To reduce the building energy consumption, the major advanced nations are conducting actively many researches on so called a "self-sufficient building(or other words zero energy building)" which can support its required energy by itself. Given this background, KIER(Korea Institute of Energy Research) built full size test-bed of the zero energy solar house in early 2002, and has studied on the self-sufficient heating load up to now. We analyse the sensitivity between the heating load and the solar radiation gain according to the change the effective transmittance of windows. The authors classified 9 cases by solar transmittance of glass. The results demonstrate the solar radiation amount is 0.466 MWh from the eastern zone of Fl.,1(the first floor), 0.332 MWh from Fl.,2(the second floor), 1.194 MWh form the southern zone of F1., and 0.822 MWh from the southern zone of Fl.,2 on the case 1(each cases are classified by window types). On the case 9, the solar radiation amount is 3.127 MWh, 2.662 MWh, 8.799 MWh and 6.078 MWh from the same condition. For the Fl.,1, the amount of Heat Load that is saved per year ranged 10.5 to 48 %, and the reduction was anywhere from 0.2 to 17.9% for Fl.,2.

This study reviewed a concept of Korea-type zero-energy building and a promotion strategy for reaching its goal and proposed a design process for systematically introducing an element technology by phase based on the project implemented for the technology development and demonstration of the domestic zero-energy buildings. The proposed design process was limited to the phase from building planning to final design and the consecutive approach and phase-specific considerations and the technical identifications were also presented. According to the result of this study, it's important to set a goal in the planning phase for implementing the zero-energy building and it's necessary to systematically apply the element technology by phase. For these purposes, the design phase-specific energy performance should be analyzed based on the objective data on whether the goal of project was carried out or not and then the progress towards the next phase was decided by conducting the review and evaluation on the analysis result would meet the goal of project. In order to implement the zero-energy building as such, this study tried to use the integrated design process to meet at the same time the building energy performance and the design as the basic data for implementing the Korea-type zero-energy building.

Leading developed countries have studied energy self-sufficient houses such as zero or low energy buildings to reduce energy consumption for buildings since the early 1990s. Moreover, some developed countries have actually constructed self-sufficient houses and operated them for demonstration, expanding use of such houses. Korea has also established Zero Energy Solar House(ZeSH) and studied energy independence. Therefore, this study analyzed research result regarding ZeSH, self-sufficient energy house hold of Korea, found out technologies used for heating energy independence, used building interpretation program(ESP_r) to evaluate performance of each factors and analyzed energy reduction quantitatively. Results from the research are as follows: Reduction rate of actual detached house's heating load was also analyzed quantitatively depending on application of each technology. When each factor was applied step-by-step, annual reduction rate of heating load depending on increase in insulation thickness reached 6.6~22.2 %. Annual reduction rate of heating load depending on increase insulation thickness, and change in window heating performance and area ratio reached 31.5 %. Annual reduction rate of heating load through high-sealing and high-insulation depending on change in leakage rate reached 40.0~88.9 %. Annual reduction of heating load, when Mass Wall and attached sun space was applied were applied reached 28.5~39.2 %, respectively.

This study analyzed the interrelation of effects that the proportion between window performance and window area and the window performance and inner heating conditions in commercial building have on the energy demand in building with using EnergyPlus, a building energy simulation tool. The conclusions identified through this study are as follows: There was no any specific type interrelation between the proportion of window area and the energy demand according to window performance, but it was found that the bigger the proportion of window area, the higher the sensitivity depending on SHGC. In addition, as for the interrelation between the inner heating value and the energy demand according to window performance, it was analyzed that the bigger the inner heating value, the higher the impact of the SHGC of window. In summary, the energy demand of building is influenced by a variety of variables including window area ratio, window performance and building operation characteristics, so a rational design plan on the relevant project should be identified by using an integrated energy simulation-possible tool from the planning phase of building.

본 연구는 「유치원 교육활동 지도자료」에 나타난 수준별 교육활동을 분석하고 수준별 교육과정의 운영실태 및 교사의 인식에 대하여 조사하여, 이를 바탕으로 유치원에서의 수준별 교육과정 평가척도를 개발하기 위한 방향을 모색하고자 하였다. 지도자료에 제시되어 있는 수준별 활동의 경향을 분석한 결과, 수준별 활동의 생활영역별 교육내용에 따른 분포와 교육과정의 내용영역이니 생활주제 그리고 활동의 유형별로 활동 수준이 편중되어 제시된 경향이 있음을 알 수 있었다. 175명의 유아교사를 대상으로 유치원 수준별 교육과정의 운영실태 분석 결과 소속기관(공립과 사립 유치원)에 따라 일부 문항에서 유의한 차이기 있는 것으로 나타났다. 또 지도자료 분석과 운영실태분석 결과를 토대로 평가척도 개발을 위한 방안이 모색되었다. The purpose of this study was to explores the preliminary study on the development of assessment scale for the differentiated curriculum of kindergarten. Research questions are as followings. First, what is the trend of differentiated activities in 〈the guide for educational activities and materials for kindergarten〉. Second, what are the opinions and suggestions of early childhood professionals about management and perception of the differentiated curriculum of kindergarten. Third, what and how co develop the assessment scale for the differentiated curriculum of kindergarten. For this first purpose, the meaning and practical problems of differentiated curriculum in kindergarten were explored, and the differentiated activities in terms of content area, life subject, and activity type in 〈the guide for educational activities and materials for kindergarten〉 were statistically analyzed. For second and third purpose, the questionnaire of the management and perceptions of the differentiated curriculum of kindergarten was collected and statistically analyzed.

The majority of fixed shading devices are installed in the exterior of a building in order to dissipate the heat that they absorb from the sun to the outside air and to prevent the direct sunlight. In designing external shading devices for windows, there are many requirements that must be considered simultaneously ; solar geometry, optimum energy performance, multi-purpose usage and design factors etc.. In order to satisfy these requirements, we suggested the folding shading devices and its optimum design methodology. Also we analyzed the thermal performance using the IES_VE program according to the various operating modes and compared with the existing shading devices. The results are that this device could save about 1.90~22.40% in cooling load and about 1.09~24.22% in heating load in comparison with the existing ones.
