 설계안이 도출되기를 기대하는 바이다.

In this study, the effects of wind fences on the dispersion of the particles emitted from a constructing site located in the building-congested area in Busan, Korea, using geographic information system (GIS) and a computational fluid dynamics (CFD) model. We averaged the wind speeds observed for 10 years at the Busan automated synoptic observing system (ASOS) and we used the averaged wind speed as the wind speed at the reference height (10 m above the ground level). The numerical simulations were performed for 16 inflow directions, before and after the construction of wind fences with the heights of 5 m and 10 m (total 48 simulations). The detailed flows were analyzed for the northeasterly and south-southwesterly cases which predominantly observed at the Busan ASOS. In the northeasterly case, high concentration appeared at the elementary school next to the construction site due to transport by the airflow coming from the northeast. In the 5-m wind fence case, the wind speeds were slightly weaker and the spread of the fugitive dust was slightly less than those in the no wind fence case. In the 10-m wind fence case, the dust concentration at the elementary school has the maximum reduction of 37%. In the south-southwesterly case, the flow pattern became complicated in the construction site due to the terrain and buildings. Fugitive dust was stagnant at the south side of the construction site but rather spread to the north, increasing the concentration at the elementary school. After the wind fence was built, the concentrations inside the construction site became high as the wind speeds decreased inside, but, the concentrations in the elementary school rather decreased.

We measured PM2.5 and PM10 (particulate matter less than 2.5 ㎛ and 10 ㎛ in diameter, respectively) simultaneously at 16 locations around an elementary school and classrooms in Busan and Pyeongtaek, South Korea. In this study, we compared the results of this field intensive with those in the literature (144 cases of 30 studies), focusing on I/O (Indoor/Outdoor) ratios. We also reviewed the results of previous studies, categorizing them into related sub-categories for indoor-activities, seasons, building-uses, and the surrounding environment. We conclude that indoor PM10 is affected more by indoor-sources (e.g., physical activities) than PM2.5 in the absence of combustion sources like smoking and cooking. Additionally, PM10 and PM2.5 likely have different indoor-outdoor infiltration efficiencies. Conclusively, PM10 in classrooms can be more sensitively affected by both indoor activities and ambient concentrations, and mechanical ventilation can be more efficient in reducing PM concentrations than natural ventilation.

The global warming has been recognized as a serious problem. To solve this problem, the country of all the world have conducted techniques such as energy saving and reduction of greenhouse gas. The 30% of total energy is being consumed by buildings domestically and BAS/BEMS are being operated for the management of building energy. But, BEMS is unsatisfactory condition to manage the energy efficiently. In this study, We investigate real application on Chamsaem elementary school as a target buildings and develop 3D Web Browser platform. The spatial information of target buildings is described with used BIM and the energy information is presented for facilities operation and electricity consumption in floor and facility. We perform the quantitative evaluation based on ISO/IEC 9126 and operate this system for two months. in result, energy decreased by about 16%. We expect that the proposed 3D Web Browser system will bring operating efficiency improvement of the current BEMS.

This study developed an algorithm to predict the most efficient evacuation protocol in an elementary school that has an irregular type of architectural planning. The assumption of this study takes a stand point that today's elementary schools are designed in unusual and irregular floor type and, therefore, past architect's knowledge regarding efficient evacuation will no longer effective to save lives. In this regard, this study applied an algorithm that is especially designed to find appropriate locations in general in the field of industrial engineering, which has been proven for many decades. Furthermore, this study not only adapted an engineering model but also conversed to examine spatial relationship and added the concept of group evacuation, which will delay the whole evacuation process, in the tested algorithm to make it more architectural. Consequently, this study compared its outcome with an existing elementary school and questioned its effectiveness in evacuation process based on the algorithm.
