  • This study aims to evaluate the correlation between vertical solar radiation and the level of heating load according to the location and type of housing in multi-family apartments. This study shows that heating load is related with factors such as wall loss, window loss, ventilation loss and solar radiation gain. The heating load increases in the order of the middle floors, the highest floors and the lowest floors. The lowest and the highest floors are the most vulnerable floors, and it should be as emphasized as the middle floors. The heating load saving proposal contains 52 Alt. that shows heating load savings from min. 4% to max. 49%. The goal is to reduce the heating load of the highest and the lowest floors to the level of the middle floors. The result showed that there are 3 Alt. for the lowest floors and 16 Alt. for the highest floors as the heating load saving proposal. This study suggests integrated application to compose saving elements of heating load. so it could be utilized as a data for the construction of passive houses.

  • Global environmental problems are growing, and the importance of buildings with high energy consumption has been emphasized. In Korea, the Ministry of Land, Transport and Maritime Affairs has been promoting the mandatory zero energy building since 2020, and guidelines related to the zero energy building have been developed. In addition, based on the "Energy-saving Design Criteria for Buildings" of the "Green Building Promotion Act" in Korea, the standards for energy-saving design are specified and the energy saving plan is written. Besides, the 'Energy-saving construction standards for eco-friendly houses' also specify insulation, machinery, equipment, and sunshade. Also, there is little consideration about the cost such as construction cost and material cost which should be considered important in the construction stage. Therefore, this study aims at analysis of building type and energy performance versus materials for energy saving building design considering energy performance in planning aspect of initial design stage. In this study, because the variables can not be neglected in this study, it is selected as the lecture facility of the 'K' university campus building which can consider the remaining factors except the passive design element as the control variable, Energy performance analysis.

  • 에너지 절약은 자원의 부족 및 한정성으로 그 중요성이 더욱 증가 하고 있는데 반해 교육 현장에서 에너지 절약에 대한 학습 현황은 부족한 실정이다. 특히 초등교육에서 에너지 절약에 관한 교육은 실천으로 연결되지 못하여 교육 효과가 미흡한 것으로 나타났다. 학습 도구로 여러 가지가 활용되고 있지만 해외 산업분야에서 에너지 절약을 위한 게임화 전략의 성공 사례가 다수 소개 되고 있음에 착안하여 에너지 관련 교육을 게임을 통해 할 수 있도록 게임 디자인을 제안한다. 에너지 절약은 실천을 하지 않으면 효과를 볼 수 없기 때문에 교실에서의 지식 전달 위주의 학습보다 게임을 도구로 활용한 학습이 효과가 높을 것으로 기대 된다. 에너지 절약 교육용 게임을 디자인하기 위해 선행 연구에서 제안된 교육용 게임의 재미 요소인 미션수행 요소, 점수 획득 요소, 시간제한 요소, 캐릭터 요소를 활용하여 교육용 디펜스 게임을 디자인하였다.

  • In this paper, the conceptual framework of IBS(Intelligent Building Systems) is redefined, and we propose two ANP(Analytic Network Process) models for ranking IBS. Traditional models have ranked IBS according to technical features or the number of elements in IBS. But, we consider relative functional importance among IBS elements for efficient building operation. According to the structure of interactive-relationship among IBS elements, we present two types of model. The one is Model A that is composed of both hierarchical and network structures. It has $12{\times}12$ supermatrix consists of interdependent relationship between 6 benefit elements(Productivity, Saving, Safety, Convenience, Pleasantness, Environment Affinity) and 6 IBS elements(Building Operation, Security, Safety, Telecommunication(TC), Office Automation(OA), other elements). Each of 6 IBS elements has subelements in hierarchical structure. The other is Model B that has $25{\times}25$ supermatrix consists of interdependent relationship between 6 benefit elements and 19 IBS sub elements. Merits and demerits of each model are discussed in detail.
