대구지하철화재 소방 활동 조사 분석을 통한 지하 공간 대형화재 시 소방 활동 개선방안에 관한 연구
홍원화,김동식,전규엽 대한건축학회 2004 대한건축학회논문집 Vol.20 No.11
Underground spaces are actively being developed. Especially, the trend of this development is horizontally to connect other buildings by underground floors, that is, to make underground passages among buildings, it seems to be a great network space. Many inexperienced pedestrian are not aware of these passages and are anticipated to be exposed to a great of danger when there is a fire. It happened that the fire at Joong-Ang Ro station of Daegu. It might be ended as fire happening. However, it proceeded to the disaster giving a number of damage because of the incomplete system of disaster prevention. Now we will need the new fire fighting activity's system at the conflagration of underground space. This study is to research the fire fighting activity and to analyze the fire fighting system at the Daegu subway fire. And This data will use in base of fire fighting activity at the conflagration of underground space.

각종 건축물의 비상시건축설비기능의 중요도 조사분석 : 일본 동경을 중심으로 Focused on Tokyo , JAPAN
홍원화 대한건축학회 1999 대한건축학회논문집 Vol.15 No.9
The main purpose of this research is the analysis of the maintenance-function of the building facilities prevention disaster center and the principal buildings acted as a city during the interruption of the life-line. The conclusion of this research: (1) The analysis of the importance of the buildings facilities shows that the most important facilities are the electrical, and then facilities for communication and water supply. (2) Concerning the condition of electric power and water supply, in case of suspension of the electric power and water supply respectively, there are many buildings with independent electric power supply, but few buildings with independent water supply.

대형 건축물의 태양광 발전시설 도입에 따른 경제성 및 환경성 효과분석 : 대구 컨벤션 센터(EXCO)를 중심으로
홍원화,장민호,전규엽 대한건축학회 2004 대한건축학회논문집 Vol.20 No.9
The purpose of a paper is to know the first invest cost, a payback period, and an environmental result on EXCO when we apply a photovoltaic system to it Today, the need for alternative energy has increased due to the global environmental problems and energy depletion Buildings built nowadays have a tendency of getting innovative facilities and play important roles themselves as education and ads After Daegu City has tried to be selected as a Solar City, it makes alternative energy necessary for many public buildings Following this trend, Daegu City has a plan of putting a photovoltaic system on large buildings For instance, EXCO, exhibition and convention building in Daegu, is on the process of having a photovoltaic system. When assuming this project, the first thing we should have is an amount of hourly energy consumption for EXCO The hourly data for the electric energy were gathered by field survey for EXCO. Then, three places on EXCO were regarded of a photovoltaic system Every energy on each place was calculated respectively Considering the first invest cost, the payback period needs about 15 years in an environmental evaluation, the deduction of carbon 야oxide was also obtained with a certain chemistry equation. Evaluating the first invest cost, a payback period, and an environmental result, this paper Will give some information of choosing where to place the photovoltaic system on EXCO

대구시 D은행 본사 빌딩의 열원설비 개보수 유형에 따른 경제성 분석
홍원화,정연욱 대한건축학회 2004 대한건축학회논문집 Vol.20 No.7
The old equipments of heat sources can be a factor of increase in the cost of fuel and electric power, and a loss of energy. Exceeding time limit allowing building equipments to be sustainable has lead to the decline of building's performance. Their reasons considerably require of amelioration at building's performance. Therefore, in this study, a process of maintaining and repairing old equipments in office building, we surveyed the plans of diagnosis on the main equipments and the measures against malfunction, and suggested some solutions when considered, repairing the equipments of heat sources. and compare initial investment and annual operational costs according to classification of heat sources, we will provide evaluation data for selecting the most efficient and economic system.
