최근 지속 가능한 도시시스템 구축을 위해 신, 재생에너지 시스템에 대한 사회적 관심이 집중되고 있으며, 이에 따른 관련 연구가 활발히 진행되고 있다. 전체 에너지 소비의 40% 이상을 차지하고 있는 건설부문 또한 이러한 경향이 두드러지고 있다. 조경부문도 재생에너지설비가 적용된 다양한 조경시설물이 제작, 설치되고 있으나, 계획, 설계단계에서 활용 가능한 체계적인 연구가 아직 국내에 보고되고 있지 않다. 본 연구는 조경시설물에 재생에너지 시스템을 적용하면서 발생되는 에너지, 경제적 효과를 정량적으로 도출하여 조경계획 및 설계에 활용하고자 한다. 이를 위해 서울, 인천, 대구의 도시공원 내 가로등 전력을 계통연계형 태양광시스템으로 대체하는 스마트 가로등 적용 시나리오를 적용하여 에너지, 경제적 해석을 수행하였다. 전산모의는 NASA Satellite Meteorological Data를 이용한 청정에너지 전산모의 프로그램인 RETScreen$^{(R)}$을 적용하였다. 결과적으로 해당 도시의 기후적 특성에 따라 발전량 및 경제성의 차이를 보였으며, 본 연구결과는 향후 조경계획 및 설계에 건전한 재생에너지 시스템 적용을 위한 의사결정에 활용될 것으로 사료된다. Recently, as the social interest increase has been focused on new renewable energy system to build-up sustainable urban planning system, the related studies have been actively conducting. As well as in other areas, the construction area, which accounts for over 40% of the total energy consumption, clearly showed this tendency. Whereas, various landscape facilities applying renewable energy equipments have been manufactured and installed, systematic study available for planning and designing is rarely found in Korea. This study is expected to contribute to the landscape planning and designing by quantifying the energy-efficient and economic advantages of the renewable energy system for landscape facilities. For this purpose, the analysis on the energy-efficiency and economic values under the scenario that the current fossil power supply for the streetlights in urban parks in Seoul, Daegu, and Incheon were replaced by photovoltaic power generation were performed through RETScreen$^{(R)}$ a clean energy simulation program based on the NASA Satellite Meteorological Data. As a result, the generated power and the economic values vary depending on the climatic features of the appointed cities. This study will be used to build up the effective decision-making in applying the clean renewable system to the plan and design of landscaping.

One of the challenges in planning fire-safety structures is predicting fire temperature. This takes top priority to fire safety engineers since it helps figure out moments that put human lives at risk, identify flashover and when a structure will collapse. Fire engineers around the world have conducted numerous tests to predict fire temperature. Formula for predicting fire before and after flashover is one of the test outputs. Pre-flashover helps identify time allowed for evacuation, which protects human lives, and post-flashover helps identify time in which structures are at risk of collapse i.e. structural stability. This research studied fire temperature predicting formula by limiting compartment fire at its peak from the 1950s and post-flashover. It conducted literature research on characteristics of compartment fires.

Fire was and remains a great threat to historic buildings of wood. This threat is omnipresent and often results to irreparable property losses especially cultural heritages. Fire of historic buildings continues to increase every year. The purpose of this study is to preserve a life safety, historical heritage and architectural & cultural values by pursuing for fire safety in the historical buildings. This study shall employ two research methods: a literature review and field survey methods. The literature review shall focus on the observations of characteristics noted in fire codes. The field survey shall cover a heat analysis and fire protection equipment. A method is proposed to investigate fire codes related historical building, reported fire history Fire Codes and Regulations for modern buildings are not always applicable on the historic buildings. Old buildings, and some new buildings with architectural, historical or cultural importance may have values which cannot be measured on a monetary scale. Their protection against the damage caused by fire is considered to be one of the basic moral duties of society. It is strongly recommended, therefore, legislation for fire safety in historical buildings must be extended to a complementary relationship with 'active' fire protection measures, to provide safety in real historical building in real fire situations. The development and application of performance based Codes and the Fire Safety Engineering approach seems to be a rather reasonable and effective way to deal with this historical buildings.

It is told that disaster is learnt from disaster. In this aspect, the first approach to disaster today is to analyze the patterns and sizes of fire by building up the database for disasters occurred in the past. In order to preserve our cultural property buildings from fire, this study built up the fire chronological table of the Choson Dynasty period based on the annals of the Choson Dynasty and analyzed its fire cases like below. (1) According to the annals of the Choson Dynasty, the total number of fire in the Choson Dynasty period was 375 cases while there was a periodic relation between fire occurrence number and periodic dynasty. In other words, the fire occurrence frequency was shown to be high when the domestic situation was chaotic like Japanese Invasion of Korea in 1592 or the Manchu war of 1636. (2) The season with high fire occurrence frequency was spring. Those fires might be caused by accidents or negligence in the period of beginning farm work, which was different from the current electronic fire that occurs frequently usually in winter time. (3) The fire occurrence frequency for different places was private house(174 cases, 46%), government office(94 cases, 25%), palace(62 cases, 17%), royal tomb(32 cases, 9%) and natural fire(13 cases, 3%) in order. (4) As there were 32 cases which was recorded with the number of the dead, the fire which killed more than 25 people was two cases. It was shown that 55 cases of fire were less than 100 burnt houses while the number of massive fire which burnt more than 500 households was 12 cases.
