( Reeho Kim ) 한국물환경학회 2017 한국물환경학회·대한상하수도학회 공동 춘계학술발표회 Vol.2017 No.-

We are experiencing diversified meteorological disasters including heat wave, tropical night, urban flood and droughts every year. Against this backdrop, Low Impact Development (LID) and Green Infrastructure (GI) are drawing attention as new solutions in order to adapt to climate change and create more pleasant urban environment. Green Standard for Energy and Environmental Design (G-SEED) and prior consultation system for LID are cited as representative governmental institutions with regard to water cycle management. G-SEED plays a leading role in sustainability in the construction sector. The Ministry of Land, Infrastructure and Transport and the Ministry of Environment jointly introduced Eco-friendly Building Certification System for apartment houses in 2002. As the Green Building Development Support Act has put in force in February 2013, it has turned into G-SEED. As the certification standard was revised in September 2016, evaluation items of water cycle management, the fourth specialized sector, are comprised of 4 certification items including stormwater management, utilization of rainwater and effluent groundwater, utilization of water-saving devices and monitoring on the quantity of used water. Since 2014, the prior consultation system for LID has been enforced in accordance with Seoul Metropolitan’s Framework Ordinance on Urban Water Cycle Recovery and Low Impact Development. It aims to induce various development projects to establish a low impact development plan so that deteriorated water cycle management and damage to the water environment could be minimized. The presentation is focused on examining characteristics and effects of the two systems and discuss some present problems. It would be expected to help recover urban water cycle, improve water environment and preserve natural resources by expanding results of systematic implementation and resolving problems.

The Application Evaluation of Autodesk Storm and Sanitary Analysis for the Low Impact Development Design in the Park Area

Reeho Kim,Sangmin Park,Hyundong Lee 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.10

The impermeability layer has decreased the surface storage ability, groundwater level and the time of concentration, and increased the peak flow of storm water runoff and urban floods. Due to the fact that developing the drainage functions in urbanized areas requires a considerable amount of burden in public expenses, which in reality makes it difficult to proceed with, it is necessary to apply the Low Impact Development (LID) concept and transform the drainage-oriented water management to water use and environment- friendly management. As the direction of recent design methods has been shifted to BIM (Building Information Modeling) and GIS (Geographic Information System), it is expected that the LID design will also be shifted to the same direction. Therefore, the related analytical solution is needed, and by using Autodesk® Storm and Sanitary Analysis (SSA) it will enable an interpretation of the city outflow and analysis by making connections with BIM and GIS, and this study’s analysis included making a connection with the runoff model of another city SWMM. This study helped to minimize data loss and rework the process of constructing the network data using the BIM design method and the public GIS followed by the analytical work, and to quickly construct the current network writing by utilizing the public GIS.

한국의 저영향개발과 그린인프라: 현황과 발전 방향

김이호,Kim, Reeho 응용생태공학회 2016 Ecology and resilient infrastructure Vol.3 No.2

도시홍수, 가뭄, 폭염과 열대야 등 다양한 기상재해가 빈번히 발생하고 있어 인명과 재산 피해는 물론 도시의 자연환경보전에 어려움을 겪고 있다. 다양한 기상재해를 최소화 하고 기후변화에 적응하면서 보다 쾌적한 도시환경을 다음 세대에게 넘겨주기 위한 목적으로 저영향개발 또는 그린인프라가 주목 받고 있다. 한국의 저영향개발 및 그린인프라 기술은 현재 보육(incubating) 또는 시연 (demonstrating) 단계에 있다. 중앙정부 및 지방정부의 노력으로 법률 정비가 빠르게 이루어지고 있다. 이를 통해 물을 이용만 하는 회색인프라 (Gray Infrastructure)로 구성된 회색도시 (Gray City)에서 물을 관리하는 그린인프라(Green Infrastructure)로 구성된 녹색도시 (Green City)로 변모하기 시작했다. 보다 체계적인 확산과 보급을 위해서는 한국형 신기술의 개발, 기술의 검증, 기술 기준의 정비, 다분야의 협력과 협업, 교육과 홍보 그리고 시민들의 참여가 요구된다. Diverse types of meteorological disasters that are frequently occurring at the present time, such as urban flooding, draught, heat waves, or tropical nights do not only cause casualties and property damages but also make it difficult to preserve the natural environment of the city. That is why Low Impact Development or Green Infrastructure has recently received lots of attention as a means to minimize meteorological disasters, adapt to climate change and to leave a better urban environment for the next generation. As of now, Korea's low impact development and green infrastructure technology are standing at the stage of incubation or demonstration. Both central and provincial governments have accelerated the updating of laws and regulations, which allows us to turn the Gray City with Gray Infrastructure that only uses water into a Green City with Green Infrastructure that manages the water. To spread and distribute such a notion in a systemic way, it requires new technology development tailored to Korea, verification of technology, and maintenance of related technological standards, cooperation with other industries, training & promotion, and the participation of citizens.

A Study of Information Exchange for Architect & Engineer BIM Design under Low Impact Development Method

Sangmin Park,Reeho Kim 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.11

Collaboration of each division and BIM data continuity have been discussed continuously along with the introduction of the BIM design method in the construction sector and there is an increasing demand for design data analysis and simulation rather than simple design modeling. However, difficulties regarding data exchange using different software from different divisions in BIM design arose early in the implementation stage of BIM. Thus, designs have been conducted based only on the exchange between shape information and partial attributes. As a result of suggesting the data exchange method for design collaboration of BIM design in the civil engineering sector and simulating the analysis process with application of Low Impact Development (LID) in BIM design, smooth collaboration was maintained along with continuity of data between BIM design software and BIM-based analysis was subsequently carried out.

다목적 최적화를 이용한 유역 관리 방안 탐색 : TP 배출부하량 및 강우유출수 저감을 중점으로

박윤경(Park, Yoonkyung),김이호(Kim, Reeho),장종경(Jang, Jong-kyung),송양호(Song, Yangho),양동민(Yang, Dong Min) 한국방재학회 2019 한국방재학회논문집 Vol.19 No.7

최근 도시지역 수자원을 수질뿐만 아니라 물순환 개선까지 고려하는 것으로 유역관리 패러다임이 변화하고 있다. 이러한 패러다임에 맞추어 본 연구는 물순환, 수질 개선할 수 있는 다수의 LID 시설 적용안을 탐색하고자 하였다. 이를 위해 부산광역시 소재 부경대학교 대연캠퍼스에 다수의 투수성 포장이 적용되는 경우로 연구를 수행하였다. 그 결과, 총 35개의 투수성 포장 적용안이 탐색되었다. 탐색된 적용안을 살펴보면, 하나의 목적(예를 들어 수질개선)만을 고려하여 투수성 포장을 설치할 경우 다른 목적(예를 들어 강우유출수 감소)의 대한 효과가 미미하거나 예산이 과도하게 사용될 수 있는 여지가 있음을 확인하였다. 따라서, 본 연구에서 제시하는 방법을 이용한다면 한정된 예산에서 두 가지 목적(수질개선 및 강우유출수 감소)을 모두 달성할 수 있는 투수성 포장 설치안 제시가 가능할 것으로 판단된다. Recently, in urban areas, watershed management paradigms have changed the water cycle and water quality. This study explored the implementation of multiple low impact development (LID) facilities to improve the water cycle and water quality according to the paradigms. The study area was the Daeyeon campus of Pukyong National University, Busan. In this area, permeable pavement is installed in various LID facilities. In this study, a total of 35 optimal implementation plans of permeable pavement are presented. The suggested optimal designs confirm that the installation of a permeable pavement considering one purpose alone (for example, water quality improvement) does not satisfy the other purposes (for example, runoff reduction); in other words, such an installation is uneconomical. Therefore, this study proposes optimal installation designs for permeable pavements that can achieve multiple purposes (in this case, water quality improvement and runoff reduction) with a limited budget using the methodology suggested herein.
