이병연(Lee Byung-Yun),김광현(Kim Kwang-Hyun) 대한건축학회 2009 대한건축학회논문집 Vol.25 No.4

This paper analyses the structure of integrated design of sustainable architecture and proposes improvement of it. Existing Integrated design process(IDP) have some pitfalls of rigid process and fragmentation of each elements. The cognition of ecological system composed of built and fluid environments and inter-relationship between them (environmental indexes) sheds lights on improvements of integrated design. Projects get a wide-range of targets from it and the structural frame of them can be established in detail in order to decide the level and methodology of integration. Taking the whole structure in mind, the process of integration design can be settled. 1) During planning step, overall strategy is developed with the guidance of environmental indexes and design team is set up. 2) During schematic design , integration level and alternatives are developed through design workshops with many verification tools(a feedback design). 3) During design development, the performance of integration systems are optimized with material selection, occupants pattern and seasonal operation schedule. Several design tools have been developed, but their specific target cannot cover a whole integrated design process, so the optimized integration of tools should be investigated as well.

지역별 단독주택 에너지 절감 리모델링 전략 민감도 분석

이병연(Byungyun Lee),CHEN HAICHAO 한국산학기술학회 2020 한국산학기술학회논문지 Vol.21 No.9

그린 리모델링 전략 수립이 기술 중심적으로 진행되어 현장 상황을 반영한 맞춤형 전략 수립의 필요성이 제기된다. 본 논문은 리모델링 활성화를 위하여 현장에 적합한 리모델링 전략수립 방법론으로 민감도 분석을 통한 기술전략평가와 활용가능성 분석을 목적으로 한다. 30평형 규모 단독주택을 대상으로 에너지플러스엔진과 모드프론티어 최적화기법을 통합하여 활용하여 서울, 대전, 부산지역에 1980년대 이전, 1984년, 2010년 준공기준을 적용한 총 9개 모델대상 최적화 후 민감도 분석을 통한 리모델링 전략 우선순위를 도출하였다. 1980년 이전 모델의 경우 지붕 단열성능강화 전략이 민감도 상위 순위를 갖는 것으로 나타났다. 창호 총일사취득율 기준은 전 지역, 전 준공 시기를 막론하고 다음 상위 민감도를 갖으며, 이는 열관류율 중심 기준에서 총일사취득율 기준을 포함하는 성능 기준으로 확대될 필요가 있음을 보여준다. 대규모 철거공사를 수반하는 창면적비의 조정은 민감도가 낮아 형상 유지 리모델링의 효용을 확인하였다. 사례별 상이한 민감도 결과는 리모델링 전략 수립에서 민감도 분석을 경제성, 시공성 등의 기준 등과 함께 종합적인 리모델링 전략 수립의 가능성을 제시한다. The establishment of a green remodeling strategy is focused on technology, so the necessity of establishing a customized strategy considering the field situation has emerged. This paper examined the technology strategy through sensitivity analysis as a methodology for guiding strategy. For a 90-square-meter detached house, nine models of the construction standards of pre-1980s, 1984, and 2010 in Seoul, Daejeon, and Busan were assessed using the optimization method that combines the energy plus engine and the ModeFrontier. Sensitivity analysis was performed, and the remodeling strategy priority was derived. For pre-1980 models, the strategy for enhancing the roof insulation performance had a significant priority. The SHGC values of the windows were found to have the next highest priority regardless of the region and the time of completion, showing that the performance standard, including the SHGC, needs to be expanded. The possibility of remodeling while maintaining the existing geometry was confirmed because the adjustment of the window wall ratio accompanying large-scale demolition works has low priority. The priorities of technology strategies in each case showed very different patterns, suggesting the possibility of establishing a remodeling strategy by a comprehensive evaluation along with economics and constructability analysis.

클러스터링 분기를 이용한 다중 서열 정렬 알고리즘

이병일(Byung-Il Lee),이종연(Jong-Yun Lee),정순기(Soon-Key ung) 한국컴퓨터정보학회 2005 韓國컴퓨터情報學會論文誌 Vol.10 No.5

다중 서열 정렬(multiple sequence alignment, MSA)은 단백질과 핵산 서열들의 분석에 필요한 가장 중요한 도구이다. 생물학적인 서열들은 그들 사이의 유사성과 차이점을 보여주기 위하여 각각의 서열들을 수직적으로 정렬한다. 본 논문에서는 클러스터링 분기를 이용하여 두 그룹의 서열들 사이에서 정렬을 수행하는 효율적인 그룹 정렬 방법을 제안하였다. 제안한 알고리즘(Multiple Sequence Alignment using Clustering Divergence : CDMS)은 하향식 발견 방법인 트리 형태의 병합을 위해 클러스터링 방법으로 구축하였다. 클러스터링 방법은 가장 긴 거리를 가지는 서열을 두 개의 클러스터로 나눌 수 있다는 것에 기초하였다. 제안한 새로운 서열 정렬 알고리즘은 기존의 Clustal W 알고리즘 보다 질적 향상과 처리 시간 단축 O(n³L²) 이 기대된다. Multiple sequence alignment(MSA) is a fundamental technique of DNA and protein sequence analysis. Biological sequences are aligned vertically in order to show the similarities and differences among them. In this paper, we propose an efficient group alignment method, which is based on clustering divergency, to perform the alignment between two groups of sequences. The proposed algorithm is a clustering divergence(CDMS)-based multiple sequence alignment and a top-down approach. The algorithm builds the tree topology for merging. It is also based on the concept that two sequences having the longest distance should be spilt into two clusters. We expect that our sequence alignment algorithm improves its quality and speeds up better than traditional algorithm Clustal-W.

자연채광 및 에너지 복합성능 최적화 프로세스를 통한 체육관 천창 통합설계

이병연(Lee, Byungyun),박서우(Park, Seowoo) 대한건축학회 2022 대한건축학회논문집 Vol.38 No.10

This study aimed to analyze multi-purpose optimized design alternatives for sports halls to minimize total energy consumption, maximize daylight quantity, minimize glare probability and develop meta-models to predict energy and daylight performance during the early design stage. The automatic optimization tool of Modefrontier integrated with the rhino-grasshopper model was developed and simulated with the energy plus and radiance engine. Three optimization phases were conducted, and the variable ranges and optimization algorithms were selected for each phases aim. In the first and second phases, the optimized cases were selected in the Pareto surfaces and compared to analyze the influence of glare prevention on the best-performing cases. Lastly, the meta-model was developed and presented to predict energy and daylight performance with a variation of the three most sensitive variables to predict the performance without energy simulation by architects and all participants. The rooftop daylighting model with cone-type lightwell was selected for the analysis with four geometric variables and two material variables for parametric design development. The results revealed that the window-floor-ratio was a dominant variable for all energy, useful daylight index, and daylight glare probability followed by tilting height and lightwell height. The window-floor ratio in the Pareto-optimized cases ranged between 11 and 21 percent in the first optimization without the glare-free objective; the range was reduced to between 8.5 and 14 percent. The range of lightwell height shrunk between 360 and 480 mm to between 240 and 360 in relieving glare. The developed response surface model with restricted window-floor ratio of 9.5-13 percent is expected to provide relevant information for future decision-making purposes.

이병연(Byungyun Lee) 한국산학기술학회 2016 한국산학기술학회논문지 Vol.17 No.6

본 논문은 저에너지 건축물 보급을 활성화하기 위하여 시행되고 있는 국내외 인센티브 제도를 비교분석하고 이를 통하여 국내 저에너지 건축물 인센티브 제도의 개선을 모색하기 위한 목적으로 한국, 캐나다, 미국, 싱가폴의 국가단위, 지방정 부단위 제도를 분석 대상으로 하였다. 인센티브 제도의 체계는 1) 인센티브 종류 및 수혜자의 규정, 2)성능기준 및 평가방식의 정립, 3) 통합설계지원, 4) 재원의 확보를 근간으로 구성된다. 한국을 제외한 모든 국가들이 통합설계에 참여하는 전문가에 대한 인센티브 제도를 도입하고 있으며, 신축 중심 인센티브가 리모델링 건축물을 포함하는 방향으로 전환되고 있다. 인센티 브 제도의 근간인 성능기준은 각 프로그램이 속한 국가 또는 지방정부가 규정하는 통합에너지성능분석기준에 따라 통합성능 에 따른 지원이 주를 이루고 있으며, 개별 기술에 대한 지원을 보완하여 지원 범위 확대 경향을 보이고 있다. 통합 성능의 경우에도 초기 시뮬레이션에 의한 검증에서 실제 에너지사용량에 의한 검증으로 전환되어 시공품질 및 건물운영에 점차적으 로 비중을 강화하고 있다. 통합 디자인 자체에 대한 지원과 자료 데이터베이스를 운영하여 성능기반 건축물 시장으로의 빠른 재편과 신산업 육성을 기대하고 있다. 안정적인 제도 운영을 위하여 재원확보가 필수적인데, 세금이 가장 일반적이고, 에너지 사업자 지원 또는 에너지 사용량에 따른 누진제를 통해 재원을 확보하는 보다 적극적인 재원확보 방안도 제시되고 있다. The purpose of this paper was to comparatively investigate the efficient building incentives in Korea and foreign countries and to seek strategies to enhance low energy building integrated design market infrastructure in Korea. The structure of incentive policies were composed of four main component: 1) types of financial aids and beneficiaries, 2) energy performance criteria and verification methods, 3) supports for low energy building integrated design, and 4) funding sources for incentive programs. Every overseas incentive program has adopted a design team incentive along with building owners incentive and the range of target buildings have been extended from new construction to remodeling projects. The main system of the program is the performance standard through which projects were investigated and the level of incentive are decided. Initially, the integrated performance has been investigated through simulation methods, but the construction performance evaluation and energy monitoring methods are emerging. In addition, the direct support and educational support for integrated design has been provided to enhance the foundation of relative markets. Financial funding is also a key component of the program and more aggressive funding strategies have been adopted.

The purpose of this paper is to investigate energy saving and comfort enhancement potentials of a envelope performance improvement and natural ventilation in Korean Traditional Houses. User’s preference to detached house increased recently and comfort and low-energy consumption are the core requirement, so the strategies for both environmental performance should be researched. At first, this paper simulate energy consumption in three envelope performance levels in a typical linear shape house found that the proportion of cooling energy demand is sharply increased in a well-insulated and air-tight envelope and the cooling energy demand could be reduced by natural ventilation. The comparative analysis of energy balance in three types of Hanok shows that linear type recorded the lowest heating energy consumption thanks to the highest solar insolation and it resulted in the highest cooling energy consumption in spite of the largest natural ventilation potential. The enclosed type recorded the lowest natural ventilation potential and the slightly higher cooling energy consumption compared to the semi-enclosed type one. The air change rate in the living room was above 5 ACH and shows the cooling potential in linear and semi-enclosed type Hanok. PMV in all types of Hanok shows the improvement during cooling season. The whole integrated passive cooling strategies including natural ventilation should be researched in the future.

In order to investigate devolatilization characteristics for ashless coal with relatively low ash content and high heating value, an experiment was performed in different bed configurations of TGA and DTF(Drop Tube Furnace) at atmospheric pressure condition. The heating rate was 10℃/min up to 950℃ in TGA, while temperatures varied from 500 to 1300℃ in DTF. A weight loss and particle temperature were obtained to be used for kinetic analysis of the devolatilization. The kinetic parameters including an activation energy and pre-exponential factor for ashless coal were obtained using Coats-Redfern method in TGA and single step method in DTF. Furthermore, the devolatilization kinetics of the ashless coal were compared with the results of different kinds of conventional coal such as sub-bituminous and bituminous.

어촌체험관광마을은 주민소득 증대 및 도시인에게 휴식·여가 공간의 제공을 목적으로 하는 것이지만 계획적이고 체계적인 어촌체험활동을 하기란 쉬운 일이 아니다. 그리하여 이러한 체험프로그램에 대하여 체험프로그램 위탁운영제도 도입, 축제기획에 주민참여제도 확대, 축제프로그램과 연계한 체험형 이벤트 개발, 홈페이지 관리능력 향상, 체험프로그램에 대한 컨설팅 실시, 활동적인 체험마을 적극지원 등이 요구되며, 지속적인 교육과 창의적 발상을 위한 개별적 노력이 요구될 뿐만 아니라 지역 리더들을 중심으로 일정교육을 통한 전문가로 양성할 필요성이 있기에 지자체를 이러한 문제를 감안하여 하루 빨리 ‘농어촌체험지도사’ 양성프로그램을 운영하여야 할 것이다. Experience tours of Fishing Village in Sokcho and some suggestions for its success The major purpose and role of the fishing village experience project are both to bring more income to the village residents and to provide the city dwellers with valuable chances to enjoy live entertainment and wonderful repose exploring farm life. However, it is not an easy task to present some productive and systematic fishing experiences to the visitors. To deal with this difficulty we suggest several approaches like introduction of professional experience program management, encouragement of people’s participation during the festival, development of experience events in tandem with the festival, consulting and supporting competitive experience programs. The hosting villagers should be qualified as service professionals through continuous education programs, self development efforts, and creative ideas. The authorities concerned should consider the importance of these requirements and take timely steps to run a farm and fishing village experience specialist program.
