  • The Urban-type building is an building that it relaxed the construction standard and subsidiary facility standard. The most of the urban-type buildings are pilotis, the main case of representing these building's fire risk is the Uijeongbu fire this study investigated to piloti urban type housing risk on the basis of Uijeongbu fire, and we checked structural problem that unable to escape from the rooftop inside the piloti. also, there was confirmed limit to the evacuation of the occupants because the smoke was rapidly transferred to the top layer through inside the electric duct. and when we analyzed smoke flow use of Fire simulation, it was confirmed Available Safety Egress Time that is four minutes of CO.

  • The fire that broke out in a residential and commercial complex in Ulsan in October 2020 was large, but no deaths occurred. For this reason, there was a difference from the previous cases, so it was analyzed through field survey. The fire was expanded to the entire building by aluminum composite panels constructed by external heat method and SMC panels in evacuation safety zones, and fire was expanded to nearby mart due to wind on the day of the fire, and there were many evacuation spaces such as 15th, 28th, and rooftop heliports.

  • 본 연구는 급속하게 성장하는 시설농업과 동시에 증가하는 에너지 사용량 및 탄소배출량을 저감하기 위해, 온실의 에너지 부하를 동적으로 분석하기 위한 작물에너지의 다중 회귀모델 개발을 수행하였다. 온실은 연중 안정적인 대량 생산을 위한 적절한 환경을 조성하기 위해 에너지 투입이 필요하다. 도시농업의 일종인 옥상온실 플랫폼을 통해 건물에서 버려지거나 활용되지 않는 에너지를 옥상온실에서 사용할 수 있다. 옥상온실의 효율적인 운영을 위해서는 다양한 환경 조건에 대한 동적 에너지 분석이 선행되어야 하며, 온실에 도입되는 태양 에너지의 40-75%가 작물을 위한 에너지 교환이므로 필수적으로 고려되어야 한다. 한국기계연구원 내 옥상온실에서 여름철에 청경채를 재배하며 생장단계에 따른 에너지 교환을 분석하였다. 작물을 중심으로 미기상 및 양액 환경 분석과 생장 특성 조사를 수행하였다. 정식일수에 따른 엽면적지수를 추정하였으며, 개발된 수식은 결정계수 0.99로 분석되었다. 또한 작물에너지 흐름에 지배적인 잎 표면온도로부터의 현열부하와 증발산에 의한 잠열부하로 나누어 모델을 개발하였다. 엽온과 증발산량을 각각 다중 회귀모델을 이용하여 추정하고 실측한 값을 비교해 보았을 때, 평균 결정계수 0.95, 0.71로 분석되었으며, 이 모델을 이용하여 옥상온실의 에너지 부하를 동적으로 산정하기 위한 모델에 입력값으로 사용할 수 있을 것으로 판단된다.

  • Background and objective: Vertical smart farm (VSF) is an alternative that contributes to solving various problems such as climate change and food shortage. This study focused on the types and awareness of VSF to introduce and diffuse VSF. We aimed to investigate the types of VSF and citizens' awareness on VSF. We analyzed 1) where the smart farm technology could be implemented on a building; 2) what citizens think about VSF; and 3) suggested what is most necessary for the introduction and diffusion of VSF in the future based on citizens' perception. Methods: VSF types were investigated through case studies on VSF in Korea and overseas. Citizens' perception on VSF was investigated through a questionnaire survey. A statistical analysis was conducted with the survey results for implications of the introduction and diffusion of VSF. Results: Four types of VSF were derived: rooftop farms, facade farms, indoor farms, and farms using the whole building. The survey showed that 29.2%, 27.8%, and 22.2% of respondents knew well about urban agriculture, smart farms, and vertical smart farms, respectively. Respondents answered that improving awareness is the most important factor to introduce VSF. According to the statistical analysis, it was determined that education and promotion of the necessity of VSF would be important to diffuse the VSF. Conclusion: VSF can be a solution to a variety of problems we face. The results of this study suggest a direction for the introduction and diffusion of VSF. In order to introduce VSF in the future, additional studies must be conducted on the legal system.

  • Building-integrated photovoltaic(BIPV) systems can operate as a multi-functional building components, which generates electricity and serves as part of building envelope. It can be regarded as a new architectural elements, adding to the building's aesthetics. Besides of these benefits, the application of PV systems into school buildings tends to play an important role in energy education to students. In this context, this study aims to analyse the applicability of PV systems into school buildings. For an existing school building, four types of BIPV designs were developed; rooftops, wall-attached, wall-mounted with angle, and sunshading device. Based on energy modeling of those BIPV systems, the whole 60.1kWp rated PV installation is expected to yield about 65.6MWh of electricity, that is about 50% more than the annual electricity consumption of the school, 44MWh. It was also found that the applicability of the PV systems into the school building was very high, and the rooftop systems with the optimized angle was the most efficient in energy production, followed by sunshading, wall-mounted with angle and wall-attached. It concludes that school buildings have a reasonable potential to apply PV systems in the aspects of building elements and electricity production.

  • Latex-modified concrete using ready mix concrete (R-LMC) was developed for application of building construction project (specifically, the rooftop of a parking garage unable to use heavy equipments for bridge deck overlay) due to three major outstanding properties of R-LMC; bond strength, resistance of cracks at early age, and resistance of freezing and thawing. However, R-LMC at the placement stage is required to be sufficiently cured because R-LMC is very sensitive to rate of evaporation of surface moisture. This study focused on effects of different curing methods and climate condition on cracks on the surface of hardened R-LMC considering the chart of rate of evaporation of surface moisture from concrete provided by American Concrete Institute in manual for placement of latex modified concrete.
