        • 부하 시뮬레이션을 이용한 건축적 요소기술의 민감도 분석

          이정재,박주양 東亞大學校 建設技術硏究所 2009 硏究論文集 Vol.32 No.2

          To meet the increasing demand with the limited resource, every country is trying all-out to find a solution. A large part of energy demand is used in the building, so a Korean Energy Saving Design Standard which is right to the country conditions is immediately needed. This study is trying to analyze the sensitivity of architectural elements through a simulation which considered architecture, electricity, machine overall with the typical thermal load analysis program Transys and to present a quantitative data to set up an adequate Energy Saving Design. The results of this study are as follows. Sensitivity analysis show that setting windows are more sensitive than other factors which we adopt at cooling load, and setting temperature are more sensitive than other factors which we adopt at heating load. 2005 년 2월 16 일 각국의 온실가스 감축을 의무화 하는 교토의정서가 공식 발효됨에 따라 2013년 이후 감축의무 이행이 불가피해질 우리나라는 온실가스 저감을 위한 추가적인 대책이 없을 경우 온실가스 배출량은 2000년 대비 2030년까지 25~90% 증가할 전망이며, 에너지 사용으로 인한 C0_(2) 배출량은 같은 기간 동안 45~110% 증가할 것으로 예상된다. IPCC WG3 보고서에 따르면 현재 우리나라 건물부문의 경우 부문별 온실가스 감축 잠재량이 타 분야와 비교해 가장 큰 것으로 나타나고 있다. 따라서 의무 감축 국가 편입에 대비하여 건물에너지의 감축비용, 감축 잠재량 등을 면밀히 분석하고, 이를 통한 감축목표 설정 등 체계적인 추진 전략이 필요하다. 이에 현재 전 세계적으로 건물 저에너지 요소기술의 적용을 통해 건물 에너지 소비량 절감 에 의한 목표 C0_(2) 감축량을 달성하기 위한 연구 및 개발이 활발히 진행되고 있다. 이러한 현실에 대응하여 우리나라도 건물 에너지 절감에 대한 필요성을 인식하고 여러 가지 저에너지 요소기술들을 개발하고 있다. 건물 에너지절감 요소기술은 크게 건축 계획적 요소기술과 건축설비관련 요소기술 그리고 건물 유지관리 요소기 술로 나눌 수 있다. 특히 건축 계획적 요소기술은 원천적으로 건물에 발생하는 냉난방부하 저감을 통해 에너지를 절감한다는 측면에서 매우 중요하다. 이에 본 연구에서는 건물에서 발생하는 에너지 소비를 줄이기 위해 건물 용도별 에너지 소비에 많은 부분을 차지하고 있는 사무소건물을 대상으로 Tmsys를 이용하여 건축 계획적 요소기술인, 실내설정온도, 방위, 차양길이, 창면적비 감소율, 단열재 두께, 필요 환기량, 창의 종류를 변수로 선정하고 그에 따른 인자들의 변화를 통해 부하를 산정하여 민감도를 분석하고자 한다.

        • 효율적인 신호교차로 운영방안에 관한 연구

          황인식,오세경 東亞大學校 建設技術硏究所 2007 硏究論文集 Vol.31 No.1

          This study was intended to increase efficiency of traffic flow management on intersection. The result suggested to establish a left-turn at own risk lane to increase efficiency of traffic flow on intersection. The scope of the research was to investigate the geometric structure of a signal-controlled intersection, traffic volume(density) with respect to directions and traffic signal display, and to select a signaling intersection into which a car waiting for a traffic signal enters by adjusting the display sequence of traffic signal. The delay with respect to directions and for the whole intersection was compared for the current situation and an improvement plan. Using TSIS, a traffic analysis package, the traffic situation on an intersection was investigated. Based on the simulation result for Seok-Jeon intersection in Ma-San selected from the field investigation of intersections to which an improvement plans would be applicable, the waiting time in the direction without a entering traffic signal was decreased to be 78.6 seconds per car and that of the direction expecting the increase of waiting time was increased by 4 seconds per car only. It was confirmed that the waiting time for the whole intersection was improved.
