  • The experiment was conducted to investigate the potential for environmentally friendly cultivation of cv. Haryeong, which was bred by the National Institute of Highland Agriculture in 2006, through evaluation of the late blight field resistance at the farmer's practices level. cv. Haryeong showed higher field resistance to late blight as 590.3 in mean Area Under the Disease Progress Curve (AUDPC) during the cultivation period than cv. Superior as 1377.7 in AUDPC. However there was no observed different trend among the experimental treatments. Mean of tuber yield of cvs. Haryeong and Superior were 2,870 kg/10a and 2,301 kg/10a, respectively, and in all experimental treatments Haryeong was 25% higher than those of Superior. Mean of dry matter content of Haryeong and Superior were 18.1% and 16.1%, respectively, and there were no significant differences among the experimental treatments. cv. Haryeong was confirmed as a suitable cultivar for environmentally friendly cultivation in this experiment. In the future, additional research on fertilization and disease management will be required.

  • A various building certification systems are being enforced in Korea. However, the enforcement of many building certification systems has brought on the concerned people's confusion and the operation of various building certification systems which have similar assesment items causes much time and economical losses. Therefore, in this paper, the features of the GBCS(Green Building Certification System), Housing Performance Indication System, Building Energy Rating System, and Green Home Standard and Performance Evaluation System are compared and the correlations among each building certification system are analysed. As a result, it is presented that a considerable number of assessment items were so similar and identical that integration of building certification systems is needed for effective operation of these systems.

  • 최근 친환경 자재를 사용한 건축물이 증가하면서 전통 가옥 뿐만 아니라 다양한 형태의 목조 건축물들이 많이 지어지고 있다. 목재는 건축자재로서 우수한 장점이 많은 반면 화재에 취약한 치명적인 단점을 갖고 있다. 본 연구는 목재건축물의 화재특성을 분석하기 위하여 목재건축물의 화재해석 모델링을 구성하고 수치해석하였으며, 화재시 화염전파의 패턴을 분석하였다. 발화는 내부발화와 외부 화염전이로 구분하였으며 내부발화는 다시 건물 중앙 발화와 벽면발화로 구분하여 수치해석을 수행하였다.

  • This study is expected to provide some basic data on how to apply more economical and efficient eco-friendly factors to reduce the carbon emissions. It has been scrutinized and analyzed the environmental factors of passive eco-friendly elements along with active eco-friendly elements as more efficient factors for energy conservation based on the case of a newly constructed broadcasting building with the green building certification in Sangam-dong DMC area. The first analysis was the energy consumption trends in Korea and the necessity of energy saving. Secondly, it was examined the energy consumption in the current status of the broadcasting building. Thirdly, it was looked into the correlation between the eco-friendly design application factors applied to the broadcasting building and the energy consumption types. As a result of the analysis, the application of fan and feed pump inverter along with ventilation system of waste heat recovery ventilation system were more meaningful in accordance with the economic feasibility of broadcasting buildings rather than economical effect of passive elements such as rooftop garden, reinforcement of building insulation. Also, the application of lighting control had the economical feasibility. Therefore, when it is intended to change the green building certification energy related evaluation items of the similar broadcasting building types, it is necessary to change the direction of adding weight to the more economical active element items in the future.

  • Anomaly detection on building energy consumption has been regarded as an effective tool to reduce energy saving on building operation and maintenance. However, it requires energy model and FDD expert for quantitative model approach or large amount of training data for qualitative/history data approach. Both method needs additional time and labors. This study propose a machine learning and data science approach to define faulty conditions on hourly building energy consumption with reducing data amount and input requirement. It suggests an application of Support Vector Data Description (SVDD) method on training normal condition of hourly building energy consumption incorporated with hourly outdoor air temperature and time integer in a week, 168 data points and identifying hourly abnormal condition in the next day. The result shows the developed model has a better performance when the ${\nu}$ (probability of error in the training set) is 0.05 and ${\gamma}$ (radius of hyper plane) 0.2. The model accuracy to identify anomaly operation ranges from 70% (10% increase anomaly) to 95% (20% decrease anomaly) for daily total (24 hours) and from 80% (10% decrease anomaly) to 10%(15% increase anomaly) for occupied hours, respectively.

  • Submetering electricity consumption data enables more detail input of end use components, such as lighting, plug, HVAC, and occupancy in building energy modeling. However, such an modeling efforts and results are rarely tried and published in terms of the estimation accuracy of electricity demand. In this research, actual submetering data obtained from a university building is analyzed and provided for building energy modeling practice. As alternative modeling cases, conventional modeling method (Case-1), using reference schedule per building usage, and main metering data based modeling method (Case-2) are established. Detail efforts are added to derive prototypical schedules from the metered data by introducing variability index. The simulation results revealed that Case-1 showed the largest error as we can expect. And Case-2 showed comparative error relative to Case-3 in terms of total electricity estimation. But Case-2 showed about two times larger error in CV (RMSE) in lighting energy demand due to lack of End Use consumption information.

  • 하천의 제방은 하천수의 범람을 방지하기 위하여 인공적으로 만든 구조물로서, 유수의 흐름을 일정하게 하고 자연재해에 대하여 제내지를 보고하기 위한 목적도 있다. 제방은 제내지와 제외지의 수위차로 인해 발생하는 파이핑, 제방의 월류, 사면의 탈락 등으로 파괴가 발생되고, 제방의 파괴는 제내지의 인명, 토지, 건물 등에 많은 피해가 발생한다. 이러한 제방의 파괴를 방지하기 위하여 제방 사면의 호안, 차수벽, 수제 등을 설치하고 있으며, 구조물 외에도 제방 응급복구를 위한 모래주머니, 비탈면 보호 시설 등을 이용한 피해방지에 대한 대책을 세우고 있다. 제방 구조물의 대부분은 콘크리트를 이용한 고강도 재료를 사용하여 설치되고 있으며, 재료의 환경성에 대한 문제점이 대두되어 왔다. 이에 따라 코코넛껍질을 이용한 사면 보호공, 고강도 식생매트를 이용한 사면 보호 등 친환경 재료를 이용한 사면보호 공법에 대한 연구들이 다양하게 진행되어 왔다. 본 연구에서는 미생물을 이용하여 사면을 보호하기 위한 블록 및 피복기법에 대한 연구를 진행하고 있으며, 다양한 환경성 및 무독성 검증도 병행중에 있다. 그 중 본 연구에서는 신소재와 황토, 모래, 석고를 다양한 비율로 조합하여 블록으로 활용하기 위한 일축압축 강도 실험을 수행하였으며, 신소재의 소류력 저항능력을 실험하기 위하여 안동 하천실증연구센터의 급경사 수로에 신소재를 피복한 시험구를 조성하고 5m/s 이상의 유속에서 저항능력 실험을 수행하였다. 본 연구에서는 본 실험 결과를 기반으로 하여 추후 다양한 친환경 재료를 이용한 조합을 통해 기존 콘크리트 블록에 준하는 강도를 발현할 수 있는 신소재 블록의 개발을 목표로 하고 있다.

  • This Study, as a Eco-Friendly Design Process of Office for sustainable design, aims to develop a sustainable design process by letting the designers easily approach the concept of Eco-Friendly Design Process and applying this to Eco-Friendly Design Process when the designers perform design. Through a review on simulation, a research was made on the seriousness of environmental problems and control that was caused by design, Environmentally friendly design, sustainability, and sustainable design's background and definition were studied. In order to develop a Eco-Friendly Design Process, an existing review from Building Energy Simulation that proposed about energy environmentally friendly design element and sustainable design element's semantic similarities were restructured as sustainable design element comparative analysis. Restructured sustainable design elements and the relationship between sustainable design elements and the relationship of each product developmental process levels were analyzed. Finally, through clustering, sustainable design guideline were developed. This Eco-Friendly Design Process is expected to be applied to as one of the methods in solving the global environmental issues in design practice.
