Office Building Energy Efficiency Rating Certification system was enforced in 2010 to enhance spreading high-energy performance and saving buildings. In addition, Government offices require 1st grade of Building Energy Efficiency Rating Certification system. Green Building Act, which is established to reduce the emissivity of carbon dioxide by reducing building energy consumption, will be enforced in 2013, and new apartments and office buildings will be subjected to it. Henceforward, it will extend to other types of buildings and will be phased in. In general, pumps and fans consume approximately half of the air-conditioning energy consumption, and about a quarter of the total building energy consumption when office buildings have total floor area of more than 10000 square meters. This study analyzed the energy demand when applying Variable Air Volume System, and Variable Water Volume System to reduce energy returns of the pumps and the fans by ECO2, which is a computer simulation program used for Building Energy Efficiency Rating Certification system.

Hotel buildings have been changed to the multi-purpose buildings equipped with banquet halls and conference facilities and cafeterias, which is moved away from the previous simple accommodations. When taking a side view of the prevention of fires, the people using hotels have troubles escaping from initial fire. Because they are unspecified individuals and have no information as to the hotels. Also, the part of guest-rooms in charge of accommodations is constructed with the high sound insulation system focusing on privacy of individuals. so, It's hard to incite evacuations in their sleep. Therefore, the standardized floor-plans of guest-room in hotels are classified into 4 types. The four special first class hotels was respectively selected in this research. Zone model fire simulation, CFast was based on the standardized floor. The result from the simulation applied to building EXODUS, the one of the evacuation simulation programs. The indexes for comparison (evacuation speed, exit flow rate, etc.) based on the result of simulation were selected and analyzed. Through the analysis, we knew that the evacuation performance of the parallel type and straight type is superior to the atypical straight type and crossing type. Through such processes, this paper is intended to furnish the fundamental materials when planing hotel buildings which are able to minimize the damages and protect individuals and their properties.

신효정 경북대학교 대학원 2010 국내석사

방재의 관점에서 볼 때 건축물의 고층화는 화재발생에 따른 위험성을 더욱 가중시키고 있음은 물론이고, 재난발생시 대규모 인명 및 재산피해가 발생될 우려가 충분히 있다. 학계 및 전문가 집단에서는 이에 대한 대책마련을 요구하고 있지만, 아직 우리나라의 현행 건축 및 소방기본법 등에서 초고층 건축물의 화재안전을 위한 구체적인 규정이 제정되지 않고 있어 일반적인 건축물에 적용되는 기준을 그대로 적용하고 있다. 이에 대한 보완책으로 우리나라에서는 최근 화재영향평가를 포함하여 초고층 건축물의 특성을 고려한 Performance Based Design(PBD)을 도입하고 있다. 그러나 국내 실정에 적합한 성능위주 피난설계기준 법 및 절차가 개발되지 않은 상황에서 과학적이고 합리적인 성능위주 소방설계가 수행될 수 있을지 우려를 낳고 있다. 본 연구에서는 성능위주의 설계를 실시하고 있는 미국, 일본 등 선진국의 법규와 코드 및 초고층 건축물의 수직성에 기인한 피난설계항목에 대한 사례분석을 바탕으로 법규위주의 피난설계에서 간과할 수 있는 주요 위험요소를 고려한 성능위주 설계방안을 제시하여 국내 초고층 건축물에 대한 안전성 부여 및 성능위주 피난설계에 대한 기초적 자료를 제시하려 한다. In a point of view of the disaster prevention, rising of the buildings have increased the risks according to fires and also have possibilities to cause a large number of human casualties as well as property loss from such disasters. The academics and experts have demanded countermeasures for the issue, however, we are still applying standards for the general buildings to high-rise buildings because current Korean laws such as architecture law and fire services act law didn't establish specific regulations for the fire safety of high-rise buildings. Recently Korean government is now importing Performance Based Design, which considers the characteristics of high-rise buildings including fire consequence analysis, as a complementary measures. Nevertheless, it is concerned whether scientific, logical and performance based fire protection plan could be carried on when appropriate performance based evacuation design standard laws and procedures for domestic conditions are not developed yet. The purpose of this study is to give safety to domestic high-rise buildings and to present fundamental information about performance based evacuation design by indicating performance based plan criteria classified by primary risk items of them that could be overlooked by law centered evacuation plans based on case studies about legislations, codes and evacuation plan items due to the verticality of the high-rise buildings from advanced countries such as the U.S., U.K., and Japan, which are already practicing performance based designs.

Large complex buildings have been constructed to make every work effectively in large cities. The large complex building which features a large number of occupants and complex circulation makes it difficult to complete the emergency egress In some cases in which the fire generates the products of combustion, the smoke causes the reduction of the visibility and this may have a decisive effect on egress time. The smoke flowing through the stair case can't be ignored by the evacuee in the high rise building. Because of this, the smoke control system is required by law. However, the smoke control system can't work properly under the condition of that the fire doors are opened. Therefore, this paper is focusing on the assessment for smoke concentration by analyzing on the egress time when the smoke flows through the stair case. 96 subjects participated in this egress drill and the visibility was limited by the fog machine in order to simulate conditions in case of fire. As a result, the descent speeds in normal and smoke layer decrease by 31% and 55% for each as 0.92㎧ and 0.59㎧. Furthermore, it was found that the evacuation speed decreases as the extinction coefficient increases and the evacuation speed at the minimum extinction coefficient was 0.7㎧.
