This study aims to suggest design data for planning university dormitories to meet the needs of the occupants' through field survey and questionnaire survey at the sampled dormitories in A University in 2006. and the purpose of this study is to suggest program of the suitable common space in the dormitory buildings on campus, especially referred to newly built dormitory of A university. In conclusion, Living space accounts for 56.17%, studying space accounts for 1.86%, well-being support space accounts for 2.49%, convenience support space accounts for 8.35%, management space accounts for 3.08% of the whole area in the program of newly built dormitory.

The purposes of this study were to determine the actual state of the indoor air quality by TVOC concentration and residents' responses and to analyze the influencing factors of IAQ in newly built university dormitory. The field measurements on the levels of TVOC and HCHO were carried out three times at an interval of 4 weeks in 3 rooms of a dormitory. The questionnaire survey on the residents that inquired into the lifestyle, the consciousness related to IAQ, and the responses of SHS was fulfilled. According to the results, the level of TVOC was approximately $0.14{\sim}18.5ppm$ and HCHO was $0.23{\sim}6.89ppm$ during 3 month since construction completion, which are seriously in excess of standard level, and seemed to be on the decrease as time goes by. The factors influencing the differences of the levels of TVOC or HCHO were the amount of ventilation including infiltration, heating temperature, relative humidity, or the use of living things including chemical. However, the residents rarely felt the responses of SHS and did not be conscious of the importance of ventilation.

The purposes of this study were to determine the actual state of the indoor air quality by measuring TVOC Concentration and surveying residents' responses in a newly built university dormitory and to analyze the influencing factors of IAQ. Field measurements on the concentrations of TVOC and HCHO were carried out three times at 4 week intervals in 3 rooms of a dormitory. A questionnaire survey was conducted on residents which inquired into the resident's lifestyle, their consciousness of IAQ, and the responses to SHS. According to the results, TVOC concentrations were 0.14~18.5 ppm and HCHO concentrations were 0.23~6.89 ppm during the 3 months following the completion of construction, showing a serious state in which standard levels are exceeded, though these levels seemed to decrease over time. The factors influencing the differences in the levels of TVOC and HCHO were the ventilation volume including infiltration, the heating temperature, relative humidity, or the use of living matter that include chemical ingredients. However, the residents rarely felt the symptoms of SHS and were not conscious of the importance of ventilation.

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.
