Since 1980, rapid social and economic development due to increased plant construction has led to a plant dormitory in a short period. In recent years, by the advent of the durability of dormitory remodeling is a critical need. However, user requirements due to the lack of owner's budget do not reflected. As a result, users have complained about the scope of construction, and construction stakeholder in accordance with the budget efficiency of the complaints have decreased. In this study the remodeling requirements in the planning stages is proposed for the remodeling process. In addition work type and element can select a range of construction worksheet are proposal.

승선생활관은 거주밀도가 높으며 유동인구도 특정한 시간에 몰리는 특징을 가지기 때문에 화재와 같은 재난이 발생할 경우 큰 인명피해 발생으로 이어질 수 있다. 이에 이 연구에서는 국내 K대학의 신축 승선생활관을 대상으로 화재 시뮬레이션 프로그램인 FDS를 사용하여 화재발생 시의 위험성을 예측하고 이에 따른 문제점을 분석하여 개선방안을 제시하였다. 연구결과를 정리하면 다음과 같다. 승선생활관 다림질실에서 화재발생 시, 발화 후 65초에 연기감지기가 작동하고, 13초 뒤인 78초에 스프링클러가 작동하기 시작한다. 온도 및 일산화탄소 농도는 각각 241초, 248초에 허용기준 값에 도달하지만, 발화 후 66초에 허용 가시거리 값에 도달하기 때문에, 화재발생 후 적어도 1분 이내에 준비를 끝내고 피난을 개시해야 인명피해가 발생하지 않을 것으로 예측된다. 이 기숙사의 화재위험성 예측 결과를 종합해 보았을 때, 인명안전에 가장 위험한 요소를 가시거리 값으로 판단할 수 있다. 가시거리 확보를 위해 제연설비를 설치할 경우, 제연설비 설치 후 승선생활관 복도의 연기확산이 개선되는 것을 확인할 수 있었다.

Recent years in Korea, some new developed buildings are only using electricity as power for heating, cooling, bathing and even cooking which means except electricity, there is no natural gas or other kinds of energy used in such kind of building. In vehicle industry area, scientists already invented electric vehicle as an environment friendly vehicle; after that, in architecture design and construction field, buildings only using electricity appeared; the curiosity of the environment impact of energy consumption by such kind of building lead me to do this research. In general, electricity is known as a clean energy resource reasoned by it is noncombustible energy resource; however, although there is no environmental pollution by using electricity, electricity generation procedure in power plant may cause huge amount of environment pollution; especially, electricity generation from combusting coal in power plant could emit enormous air pollutants to the air. In this research, the yearly amount of air pollution by energy using under traditional way in research target building that is using natural gas for heating, bathing and cooking and electricity for lighting, equipment and cooling is compared with yearly amount of air pollution by only using electricity as power in the building; result shows that building that only uses electricity emits much more air pollutants than uses electricity and natural gas together in the building. According to the amount of air pollutants comparison result between two different energy application types in the building, residential SOFC (Solid oxide fuel cell) is simulated to apply in this building for decreasing environment pollution of the building; furthermore, high load factor could lead high efficiency of SOFC, in the scenario of simulating applying SOFC in the building, SOFC is shared by two or three households in spring and autumn to increase efficiency of the SOFC. In sum, this research is trying to demonstrate electricity is a conditioned environment friendly energy resource; in the meanwhile, SOFC is simulated efficiently applying in the building only using electricity as power to decrease the large amount of air pollutants by energy using in the building. Energy consumption of the building is analyzed by calibrated commercial software Design Builder; the calibrated mathematical model of SOFC is referred from other researcher's study.
